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

The big smoke: peat and whisky

For the aperitif For Domaine Long-Depaquit’s Matthieu Mangenot it is the energy and power of Champagne Brut Nature Les Marnes Blanches from Jeaunaux-Robin, that makes it his choice at Christmas. “I can't say for sure if it is the 100% Chardonnay selection or the very elegant vinification in Burgundy barrel that is this Champagne’s (hidden) tribute to our region but there is absolutely no ‘make up‘ with this Champagne. With no dosage it is a true expression of Chardonnay and terroir. To me, it is the best sparkling to get you ready for Christmas dinner!”  Klaus-Peter Keller (Weingut Keller) and his family love Champagne Bérèche & Fils or Krug, “but we will definitely enjoy some sparkling wines from Germany too!” he adds. Gianlorenzo di Neri from Montalcino’s Casanova di Neri is also choosing something local, with a 2002 Trentodoc – Giulio Ferrari Riserva del Fondatore, as well as a family favourite, Champagne Egly-Ouriet’s Blanc de Noirs. Saskia de Rothschild (Ch. Lafite-Rothschild) breaks the mould and prefers to drink ice-cold Sauternes as an aperitif rather than sparkling wine. She is still toying on whether to go young or old, deciding between a 2017, an 2007 or 1989 from Ch. Rieussec. The whites White Burgundy seems the overwhelmingly popular choice for the Christmas table. Francisco Baettig (Viña Errázuriz, Viñedo Chadwick and Baettig wines) opting for a bottle of Pulingy-Montrachet Les Combettes from Etienne Sauzet. “I love the elegance and balance of this appellation, and the purity of the wines from this producer.” Neri is saving his last bottle of 2005 Bourgogne Blanc by Coche-Dury alongside a 1991 Terlano Rarita, a Pinot Bianco blend released 25 years after it was made, proving the incredible ageing potential of top whites from Alto Adige. Mangenot has also opted for a rarity for the special day – a magnum of 2012 Nuits-Saint-Georges Blanc from Château-Gris (Albert Bichot). Chardonnay accounts for just 2% of the Nuits-Saint-Georges appellation. “The wine has a lot of richness and a beautiful tension due to the altitude of the vineyards,” says Mangenot: he is pairing it with cod fillet and citrus cream. Keller is bucking the trend and unsurprisingly opting for dry Rieslings, specifically from the 1990s, along with an eagerly awaited bottle of 1959 Mosel Piesporter Schubertslay. In 2008, Keller (although based in Rheinhessen) took over 0.7 hectares of this incredibly steep slope in the Mosel and he is using his Christmas dinner to do some research on this Mosel site with some serious bottle age. The reds Keller is not holding back on the reds: he’s got a 1966 Ch. la Mission Haut-Brion and a 1991 Clos de la Roche Grand Cru from Hubert Lignier lined up. Gianlorenzo di Neri is also opting for a Clos de la Roche, although his is a 2006 from Armand Rousseau. At the Neri household they love to compare Grand Cru Burgundy with their Brunellos, “It should be amazing to taste our 2006 Tenuta Nuova alongside.” Beyond Brunello and Burgundy, they will also be enjoying some top Nebbiolo, but it’s not an easy choice. “For Barolo we love so many producers, Elio Grasso’s Runcot – 2008 should be delicious now – or possibly Giacosa’s 2007 Barbaresco Asili Riserva.” For Mangenot, “The middle of winter is a good period to open a bottle of sunshine like Cornas Vin Noir 2012 from Domaine du Tunnel (my wife loves it!) – concentration, density, beautiful complexity, silky tannins… And a bunch of aromas that turns your dinner into a summer journey in a convertible car with your nose in the wind!” Beattig is also opting for Northern Rhône Syrah from his favourite producer Pierre Gonon, a Saint-Joseph. “I love the complexity of aromas, the spiciness. The structure of the wine, but at the same time the polished tannins. The mix of freshness, complexity and depth... love it.” At the Rothschild household it will of course be Lafite: “1988 or/and 1996: two absolute favourites of mine these days,” Saskia explains. “The 1988 is pure Lafite, extremely complex and evolving and the ’96, thanks to its perfect balance, is just so easy to drink that you’ll finish the bottle without even noticing it.” Jean-Guillaume Prats (CEO of Domaines Barons de Rothschild Lafite) is staying pretty loyal too, opting for Pomerol’s Ch. l’Evangile 2010. To finish Finally the sweets and fortifieds: there is never a better time to open aged Ports to go with the cheese and desserts of Christmas. For Lafite’s Jean-Guillaume Prats it will be Dow’s 1977 – in his words, “perfection”. Mangenot is also going for Vintage Port: Graham’s Quinta dos Malvedos 2001, “to go with a homemade chocolate mousse, and the rest of the bottle definitely to enjoy slowly by the fire with the family… Fruits, flowers, creamy character, it is a treat for the nose and the palate I wouldn't miss it at any price.” Keller decides on the sweet wines more spontaneously: “One of our favorite combinations is matching 40 and 50-year-old Ausleses with game dishes. It can taste so great. The anticipation is already great.” If fortifieds are not your thing, then take Jean-Sébastien Philippe of Lafite’s recommendation: he’ll be having a glass (or two) of Cognac de Lafite Très Vieille Réserve. He believes it is one of the most astonishing selections of old eaux-de-vies in Cognac. Browse our full range

