Peat in whisky is divisive – both in terms of its intense flavour profile, but also its sustainability. It has long been used in Scotch whisky, adding complexity to the region’s spirits, but has – over the last two decades – been thrust into the limelight.  Essentially, peat is baby coal – decomposed organic matter, in particular sphagnum moss, that takes thousands of years to form. Historically, these peatlands – wetlands such as bogs and fens – were used for fuel, especially where other energy sources weren’t readily available. Slabs of peat, cut out of the ground and left to dry, were burnt, valued for their ability to (like coal) smoulder steadily. Peat would have originally been used to heat pot stills, giving off intensely scented smoke that distillers eventually looked to capture.  Today, energy sources are largely more sustainable, and peat is used in significantly smaller volumes in the kilning process. After the barley has been malted, it is kilned (essentially dried). For peated whiskies, this is done (at least in part) over a peat-fed fire, so that the barley picks up the flavours from the smoke. This barley is then milled, mashed, fermented and distilled to produce the whisky, with the peat smoke lending flavours that range from soot, smoke and asphalt to seaweed and iodine.   Peatlands have been put in the spotlight with climate change, given their incredible capacity to hold carbon – and release it. As a NatureScot report (2023) states, “Although peatlands cover less than 3% of the world’s surface, it is estimated that they store double the amount of carbon held in global forest biomass and more than 30% of the total global soil carbon store (Bonn et al., 2016). Peatlands make up some 9.5% of the UK’s land area with an estimated carbon store of over 3,200 million tonnes, of which 1,600 million tonnes are estimated to be in Scotland (Bonn et al., 2016).” But while they have an impressive ability to lock away carbon, once peatlands are damaged they release some of that carbon – and the same report estimates that degraded peatlands account for circa 13% of Scotland’s carbon emissions. (It’s worth noting that the same institution – then known as Scottish National Heritage – came under fire in 2020 for its agreement with Diageo, allowing for unlimited peat extraction on Islay.)  Peat accumulates at a mere 1mm a year, so it’s easy to see why peat extraction is a hot topic. Protecting and restoring Scotland’s peatlands are firmly on the national agenda, and in 2020, the Scottish government announced £20 million earmarked for restoration, with a commitment to invest more than £250 million by 2030. Unsurprisingly, it’s put Scotch whisky’s use of peat under the magnifying glass. In reality, a fraction (just 1%) of Scotland’s peat goes to the spirits industry – with horticulture the main culprit.  As Bruichladdich’s Head Distiller Adam Hannett says, however, it has provided “a great lens to look at what we’re doing with peatlands”. For him, “It’s about responsible extraction.” Bruichladdich’s production director is also looking at restoration projects with local farmers. In 2021, two giants of the industry announced significant projects – one from Diageo’s Johnnie Walker, partnering with the RSPB to repair wetlands, and a more ambitious pledge from Beam Suntory, with its Peatland Water Sanctuary Initiative. The project aims to restore twice the volume that the company harvests for use in whisky production, with $4 million invested by 2040. Some producers – such as Nc’nean – have sworn off peat totally, while others are moderating usage, or looking for alternatives.   In Sweden – where peatlands represent up to 20% of the entire land area, Mackmyra’s Blender Lii Johnson explains how there is strict regulation around their usage. They are one of a growing number of producers looking to use peat as another way to explore their terroir. As few producers malt and kiln their own barley today, often this is shipped from Scotland (in turn adding to distilleries’ carbon footprints). At Mackmyra, they instead use Karinmossen – local peat, harvested around 40km south of the distillery – seasoned with juniper twigs. She estimates they use a mere 0.1% of the peat bog, bringing in around 30 cubic metres per year.  Johnson feels that it is the juniper in the Karinmossen, along with the small twigs they add (picked from the woods around the distillery), which give a light citrus, almost medicinal note to their peated malts. In Seattle, Westland has pioneered using local peat, and a process with a backhoe to keep the bog intact and limit their carbon footprint. Co-Founder and Managing Director Matthew Hofmann feels the local peat brings Mezcal-like aromas to their peated whisky, Solum.   This quest for sustainability, combined with emphasis on the concept of terroir in whisky, has had interesting results at distilleries around the world. In Minnesota, Brother Justus sources peat from the Boreal Forest and has trademarked a cold-peating process to produce more delicate aromas. Tasmanian distillery Lark looks to Browns Marsh for its peat (around one cubic metre a year) and has had the International Mire Conservation Group confirm that it is having zero impact on the marsh. Others are looking to use alternatives – New Zealand’s Thomson Whisky uses manuka, while Archie Rose has looked to Australian hardwoods and, perhaps most distinctively, Iceland’s Eimverk sources sheep dung from local farms in lieu of peat.  