Bordeaux is changing. The Left Bank, in particular, has long been a region of labels – of grandiose estates, polished winemakers and the bottles they produce – the vineyards a backdrop to their impressive châteaux and new state-of-the-art wineries. Of course, vineyards have mattered, as much as they’re the source of their grapes, but they’ve rarely been the focus for conversations with trade or consumers. But now, perhaps influenced by the meteoric rise of Burgundy – and an approach to wine echoed around the world, terroir is stepping into the spotlight. Behind the scenes, the Bordelais may always have been looking underfoot, but now they are talking about it too.  Nowhere is this more true than at Ch. Montrose – a property that announced a significant change when releasing its 2023 vintage. The property has always made some of Bordeaux’s finest wines, but over the past 15 years (under the Bouygues’ ownership) quality at this Saint-Estèphe estate has reached new heights. Long known for its austere age-worthiness, there’s now a modern polish that softens its stern style – without sacrificing its classicism and longevity. Each vintage seems to reveal a new level of precision and finesse. From 2023, Montrose announced that its Grand Vin would only come from Terrace 4 (T4). If that doesn’t mean much to you, I’m not surprised.  The Médoc and Graves’s six gravel terraces were uncovered by Pierre Becheler in a series of studies in the 1980s and ’90s. Each terrace dates from a different period and has its own distinct soils, with Terrace 1 (T1) the oldest and Terrace 6 (T6) the youngest – and argued to be a defining factor in the Left Bank’s terroir. T3 and T4 are widely regarded as the best for wine-growing, and Becheler found that, at the time of their classification in 1855, over 80% of the Classed Growths sat on these two distinct geological strata.  In the last decade, these gravel mounds have become a key part of Bordeaux’s story, explaining the estates’ terroir. Despite widespread understanding that the terraces are integral to the quality of wine, there still isn’t a comprehensive map of the Left Bank’s terroir – showing which vineyards sit on which soils (the best are those created by Jane Anson and Kees van Leeuwen for Anson’s book Inside Bordeaux). Most studies have been undertaken by individual estates, as at Montrose – who engaged Becheler himself to uncover the specifics of their site.  It's remarkable that, without knowing anything about the region’s subsoils, Montrose was so fortuitously placed – although it has of course survived thanks to its prestigious site. The property’s first vines were planted – all on the fabled T4 – in 1815, by Etienne Théodore Dumoulin, who had purchased the land from Nicolas Alexandre de Ségur (of Calon Ségur). The land had been covered in heather, its pink blossom covering the gentle slope come autumn, and sailors passing along the Gironde estuary used to call it the pink hill – or “mont rose”, giving the property its name.  It was only 40 years after the first vines went in the ground that the estate earned its place as a Second Growth in the 1855 Classification. By 1861, when Dumoulin passed away, the estate comprised 95 hectares – but its borders have shifted over the years. It was later purchased by an Alsace factory owner, Mathieu Dolfus, who invested heavily in the property. He was a visionary – offering free healthcare, profit sharing and accommodation on the estate for his workers. He even used a wind turbine to flood the vineyards, staving off the impact of phylloxera as long as he could.  Montrose was managed by the Charmolüe family between 1896 and 2006, with Jean-Louis – who ran the estate from 1960 – key in building its modern reputation. It was under him, in the 1970s, that vines were planted on lower-lying land close to the estuary, which sits on T5. These humid, sandy parcels are now used for La Dame de Montrose, the château’s second wine.  It was in 2006 that brothers Olivier and Martin Bouygues (of the eponymous telecoms company) acquired the property. In 2010 they bought an additional 22 hectares from Phélan Ségur, land which had historically been part of Montrose. These vineyards, wooded on either side, sit on the sandier T3, but importantly also brought the total vineyard area back to 95 hectares – as under Dumoulin – and all sitting in one block (something which is relatively rare in Bordeaux).  The Bouygues brothers hired Vincent Decup as the estate’s Technical Director in 2014. Decup instantly set about getting to grips with the estate and its soils. When he arrived, they had a map detailing 16 different soil types across the vineyards – but he soon commissioned further studies, uncovering an additional 10 soil types. This gave them, Decup tells me, “the possibility to explore and separate” parcels, diving into the detail of the site with a Burgundian, rather than Bordelais, vision. From 2017, the team started delineating the parcels – vinifying plots in 93 separate tanks (over twice the 40 that had been used just three years prior), adapting the winemaking to each. Looking at the Cabernet Sauvignon on T3 and T4, he explains how they gained a “new level of precision and comprehension of Cabernet on each terrace”.  “The Cabernet Sauvignon of Montrose naturally gets lots of power,” Decup tells me. “We have to be careful with the extraction.” Especially for fruit from T3, he explains, it can easily become overly austere. T4 has always represented the majority of the blend for the Grand Vin at Montrose – and in Decup’s mind it is not just the property’s historic DNA, but what gives the wine its identity. He tells me how there is something magical about the way Cabernet ripens on these parcels, developing technical (sugar), aromatic and phenolic ripeness all at once. It produces wine that is “powerful, voluminous, demonstrative – a lion in a cage”.  In 2022, the same year that Charlotte Bouygues took over as President and Pierre Graffeuille became CEO, the team started focusing more on T4, and from 2023 the Grand Vin comes exclusively from this prized terrace. Coming from the Delon estates, Graffeuille knew the potential of these soils, shared by Léoville Las Cases. The 2022 vintage was pivotal – earning four potential 100-point scores, with four firm 100-point scores in bottle – and the 2023 followed in its footsteps, with three potential perfect scores to its name.  The gravel terraces rise and fall through the region. T4 surfaces in Saint-Estèphe, running under Meyney and Montrose, disappearing until the southern edge of Pauillac, reappearing around Latour, then running through much of Saint-Julien (including the three Léovilles – Las Cases, Barton and Poyferré – and Ducru-Beaucaillou), rising again throughout Margaux and then again under Haut-Brion and La Mission Haut-Brion, with small pockets further south.  The defining factor of T4 is an iron pan beneath its sandy gravels. The sandy gravel topsoil allows young vines to develop roots easily, before they hit the compact iron layer – forcing the vines to spread horizontally rather than vertically. That compact layer is cool and retains water, feeding the vines in hot years. Decup explains how in July the topsoil might be hot, but if you dig down you can feel the chill of the iron layer – something that is perfect for Cabernet Sauvignon. At Montrose, T4 sits between 12 and 16 metres’ altitude, while elsewhere it reaches a maximum 22 metres. T4 tends to run close to the Gironde, which provides a moderating influence – especially so at Montrose, where the estuary is 4.5km wide (notably protecting the estate from frosts, such as in the brutal 1991 season – a year when Montrose produced the wine of the vintage).  As with T4, T3 runs beneath many Classed Growths – notably Cos d’Estournel, Mouton and Lafite. With sandier gravel topsoil, the key difference is that T3 doesn’t have the iron pan of T4 – the topsoil instead sitting directly on clay-limestone subsoil. Slightly higher in altitude (15-18 metres at Montrose, but generally 20-26 across the Médoc), the soils are very deep and the vines’ roots drive straight down, up to three metres or so at Montrose, Decup tells me. With less clay in the topsoil, the soils are particularly free-draining, and the vines reach down in search of water. “In terms of expression, it is not the same at all,” says Decup. He explains that while it also produces bold Cabernet Sauvignon, it’s got particular energy and length, an austerity – but “positive austerity”. Vines on T3 particularly thrive in hot, dry years, he tells me.  Montrose has an impressive 45 hectares of vines on T4, 12 on T3, a swathe on what the team describes as an “intermediate soil” – somewhere between the two terraces, and a small portion on T5. So what now of the property’s vines on T3? While the château isn’t openly confirming it, a separate bottling of T3 is set to be released – likely hitting the market in 2026, if rumours are to be believed. The rest of the fruit goes into La Dame de Montrose, and a small portion into a third wine, Tertio de Montrose (previously known as Saint-Estèphe de Montrose), which is exclusively for those working at the estate. All in all, the Grand Vin now represents circa 36% of production at Montrose – down from closer to 45%.   “T3 and T4 are, in our opinion, the terraces that produce the best viticultural results,” says Pierre Becheler, when it comes to the Médoc and Haut-Médoc. Interestingly he explains that in the Graves it’s very different, and T2, which is almost non-existent in the Médoc, produces some stunning results. He can’t fully explain why one terrace works better for wine than another, but one reason the terraces are so important is their influence on water availability. With varying proportions of clay and sizes of gravel, it’s a key element in viticulture and, eventually, wine quality. Although he has spent much of his career diving into these gravel beds, however, he’s very clear that the terraces are one very important piece of the puzzle – but will never provide the entire picture. Some terraces are the best in certain appellations, he says, “but we don’t really know why or how”.  The complexities of Bordeaux’s terroir are manifold – and some argue that the bedrock, from richer clays to hard limestones, are more influential than the gravel terraces that lie over them. On top of this, slope exposition, proximity to the Gironde, and many other elements influencing microclimate, not to mention the human influence, all contribute to the concept of “terroir”. It’s exciting to see site pushed to the fore, especially alongside an increased focus on sustainability in the vineyard. The conversation is evolving – and, if Montrose’s 2023 is anything to go by, it’s only going to push quality in the region higher than ever before.  Explore all current Montrose listing (including a special selection of ex-château stock) or read more about Bordeaux

