Inspired by a Russian, first made by a Hungarian, who was succeeded by a Frenchman and then a German, the winemaking lineage at Masseto has been decidedly international – until now, that is. Since January 2024, the leading Super Tuscan and Ornellaia’s sibling estate has had its first native at the helm: Marco Balsimelli – born in Arezzo, not far from Siena, took the reins from longtime Production Director Axel Heinz.  Balsimelli comes with his own illustrious pedigree, having long been based in Bordeaux, working at Gruaud Larose and, since 2010, alongside the famous Eric Boissenot as a consultant winemaker to many of the region’s leading estates, but the chance to work at Ornellaia and Masseto – iconic names from his Tuscan homeland – was an opportunity he couldn’t turn down.  It was André Tchelistcheff (the Russian-born Napa winemaker) who first suggested to Lodovico Antinori that a particular hill on the Ornellaia estate would be perfect for Merlot. Tchelistcheff was consulting for Antinori, and recognised the potential of the parcel of blue clay – the same soil that is synonymous with Pétrus. Back then, in the 1980s, Merlot was barely planted in Tuscany and remained an unknown quantity in the region, with only Castello di Ama – based further inland in Chianti Classico – having some vines (today used for its flagship L’Apparita). Nevertheless, the Ornellaia team took a chance and planted most of the seven-hectare swathe of clay in 1984 (additional planting took place in 1995).  The first vintage of Merlot from the site was made in 1987: Masseto was born. The name comes from “masso”, Italian for rock, after the large boulder-like clumps of clay that dot the vineyard’s surface. It didn’t take long for the wine to earn international acclaim, with Wine Spectator giving the 2001 vintage 100 points, and its place was cemented in vinous history.  Although Tchelistcheff consulted until 1989, replaced by Michel Rolland from 1991, Hungarian Tibor Gál was the property’s first winemaker. Gál was succeeded by Thomas Duroux (now of Ch. Palmer), who in 2005 passed the baton to Axel Heinz, the German-born winemaker who preceded Balsimelli. The property has changed hands over the years too, with the Mondavi family taking a share in 1999 before buying it outright from Lodovico Antinori, and selling it onto the Frescobaldi family, who took full ownership of Ornellaia and Masseto from 2005.  Much might have changed, but the terroir hasn’t. “It’s a very special site,” Balsimelli tells me. The all-important clay dominates the topsoil, which is only about a metre deep. When it rains, the clay swells, making it near impossible for the vines’ roots to develop. High sodium levels in the soils only accentuate the problem. “For the roots, it’s a battle every day,” he says. It’s that struggle, he feels, that you can taste in the concentrated, high-acid fruit from the site.  The climate is key too, lying just 10 kilometres from the Tyrrhenian Sea. Fresh marine breezes mean the temperature is around 5°C lower than that in central Tuscany, with a drop of circa 15°C from day to night. Combine this with the light reflected off the sea, and you get a long growing season, preserving aromatics and acidity, yet encouraging phenolic ripeness – wines that combine perfume and power. Surrounded by forest, there is a reason that Masseto is run as an entirely separate project to Ornellaia, with its own unique identity – even if it has always shared a winemaker (and, until 2019, a winery) with its sibling estate.  For Balsimelli, the project has provided a fresh challenge. The shift away from a consultant role – no longer offering advice before moving on to the next project, but sitting with each and every decision – adds a new weight of responsibility. “I spend a lot of time thinking about the technical questions and the consequences,” he tells me. Since most of his work with Boissenot had been based on Bordeaux’s Left Bank, focused on Cabernet-driven blends from larger estates, working with a small property, focused on just one variety and various sub-plots is a different sort of jigsaw puzzle. The approach, for him, is much more Burgundian – all about expressing the purity of the site and its blue clay. “You have to be perfect with only one type of soil and one grape variety,” he explains.  The quest for perfection was started long ago at Masseto and today the vines average between 20 and 30 years in age. They’ve also been moving from cordon-trained to bush vines – first trialled in 2008 and something which they have found helps temper the effects of global warming (coping better in dry conditions and shading the fruit from the heat of the sun). Farmed organically since 2012, there has also been a significant focus on encouraging biodiversity across the site, including using cover crops to reduce soil compaction, increase organic matter and retain humidity in the soils.  Balsimelli’s first vintage was 2024, which won’t be released until 2027. But he’s clearly excited by the site, as well as how he can tweak and improve a wine that is already lauded by critics and consumers. “When you taste old vintages of Masseto, you can feel the legacy, taste the terroir,” he says – and that’s exactly what he wants to do moving forward, channelling the Boissenot philosophy: understanding a piece of land and finding the best solution to express it in the glass. For him, that solution will be all about accentuating the wine’s elegance.  He notes how there was – across the world of wine – a trend towards low yield and high levels of maturity in the early 2000s, but his preferred vintages are those that saw more balance. The 2006, for example, is his favourite at the moment – a year with more rainfall, more vigour, and – he feels – more energy as a result. It’s a vintage that he believes is “the key for the future”.  The site is one that can ripen quickly, and he plans to focus on freshness, maybe picking a little earlier, reducing extraction and lowering temperatures for maceration. The 2022 is the vintage set to be released this September – a wine that Balsimelli notes shows just how good the site is – performing even in tricky conditions such as 2022’s hot growing season. It is, he says, “the magic of Massseto”. Magic it may be, but Balsimelli is set on elevating this special estate even further.   Explore all current listings of Masseto or read more Editorial

The magic of Masseto

There are myriad fascinating twists and turns in Scotch whisky’s long and storied past. From dizzying boom times to disastrous downturns, the distilling landscape – and the major players within it – has been redrawn countless times. 
There's one era, however, that is legendary – whisky's "golden age". Between the 1950s and '80s, some of the industry's most nuanced single malts were crafted. These are now widely regarded as the greatest ever released, which is reflected in the eyewatering secondary market prices – should they ever appear on the auction block. 
These perfectly imperfect, characterful and wonderfully unique liquids, produced at distilleries that no longer exist, or exist in a very different way today, will never be bottled again – making them real unicorns for whisky collectors. 
To understand what makes them so special, it is important to first appreciate just how little liquid exists from this time. The single malt whisky market was unfathomably small before and during this period and entirely dwarfed by blends. A mere fraction of a distiller’s finest liquid would be bottled as a single malt. These minuscule quantities were also made via practices that are now lost in the annals of history, making them more desirable for collectors. 
For context, Scotch whisky was largely made as it always had been until the 1950s, drawing on traditional methods that had been passed down for centuries. Distillers would use their sight, smell and taste to determine when a liquid was ready to cask, and later, bottle. Whisky-making took mastery and patience – something producers could ill afford when demands on the industry intensified and there was a concerted push to produce more for less during the 1970s. While many producers made these changes around the same time, they didn’t all happen at once, creating a wonderfully varied time capsule of whiskies. 