As we’ve touched on, however, it’s not just what is used to peat malt – but how it’s used, that impacts the flavour of the final whisky. “Duration, in my opinion, is the key,” says Mackmyra’s Johnson, emphasising that it is how long the barley spends in contact with the peat smoke that influences the level of peatiness, while it is only the type of peat (or peat alternative) that will effect the nature of the peat flavour. She explains how whether the barley is peated pre- or post-break is also important: it’s most common to do pre-break, as if it is done post-break, when the barley is largely dry on the surface, it doesn’t pick up phenols – the compounds that produce peat’s smoky flavours. For Mackmyra’s peated barley, it is kilned for one day with peat and then for a second day just with hot air.  There are other factors too however – with fermentation times and cuts often a focus. While longer ferments are generally thought to engender complexity, shorter ferments preserve phenols. There are three factions to a still run – the foreshots, heart and feints. The foreshots and feints, the liquid that runs off first and last, are generally discarded, and the cuts between these determine the character of the heart. Phenols generally come late in the distillation process, so later cuts can be preferential when looking for peat character. For Mackmyra’s Extra Rok 2.0 – an extra-peated malt, they do shorter ferments and a later cut, to preserve the phenols.   It's become fashionable to talk about “ppm” in peated whisky – parts per million (perhaps familiar to wine lovers as the same term that is used for sulphur levels), to measure the level of total phenolic compounds. It’s perhaps unsurprising that the compounds are the same as those for smoke taint, including guaiacol and 4-methylguaiacol, for example, but while in the world of wine these are avoided, distillers of peated whiskies have competed to produce the spirit with the highest. This race to make the peatiest whisky possible was arguably inspired by Compass Box’s Peat Monster (first produced in 2003), building to and culminating with Bruichladdich’s Octomore 8.3 (released in 2017) – a whisky with a remarkable 309ppm, the highest level measured to date (compare this to the first Octomore release which had 131ppm). In this frenzied period, Ardbeg’s Dr Bill Lumsden even buried a barrel of peated whisky in a peat bog (which was released as an NFT in 2022, Ardbeg Fon Fhòid). But while one number is an easy way for whisky drinkers to grasp how peaty a spirit is, not everyone believes it’s helpful.  “We don’t like to talk about those numbers,” says Johnson. She explains how ppms are somewhat farcical, in her view. When the reading is taken varies from distillery to distillery, and therefore provides something that is almost impossible to compare. While most are taken at the mashbill stage, if you are later blending, it’s an estimate at best. Not only that, but the make-up of the phenolic compounds will influence how peaty one 100ppm whisky is versus another 100ppm whisky. For Mackmyra, their pure peated malt sits at around 300ppm, but the mashbill for their peated and extra peated whiskies are respectively around 70 and 140ppm, Johnson reluctantly tells me. The level of phenols can also vary significantly between batches of barley – and at Mackmyra they aim to combat this by doing one kilning a year, distilling all their peated whisky at once and blending the batches to create a consistent product.  It's almost for this exact reason that Bruichladdich created Octomore, Head Distiller Adam Hannett explains. The project’s numbered releases have significantly different levels of peatiness, and were a project inspired by their curiosity to see how far they could push the peat level, as well as their partnership with Bairds maltings, who had batches of barley with irregular phenol numbers.   Although peat is intrinsically associated with Islay’s malts, things aren’t as clear-cut today – and as Hannett says, “You can’t categorise flavour by region”. Islay-based Bruichladdich produces both peated and unpeated whiskies. Originally the distillery made heavily peated malts, switching to unpeated styles in the 1960s, and today makes both. Its Port Charlotte brand was first conceived to capture what Bruichladdich would have been like in the old days, as a heavily peated malt. Intriguingly, Bruichladdich briefly tried using Islay peat, however found that they couldn’t get the phenol levels as high. Hannett highlights that another element in phenol levels is the depth the peat is cut from – with lower levels having more vegetation and therefore more phenols.  For Bruichladdich, when they’re looking for an overtly peated spirit, the quality of the underlying spirit is key – working with the right barley and fermentation times, for example. While peated malts might be thought of as heavy, oily and medicinal, they try to avoid this character. He deliberately won’t delay making a cut in the name of phenols, with that decision based on quality – and the result, he feels, is that, “The essence of the peat smoke is light – it’s barbecued.” For him, it’s about the balance between the peat character and everything else.  For blending specialists, House of Hazelwood, peated whisky “is a tool in our arsenal we can use to build a complex blend”, says Eilidh Muir from their Whisky Blending Team. She emphasises that using peat doesn’t necessarily equate to a smoky whisky, but can contribute something to a blend that is much harder to pin down – but something you’d notice if it wasn’t there. “A whisky dominated by a single flavour is often too one-dimensional,” she says – they too are looking for that fine balance.  Peat is just one element that can be used to shape a spirit – and there remains a certain amount of mystery to its influence. The sustainability question isn’t going away, but – as Bruichladdich’s Hannett says, “I don’t know what the solution is at the moment… but we’re looking for one.” As producers look for an answer, they’re pushing boundaries – experimenting with local sources and alternatives – something that will only benefit whisky-lovers, and the environment.  Browse a range of peated whisky or read more about spirits

