After years of holding out, Brunello di Montalcino may finally be inching towards a greater focus on sub-zoning. The innovative Forma project spearheaded by Italian MWs Gabriele Gorelli and Andrea Lonardi – primarily intended to add greater objectivity to the Consorzio’s vintage rating system – has been instrumental, necessitating the assembly of reams of site-based data that have (inevitably) laid bare the great variability within the denomination. With the ever-shifting climate, the site factor apparently top of mind across the denomination is altitude. Montalcino has always traded on a wine that pushes Sangiovese to generous levels of ripeness without – crucially – losing its balance and an unpredictable climate is hardly conducive to such a sensitive balancing act. Pier Giuseppe d’Alessandro of Poggio Antico, where vineyards rise up to 612m above sea level (asl), says ‘altitude does not mean low temperatures but lower temperatures,’ explaining that during August, the vineyards may be 4-5ºC lower than Montalcino’s lowest sites. The critical factor, he says, is the duration of temperature spikes, which tends to be shorter at altitude, helping avoid vine stress. Read more: The Brunello di Montalcino Report 2024 However, there are several dynamics at play: fog in the valleys tends to make nights warmer but mornings cooler, reducing diurnal variation, whereas sites above the fogline warm more quickly in the morning but cool rapidly at night, preserving critical acidity. This slows ripening overall and extends the harvest, sometimes to a dramatic degree – Luciano Ciolfi of Sanlorenzo notes that in the difficult 2024 vintage they had to wait until mid-October. However, Giancarlo Tommasi and Emilio Falsini, director of Tommasi Family Estates and enologist of the group’s Montalcino property Casisano say their breezy, high-altitude sites facilitate more uniform ripening and thus more aromatic complexity. Finally, Riccardo Campinoti of Le Ragnaie, known for its high-altitude single site wines, likes that altitude can help reduce vigour and naturally limit yields. Yet another factor in Brunello di Montalcino is geology. Acidity-preserving stony calcareous soils dominate at higher altitudes, while richer alluvial soils are common lower down, giving altitude pedological as well as climatic significance. In years where the main problem is not intense heat but abundant rainfall, like 2024, the slopes and well-drained stony soils of higher sites can save the vintage. Montalcino collectively affirmed the importance of altitude in 2015 when it first allowed vineyards above 600m asl into the appellation (whether the region might also have set lower limits on altitude remains an open question). Gianni Pignattai of Pietroso, whose vineyards are mostly between 400 and 500m asl, notes that ripening at these heights was frequently challenging even 10-15 years ago but that they are now his least challenging vineyards to manage, as their lower humidity and greater ventilation allow him to use fewer pesticides. One thing made clear by the handy 3D map produced for the Forma project is that most of the wine world’s (including the Italian wine world’s) mental image of Montalcino as a roughly cone-shaped protuberance sloping uninterrupted to the flat plain below might need updating. The northern slope of Brunello di Montalcino is indeed more uniform, with only small bumps like Montosoli breaking up its descent. However, the southern stretch is much more topographically varied, with high-altitude sites running all the way south-southwest from Montalcino town to Sant’Angelo in Colle (once unfairly lumped in with the much lower-lying Sant’Angelo Scalo) and south-southeast nearly to the town of Castelnuovo dell’Abate, both about 7km away as the crow flies. Blends that incorporate at least some high-altitude elements are a snappy riposte to many low-energy bottlings of the mid-2000s Though multi-site blending remains the norm (and with an increasingly unreliable climate, the blenders may eventually have the last laugh) single site wines from high spots, like Campinoti’s Passo del Lume Spento at 621m asl in Ragnaie, some distance south of Montalcino town, are redefining the upper octaves of Brunello. Meanwhile, blends that incorporate at least some (and often several) high-altitude elements are a snappy riposte to many low-energy bottlings of the mid-2000s. Andrea Cortonesi of Uccelliera based his second brand, Voliero – which, unlike Uccelliera, is blended from across the denomination, including Sant’Angelo in Colle – on the notion that high-altitude sites are linked