The 1960s – when some of these great bottlings were produced – was sandwiched in between two vastly different decades. Production in the ‘50s was steady but small. By the 1970s, however, distillers – both large and small – were forced to increase their output by almost double, and names that had fallen silent were reawakened once more as global demand for Scotch whisky grew. 
Sadly, by the mid-1970s, the tide started to turn. The bountiful supply of whisky was not met by demand, resulting in a devastating whisky loch in the 1980s and some of the most difficult years the Scotch whisky industry has ever endured. Swathes of distilleries were forced to close, including the now-legendary Port Ellen and Brora – both of which shut their doors in 1983. This depression continued well into the 1990s with a further 20 casualties (of these, only three ever reopened), before the pendulum finally swung back in the early 2000s when the seemingly unquenchable thirst for single malt whiskies, that is still in full force today, began. 
From the 1950s onwards, holders of the increasingly frayed purse strings sought to reduce inefficiencies in the traditional, labour-intensive practice of whisky-making – which defined the golden age. With the introduction of modern, more mechanised, safer processes, it was a new dawn for Scotch whisky.  During this period in history, every single stage of whisky production was “streamlined”. The money men closed floor maltings, introduced distillers’ yeast, reduced fermentation times, installed semi-lauter tuns, made the switch to indirect-fired stills, replaced worm tubs with shell-and-tube condensers, and introduced ex-Bourbon barrels. By the end of the 1970s, you could almost count on one hand the number of distillers who retained traditional methods. 
It’s important to remember that tweaking one of these processes can alter the entire flavour profile of a whisky – just ask Glenfarclas who reverted back to direct-firing their stills after their new-make spirit lost its characteristically heavy and oily profile during their ill-fated flirtation with steam in 1981. And yet, in many instances, producers permanently changed many of these processes. Traditional practices and know-how that varied slightly at every distillery began to be outsourced as they turned to professional maltsters and installed modern, industrial-scale equipment that increased efficiencies and consistency but in some cases compromised the craft and character of the final spirit profile. 
“Every distillery has its own story and evolution of style,” whisky authority Serge Valentin explains, “their own ups and its downs.” 
Valentin was ahead of his time when he started collecting single malt Scotch, almost exclusively from Old Clynelish and Brora. He couldn’t possibly have predicted what his passion project of buying as many different bottlings as he could “simply because they were [his] favourites”  would become. 
Both Clynelish and Brora – as it would be known – produced heavily peated malt during the late 1960s and early ’70s. Bottlings from this time until 1983, when Brora became a victim of the whisky loch and fell silent, have become highly collectable in recent years. Old Clynelish bottlings, (Valentin’s favourites), which are robustly distinctive with aromas of scented wax and heather, are astonishingly rare and modern collectors clamber over one another to get their hands on these golden-age gems for many times the price Valentin would have paid. 
Stephen Rankin has been fortunate to sample whiskies from one of the most remarkable single malt libraries in the world at Gordon & MacPhail. His team is able to pull out liquids from what he calls “pre-evolutions within distilleries” thanks to his family’s foresight to buy barrels from cash-strapped producers who were selling their stocks for survival. The Elgin-based independent bottler had the luxury and fortitude to bide their time and store casks that would otherwise have been bottled young or blended. He has a particular affection for single malts from what was Milton Distillery, known since 1951 as Strathisla, which he describes as a “great example of a whisky that has the flavours of this past era.” 
Independent bottlers like Gordon & MacPhail played a vital role in bringing many of these now-legendary whiskies into the world. One man in particular, Silvano Samaroli, was responsible for bottling single malts that are now widely regarded as some of the greatest ever released.  
Rome-based Samaroli released his first Scotch whisky series in 1968 in the form of the now-iconic, dumpy Cadenhead bottlings – making him the first independent Scotch whisky bottler outside the United Kingdom. Today, Samaroli’s Bowmore, Glen Garioch, and  Springbank releases are held in especially high regard and his  Laphroaig single malts from 1967 and 1970 are in a league of their own. 
“The late 1960s to the ’80s is definitely one of the most remarkable periods,” Samaroli’s Daniele Liberati says, “largely due to the appearance of certain expressions for the first time.”  
“We started to propose different bottlings, moving away from the classic blends and official distillery releases,” Liberati adds. These included single-cask expressions, numbered bottlings and cask-strength releases, all of which are commonplace today but were revolutionary at the time.
 
In recent years, a handful of new distillers have turned to old whisky-making practices in an attempt to recapture some of its magic. Fledgling Speyside distiller Dunphail, for instance, has faithfully – and at great cost – installed traditional floor maltings, direct-fired stills and wooden, open washbacks where fermentation times are considerably longer than the industry average, to produce a fruit-forward, oily, medium-bodied Speyside whisky. Today, however, these traditional methods are always adopted in conjunction with modern practices in order to achieve all the desirable characteristics of yore in a more efficient way.   While there is the temptation to look back on this era with a rose-tinted view, as there are undeniably some exceptional bottlings from this time, it is wrong to believe that all whisky produced in the golden age was of the same standard. Whisky-making 40 to 50 years ago was imperfect, there was very little consistency in quality and for one good cask, a distiller would likely have 10 or 20 bad ones that never saw the light of day.  It’s also important to appreciate that many of these modernisations were vital to guarantee the safety of distillery workers as several stages in production were unstable. These advancements have also resulted in unprecedented consistency. While nuance and singularity might have been sacrificed, it’s now incredibly hard to find a bad dram.   As times evolve – as they inevitably do – it’s highly unlikely whisky from Scotland’s golden age will ever not be considered precious.    Browse all Scotch whisky or read more Editorial

The golden age of malt whisky

The golden age of whisky

It’s not often words fail me. But finding the right words to describe Dr Bill Lumsden to those who haven’t had the great fortune of meeting him has rendered me a little dumbstruck. Many have dubbed him the “Willy Wonka of the whisky world” for his creativity, jaunty style and flair. His latest project, a purpose-built home for innovation named the Lighthouse, where Lumsden can innovate to his heart’s content and create all manner of whacky and category-bending whiskies, somewhat perpetuates this narrative of the eccentric whisky-maker. But, I’d argue, the good doctor is far more than this. He is, first and foremost, an incredibly accomplished scientist. His work at Glenmorangie and Ardbeg over the past 26 years – maintaining the iconic distillery characters and launching innumerable products for each – is nothing short of sensational. He is a workhorse, as well as, it would seem, a bit of a clothes horse. “I’m a bit of a shopaholic,” he tells me with glee. “I love buying clothes.” This isn’t the sort of confession I expected when sitting down with the Director of Distilling, Whisky Creation & Whisky Stocks in November last year. “If something’s in fashion, I wouldn’t be caught dead in it because other people are wearing it,” Lumsden continues. “So I tend to wear things which have been out of fashion for many years or are yet to be in fashion – and it’s just a little facet of my personality, unfortunately.” This, while slightly unexpected, actually makes a great deal of sense when you cast an eye over his professional life. Lumsden has always been the trendsetter rather than the disciple. And he’s quick to assert that his avant-garde attitude extends beyond apparel. “I have absolutely no interest whatsoever in what’s in fashion and what’s not in fashion [in the whisky industry]”, he says. “When I’m doing something it really is all to do with will I like the taste at the end of the day? Will it complement that character of the Glenmorangie or the Ardbeg spirit?”