How whisky distillers are using peat today

The big smoke: peat and whisky

Serge Valentin has been one of the few truly independent voices in the Scotch whisky world since the early 2000s. For two decades and counting, the Alsace-native has published his tasting notes and scores to an astoundingly large and loyal audience with his characteristically good humour and impartiality in what can be a deafening echo chamber.   Despite being one of the most well-respected authorities in the industry, Valentin has always written about whisky in his spare time, very much considering it a pastime that he dabbles in for fun. This is somewhat of a surprise, given the many people who part with thousands of pounds based on his views alone.  “Contrary to what many believe, I’ve never been a pro and have never actually worked in whisky,” the jaunty Valentin is quick to tell me. “It is all a kind of super-hobby to me and if you ever see me doing gigs, for example at whisky festivals, it is always for free, for fun and for friends.”   Valentin’s “proper work”, as he calls it, is in advertising and marketing, where he owns two agencies which employ around 2,000 people. These agencies, he says glibly, are “supposed to pay for my whiskies…luckily, they do”. It was a very different landscape when Valentin started writing about Scotch in 2002. Single malts had been marketed for 30-plus years but there wasn’t the seemingly insatiable demand and record-breaking prices that are commonplace today. It all began when Valentin, armed with bottles of his favourite Old Clynelish and Brora, sat down and shared his musings on his aptly named website WhiskyFun. This wasn’t a vanity project or a vehicle for freebies, this was a man writing about the whiskies he loved, just because he wanted to. From humble beginnings, WhiskyFun has become one of the most well-respected hubs for commentary on Scotch. Valentin follows a 100-point scoring system, like some of the great critics in the world of wine. For Valentin, however, 80/100 is a good score. His methodology is largely unchanged. He will spend an average of 30 minutes tasting a whisky (he does, on occasion, score rums and other spirits) – this can increase up to an hour if it’s a “good one” and take nearer 10 minutes if it is a “bad one”. He always compares several similar spirits, almost always from the same distillery, and never scores “out of the blue”. He tastes “alone, using the same parameters” (place, time of day, glassware, water etc.) and always writes as he tries, and then publishes once a day.  His write-ups are always short, honest, and unmistakably him. After all these years, it’s dumbfounding that he has the time or inclination to produce the near-constant stream of reviews that appear on his website.    It’s fascinating to see which liquids he scores – and, sometimes more intriguingly, the ones he doesn’t. “The choices rather depend on what I get and what I source, but my sample library is much larger than my tasting capacity,” he explains.   This all started as a passion project for Valentin and it’s abundantly clear that that fire burns just as bright today. He never takes himself too seriously and is evidently ill at ease with any comparison between himself and the greatly respected critics in the world of wine.    This is, in part, because the role of a critic in spirits is nowhere near as established as it is in wine. There are leading voices in the Scotch whisky world who undoubtedly carry considerable clout, but they aren’t critics in the traditional sense. While they might be prolific in their output and have seemingly healthy book retainers, they rarely score spirits and if they do, their tasting notes will be almost entirely positive (often because they are in a producer’s employ). The closest the spirits world has to a Robert Parker or Jancis Robinson MW is probably Valentin – although, he wouldn’t agree.   “I would say the roles are more and more the same in wine and spirits,” Valentin says, “even if there are fewer actual ‘critics’ in spirits. But it is coming in whisky.”  Valentin does feel there is a need for scores in collectable spirits, as – like wine – there isn’t always the opportunity for people to try before they buy. But the issue is not black and white, as is true of many things Valentin and I discuss.   “I see that scores [in whisky] become more like stock market recommendations these days,” he says.“I’m not too happy about that but that wouldn’t be the case if spirits, especially whisky, had remained a reasonably priced commodity,” he says, before adding: “But the cardinal sins are what they are.” It’s clear whisky drinkers respect Valentin’s voice, as they flock to his site in droves. What’s less clear, however – as an outsider looking in – is how producers feel about Valentin’s refusal to kowtow and sugar-coat his reviews.  “Producers have never quite known how to deal with independent voices,” he explains. “In general, they prefer influencers that they can pay and control, even if their audiences are smaller and less ‘on target’,” he adds, “for which I can’t blame them. Fortunately,” he continues, “not all distillers are the same. Some corporations are smarter than others and that often depends on the people within.”   