Anyone who’s had the misfortune of tasting a de-alcoholised version knows that alcohol is key to wine. Take it away and it leaves a gaping void in the glass – stripping the liquid of body and flavour. Those attempting to craft alcohol-free alternatives look to make up for its absence with sugar or flavourings, but the results don’t come close to the real thing. And of course the very fermentation process is key to complexity – there’s a reason we aren’t collecting single-site examples of even the finest raw grape juice. But alcohol’s a hot topic – and not just because of any health considerations. Trends and shifts in climate have seen the average ABV (alcohol by volume) inch upwards. Indeed, a report last year from Liv-ex suggested the average alcohol level has leapt almost an entire 1% for both California and Bordeaux since the 1990s. While once 14 or 14.5% might have been the purview only of the New World, it’s rapidly become the norm in Bordeaux. Rising temperatures are one element, as indeed is technology and know-how – harvesting cleaner, riper fruit and more efficient winemaking. Then, of course, there’s the fashion factor – the pendulum swing, arguably driven by Robert Parker, for bold, ripe, sweet and inevitably high-alcohol wines. “He loved that weight, that impression of sweetness,” Paul Hobbs tells me. “We jumped on the wagon – but we didn’t know what we were jumping on.” A cult name, Hobbs crafts some of Napa’s highest-scoring and most expensive Cabernets; indeed, Parker named him his Wine Personality of the Year twice. Born in New York State, the Davis-trained winemaker founded his namesake estate in 1991. He’d started his career at Robert Mondavi (arriving in 1977), working at Opus One and Simi before setting up on his own, with a flurry of personal projects and list of consultancies that has grown ever since. He openly admits that he got caught up in “Parkerisation”, crafting big, bold wines – no great surprise given the scores, and sales, that followed for those who did. But he’s been pulling back in recent years, and has never quite fit the cookie-cutout for the cult Cabernet crew. Ever since he first started making his own wines in the 1990s, he’s championed native yeasts (relatively radical at the time), and no fining or filtering. While he embraces oak, he’s always been aware that it’s the quality of fruit in the vineyard, preserved by operating a flawlessly clean winery, that is key to producing fine wine. Make no mistake that Hobbs makes rich, plush wines – and the alcohol levels certainly don’t sit at 12.5% – but for him there is much more to alcohol than one number. “I didn’t give much thought to it in the beginning,” Hobbs says. “And there wasn’t really much reason to.” When he was at Mondavi, the wines tended to sit at 13.5% – but then they started to go up. “There was a time when 16% was normal,” he confesses with some amazement. “Some of these wines were difficult. They didn’t age. They would get tired,” Hobbs says. “But all that took us time to learn – no one had ever been in that domain before.” He notes that there was “a backlash” in the British press against wines that didn’t please the palates of “the Hugh Johnsons, the Jancis Robinsons and Anthony Roses”; a response he clearly feels was a little unjust. “It’s far more complex than a simple number,” he says. “15 isn’t always 15.” And it’s true – alcohol doesn’t feel the same. How many times have you looked at the label of a wine and been surprised – either for better or worse? Alcohol is one element working in tandem with a wine’s body, concentration and flavour complexity – and there’s no easy figure to tell you how it integrates with these other components. But there’s another key reason why the same alcohol level can seem so different: the nature of the alcohol. The main alcohol in wine is ethanol (a molecule with two carbons), however fermentation produces other types of alcohols – specifically superior or higher alcohols. Often known as fusel oils – from a German term “Fusel” which is colloquial for low-quality booze – these alcohols have three to six carbons in their molecular form and are significantly more viscous (hence “oils”).  While ethanol is pure and relatively neutral, these heavier superior alcohols can – in low volumes – bring flavour, texture and interest. “It’s what makes something more than vodka,” Hobbs explains. Hexanols can add herbaceous aromas; 2-phenylethanol gives a rose-like scent. But they’re also associated with headaches and hangovers. In the world of spirits, these fusel oils are what runs out of the still last – forming the “tails” of distillation, which are used to varying degrees depending on the type of spirit being produced. “Alcohol is alcohol? Well, yes and no,” says Hobbs. It's high numbers of these superior alcohols, he believes, that can make one 15% wine feel clumsy and lumbering, while another – with lower fusel oil levels – can carry the same ABV with ease. The production of these superior alcohols depends on many things – yeast strain, temperature, oxygen availability and acidity. In general, red grapes produce more of the compounds (which is partly why spirits tend to use white grapes as their base). But Hobbs thinks it ultimately comes back to the vineyard: he’s started noticing that if berries are heat-damaged, they produce more superior alcohols. “Our goal is to keep these superior alcohols as low as possible – and that’s just about harvesting not sun-damaged fruit,” Hobbs explains. Under the warmth of the Californian sun, it’s common to get sun damage early in the season, but shrivelled berries tend to fall off nascent clusters of their own accord; more concerning is fruit that