There’s no better time than Christmas to open a treasured bottle or two. Ahead of the big day, we asked a handful of our favourite winemakers – from Saskia de Rothschild to Klaus-Peter Keller – to tell us what they’ll be uncorking

What winemakers are drinking this Christmas

Christian Patat is one of Italy’s busiest and most successful vignerons working with his wife at top Friuli estate, Ronco del Gnemiz, as well as working with Enzo Pontoni, vigneron extraordinaire, at the legendary Miani estate. He also works as a consultant winemaker for many properties producing wines from all over Italy. Most recently he has been involved in an old vine project with long-term friend and fellow Friulian, Marco Simonit – famed for his work protecting old vines all over the world most particularly at the legendary estates of Yquem, Leroy and Louis Roederer.

We caught up with Christian to talk more about L’Età Più Bella (With Age Comes Beauty), which is set to release its first collection of wines from top sites in Friuli next month. His insight into the Friuli region is a great starting point to understanding Italy’s mecca for white wine.
 Can you describe what you think is so special about the Friuli region for wine production?  "Friuli is one of the most complex scenarios in the wine world given the unheard of combination of grape varietals, soil identities and climatic challenges. I’ll try to explain from the inside. The wide number of varietals is provided by different waves of invasion, such as
the French (at the time of Napoleon) and the Austrians (in the same period of Napoleon
but they stayed for much longer); these invasions explain why we have so many 
Bordeaux varietals (Merlot, Cab Franc, Cab Sauvignon, Carmenere) and others of
French origin such as Pinot Blanc, Pinot Gris, Chardonnay and Sauvignon. "The arrival of these 'imported' wines did not cancel out the presence of local varietals such as Ribolla Gialla, Refosco, Schioppettino, Pignolo and Tocai Friulano. The Austrians also did their part leaving some Traminer and Riesling so that the picture is composed as it is today.  "Until the ‘60s, Friuli was a poor region and the vineyards were in the hands of small growers selling locally and with no real commercial plan and having the ability to offer a wide range of wines gave more options to sell to occasional customers. For this reason, the Friulians never gave up any of these varietals and when the DOC was finally in place they were all included.  "In terms of soils there is a significant difference between the flat appellations (Grave del Friuli, Isonzo, Aquileia) and the hillside appellations (Collio, Friuli Colli Orientali, Carso). The flat area is basically made of gravelly soils, the hillside is basically marl (locally called PONCA and geologically called FLYSH), obtained by the sea pushing in the direction of the mountains and creating slates of chalk, limestone and clay, all of which are agglomerated in various percentages and sometimes within the same vineyard, providing an incredibly complex subsoil.  "This complexity is augmented by the fragility of the structure which is very prone to erosion and obliges the growers to cultivate on terraces in order to minimize the impact of the water. This way of growing the plants generates very high costs and consequently low yields given the limited density of plantation (i.e. the average density on a modern planting in hillside Friuli can reach about 6.500 plants/ha which is much less than what can be achieved in Burgundy with an average of 10.000 plants/ha), and makes virtually impossible machine harvesting and other mechanical intervention.  "To complicate this picture, Friuli has the highest amount of rain in Italy which means that growing grapes can be a real challenge, but the ponca soil has a high degree of draining, so to avoid issues and diseases caused by excessive water close to the roots. All this being said, the real peculiarity comes from the soil itself which can be a magical balance of minerally driven characters, with enough structure to provide full-bodied wines and that’s the
reason why white and red varietals are grown in the same place." What varieties do you think perform the best in Friuli and why?  "You may have different answers if you ask different growers but personally I think that among white wines I would go for Friulano (Tocai) because it expresses very well the different sites and shows better than any other varietal the balance of richness and saltiness.  "Apart from Friulano I would pick Sauvignon Blanc because I see it as a possible third way
between Loire and New Zealand. More aromatic than in France with richer body
and more minerally driven than in New Zealand.  "And finally, if you are lucky enough to have well-aged vines Chardonnay can also do surprisingly well in cold sites. Among reds I would pick Merlot and Cabernet Franc given their tendency to ripen on the late side (same timing as Pomerol and Saint Emilion) and to
provide low yields and concentration without losing freshness and spice. Also, Refosco can do very well bringing a Syrah-like spiciness and a full body but it needs to be grown in very well-suited spots. Can you describe the last few vintages and qualify them?  
"2018 was a very sunny and dry vintage, driving to early ripening of some of the whites such as Sauvignon (starting date of harvest 23rd of August) but quite interesting for reds given that the month of September was quite fresh and dry so to give a larger window to pick the reds at the right level of ripening. 2019 was much cooler (starting date of harvest 1st of September) but quite ideal for whites with lively acidities and good concentration. Reds were also fine but some later rain in September affected a bit the possibility of fully ripe tannins so I would consider it as quite average." 