by consistent (and desirable) characteristics. On the other hand, there is also clearly some variability among high-altitude wines. Some, like Campinoti’s, trend delicate, tart-fruited and herbal, with alcohol levels (~13.5%) to match. Contrast this with Poggio Antico’s wines, including I Poggi, from their highest active vineyard at 550-575m asl, which is a potent 15%, though with great tension from its dynamite acidity. Exposure, slope and airflows have great impact at these heights – Sanlorenzo’s vineyards sit southwest of Montalcino at 500 asl in two valleys that face southwest towards the Mediterranean and its warming breezes, but Ciolfi says they recently planted some north-facing land in the same area and have just started to vinify the results. Antonio Michael Zaccheo of Carpineto, where vineyards run from 470-500m asl, believes they are the only ones at that altitude with vineyards fully exposed to the north and slopes up to 30%; they typically harvest over three weeks after valley vineyards, with low sugars and elevated acidity. The challenge is that, with new Brunello plantings frozen since 1997, opportunities to plant higher are limited. Pignattai says though they would like to plant more high-altitude sites, they haven’t found owners willing to sell. D’Alessandro says ‘we do not have higher land to plant because there is no higher land’– Montalcino, unlike Chianti Classico, has no land above 650m asl. However, he is sanguine that with experimental viticultural practices – more dynamic vineyard architecture that permits rapid response to changing conditions – the advantages of higher altitude can be maximised. Giulia Härri, enologist at Mastrojanni, agrees that cultivation techniques are key to altitude’s effectiveness against climate change; she credits their biodynamic viticulture with helping avoid vine stress. While not a silver bullet, altitude is undoubtedly one factor that may help preserve Brunello’s freshness. Montalcino’s best and brightest are harnessing its power in some of the denomination’s most exciting wines where intense aromatics (and sometime generous ripeness) are offset by gravity-defying acidity.

Altitude’s role in the future of Brunello di Montalcino

Steep slopes, high hopes: Altitude’s starring role in the future of Brunello di Montalcino 

Because of the technical demands of its wines, Champagne has often been associated more with the skill of the people and technology behind the bottles than with the land itself. Yet in the 1980s, amid a period in the wine world dominated by industrialisation, a handful of quality-focused grower-producers began championing terroir-driven Champagne, laying the foundation for the nuanced, expressive wines we celebrate today. Thanks to them, the names of Champagne’s grands crus are firmly etched in the minds of today’s connoisseurs. We can now delve even deeper into individual lieux-dits through an ever-expanding array of single-vineyard Champagnes. For decades, Philipponnat’s 1935-initiated Clos des Goisses from Aÿ’s monumental slope stood alone. The modern single-vineyard boom began in 1979 with Krug’s Clos du Mesnil, and the growth since the 1990s has been exponential. Through site-specific Champagnes, we have learned to thirst for such terroirs as Ambonnay Les Crayères, Cramant Le Bâteau, and Le Mesnil-sur-Oger Les Chétillons. The modern single-vineyard boom began in 1979, and the growth since the 1990s has been exponential Elevating the ‘autres crus’ Equally significant is the rise of Champagne’s autres crus, the once-overlooked villages without premier cru or grand cru designation. Montgueux and the Côte des Bar in the south have become particularly dynamic regions. Thanks to vigneron Emmanuel Lassaigne’s work at Jacques Lassaigne, Montgueux’s majestic Chardonnays are in high demand – not only by the major houses, which prize their structured elegance, but by discerning consumers seeking unique expressions. Another quickly rising village is Les Riceys – Champagne’s largest cru, with well over 800ha (1,980 acres) – where Olivier Horiot and Domaine Alexandre Bonnet showcase Pinot Noir’s distinctive power. If the classification were reassessed today, neither of these villages would remain autres crus. Following in the footsteps of the consistently magnificent Cédric Bouchard Roses de Jeanne Champagnes, the list of exciting producers in the Côte des Bar continues to expand, reflecting the subregion’s dynamism. Recently, I’ve been impressed by the bright, transparent non-interventionist style of Domaine de Bichery (Neuville-sur-Seine) and the sheer expressiveness