can be damaged internally and then won’t go through véraison, which needs to be sorted out. Late in the season, Hobbs and his team look to walk through the vines and cut off any “shoulders” (the side cluster at the very top of a bunch of grapes) that have been exposed. With global warming, this is an increasing threat – and an element of climate change that is only now being considered. If grapes are sunburnt or shrivelled, they tend to struggle with fermentation, and the stressed yeasts produce more of the superior alcohols. “The wine is going to be fat and heavy on the palate,” says Hobbs. “You can lower the alcohol by adding water – but it doesn’t change its personality.” If the fruit is in good shape – he says – you simply don’t have that issue, even at 15.5%. And those wines, provided they’ve got the requisite balance, age amazingly. Rajat Parr (star sommelier turned winemaker) and Jasmine Hirsch (of Hirsch Vineyards) founded In Pursuit of Balance (IPOB) in 2011 to champion lighter wines that they felt “weren’t chasing after ratings from wine critics”. These “new California” wines (Jon Bonné published his book The New California Wine in 2013) tended to have lower alcohols and less oak – following the swing of the pendulum back the other way; an anti-Parker effort in many ways. I attended the last London IPOB tasting in 2016, catching the crest of the wave as the movement called it quits – feeling they’d achieved their aim of building the reputation of an alternative California. Paul Hobbs arguably sits at the opposite end of the California wine spectrum (“Should all wines be 13.5%?” he says to me, “Why is that the magic number?”) – but philosophically, they’re surprisingly aligned. It’s not about the number, it’s about the balance – and Hobbs, like any posterchild of the new California movement, will tell you that the secret lies in the vineyard. The challenge is to farm and pick the perfect fruit – to find the sweet spot between flavour, sugar and phenolic ripeness. As Hobbs says to me, “That’s the dance between man and nature.” Forget the maths; this is farming. A note on the numbers Strictly speaking, the alcohol level on any label isn’t exactly what’s in the bottle. For wines sold in the EU and UK (both those made here and imported), producers are given 0.5% leeway – meaning that what’s on the bottle is generally reflective of its contents. In the US and Australia, however, wines sold domestically can differ by as much as 1.5% from the label – meaning a wine labelled as 14% could be anything from 12.5 to 15.5%.

The nature of the numbers: Paul Hobbs on alcohol

It’s no secret that Scotch whisky is dominated by two giants – Diageo and Pernod Ricard, who represent 60% of the market, with three other big players taking the next 20%. That leaves a mere 20% for those who have the wallets and mettle to fight over the rest – but that’s an increasing number of people. There are currently over 30 single malt distilleries at some stage of opening.  “I think it’s a bit of a worry to be honest,” Mark Reynier, Renegade Spirits founder and CEO, says. Reynier has been behind three of the most talked-about distillery projects in the past 20 years – the resurrection of Islay powerhouse Bruichladdich in 2000, the renovation of a former Diageo brewery into Irish single malt distillery Waterford in 2015 and the construction of Renegade rum distillery in Grenada from scratch in 2020. All three have a dogged focus on terroir and have not been without their struggles. “Superficially it does look easy - but it sure as hell isn’t,” he says. “With Bruichladdich we almost went bust twice. With the best will in the world and two-distillery experience I got it wrong with Renegade and almost went bust last September.”  In Reynier’s view, many of those opening distilleries are driven by romantic ideas and the desire to make a quick buck – from landowners looking to monetise estates to “crooks” who “promise fortunes to be made”. Few, however, have the knowledge, business nous or money to back up their ambitions.  Wolfcraig – a new distillery in Stirling – is one of the industry’s most interesting projects, largely thanks to the experience of the team involved. While neither of the founders Jamie Lunn or John Moore had worked in whisky before (coming, respectively, from construction and finance), Jamie Lunn’s father is former Whyte & Mackay chairman and chief executive Michael Lunn – and happened to be eager for a new project. It hasn’t been plain sailing though: the team had a false start with an ill-fated attempt to take a controlling stake of an existing distillery. Downhearted but not defeated, they made the decision to go it alone. Moore and Lunn have assembled a first-rate team with over 200 years’ experience. Master Blender Richard Paterson OBE was the most recent addition to the roster – which Jamie Lunn affectionately refers to as “the Harlem globetrotters of whisky” – including Dr Alan Rutherford OBE (former Production Director at Diageo, Master of the Quaich and previous President of the Malt Distillers Association of Scotland), Ian Macmillan (a Master Distiller, also a Master of the Quaich and a member of the Worshipful Company of Distillers) and Iain Lochhead (former UK Bacardi Operations Director, and another Master of the Quaich). But even with a team of such pedigree, it hasn’t been easy. “It was three and a half years of pain,” Moore says. Every decision has been driven by an unwavering mission to produce a truly special liquid, considerable industry experience and business acumen. Stirling, for example, was chosen not just for its infrastructure, but its accessibility – within an hour’s drive of 70% of the Scottish