. Since joining Glenmorangie in 1995, Lumsden has been charged with “maintaining and hopefully slightly improving the spirit character” and innovating. While once his role was divided equally between these two tasks, new product development and innovation now take up the majority of his time. “It’s got to the stage now where the demand for new products is almost impossible to keep up with,” he says matter-of-factly. While this might be fatigue-inducing for some, this constant pressure to innovate exhilarates the inquisitive doctor. “I’m a scientist by training,” he explains. “It’s in my blood to experiment, and I’ve always been a curious individual who gets bored very easily and likes to try new experiences, in every aspect of my life. So the move to Glenmorangie was heaven-sent for me from that perspective,” he says with unfettered glee. The decision to build Lumsden’s Wonka-esque Lighthouse was driven to a certain extent by necessity, he tells me. “The Ardbeg and particularly Glenmorangie distilleries have been running absolutely flat-out for the last 12-15 years,” he says. “For me to interrupt the production cycle to get access to the distillery for three to four weeks of a year, where I wanted to try some radically different things was proving increasingly difficult. And also some of the things I wanted to do, I just simply hadn’t been able to do that with the existing distillery plant. “So the Lighthouse has been established to allow me to experiment but while maintaining the volumes that are required for future bottlings and also to try things that I simply can’t do in the main distillery.” These things range from the smallest alteration in primary production to radical innovations, and everything in between. “Some of the time it can be a very, very simple change,” Lumsden tells me. “It can be something as simple as offering one of your expressions in a natural, cask-strength form, for example, and other times it can be something dramatically different, where you’re actually using completely new materials. I am continuing to experiment with just about anything you can think of.” For the past 10 years, this experimentation has largely focused on different aspects of production. “We’re about to see some products coming out for both the Glenmorangie and the Ardbeg brand where I’ve been playing around more with primary production – it’s been great fun,” he teases. The challenge with this approach, he says, is two-fold. “You’ve got a very long lead time until your product comes to market,” he explains. “Sometimes you’re talking 10 years’ maturation.” At the very least. If you’re experimenting with barley varieties, or looking at fermentation profiles, you have an even lengthier wait. Secondly, by the very nature of these experiments, the difference between spirits is most emphasised in the new-make. “For example, using the barley varieties, it’s not giving you black and white differences,” Lumsden explains. “It’s more shades of grey, and you really pick that up in the new spirit. “But after many years of maturation, you risk losing these differences. So you have to choose your cask type accordingly to try and make sure that you still have the point of difference coming through.” Lumsden says Glenmorangie is launching a product in 2022 that is an experiment he’s always wanted to carry out. “I did this many, many years ago. I can’t say any more about it at this stage, but I will probably bottle this [whisky] slightly younger than my original target, which was 12 years, because I don’t want to continue to minimise the difference in character, if that makes sense?”  In addition to maintaining the two distillery’s very distinct characteristics, and inventing all manner of whiskies, Lumsden sits on a number of prestigious judging panels. In this capacity, he tastes hundreds upon hundreds of whiskies and sees first-hand the changes in the industry and trends that are being adopted – good and bad. He says there has been a “real divergence” in recent years. “Some of the whiskies I taste have become much more characterful and I’m delighted to see whiskies that are non-chill filtered,” he says hopefully. On the controversial subject of chill filtration, the process whereby distillers remove esters and fatty acids to prevent the liquid clouding at low temperatures, Lumsden ardently believes less is more. He does, however, acknowledge its place in markets where drinkers might not understand that cloudiness is caused by oils coming out of suspension rather than a fault. But, he believes, producers are taking its use to the extreme. If Ardbeg and Glenmorangie whiskies are chill-filtered, it is only ever done so “very gently”, because Lumsden feels that lipids – fatty acids from the base barley that would otherwise be removed by full chill filtration – add texture and character to the spirit. Sadly, he rues, this is not true for others who are “very brutally” applying this technique to hasten up processes, and character is lost as a consequence. Corner-cutting exercises like this, speeding up distillation methods and reusing barrels too many times are becoming all too common, he says. When it comes to producing or judging a perfect whisky, Lumsden says he’s after complex harmony. “I’m looking for the flavours to be nicely integrated together and not having any one aspect dominate,” he says. “That’s what I think good quality whisky, particularly Scotch whisky, should be". “The final thing I’ll look for is the length and character of the aftertaste of the whisky,” he explains. “Because I really don’t like to see a whisky just completely fade – it shouldn’t do that. It’s a richly flavoured product and it should linger on the palate for a while.” Whether he’s sitting on a judging panel or looking out from his monstrously tall Roald Dahl-esque Lighthouse, Lumsden’s vantage point, you sense, will always be forward-facing and progressive. It is for others to catch up or catch onto the trend. Browse Ardbeg and Glenmorangie whiskies or read more Editorial

Dr Bill Lumsden: the eternal inventor

Last year, the great and the good gathered at the ancestral home of the legendary Gordon family (of William Grant & Sons). A hearty dram was poured for the world’s foremost drinks authorities and they were asked to name the liquid within. So far, so normal in the Scotch whisky world. What happened next is quite unusual. Not one of the experts – with decades of experience and dozens of book credits to their name – could so much as hazard a guess.   The answer to the seemingly simple but dastardly question dumfounded them all. The as-yet-unidentified liquid was a single grain Scotch whisky that had slumbered in a lone Sherry butt for 53 years. Now almost jet-black in colour, the single grain had taken on incredible, rich notes of dried fruits, roasted coffee, and muscovado toffee – and it was indistinguishable from a greatly aged single malt.   The Cask Trials, which is the name given to this highly unusual liquid that left some of the finest palates awestruck and not-so-secretly hoping for a bottle in their gift bag, is just one of the panoply of independently bottled House of Hazelwood releases from the Gordon family’s private Scotch whisky archives.   Somewhat surprisingly, you won’t find a single malt among them. These rare whiskies, which have been amassed over the past 100 years by the owners of Glenfiddich and The Balvenie, were released to the public for the first time in 2022 in two, painfully scarce, collections. The Charles Gordon Collection (all priced above £3,000 per bottle and aged for at least 40 years), and the Legacy Collection (priced between £950 and £2,000 a bottle) are all well-aged blended Scotch, blended grain and blended malt whiskies that have been matured in the most novel ways.   “Bringing old, expensive and unusual blended whiskies to the market is slightly counterintuitive,” House of Hazelwood Director Jonathan Gibson – who was instrumental in creating the range – candidly tells me. “It's not overly common within the industry.”  It’s also not overly common within the industry to bottle liquids of this age and provenance with playful names such as "Blended at Birth", "Sunshine on Speyside" and "The Old Confectioner’s", in understated packaging at these price points.  The liquids are undeniably scarce (once they’re gone, there really is no more) and old (few are under 40 years of age, and the oldest tops 50 years), but they are undeniably unusual and at odds with the highly successful formulaic approach others have followed of encasing precious liquids in highly ornate, priceless vessels that weigh more than a small child.    “They're not concept releases,” Gibson explains. “Everything is driven by the whisky. The packaging is quite straightforward. It's a nice bottle and it's classically engraved but we haven’t collaborated with the hottest designer. The idea is really just to give the whisky room, provide a platform, without overshadowing it,” he adds.   “Over the past 10-15 years – and it's no bad thing at all – you can see a lot more old age-statement single malts coming onto the market,” Gibson says, “And typically they're very straightforward in terms of their naming. It's distillery name, plus age statement equals a certain financial value.  “The naming of these releases is slightly playful, but actually if you look at them one by one, they're very straightforward. It's not quite a Ronseal, ‘it does exactly what it says on the tin’ approach, but it's not too far away from that. If you said ‘Blended at Birth’, it could be seen as quite playful but it's also quite descriptive and the same for ‘The First Drop’ and ‘Sunshine on Speyside’,” he explains.   It's clear Gibson, who has been involved in the project since the start, has genuine affection for the whiskies and the stories each one has to tell. He and the team are custodians of historical artefacts that the Gordon family have not parted with for the best part of a century.  “The First Drop”, for example, is named as such because it is the first liquid to run from the stills at the Gordon family’s Girvan grain distillery on Christmas day in 1964. This is the first and last time it can be purchased. “There's a real emotional tie from the family to these whiskies,” Gibson explains. “For the current family members, it's their dad who laid down these whiskies and he's not around anymore.  “I think it's actually quite difficult for the family to let some of these whiskies go, even though there's a begrudging acceptance that they can't drink such quantities and it was time they cut the cord and let these whiskies go out into the world.”  “There's a general principle that we're following where the whisky is ready to go when it's ready,” Gibson explains, “so we're not chasing down a 60-year-old age statement just so that we can put a big 60 on the bottle.”   It has been a pleasant surprise for all those involved to witness the reception the House of Hazelwood whiskies have received from an occasionally prickly and vocal audience.    “Sunshine on Speyside had an amazing response and it's one of the least expensive whiskies within our range,” Gibson says delightedly.   “It was selected because of its character and its flavour, and named because it has this amazing mango/ pineapple popsicle fruit character that transports you to sunshine and the Caribbean. It's one of those ones where everyone instantly agreed that it had to go into the first collection.   “I thought that everyone would be drawn to the oldest whisky at tastings but actually, this whisky captured the imagination of a lot of the writers and the trade.”   It’s hard to emphasise quite how unusual these whiskies are, as most releases – old or new – are described in hyperbolic terms.   “Blended at Birth”, which was released as part of the first collection, is a blend of malt and grain whisky that was married and matured as new-make spirit. Today, it is against the Scotch Whisky Regulations’ technical file to produce a whisky in this way, as you now have to age the malt and grain whisky components for a minimum of three years separately before blending them, so any liquids of this ilk on the market are painfully scarce.   “Unusual” and “esoteric” aren’t always necessarily loaded with positive connotations – you might take a sip of said liquid, politely smile and then return to something slightly less unusual and more palatable – but these whiskies have incredible balance and depth of flavour, in part because they are blends and not single malt whiskies.    “These old grains in particular are just unbelievable in terms of the flavour,” Gibson says with unfettered joy. “At a younger age, grain whisky is quite neutral in character but once you're past 30 years, if it's aged well, grain whisky has a luscious, delicious quality which adds so much to the final profile of the Scotch.    “The variation in style is enormous,” he continues. “I thought I understood old grain whisky but on exploring the inventory further you see these amazing grains that you didn't really know you could get.”   These whiskies wouldn’t have existed if it wasn’t for the foresight of the Gordon family  – and two brothers, in particular, who changed the company’s stars during the mid-20th century. The young Charles and Sandy Gordon brought much-needed vim and vigour to what could be a bit of a staid industry in the late 1950s. The pair famously refused to kowtow to demands from their grain whisky supplier – instead pulling the contract and setting up their own grain distillery, Girvan, in the 1960s. Charles – or Charlie as he was known – even forwent the comfort of his own home and instead lived in a caravan on-site during the build, riding a bicycle to stealthily check on the workers’ progress. His unconventional methods clearly paid off as the sizeable distillery (which still stands today) was built in a record nine-month period.  During their tenure, the duo also interrogated every aspect of whisky-making from distillation to maturation, resulting in the bold decision to employ an on-site coppersmith and cooper – which are still in situ at many of the William Grant distilleries today – to give the family more control. They were a formidable pair and the business arguably wouldn’t have survived some of the challenging periods in Scotch whisky’s history had it not been for their fortitude.     “There's something about family ownership that means you have a bit more luxury to maybe indulge some of your creative whims,” Gibson says with a wry smile. “This independence enabled them to explore ideas that might have been hard for others to justify to their board of shareholders.”  When other producers would have been forced to make very difficult decisions in order to survive those darker years, the larger, independent William Grant would have been slightly more insulated. Out of curiosity alone, they would have been able to hold on to barrels of maturing liquid and see how they developed over time.  These are the barrels that the House of Hazelwood team – and by extension us – now have access to. Each one has an incredible story – and an even better depth of flavour. With eight releases each year as a minimum – and the suggestion of some partnership releases to come as well – there is an audience, who count the great and the good among their numbers, desperate to venture into this unexplored and curious realm of blended Scotch whisky.  Explore all current listings of House of Hazelwood, browse all whisky or read more Editorial