FINE+RARE: Talking terraces and terroir with Ch. Montrose 

What lies beneath: talking terraces and terroir with Ch. Montrose  

Ian Chang is one of the most well-respected and accomplished whisky makers in the modern era. After 16 incredible years at Kavalan, in which he and the distillery went from unknowns to untouchables, Chang is embarking on a new adventure. This time he is turning his sights to one of the most exciting whisky-producing regions in the world: Japan. You’d forgive Chang for being egotistic. Over the past decade and a half, the Taiwan-native has received countless awards and accolades for his Kavalan single malts and is fawned over by whisky lovers and the press. And yet, even through his medical mask – there are still Coronavirus restrictions in Japan when we speak via Zoom – on a slightly pixelated screen, you can feel a genuine warmth and kindness emanating from the Master Blender. He is fiercely intelligent, good-humoured and modest. When it was announced in 2020 that Chang would be leaving Kavalan, the news was met with surprise and intrigue. Why was he leaving? Where might he work next? Would he stay in Taiwan? “The reason why I left Kavalan is because I wanted to change to a different environment,” Chang tells me from his new office in Japan. “Before this project, I only had experience in Taiwan,” Chang explains. “Producing whisky in a hot climate, which means that age statement whisky can virtually not be produced due to very high angel share.” Chang says he immediately signed onto the new distillery project spearheaded by Karuizawa locals Koji and Yoshie Shimaoka. While some details are already in the public domain about Komoro, located near the fabled original Karuizawa distillery site, this is the first time Chang has spoken at such length about his intentions for the new Japanese whisky distillery. “In Japan, in Karuizawa, they have a very similar climate to Scotland, so our plan is to produce whisky with age statement,” he tells me with glee. The first Komoro age statement will be a 12-year-old, followed by a 16- and 20-year-old. Thereafter, the age statements will increase in five-year increments, Chang says. There will be some non-age statement bottlings before the whisky reaches the 12-year mark. “So hopefully I can see my very first 40-year-old whisky,” he says with a soft chuckle, “If I’m still alive – fingers crossed.” Chang joined the whisky industry as a novice (or “from zero” as he calls it) in 2005. After graduating with a degree in food technology, he applied on a whim to a role at Kavalan’s parent company. Despite his lack of experience, Chang passed the interview stage, which required him to identify flavour notes in whisky, with flying colours. For the first year, while the distillery was being built, Chang voraciously read everything he could on whisky. Then, in 2006, the young whisky-maker-to-be met a man who would change his and the distillery’s destiny: Dr Jim Swan. “That was when the official learning started,” Chang tells me. Dr Swan – who was dubbed the “Einstein of whisky” for his pioneering scientific research and ability to help new distilleries with his unparalleled whisky production and maturation know-how – began by teaching Chang the fundamentals. This education took the best part of three years and covered everything from malting, milling, mashing, fermentation and double distillation. By the time the very first Kavalan Classic Single Malt was released in year three, the team knew they had produced something exceptional, and it didn’t take long for the wider whisky world to start taking a keen interest in Taiwan, Chang and Kavalan’s ground-breaking techniques. Not that Chang would say as much. Ever humble, he continues: “That’s when my focus with Jim Swan switched to blending.” The duo travelled extensively, visiting cask suppliers across Europe and the USA, while Dr Swan taught his protégé everything he knew about whisky from his 40-year career, and, you sense, his learnings from the school of life. When Dr Swan suddenly passed away in 2017 at the age of 75, he left a gaping chasm in the industry and many people’s lives, Chang included. Five years after his mentor’s sudden passing, Chang occasionally uses the present tense when talking about Dr Swan and takes a nano second to compose himself before he continues with his train of thought. The reverence and respect is clear to see. Of all the people Dr Swan taught, directly and indirectly, Chang spent the longest time under his tutelage, and he continually credits him for every success that he has had. For his latest project at Komoro, Chang said he wants to “bring Japanese whisky to the next level” by applying the many techniques he learned from Dr Swan. It’s a brave move in more ways than one. Chang has