population. The team ensured they were fully funded and have consciously built a brand – and decided on the style of spirit they’ll be making – before physically breaking ground. “Out of all the new whisky distilleries,” Moore says, “very few of them are designing their own unique spirit and they have not put any thought into why they have a particular shape of still.” Wolfcraig, by contrast, is having their still handmade by Forsyths, with a distinctive double-ball design to produce a more muscular, full-bodied spirit. It’s not just new players and mavericks behind the trend though, with some of whisky’s most historic names being given a new lease of life. Halewood International, for example, is bringing malt whisky distilling back to the heart of the Scottish drinks industry in the Port of Leith, Edinburgh, for the first time in 100 years with the John Crabbie Distillery.  Today, the name John Crabbie might be synonymous with ginger wine, but he was an independent bottler, single malt producer and recognised blender in the 19th century. For the team here, creating something new brings great freedom. “One of the key parts of our distillery is its versatility,” Global Dark Spirits Manager Andy Wallace says. “Because of the type of distillery we have, we can change our new make spirit and we can be very adaptable. That flexibility, put in the hands of somebody who knows what they are doing, like our Master Blender Dr Kirstie McCallum – a chemist with an excellent palate – and we’re going to experiment.”   Experimentation with different casks is high on the agenda. In addition to PX and Oloroso casks, the team is looking at how Manzanilla might work and playing around with other wine cask finishes.   Prior to joining Halewood, Wallace spent six years at William Grant & Sons, the home of Balvenie and Glenfiddich since 1887. “They are beautiful, incredible distilleries in a beautiful part of the world,” Wallace says, “but they come with their own inherent limitations… some people will see them as being a bit aspirational and not for them.” In his view, building something from scratch – even with a history like Crabbie’s – means they don’t have to produce a certain type of product. “What we want to do is bring new people into the category and allow people to drink differently,” he explains. Free from the burden of a legacy, a new distillery can be more agile. This can, however, be a catch-22. In a quest to stand apart, rather than play the old boys at their centuries-perfected game, innovation – if not managed in a considered, well-financed, way – can end in tears. “A lot of people have got rather carried away with the romance and [they] don’t really understand the consequences and the costs, and the durability that you need,” Mark Reynier explains.  “And above all you need a unique proposition. Just to be another distillery isn’t enough. The distilling bit is the easy bit. I think this is what’s going to be the downfall for a lot of people. The maturation and the time and cost is the crunch. And then you have got to bring it to market.” Wallace agrees. “You must have a long-term plan for selling your product because you have got a several-year timeline before you can launch anything in the first place,” he says. “One of the big challenges for whisky companies is predicting demand. If you have to predict how much 12-year-old product you’re going to sell on day one, that is a really difficult challenge.”   This was one of the many reasons Wolfcraig was determined to be fully funded from the get-go. “A lot of new whisky distilleries are just living hand-to-mouth and raising money year-on-year and that is emotionally draining,” Moore says. “But, also more importantly, it takes time away from the business when you are constantly fundraising.” It’s no small amount of money required, either. While you might be able to start a gin distillery with £50,000, whisky is a different beast. “Even the small craft distilleries, you’re talking several million pounds to set up,” Moore explains. “Our overall investment will be close on £20million… So, it’s not something you go into lightly.” “Running a distillery is an expensive business,” Reynier adds. “Just when you most need the revenue to get into the market, that is when you are least likely to have it. You are building in a lag period. You have created this brand over a decade, but you don’t actually have enough stock maturing to satisfy the sales that you have created or are creating. So, you have got to plan forward.” Waterford is a distillation of everything Reynier got wrong at Bruichladdich and everything he felt he wasn’t able to do because of a “lack of resource, lack of desire perhaps, tradition getting in the way, and the lack of logistics”. “We had a war chest because we knew that to do it properly, we had to be able to insulate ourselves financially to be able to buy ourselves the time to do it properly, with proper, premium-quality barley, single-farm distillations for uniqueness and for complexity,” Reynier explains. “Practised at Bruichladdich, perfected here.” Ultimately, once you get past the business and branding, it’s the quality of the liquid that will sort the wheat from the chaff. “We need to achieve the same core things any distillery does,” Wallace says. “We want to make genuinely brilliant drams that people will enjoy in years to come.” Browse all Scotch whisky or read more Editorial

Distilling dreams