of Clandestin (Landreville). The Champagne septet Chardonnay always remains in fashion in Champagne, but it is thrilling to see more regional expressions emerging. Among the most striking are Ulysse Collin’s single-vineyard wines from the up-and-coming Coteaux du Petit Morin, just south of the Côte des Blancs. The Sézannais and Vitryat regions are establishing themselves strongly, as is Montagne de Reims, which offers a wealth of exceptional Chardonnay sites. One of my personal favourites is Rilly-la-Montagne’s chalky Les Blanches Voies terroir, where both Vilmart & Cie and Huré Frères craft magnificent wines. Meunier, long out of fashion, has enjoyed a remarkable resurgence thanks to the passionate growers of the Vallée de la Marne. Once again in the spotlight through the work of, for example, Tarlant, Jérôme Prévost and Egly-Ouriet, today producers such as Nicolas Maillart, Gounel-Lassalle and Laherte Frères are elevating Meunier to unprecedented heights. Despite this progress, I believe Meunier still has vast untapped potential to reveal. In Champagne’s Pinot Noir heartland of the Grande Vallée de la Marne, houses such as Bollinger and Philipponnat are cementing their authority with a string of pure Pinot Noir releases. But what’s notable today is that the new wave of blancs de noirs is no longer chasing cult benchmarks like Bollinger’s Vieilles Vignes Françaises and Krug’s Clos d’Ambonnay – bottlings famed for their unapologetic richness. Instead, the spotlight is shifting to a fresher, more contemporary interpretation of Pinot Noir. Consider the precision of Nicolas Maillart’s Montchenot or the electric verve of Domaine La Borderie’s De Quoi Te Mêles-Tu?; these are wines embodying a new aesthetic that privileges finesse over power. In a nod to its past, Champagne is tentatively reviving its forgotten heritage grapes Arbane, Petit Meslier, Pinot Blanc and Pinot Gris. Let’s not overstate the trend – plantings of these cépages still account for just 0.4% of the region’s vineyard area, up only a fraction from 0.3% a few years ago – but the trajectory is undeniable: over the past two decades, these varieties have expanded by 45ha, now covering 136ha in total. The south of Champagne has quietly kept the flame alive, where Arbane, Petit Meslier, Pinot Blanc and Pinot Gris continue to offer an unmistakable local accent. Domaine Alexandre Bonnet’s Blanc de Blancs, for instance, is half Pinot Blanc, half Chardonnay. Arbane may remain an infamously meagre producer, yet vignerons such as Laherte Frères see real promise in Petit Meslier, particularly in the era of climate change, thanks to the piercing freshness it brings to the glass. Evolution, not revolution Freshness, rather than ripeness, has become Champagne’s new obsession. With harvests creeping into August and fruit coming in under a blazing sun, the challenge now is to preserve acidity, not to coax maturity. The old orthodoxy of 100% malolactic fermentation is giving way as more producers choose to let a streak of crisp malic acid sharpen their blends. Even the sacred formulas of brut Non-Vintage cuvées are being rewritten. Previously, reserve wines were prized for softening edges and adding richness, but today they are reimagined as a safeguard for vitality. Louis Roederer has gone so far as to reinvent its flagship Non-Vintage, now called Collection, introducing a perpetual reserve stored in gigantic vats – a safeguard of freshness that now defines the wine’s very DNA. Simultaneously, it has evolved from an ‘ageless’ Non-Vintage, with no reference to its base year or disgorgement, into a collectable, complete with edition numbering, like the Jacquesson 700 series or Lanson Création. The moment has finally arrived in Champagne to stop concealing the base year and other technical details and instead to celebrate them with pride. Falling sugar levels and minimal intervention The shift in Champagne’s taste profile goes hand in hand with a steady trimming of dosage. Despite the buzz in sommelier circles and wine-press headlines, the ultra-dry styles remain a statistical footnote: barely 3.6% of exported Champagnes carry less than 6g/l (extra-brut or brut nature). Yet the broader reality is unmistakable: sugar levels are falling fast. Dom Pérignon’s 2015 Vintage, for example, sits at just 4.5g/l. It’s not only prestige cuvées chasing purity; the entire region is recalibrating as even the world’s most popular Champagne, Moët & Chandon Impérial, is dropped down to a record low dosage of 6g/l. The old rationale of softening searing acidity with sugar has lost its purpose. In today’s