Old, low-yielding vines. I’ve written that phrase more times than I’d like to confess. But how much does it really mean when it comes to the quality of the wine in your glass? The 2023 vintage in Burgundy (read our full vintage report here) produced generous yields. In farming terms, that’s a good thing: a plentiful crop that restocks the cellars (and coffers). But the sheer volume of fruit (“a wall of grapes”, as Bouchard’s winemaker Frédéric Weber told us) posed its own challenge – and much of our time in the region’s cellars this year was spent diving into how they managed, or controlled, the yield. It seemed fitting, therefore, to address the topic in greater detail.  In the Old World, appellation rules will limit yields, with the yield generally decreasing as you move up the appellation system (see below a table detailing the maximum yields for Burgundy, for example). Of course, this indicates a relationship between yield and quality, implying less is better – and there is no doubt that excessive yields don’t produce fine wine. But how low is too low? There is a fashion for prizing vines that barely manage to ripen a bunch or two, but do they really make better wine than those producing a decent crop? Beyond our obsession with rarity, what are the consequences of less fruit per vine – and therefore, what does more entail? A note on measuring yield Before we get into the weeds of the matter, let’s address how we talk about yield. In the Old World, the most common measurement of yield is hectolitres per hectare (hl/ha), measuring the volume of juice or wine per hectare of vineyard area. In Champagne the standard measure is kilos per hectare and in Italy you may see reference to quintales per hectare (qt/ha or q/ha, with one quintal translating to 100kg), while in the US, producers are more likely to use tons per acre. We’ll dive further into the many variables here, but it’s worth highlighting that vine density isn’t taken into account by any of these measurements. Although a higher number of vines per hectare will generally mean a higher yield across the vineyard, the increased competition will also likely reduce the yield per vine. For this article, we have spoken to producers from a range of regions, but do note that yields are not comparable between varieties or region. Climate – with heat, sunlight and water availability, as well as the varying size of berries and clusters of any given variety, mean that there is no number that can be deemed a global average when it comes to yield. (Do look at this table compiled by the Wine Advocate’s William Kelley, comparing vine density, cluster weight and juice yields for various classic fine wine regions, to give you an idea of the differences between regions.) Given this, “high” and “low” yields aren’t equated to specific numbers here, but the concept discussed more broadly – and arguably more relevantly for those of us drinking wine rather than making it. Bearing all of this in mind, extremely approximate conversions can be made as follows: one tonne per hectare is approximately 7hl/ha, while one ton per acre is around 17.5hl/ha (Oxford Companion to Wine). Yields: how low is too low? “It’s not extreme mythology: low yields produce better quality,” Cerbaiona’s Matthew Fioretti tells me; for him, high yields risk dilution and sanitary problems – and at excessive levels, that is certainly true. But, as Myriad’s Mike Smith told me, the relationship is “not linear”. Mike Dunn (Dunn Vineyards) generally has low yields, but that’s not necessarily about concentration, he explains: it’s simply about how much they can ripen before winter hits. Up on Napa’s Howell Mountain, their poor soils and farming (avoiding irrigation and fertilisation where they can) naturally produce lower yields. He recently changed some of their Cabernet Sauvignon to cane (rather than cordon) pruning and, although they’re getting more fruit off the same vines, there’s been no loss in quality. “It’s all relative,” says Ivan Massonnat at Belargus in Anjou. He points to Saumur with its limestone soils, where producers can crop 45-50hl/ha without a problem, but on the schist soils that lie beneath his vineyards: “Forget about doing much more than 30-35hl/ha,” he says. And even that has proven challenging for him. In the seven vintages he’s produced at the estate, only two have come close to 30hl/ha, with the average around 15hl/ha, simply due to the challenges of each vintage. He’d have loved to crop more – but nature had other ideas, and vignerons have to adapt to the vintage. Massonnat explains how if you farm to produce yields that are overly low, you can end up with fruit that has high technical, or sugar, maturity, but isn’t yet phenolically ripe – leading to unbalanced wines. Smith echoes this, talking specifically about Beckstoffer Dr Crane, one of Napa’s legendary vineyards, which he finds likes to produce more – around five tons an acre (versus four in most of the vineyards he works with). He sees producers cropping to just three tons per acre there, and in warm vintages the fruit ripens too quickly for the phenolics to catch up. Philippe Bascaules – who was first appointed Estate Director at Ch. Margaux in 1990 – offers an interesting perspective, arguing that there’s no direct relationship between yield and quality. In Bordeaux in the 1970s, he tells me, yields were consistently low – 25-30hl/ha, with wines that were inconsistent. As the wines became more popular, with demand from the US in particular for the 1982 vintage, producers started aiming for significantly higher yields and chaptalizing much more. Soon, average yields had doubled to 50-60hl/ha – a level that was unsustainable, especially in challenging vintages such as 1992, ’93 and ’94. Gradually they implemented changes, introducing green-harvesting (in 1986 at Ch. Margaux) and reducing fertilisation levels in the 1990s. Today, he and his team aim for around 45hl/ha, “a good production” in his mind – but a level which also offers insurance against inclement conditions. Lowering yields is something that, for him, has brought greater consistency to both the estate and region across vintages – ensuring they can ripen the crop each year. Deliberately reducing the yield beyond this, however, wouldn’t offer any serious benefit, he says. Similarly, across the Durantou family’s estates on the Right Bank, including Ch. l’Eglise-Clinet, Noëmie Durantou Reilhac targets a yield of circa 42hl/ha. “The vine wants to produce fruit,” she says, “so if the yield is really, really low, something went wrong.” For her, it’s the balance that matters most. With very high yields, the resulting wines will lack concentration (“You cannot make in tanks what nature hasn’t done before,” she says), but equally if the berries are so small that there is barely any juice, you’ll have little but tannins left to work with. And, while hail or frost will reduce your yield, they won’t result in greater concentration. “I think it just comes down to stress,” Dunn tells me. And that’s a common thread for several producers, arguing that vines need to struggle to produce quality. As Sébastien le Golvet – of Champagne Henri Giraud, who works with the poor soils of Aÿ – says, “genii are born of suffering”. Suffering doesn’t always mean lower yields, however: arguably, Dunn says, in high-vigour sites, keeping higher yields will help increase stress, pushing the vine to work harder – and therefore produce higher quality. Elements impacting yield While it’s impossible for us to address every factor that influences yield, it’s worth – relatively briefly – highlighting a few additional influences beyond site (with poorer or richer soils), variety and vintage: Trellising: Trellising – the shape in which a vine is trained – can be used to control yield. At Cerbaiona, Fioretti emphasises how using alberello or bush vines is key to helping contain Sangiovese’s natural vigour. At Tiberio, Cristiana Tiberio’s oldest vines are pergola-trained, with a traditional Abruzzese system that encourages competition but also increases the canopy to aid photosynthesis and ripening. Vine material/rootstock: The material used in a vineyard is integral (as with Quinta do Noval’s Nacional vineyard, see below). Mike Dunn, for example, mentioned how one of his older vineyards was planted on St George rootstock, known for shatter and therefore limiting yields even further. Jean-Marie Fourrier (Domaine Fourrier) argues that the use of selected clones, rather than massal selection, has resulted in higher yields and the need to green harvest, something that he never does – aided further by the age of his vines (see below for more on this). Vine age: There’s no doubt that the element of vine age is conflated with yields and quality, with older vines often producing better fruit – but less of it. As Mike Dunn told me, the wines from his oldest vines are “more intriguing”, but at some point economics comes into play, and the level of production is financially unsustainable. It’s another non-linear relationship, however, as Durantou Reilhac explains: “Some 70-year-old grandmas can run and dance, and others are weaker.” Although most old vines will produce less fruit, she finds it’s far from uniform in her