When asked why he thinks people return to his site, which doesn’t have any of the bells and whistles you might expect from an ad man and is as no-frills today as it was two decades ago, Valentin says, as self-deprecatingly as ever: “I’m not really aware of everything that’s happening in the reviewing landscape, I have to say. If indeed people keep coming back to my assessment, that’s partly, I believe, because I started early and simply because they trust me. Trust is number one.”   In many ways, Valentin’s website is a collection. It’s a receptacle for his innermost thoughts and feelings about the things that matter most to him. Valentin has always been collector at heart. With an interest in stamps from childhood, he then graduated onto watches, wine and then whisky. The father of three has a broad and eclectic range of interests, including music (“all kinds”), advertising, motorcycling, wine, watches, food and travel which he has nurtured and indulged. Throughout the years, Valentin has had a front-row seat to the evolutions within these industries and the so-called art of collecting.   “Old-school collectors used to buy what they liked, never what was meant to see its value rise,” he says. “In the old days, you had to travel, to make phone calls, to go to festivals etc. Today,” he says somewhat ruefully, “you can buy anything, as long as you’ve got the money.” Valentin was ahead of the curve when he made the choice many years ago to buy as many different Old Clynelish and Brora single malts as he could, simply because they were his favourites. At the time, and up until 2005 to 2010, all whiskies – even the rarest – remained relatively cheap. After 2010, it was silly season and whiskies you could previously source were nigh on impossible to find or prohibitively expensive for some.  Valentin’s favourite whiskies have become some of the most desirable on the secondary market. Old Clynelish, produced before the distillery was rechristened Brora, have gained a huge following globally as people were charmed by the story and the characterful liquid the two distilleries produced. Now Brora is set to be re-opened, these single malts will only become more valuable. While his collection is no-doubt impressive – exact bottlings are not disclosed – there are some unicorns which still elude Valentin.   “Rather bizarrely and inexplicably, I prefer fatter spirits and fresher wines,” Valentin says, “in both cases with as little straight oak influence as possible. So, fat distillates, such as some coastal malts, some Jamaican rums etc. In wine, that would be the bright whites, Jura, Savoie, Rueda, Pacherenc, Irouleguy, Alsace, Wachau and Andalusia.”    “I know oak is crucial,” he adds, “you just shouldn’t feel it as such, according to my personal taste. But I insist, that’s personal.” Oak is a topic Valentin returns to several times. He feels it is the low-hanging fruit when it comes to innovation in the Scotch whisky industry.   “Sure, there are a few innovations around the casks,” he says, “but all makers use more or less the same.” The woods used are usually more active, which allows producers to sell much younger whisky for a good price while widening the ranges at the same time, he says.   “I’m not saying that’s bad,” he quickly adds, “but not many people are talking about the distilling regimes, the stills and so on, which was the number one topic 20 years ago.” He continues: “It is now all about wood. But, when we talk about wood that includes their flavouring with other spirits, wines, or even whiskies from other distilleries such as some peated ones, which is the latest trend, to peat single malts by doing some in-cask blending rather than bother with brewing and distilling some peated malt. “So, cutting corners for sure but on the other hand, I believe the average quality has risen pretty sharply. So, all remains good and well…”  This seems to be Valentin’s baseline. The whisky world might have changed but he believes it is the same at its core. There is an increase in branding and marketing (which is likely a source of joy and consternation for an ad man), there are more malts, and for the past five or six years, more distilleries from almost all countries.   “I’m not bored yet,” he says in his frank way, “and in general, whisky has got better on average, even if there are fewer utter glories and fewer total duds.”  If a man with Valentin’s reputation of no-holds-barred honesty is broadly happy, then we probably all should be too.   Browse all Scotch whisky  or  read more Editorial

Serge Valentin – the Joker in the pack

Serge Valentin: the Joker in the pack

Vega Sicilia is undoubtedly Spain’s most famous winery; a true icon in fine wine with a history dating back to 1864. Its success in retaining such a reputation, and in almost complete isolation in the Ribera del Duero region of Spain, is testament to the quality and consistency of its production, although its history has not been without its challenges. Vega Sicilia claims to be one of the longest-aged and longest-lived red wines in the world, with its flagship Unico capable of maturing in bottle for well over sixty years under the right cellar conditions. Developing its style in such solitary conditions has created a wine distinct from any other and whilst the Ribera region has flourished with the establishment of wineries such as La Pesquera in the 1970s and more recently the cult wine of Pingus, Vega Sicilia today remains at the apex of the appellation.  