warmer vintages, the dash of sugar is ‘seasoning’, tempering phenolic bite and extending the wine’s length and deliciousness. Few regions have leaned on sugar as heavily as Champagne. Traditionally, it has been added three times: first to enrich the must for higher alcohol (chaptalisation), then to spark the second fermentation in bottle, and finally as the sweetening dosage. Today, however, the pendulum is swinging towards authenticity, and sugar is a villain there. In a move pioneered by Agrapart in 2007, some vignerons are replacing industrial sugar with preserved grape must from the previous harvest to ignite the second fermentation (or, if bottling later, with the juice of the new season). Since the 2019 vintage, Fabrice Pouillon of Champagne R Pouillon & Fils has gone a step further, crafting his Champagnes entirely without external sugar. Even when dosage is applied, it comes from grape juice itself. It’s a small revolution – one that redefines purity in a region that was once synonymous with sweetness. If the first wave of Champagne’s game-changers sometimes veered into excess with bone-dry bottlings, overpowering oak, and (too) low sulphites, the next generation has found its stride with impressively sound and exciting wines, often achieved through minimal-intervention techniques. With offerings that are precise, vibrant and true to site, producers such as Jules Brochet and Domaine de Bichery exemplify this new, confident minimalism. For those chasing innovation, Famille Moussé is a must-visit. Cédric Moussé, a true inventive force, equips his ultra-sustainable winery with every tool and gadget imaginable. In the village of Cuisles, he has even launched Champagne’s first cooperative to cultivate vineyards with the aid of robots. For a greener future At the same time, Champagne is getting greener. Comité Champagne is pushing for a collective effort, while the grandes maisons are turning corporate ambition into vineyard action. The EPI Group trio (Piper-Heidsieck, Charles Heidsieck and Rare Champagne) were the first in the region to achieve B Corp certification. Pernod Ricard’s houses – GH Mumm and Perrier-Jouët – are championing regenerative viticulture. Ruinart, the sustainability flagship of LVMH’s Champagne empire, houses a landmark vitiforestry project across its vast Taissy holdings. But the movement is not confined to big brands – for example, Aurélien Lurquin and Domaine La Borderie are doing impressive work. And while small houses remain Champagne’s most visible champions of organics and biodynamics, it is Louis Roederer that has rewritten the scale: with 130ha now certified organic, it alone represents almost 6% of Champagne’s total organically certified vineyard area (2,240ha as of the end of 2024). As transportation makes up the lion’s share of Champagne’s carbon footprint, producers are finally looking at rationalising their packaging. Cédric Moussé recently developed the lightest bottle so far, which will enter the market in two years’ time. He also transitioned from traditional metal capsules to recyclable paper ones, which reportedly have a carbon footprint just 20% of that of aluminium. Ruinart deserves high praise for its Second Skin bottle cover, moulded to the contours of the bottle. Fully recyclable and made from 99% paper, the case is marketed as nine times lighter than its predecessor. Beyond the sustainability gains, it elegantly addresses a quality concern: Ruinart’s hugely popular Non-Vintage Blanc de Blancs in clear glass is now protected from light-strike – a phenomenon that can rapidly degrade Champagne yet is overlooked by consumers and the trade alike. Moving away from clear glass is not just a matter of quality, it is also a sustainability imperative, as these bottles require new, rather than recycled, glass for production.The Champagne landscape has never been more thrilling. Beyond the classic offerings, you’ll find late-disgorged gems, rosé de macération, clos and other site-specific expressions; perpetual reserves; and cuvées aged in a multitude of vessels from oak and sandstone to glass and clay amphorae, each promising a fresh take on the region’s tradition. Today’s younger buyers crave brands that marry luxury with ethics, and Champagne is responding. The rules are changing, the classics are evolving, and the next sip could redefine everything you thought you knew. Browse all Champagne listings

Terroir vision: the future of Champagne