vineyards – and sometimes there will be young vines that produce less. Virus and millerandage: Virused vines will produce lower yields, and as with old vines, will reach a point where they are unsustainable. While on the surface virus is negative, certain producers do value the reduction in yield or slower ripening that is a result of disease – South Africa’s Hamilton Russell being one (with leafroll virus). Quinta do Noval persists with its own-rooted Nacional vineyard, suffering from phylloxera, with the vines slowly dying and yielding tiny volumes, to produce a particularly special and rare Vintage Port. Similarly, millerandage is a condition most commonly a consequence of poor weather at fruit-set, producing grape clusters with unevenly sized grapes, combining larger and smaller (or shot) berries – sometimes referenced as hen-and-chick. While this reduces yield, the phenomenon is sometimes valued for giving increased concentration to wine. Indeed, some particular clones – such as the Mendoza, Wente or Gingin clones of Chardonnay – are valued for their bunches with hen-and-chicks, and Bret Brothers, for example, even makes a special Cuvée Millerandée – with millerandée Chardonnay – from Les Quarts (a Pouilly-Vinzelles site recently awarded Premier Cru status). Cover crops: At Henri Giraud, Sébastien le Golvet feels that cover crops are essential to the quality of their fruit – and the yield. Sewn just before harvest, the cover crops provide competition up until flowering when they roll the grass mix, creating a bed that holds water and offers nitrogen to the soils, acting as a natural fertiliser – in a way both moderating then fuelling the vines’ growth. This is one hint at the extent to which the type of soils and level of organic matter, not to mention water availability, dictated by site and the farming methods, are all key. The previous vintage: There are two theories at play here. Firstly, conditions during what is known as the initiation phase of the vine cycle, which takes place alongside flowering, will dictate the yield of the following vintage. In 2023 in Burgundy for example, one of the factors in yield was that the spring of 2022 offered perfect conditions, laying the groundwork for 2023’s plentiful crop. As Sébastien le Golvet also explained, however, a large crop in one vintage can tire the vines, meaning they have less to give the following year. How wine producers manage yield The vine naturally wants to reproduce, to grow, ripen fruit and spread its seeds. Vignerons are tasked with taming the plant to focus its energies to develop fruit of concentration and complexity that will make fine wine. This is done in many ways, some of which include: Pruning: The first stage to set up the yield in an existing vineyard is pruning, leaving the appropriate number of buds per vine for the season ahead. The timing of this varies according to the producer, from December through to March, with later pruning helping delay the vine cycle, which is sometimes desirable. Alvina Pernot, for example, specifically pruned her vines shortly (ie to offer a lower crop) in 2023 to help the vines recover from the relatively high-yielding 2022 vintage. Lalou Bize-Leroy famously works with very low yields, and emphasises how important pruning is in this (Domaine Leroy harvested just under 30hl/ha in 2023, its highest ever yield – a number which would still be low by many producers’ standards). De-budding or suckering: In spring, producers will de-bud or sucker the vines, removing lateral shoots and providing further control of the potential yield, as well as the spacing and position of the crop. In 2023 in Burgundy, many producers emphasised how important this was. Hugues Pavelot described it as “drastic”, while Philippe Jouan passed through his vines twice. At Bouchard, Frédéric Weber explained how some of the buds produced two or three bunches in 2023 (rather than the normal one), meaning that even with extensive de-budding yields were very high. Green harvesting: Green-harvesting is the most discussed method of yield control, and one that divides producers. We spoke to several Burgundian vignerons who avoid it (Dominique Lafon, Jacques Devauges at Domaine des Lambrays, Philippe Jouan and Jean-Marie Fourrier, to name a few) – some of whom felt that they had no choice but to use the method in 2023, despite their best efforts. The reason against green-harvesting is that the vine will try to compensate, and that it can be avoided with managing the vineyard in other ways. That said, there are many top-tier producers that green-harvest, and feel it is key to the quality they produce (Ch. Margaux, Eglise-Clinet, Georges Noëllat and Olivier Bernstein, to name a few). And it’s not a decision that any take lightly, well aware that they are literally throwing away potential income. At Cerbaiona, Fioretti compares the vines to runners or cyclists – needing to carry as little weight as possible to get over the finish line. With Sangiovese, he finds it’s unavoidable, especially with the presence of “wings” or “shoulders” (smaller separate clusters that sit on the shoulder of the main bunch). The timing is key, and many producers emphasise the importance of green-harvesting early in the season. For Noëmie Durantou Reilhac, she aims to have this done prior to véraison to avoid twisting the stems (which would impact sap flow) and damaging the skins of the remaining bunches. She’ll do a final pass through her vineyards just before harvest, but this is a method of sorting rather than impacting the ripeness of the grapes on the vine. “There’s a certain point where you can reduce fruit, say a month away from picking, but it won’t do anything,” says Myriad’s Mike Smith. Like many producers, he favours green-harvesting mid-véraison to drop anything that is behind, helping even the ripeness of the crop – as Bascaules does at Ch. Margaux. In 2023, several Burgundy producers highlighted having to do multiple passes to reduce the crop – doing what was sometimes referred to as a “pink” or “blue” harvest on top of a green harvest. Canopy management: A vine’s leaves are its engine – responsible for photosynthesis. The larger the canopy, the larger the engine, therefore trimming the vine’s canopy can help lower its vigour, while keeping a larger leaf area can help encourage vigour. This needs to be considered alongside airflow (to avoid disease pressure) and shading of the bunches (which could delay ripening). If the canopy isn’t balanced with the volume of fruit, it can also negatively impact fruit composition – especially the acid make-up and development of colour and phenolics. Ivan Massonnat (Belargus) explained that in 2022 and 2023, for example, he used a high trellis, allowing a larger leaf area, to capture maximum light and photosynthesis to fuel the vines; but in 2022 he did the opposite, wanting to reduce the size of the “sugar machine”. It has, he notes, become common for large canopies to be used alongside low yields, especially by producers in Burgundy, something he feels has gone too far at certain addresses: “You can kill a wine with concentration,” he says. Some argue that trimming the canopy can encourage it to grow further, while others want to retain a large canopy to encourage root growth (Olivier Lamy feels that the vine has the same amount of growth above and below ground, therefore wanting to retain his canopy to the roots to drive deep into the soil). Lamy is one of a cohort of producers using “tressage”, or braiding, to tame the canopy – a technique pioneered by Lalou Bize-Leroy. For her the aim is to avoid cutting the apex (or growing tip) which would otherwise encourage the growth of lateral shoots. Producers such as Charles Lachaux have taken this even further, training vines to a single stake (more common on the steep slopes of Priorat, Côte-Rôtie or the Mosel) and weaving the shoots into distinctive arches.  The relationship between yield and quality is undoubtedly a tricky one – and one that every producer I spoke to feels is deeply complex. We couldn’t touch on everything here (the tiny yields for botrytised sweet wines, for example, or typically higher yields used for sparkling wine), but there’s plenty to consider. While it remains clear that excessive yields can produce dilute wines, with so many variables play, it’s also clear that less isn’t always better. Read more Editorial

Yield and quality: is less really more?