When visiting the cellars of Domaine Hubert Lamy, you are likely to come out a lot wiser than you were when you went in. Olivier Lamy has been experimenting ever since he joined his father at the domaine in 1995, and he loves to share his findings.  On our last visit we were given two white wines blind and asked to assess them. One thing seemed immediately clear: with its deeper colour and more developed savoury tones, one wine was older than the other. “No” he replied. “They are the same age.” Okay, perhaps the reason for such variation in development is due to the wines coming from two different quality sites – a Grand Cru versus a village wine for instance? “No, it is the same vineyard,” he replied. Perplexed, the only other solution I thought must be his high-density plantings. (Olivier has planted parts of his vineyard three times the density of the norm in Burgundy, with up to 30,000 vines per hectare), the result being smaller, more flavourful berries. Wrong again.   “Wrong experiment,” he smirks, leaving us completely stumped. He presents the two bottles and the answer lies with the capsules. Both wines have the same cork closure but one has the traditional metal capsule seal, the other bottle has been dipped in wax. It is the wax capsule that seems not only younger and fresher, but more texturally complex, yet both the wines are from exactly the same vineyard, with the same vine density and vintage. It is simply the closure that has preserved one wine so much better.   Olivier has been experimenting with closures for years. There have long been concerns about natural cork, with the risk of cork taint top of the list of potential problems, but it was the issue of premature oxidation, particularly with white Burgundy, that led Olivier to investigate whether maybe the problem lay with the closure.  Despite the drop in natural cork’s popularity and their replacement with alternative, “technical” corks and screwcaps, the natural cork still has plenty of advocates, and it remains the most sustainable and natural of solutions for many. A better understanding of the causes of cork taint has vastly improved the natural cork’s reliability and reputation, yet “being a natural product there remain irregularities in the cork,” says Olivier. Natural cork is irregular in structure, therefore allowing different levels of oxygen ingress, meaning that the same wine can mature differently depending on the specific cork, and resulting in bottle variation.  Olivier also believes the irregularities of cork have become worse in recent years due to climate change, with the warmer temperatures resulting in even less consistent cork.  The benefit of the wax capsule, according to Lamy, is that it acts like a “bandage”, offsetting the irregularities of the cork. His grandfather and many other winemakers often used wax capsules for wines destined for their personal cellars; it was the reliable ageing capacity of these wines that prompted his experiments. Trialling the effects of waxed and unwaxed capsules since 2009, he decided to use wax capsules on all his wines in 2016. Over this time, he has experimented with varying diameters and lengths of cork, different treatments, as well as testing plastic, agglomerate, and technical corks before concluding that longer (54mm), technical DIAMs (a natural cork-based agglomerate closure), under wax seal produce the best results and best protect against premature oxidation.  Does this mean we have a definitive answer to the question that has plagued white Burgundy for the last couple of decades regarding premature oxidation? While his experiments certainly seem to imply that the irregularity of natural corks could be one of the biggest culprits and wax capsules one of the most successful solutions, he does not believe it is only the cork which is at fault. “There are two problems,” he says. “Poor-quality corks and the fact that wines are more fragile these days.”  The increased fragility of white Burgundy, Lamy believes, is a modern phenomenon. Climate change produces riper grapes, combine this with too many new barrels, modern presses that are too protective and you have wines that are more susceptible to oxidation. All too aware of this concern, many vignerons, Lamy believes, attempt to overprotect their wines, adding too much anti-oxidative sulphur dioxide (SO2) throughout the winemaking process. Counter-intuitively, this in fact makes the wines more susceptible to oxidation. When wine is made in a more protective environment, the more volatile phenolics remain in the wine, whereas these will drop out of a wine  when it is made oxidatively at the early stages of vinification, resulting in a much more stable wine.   Despite vignerons’ better understanding of the effects protective winemaking has on long-term ageing, these techniques are still used by many because it makes the wines so much more approachable in their youth. Many white wines today are built on developing these youthful aromas at the expense of ageing potential, Lamy argues. This is, he says, is in direct contrast with the past, where wines were built on texture, remaining fairly closed in their youth, with the aromas only developing with age.  There are still many traditional vignerons in Burgundy producing textural white wines built to age – with Lamy (who does not enjoy young, aromatic Burgundy) being one of them. With the warming climate, he has, however, had to adapt his winemaking to protect these more fragile wines. These days he manages the press cycle according to the vintage and allows for more solids when required.  With all the wines now bottled under DIAM and wax capsules, all Lamy can do now is wait. But, if his experiments are anything to go by, the risks of premature oxidation are low. Of course, he’s not sitting back – the dynamic winemaker is looking to experiment even more, pushing the boundaries to produce the best, and most age-worthy, wine possible.