relocated to the country and doesn’t speak the local dialect, yet – but he is very grateful that his local colleagues are willing to learn and speak English to him. He is also joining a whisky-producing region that is at a very interesting crossroads in its history. It was announced last year that new regulations will come into force in 2024 which stipulate all liquid labelled as “Japanese whisky” must be produced (from fermentation to bottling) in Japan. This undoubtedly wouldn’t have been a problem for Komoro but it does mean several very high-profile competitors are scrambling to change their practices accordingly. Chang doesn’t comment on this but he does say: “To be honest, so far, I think all the major producers, such as Suntory and Nikka don’t really use STR [Shaved, Toasted and Re-Charred casks] at the moment. “So, by introducing Jim’s technologies and also his way of new-make production we are going to enrich the spirit produced in Japan and make a whisky which will be very much more enjoyable for consumers to enjoy globally – this is our aim for the future.” One of Dr Swan’s most famous contributions to the whisky world, and Kavalan specifically, was STR (Shaved, Toasted and Re-Charred casks). The invention was born out of necessity in 2010 when shortages of refill casks began to cripple the industry. Chang says Kavalan was in “serious trouble” because the distillery was a mere four years into production and couldn’t secure any re-fill casks for their new-make spirit. It was then that Dr Swan suggested the team used ex-wine casks instead of the in-demand refill Bourbon. This was highly irregular; ex-wine casks were undesirable because of wine’s organic acids, which would spoil the whisky and make it astringent. Simply, the process of shaving, toasting and re-charring casks removes the unwanted acids, breaks down the lignin structure of the wood to release wood-related compounds (including the desirable vanillin and caramel notes), and imparts a nice, sweet character to the spirit.  When asked what the secret is to producing an exceptional whisky, unsurprisingly Chang’s answer has been heavily influenced by his mentor. For Dr Swan, it was always about layering flavours and textures. “We want to make sure that it’s a rich and complex whisky but at the same time, very balanced without any off notes. To Jim, off notes were a big minus in terms of quality and that is why distillation and fermentation is also very critical in addition to wood policy,” Chang explains. “Because off notes can come from three places: fermentation, from the wood and also from fast distillation, these are the three areas that Jim always paid attention to.” This attention would include visiting cask suppliers regularly and ensuring distillation is slow to promote interaction between the new-make and copper. He would also keep a close eye on fermentation so the temperature increases from the beginning until the end. For Chang, and Dr Swan, there is a science and an art to whisky making and blending. “When it comes to marketing, especially during masterclasses, sometimes you’ve got to tell a little bit of stories so that’s when parts of the art and romance come in,” he says, laughing gently – making him even more endearing. “But to be honest, to be a blender, sometimes you have to use your imagination as well. You have to imagine how a Sherry cask will blend with a peated new-make, for example. “Jim always said, whisky making is a combination of art and science. And I think it’s maybe half, half. I think if you don’t have good imagination, you cannot really be a good blender but if you don’t know the science and just know the romantic side you cannot produce good new-make to begin with, so you have got to combine the two to make sure that the new-make and the wood go very nicely together.” During his 18 years in the industry, Chang has seen a lot of change. With new distilleries opening at a staggering rate and lost icons being brought back to life, there has arguably never been a more exciting time to work in single malt whisky production. Chang agrees and says things are looking “very bright”. So, what does a man like Chang do in his spare time, when he’s not producing remarkable whiskies consumers want to buy? “I watch Netflix,” he says before I can finish asking the question, and then lets out that laugh again. It’s a typically frank and relatable response that comes as a slight shock to us both. Most would – truth or not – say something that made them sound high-brow but not Chang. He continues to say that he’s recently finished the entire box set of 24 (a recommendation by a friend who presumably thought he had a lot of time to kill or difficulty sleeping), a Taiwanese drama, the latest Karate Kid (Cobra Kai) and a series about Japanese history. It’s an eclectic mix and refreshingly honest. As the Komoro project enters its next stage and whisky starts to run from the stills, there will be a lot of pressure on Chang to produce another award-winning single malt but those who know him won’t be concerned. With his formidable knowledge, calm confidence and unwavering integrity, you sense he’s going to do himself – and Dr Jim Swan – proud. Browse all whisky listings or read more Editorial