10 DOCs, 4 DOCGs, 30 different varieties, it can be difficult to know where to start exploring the wines of the region. Can you advise?  "Diversity can be fascinating but it can also turn into a nightmare given that you have to add also the wide difference of styles available (stainless steel crisp white wines, barrel fermented Burgundy oriented, orange wines with maceration on the skins…). I cannot really advise on this as I find all this diversity as a real limit to communicate the character of the region, but on the other hand I have to admit that there are very few wine regions in the world (maybe none) where you can find so many reasons of interest. That’s why more and more wine enthusiasts are travelling this way and fall in love with the complexity of these terroirs and
wines." 
Are all the fine wines of the region concentrated in one area or are they dotted all around?  
"90% of what we can call fine wines are made on the hillsides of Collio, Friuli Colli Orientali and Carso and very few are made in flat appellations such as Isonzo." 
Friuli-Venezia Giulia comes across as quite independent from the rest of Italy, why is this?  "I think a whole history of invasions (Romans, Longobardians, Venetians, Austrians, French) has created a sense of self protection. More than this after the Second World War Friuli has turned from a poor region into one of the very wealthy and productive areas of Italy, due to
the silent and consistent attitude for hard work of the Friulians. They have been able to turn it into a well-kept secret and make a pride of it." How long have you worked at Miani?  "I started in 1991 helping him in decision-making at the time of the final blending and taking on my shoulders all the commercial aspects that he did not want to manage." What makes the wines from these top wineries stand out?  "I don’t know if they stand out but what I can surely say that we both apply a tireless dedication and passion to what we do. We both consider single sites and soils more important than varietals and we have the ambition to 'bottle a place' more than a wine." Who has been your biggest inspiration in life and as a vigneron and why?  "My father, a real bon vivant, who put me in contact with great wines since I was still very young and created in my mind the quest for quality in every aspect of my life. My fascination for great wines came from him, just watching his excitement when receiving his annual allocation of Champagne Salon or Monte Vertine (to name a few) and the pleasure he used to take in sharing with friends.  "Then my wife who despite challenges, family issues, economical limitations never gave up looking for the best possible wine here at Gnemiz, loving this place and respecting it as a living treasure and not just as an instrument. Finally Enzo Pontoni at Miani who showed me how you can achieve your goals only with hard work and passion and how you can be the happiest man on earth just for the fact that you are doing exactly the work you want to do in the way you want to do it." How did you first get involved in L’Età Più Bella (With Age Comes Beauty), the old vine project?  "That was Marco Simonit's idea to involve me as we had experimented in the past and in some ways we started the project in the mid ‘90s, but at that time we were all too busy to follow up and we did not have a well-formed concept of what we could do… we were just youngsters…" What is so unique about the wines that have been produced under the L’Età Più Bella label?  "The goal was to explore the identity of various plots of very old vines, all of which were well placed with very good exposition and with an excellent quality of soil. The character which comes out from an old vineyard has a different kind of balance and texture, as we use to say, it is more a “wine of roots” than a “wine of sun”. That’s quite evident by the fact that old vines tend to ripen later than neighbouring young vines and suffer much less from potential water stress, producing more consistent wines of complexity and finesse. We were not looking for fruit bombs to impress but for refined and subtle characters and ageing potential."
 You are a philosopher and a jazz musician as well as a winemaker. Can you tell us more about these passions?  "That’s all too generous, in fact, I have none of these titles. I did not complete my studies in philosophy due to the sudden death of my father so I cannot call myself a philosopher. My passion for philosophy is due to my classics studies and when it was time to chose the University, my father suggested to go for philosophy because, he said, 'when you will
finish your study you will not find a job and can come to help me to sell some
wine!'  "That’s exactly what happened, just with the wrong circumstances. About jazz, I always wanted to become a piano player and I’ve studied a lot for this but in the end, I was not good enough to make a career and I quickly understood there was no point in dreaming of being the new Keith Jarrett, so I became a well trained amateur and I gave up playing in public.  "As for winemaking, I don’t have a formal education given that I had to work and did not have time to study at University, so I started a process of self-education in a kind of backwards process, from my instinctive ability to be a good taster, moving gradually to all the
knowledge which drives the production of wine, from the vineyards to the cellar.  "It took me years and the support of many friends who allowed me to verify my skills in their cellars. The results of my 'experiments' were very promising and convinced me to go deeper in my studies until the point of being able to take full responsibility for wine production as I’ve been doing for the last 20 years."