We explore the history of Vega Sicilia, the secrets behind its success and the changes afoot as it attempts to retain the traditional methods it has become famous for whilst modernising the winery and updating its processes. We also explore the contrasting range of wines it produces from the Valbuena to the Unico Reserva Especial: Vega Sicilia’s nod to the traditional Spanish practice of producing multi-vintage premium blends. The history of the estate The estate that would become known as Vega Sicilia was founded in 1864 by Don Eloy Lecanda Y Chaves, a Spanish vigneron who inherited the property in 1859. After visiting Bordeaux he brought cuttings of the Bordeaux varietals of Cabernet Sauvignon, Merlot, Malbec and Carmenere, as well as Pinot Noir, and planted 18,000 vines at the estate in Ribera del Duero alongside the native varietal of Tinto Fino (Tempranillo). By 1882 he had planted 500,000 vines on the estate, at the time known as Bodegas Lecanda.  The introduction of Bordeaux varieties was perhaps not that unusual at the time, since the Bordelais were becoming more and more influential in Spain (most notably in Rioja) having disbanded their operations in Bordeaux following the phylloxera outbreak and were actively looking for alternative regions to grow their grapes.  However, in Rioja, the Bordeaux varieties were soon replaced by the native Tempranillo which proved a much more reliable and profitable choice. Whilst Don Eloy Lecanda Y Chaves initiated a winery that was to change the history of fine wine, he was initially using the grapes to make brandy rather than still wine. Although the brandy was well received amongst the aristocratic families (no doubt piquing the interest of the Herrero brothers), the estate struggled financially to make ends meet and he died in 1894 never to witness the success of his venture.  The property was bought by the Herrero brothers in the early 1900s who renamed it Vega Sicilia. As phylloxera eventually reached Rioja, the négociant Cosme Palacio was looking further afield to maintain supply for his customers. On discovering Vega Sicilia, he immediately rented the property from the Herrero brothers.  He brought with him winemaker Domingo Garramiola Txomin who introduced the Bordeaux techniques of ageing wine in barrique as well as extending the élevage. He also initiated bottling the wine on the estate (Cosme Palacio was previously shipping the wines in bulk to Rioja).  The Herrero Brothers were a well-connected upper-class family who were galvanised to produce a wine of exceptional quality no matter the cost, to sell to their aristocratic friends. This quest for quality combined with the skills of Domingo Garramiola Txomin, as well as the unique combination of Bordeaux varieties and Tinto Fino (thanks to Don Eloy Lacanda Y Chaves), was the perfect recipe for producing Spain’s first iconic wine – Vega Sicilia Unico. The first vintage of Unico was produced in 1915.  Thanks to the connections of the Herrero brothers, within two decades Vega Sicilia had become the most revered winery in Spain. Even at this time the wine had built up a reputation for its extraordinary ageing capacity. At Vega Sicilia the Bordeaux varieties became a key component to their flagship wine of Unico and have remained in the blend right through to the present day. Throughout this time, the property became almost a self-contained village, with a school and chapel on site and many of the families working at the winery and living on the estate. Despite the winery changing hands a number of times over the last century, Garramiola’s legacy has lived on through the winemakers that followed in his footsteps; figures like Martiniano Renedo, who was initially Garramiolo’s assistant, and especially Jesús Anadón, who was instrumental in maintaining the quality and reputation of the wine through the middle of the 20th century.  Amazingly there are workers on the estate today whose families have worked at the winery for generations. Today the master cooper at Vega Sicilia, along with his brother Jesus Yanez, is the fourth generation of his family to work at the property. The winemaker between 1968 and 1998, Mariano Garcia, was the son of one of the farm workers on the property.  Despite its global reputation, its exclusive allocation list and long history, the winery and vineyards went through bouts of dilapidation during the 1950s, through to the late '70s, whilst at the same time producing some of the most legendary vintages. On purchasing the property in 1982 the Álvarez family began to make huge investments into the estate, renovating the winery and carrying out an extensive replanting program in the vineyards. 1982 was also the year Ribera del Duero was awarded its DO appellation status and no doubt helped further promote Vega Sicilia as the historical icon of the region. The winery and the appellation has never looked back since.  In the vineyard Vega Sicilia is situated on what is known as the “golden mile”, a stretch of road between Pañafiel and Tudela de Duero, where the prestigious wineries of Vega Sicilia, Pingus and Pesquera are all situated. Driving through, it is a somewhat underwhelming sight as far as vineyard vistas go, so much so you could almost pass through it without noticing.  Being an altiplano there are no sweeping mountainous views, you only feel the altitude from the freshness of the air. In the higher vineyards of Soria at the edge of the Ribera appellation you are rewarded with more vistas, as well as a sense of history with evidence of prehistoric cave-like dwellings where farmers sheltered from the extreme climatic conditions of this largely desolate region.