Dalmore, Mortlach and Macallan fetch tens of thousands of pounds at auction today – but they likely wouldn’t exist if it wasn’t for an independent bottler. In times of great economic hardship, Gordon & MacPhail provided cash-strapped distilleries with much-needed capital when they secured new-make spirit to mature and bottle as a single malt, rather than a blend. “The world was so focused on blends in the 1970s that to get the financial return on the malts was really challenging,” Gordon & MacPhail’s Director of Prestige Stephen Rankin says. To put that into perspective, a bottle of 35-year-old Macallan from 1937 that would fetch approximately £32,000 in today’s market would sell for a mere £4.54 then. A top-end blend might sell for £2. Rankin says if it wasn’t for his forebears’ patience and foresight, 50-, 60-, and 70-year-old bottlings wouldn’t be available today. “It’s not just matching spirit with oak,” he explains. “It’s actually matching the spirit with the oak and then time and the patience.”   The Gordon & MacPhail name has endured where countless others have not. Today, the fourth generation can pull out samples dating back nine decades from more than 100 distilleries. “It’s that lineage that stands us apart,” Rankin says. “As a company we have had this incredible respect for whisky and depth of relationships forged from 1895.”   “Business was done on the strength of a handshake when my father started the company in the 1940s,” Fred Hamilton Laing – Douglas Laing & Co Chairman and second-generation family member – says. “And so many of our filling programmes still continue today because there was a trust given and a confidence that there would be no abuse of the stock.” If it wasn’t for the “fairly substantial” stocks Laing’s father had built up since the 1950s then the Scottish independent blenders and bottlers might not have survived the 1990s financial crash in Asia Pacific. “All of a sudden our blended business was made very difficult to continue. We were constantly adding to our stocks of grain and malt whisky for these blends, so it was a survival instinct that took us into the single cask business in the year 2000.” This business proved to be “very good” and steadied the ship. Laing says it was with great delight the company was able to come back into the blending business with Big Peat in 2009, much to the dismay of the “crusty old men in the industry”. This launch, looking at younger, slightly more rebellious whisky consumers heralded a new era for the company and brought them full circle. It was the filling programme’s breadth of stock and the relationships with the distilleries that allowed Douglas Laing to carry out the same process for Big Peat and Scallywag into the Scottish Highlands for Timorous Beastie, into the Lowlands with the Epicurean, into the Campbeltown area with the Gauldrons, onto the Island distilleries with Rock Island and introduce the Remarkable Regional Malts. “It’s a busy game,” Laing adds.  Fledgling in comparison, That Boutique-y Whisky Company stormed onto the independent bottling scene in 2012 with their 50cl illustrated bottles. “We are all about throwing fun back into whisky,” Head of Whisky Sam Simmons says. “We take the whisky very seriously, but we don’t take ourselves seriously.” The goal here is simple: curate delicious whiskies you would never see from an official bottling. This disruptive attitude has led to a cult-like following which Simmons readily acknowledges “doesn’t speak to everybody”. The Boutique-y whiskies might originate from around the world, but they are all bottled in the Scottish tradition – bought direct from the distiller or from brokers and other independent bottlers. The retail price is always calculated from the cost of the liquid rather than market value or cost. “The kind of whiskies we want to bottle may not be delicious to everybody, but they are the kind of whiskies that make you say: you got to try this,” Simmons adds. When it comes to bottling exquisite liquids, few ventures are as compelling as “curators of the most remarkable spirits”, The Last Drop Distillers. “I really love the word remarkable,” Managing Director Rebecca Jago says with a smile. “Because it is not saying it is the oldest or the best even, but that it is intrinsically delicious. If I gave you a glass of something from The Last Drop, I would want you to find it as delightful as someone who has been nosing spirits for 50 years.” The company started by Rebecca’s father Tom and his long-term friend James Espey OBE in 2008 is somewhat unique in that it crosses category. The two drinks industry icons initially set out to bottle single malts, but that all changed when they tasted a certain 47-year-old blended Scotch. From that day onwards, the two men – who had previously developed the likes of Johnnie Walker Blue Label and Chivas 18 – broadened their brief to seek out exceptional old parcels of any amazing spirit. By the time the company was sold to Sazerac in 2016, The Last Drop had released seven remarkable liquids and both Espey and Jago’s daughters (Beanie Geraedts-Espey and Rebecca Jago) had joined the business. In addition to being a source of great pride for the two founders, the acquisition also brought new freedoms and opportunities for the team. The US drinks group backing enabled The Last Drop to source stock for immediate release, granted them a greater ability to lay down stock and create their own libraries of future stock, and gave them the opportunity to venture into liquid creation. “I think finding treasure is not just about uncovering it,” Jago says. “It would be disingenuous to suggest that we’re Indiana Jones in Scotland, going and hunting out that barrel that is hidden at the back of the cellar because it is not,” Jago says. As romantic as the image might be, every single barrel of Scotch whisky of any age, of any sort, is known about by HMRC.  “We can talk about some of the lovely discoveries that we have genuinely been party to,” Jago adds. “Going back to the very first release of three unassuming barrels of an old blend. The treasure in that was the liquid inside. It had perhaps been discounted or forgotten about.” Or the “genuine discovery” of a Cognac barrel that had been lying untouched in an outhouse for over 70 years that was happened upon by a family member doing renovation work at the distillery. “I think that is the sort of ultimate Indiana Jones story,” Jago adds, “not by us, but we were fortunate enough to be there and I suppose our story of making the liquid the hero is sufficiently compelling that they are prepared to let us put it in a bottle.” All four bottlers, whether in their infancy or maturity, are bound by a sense of honour and wanting to do right by the liquid. And everyone benefits.   Browse all Scotch whisky or read more Editorial

Message in a bottle

When it comes to whisky, the conversation has long been dominated by maturation – on how long the liquid spends slumbering in which cask, on how big the cask is and what it held before, whether a Sherry butt, wine barrique, first-fill Bourbon barrel or the fashionable mizunara. Recently, there’s been an increased focus on the base product, with producers such as Waterford’s Mark Reynier championing single-site, single-barley, terroir-driven whiskies (and rums, with his Renegade project). But, somehow, there’s a tendency to skip on by the magic that happens in between: distillation.  While grain whisky is column distilled, malt whisky is almost exclusively distilled in copper pot stills – indeed, it’s a legal requisite for Scotch whisky. Crafting these copper beauties is an art – and one that depends on a handful of specialists. Kentucky has Vendome, Germany has Kothe and CARL, Italy has Frilli and Scotland has Forsyths. The equipment these coppersmiths produce lays the foundation the DNA of its new-make.  To the untrained eye, these onion-shaped pieces of kit look almost identical, but the size and shape is distinct to each distillery – defining its style. As distilleries expand and increase production, they don’t buy a bigger still – but commission exact replicas of their existing still(s), with every dent and dimple carefully recreated. Macallan, famously, replaced all its stills when building its new state-of-the-art distillery in 2018, asking Forsyths to create 36 stills that were identical to those it had previously used.  