 Whilst there are pre-phylloxera ungrafted vines dating back over 100 years dotted around the region, the vines at Vega Sicilia - with vineyards at 700 meters - average around 35 years of age. Vega Sicilia have an extensive replanting scheme in their vineyards preferring the quality of their fruit in their mid-life as opposed to old age, with typical vine age in Unico around 60-65 years old, with the younger vines going into the Valbuena cuvée. The high altitude and continental climate mean extreme conditions are at work in the vineyards. Winters can be very cold whereas the summers can be fierce. Most notably in regards to grape growing, due to the altitude, there is a huge diurnal shift in temperatures from day to night helping to retain the acidity and freshness in the grapes whilst reaching high levels of ripeness. The main grape in all Vega Sicila wines remains the Tinto Fino (the particular clone of Tempranillo) distinct to the region. The Tinto Fino is said to produce smaller berries with higher concentration of tannins compared with the Tempranillo grown in Rioja. The Unico also has a proportion of Cabernet Sauvignon in the blend (anything from 6-20% in more recent releases) with a higher proportion in older vintages. In the Valbuena, the majority of the blend is Tinta Fino with a small amount of Merlot (typically 5%) . The property is huge in scale with 200 hectares of estate-owned vines producing anything from 40,000 to 100,000 bottles of Unico each year depending on the vintage.  
In the winery
 Unico  The style of the flagship cuvée of the winery has remained virtually unchanged since its inception in terms of production, although assemblage has modernised. Élevage times have reduced and the influence and proportion of Bordeaux varieties has become less in more recent releases.  In the past, Unico was only made using huge 40,000-litre fermentation tanks (this was all that was available at the winery) therefore in a difficult vintage, if this sort of volume was not possible at the quality level they expected, then no Unico would be released that year. Since 2010 the winery has introduced smaller 8,000-litre tanks, enabling smaller micro-vinification of their wines and suggesting a release of Unico every year (in varying quantities) is more likely. The winery today operates at a spec similar to the top estates in Bordeaux. They have introduced 81 separate fermentation tanks allowing them to carry out intra-plot fermentation. They have introduced highly sophisticated sorting tables, there is more temperature control of the wine and the winery is now completely gravity fed enabling greater precision when it comes to winemaking.   Following fermentation, the wines destined for Unico are blended in small oak barriques (50% French oak / 50% American oak) for 12-24 months depending on the vintage. The French oak is 100% new whilst the American oak, coopered on site, tends to be one to four years old. Following barrique ageing, the wine is then transferred to large old oak casks where it typically matures for five years before being bottled and aged further prior to release. Unico is typically released at 10 years old. Valbuena 5° The Valbuena typically comes from the younger vines of the estate and is aged in oak in barriques for 12-18 months before being transferred to larger old oak casks for a further 18 months prior to bottling. It is then aged for two years in bottle. Valbuena is typically released at five years old. Unico “Reserva Especial” The Reserva Especial is the mythical bottling that initiated the Vega Sicilia legend. It is made up of choice parcels from a blend of vintages (in recent releases it tends to be select parcels from three vintages). Prior to the 2001 release, details of the blends of older bottlings are not very easy to come by. With only 15,000 bottles produced this is the rarest cuvée from Vega
Sicilia and a nod to the traditional multi-blend wines that were typical prior to vintage specific bottlings becoming more popular in the mid to late 1800s. Explore more Editorial