Although there have been attempts to use other metals, copper has long been favoured for distilling – originally for its pliability, making it easy to work and shape. But by the early 20th century, it was apparent that copper had other benefits – stripping the spirit of impurities. As the vapour rises through the still, it reacts with the copper, capturing sulphur, cyanides, carbonates and acids, meaning the liquid that is eventually collected is purer. Coppersmiths play on this purifying effect to create a range of stills, for the longer the vapour spends in contact with the copper, the lighter the spirit you’ll produce. Take Glenmorangie’s tall, 17-feet-high stills which produce a very light spirit, and compare them to the small, squat stills and typically heavy spirit of the Macallan. Of course it’s not quite as simple as that. As well as the ratio of copper to liquid, the speed of distillation, the shape of the still, the size of the neck, the level of reflux, the angle of the lyne arm and venting of stills all have an impact.  Rothes-based Forsyths has been hammering copper into shape for Scotland’s leading distillers for over 150 years. Richard Forsyth OBE (who has now passed management of the business to his son, Richard Jr) was the third generation of his family to run the coppersmiths. The frank, self-effacing Scot remembers working in his father’s workshop aged 15, “I knew this is what I wanted to do… I found it fascinating.” And after 55 years, his eye still twinkles when he talks about the arch of a still’s swan neck, the art of wielding a planishing hammer and the characters that make the industry so interesting.   He joined the family business in 1967 – at what happened to be a pivotal moment for the industry. During the Second World War, the whisky business ground to a halt – and with it the need for stills. In the 1950s and ’60s, however, the industry grew rapidly – too rapidly, it turned out. What was a golden era turned into a whisky lake, with many distilleries soon mothballed. Forsyths – for whom 99% of its business was servicing the whisky industry – had to find something else to pay the bills, and it was up to Richard to find that something else. They branched out first into paper, then stainless steel and – by the late 1990s – oil and gas. Although coppersmithing remained the foundation and heart of the business, these other disciplines became the main money-makers until the early 2010s, when whisky’s current boomtime set in. Today, Forsyths maintains over half of the pot stills in Scotland. For a wash still (distilleries that double-distil have wash and spirits stills, first distilling the wash into “low wines” and then distilling the “low wines” into new-make spirit), the head, neck and condenser wears out in eight to 10 years, while the pot itself may last 25. Add to that developing new stills for the thriving industry – as well as their expansion into rum, Bourbon and tequila – and the company’s not short of work.   Although there is clear resistance to change with an industry that is entrenched in tradition, things have shifted, slowly but surely, over the years. And there have been two significant changes over the last century that have transformed the Scotch whisky world: the firing of stills and the nature of condensers.  When shell-and-tube condensers were invented in the 1880s, as an alternative to old-fashioned worm tubs, it took time for producers to be persuaded. Although shell-and-tube condensers are significantly more efficient and take up much less space, they are completely different – with the copper surface area at least 20 times larger, something which has a key impact on the spirit. To this day some producers (15 to be exact – including Craigellachie, Mortlach, Glen Elgin and Springbank, the latter only for their wash still) retain their worm tubs, valuing the heavier, richer, more complex (and in some instances, even meaty, savoury) spirit character.   Traditionally stills were direct-fired – heated by flames fed by peat, coal or gas. “It’s dirty, messy, difficult to handle – and to control,” Forsyth tells me. A push for safety and efficiency saw producers switch to using steam in the 1970s. But some argue that this shift wasn’t for the better. Fire created a less consistent heat, with hot spots that would burn the wash and promote Maillard reactions (the same reaction that takes place when you brown meat, or during the bottle-ageing of Champagne or other traditional-method sparkling wine) – adding nutty, roasted notes that build complexity, or so proponents would argue. Glenfarclas is known for having briefly dallied with steam before returning to direct-firing, along with the likes of Macallan, Glenfiddich and Springbank.  As the whiskies of this pre-modernisation era – Scotch’s so-called “golden age” – become increasingly coveted, distilleries (both new and old) are looking to recreate these practices. Along with traditional floor maltings, producers like Glen Garioch (owned by Suntory) and Dunphail are investing in direct-firing. (Although, with worm tubs no longer produced, new distilleries have little choice regarding shell-and-tube condensers.)  However they are fired, given their custom nature, copper pot stills don’t come cheap. Much of the work continues to be done by hand, hammering to strengthen and finish the copper. Stills can range from 5,000 to 50,000 litres in capacity, but an average 15,000-litre still and its condenser will require between 1,800 and 2,000 manhours, and set you back around £250,000. And that price has only increased recently, thanks to rising energy and material costs – with a copper shortage proving challenging for Forsyths, a business that is the UK’s second-biggest buyer of the metal.  With the distinct nature of stills and their impact on spirit, plenty of new producers will ask for copies of a particular distillery’s stills – wishing to emanate their style of spirit. Forsyth tells me how one Japanese customer requested a pair each of Macallan, Glenlivet and Glenrothes stills. While of course there are many problems with this imitation game, there’s also no guarantee – as Forsyth tells me – that the same equipment will have the same results, especially when not run with the same wash, in the same way, by the same people. And, of course, a company like Forsyths isn’t going to give away Macallan’s proprietary designs, for example. As such, they’ll recreate something similar, but ensure it’s tweaked so no two distilleries have exactly the same design.   But how much impact do stills really have on the final spirit? Despite his half-century in the trade, Forsyth is quick to suggest, “I don’t think a lowly coppersmith can talk too much about that.” He’s clear that you need good equipment to make good spirit, but it’s one factor in amongst everything else – the barley, water and fermentation times, for example. And how a still is used is as important as its shape or size, with both the speed of distillation and the all-important cuts – dividing the heart from the foreshots and feints. Forsyth firmly believes that good wood is “the single biggest effect in a bottle eight, 10 or 12 years later”. There’s little use having a good base spirit if it’s ruined by a decade in bad oak – but good oak also can’t salvage bad spirit.  Forsyth has seen it all during his 55 years in the whisky business – and has been forced to be as malleable as the metal his family has worked for generations to survive the booms and busts. Despite the challenges, the coppersmith is as enchanted by his trade as when he first picked up a hammer in his father’s workshop. The industry will doubtless continue to ebb and flow, but with a spirit that takes decades to produce, the pace of change is reassuringly gentle. “It almost goes as slow as the running of the spirit,” Forsyth says whimsically. The still room remains the beating heart of distilleries – the basis of a producer’s fingerprint, all thanks to the careful hammering of the artful coppersmith.  Browse all current Scotch whisky listings or read more about spirits  

There’s something romantic about the bulbous sheen of a copper pot still. These behemoths glimmer with the promise of fine spirit – but it’s rare that we talk about what happens within. Sophie Thorpe sat down with Richard Forsyth OBE of Scotland’s leading coppersmiths, Forsyths, to find out more