The old adage about necessity being the mother of invention springs readily to mind when you hear the story of Jean-Luc Pasquet. In 1970, he took over a Cognac vineyard at Chez Ferchaud, a few kilometres southwest of Châteauneuf-sur-Charente, from his uncle Albert Brisson. Things got off to an excellent start. The weather was glorious and the 1970 harvest was abundant – ideal when your business model is predicated on selling to the big Cognac houses that dominate the industry. Life, in other words, was good. But then came the oil crisis and a downturn that badly affected trade in Cognac, prompting Jean-Luc to think again. Amy Pasquet, his daughter-in-law, takes up the story. ‘He said, “I have some really unique terroir; I’m going to make my own label,”’ she explains. And so, in 1977, Cognac Jean-Luc Pasquet was born. Soon, Jean-Luc’s Cognacs were picked out and praised by a German journalist, prompting interest from Germany, Sweden and the UK – and the company, today run by Amy and her husband, Jean-Luc’s son Jean, hasn’t looked back since. Cognac is replete with individuals like Jean-Luc Pasquet. Often they are the unseen drones of a multibillion-euro industry, toiling in vineyard, winery, distillery and cellar to fuel the engines of the quartet of titans that dominate global trade: Hennessy, Martell, Rémy Martin and Courvoisier. But to those in the know, they shine a new and very different light on a corner of rural France that continues to produce the finest brandy in the world. ‘Cognac is so artisanal when you go outside of [the big four houses],’ says Amy. ‘I think a lot of people coming from the world of Scotch and other spirits think it’s kind of boring. But you have 250 artisanal brands with their own vines – it’s a joy to explore.’ Cognac is so artisanal when you go outside of the big four houses – it’s a joy to explore – Amy Pasquet As well as being the source of high-quality, excellent-value and sometimes downright quirky Cognacs, these small producers provide enthusiasts with no shortage of fascinating rabbit holes of flavour and provenance down which they can happily vanish. They are the antithesis of the blended VS, VSOP and XO bottlings that dominate shelves and back bars from Shanghai to San Francisco. Jean-Luc Pasquet’s vineyards – 15ha (37 acres) now, spanning the Grande and Petite Champagne crus – are all farmed organically, which is no small feat in this Atlantic-influenced, notoriously humid part of western France. The Pasquets rely heavily on weather stations and apps to ensure the vines get the right treatment at the right time. ‘Our two vineyards are only 5km [3 miles] apart but they have very different microclimates,’ says Amy. As if organics didn’t make life difficult enough, the Pasquets are also huge fans of Folle Blanche, the grape variety that dominated the pre-phylloxera Cognac vineyards but has fallen heavily out of favour since, on account of being fiendishly difficult to farm. (About 98% of Cognac plantings are now Ugni Blanc.) An annual JL Pasquet bottling of a 10-year-old cask of Folle Blanche is a perennial highlight. Jean-Luc Pasquet set up his business as a négociant; this meant he could bottle other people’s Cognacs, as well as his own, though he had no need to do so in the early years. In 2018, however, demand was such that the company ran out of its own aged stock. What resulted was L’Esprit de Famille, later renamed Trésors de Famille single-cask bottlings of Cognacs produced by small grower-distillers – known as bouilleurs de cru. It began with Le Cognac de Bernadette, a 1974 Cognac from Bouteville in Grande Champagne, and it has continued with bottlings of Le Cognac de Paul, Claude and André-all namechecking the producers in question. ‘For me, all of these vintners are the unsung heroes of Cognac’, says Amy Pasquet. ‘They’re selling to big houses, making really fine products and never getting any credit.’ It’s one thing to know that there are many dozens of small producers out there, but quite another to be able to track down their Cognacs, short of conducting your own painstaking tour, cellar door by cellar door, of the Charente region. Here specialist retailers such as The Whisky Exchange are a great place to start, unlike the multiples, they take the trouble and have the space to stock a much broader range of smaller producers and interesting bottles. If this were Scotch whisky, of course, enthusiasts on a quest for obscure single malts would turn to independent bottlers but that concept is far less common in Cognac. The superb selection offered by David Baker’s Hermitage Cognacs has long been an exception to this rule, as are the releases of Cognac Sponge from bottler Decadent Drinks, then there’s Through The Grapevine (TTG), an independent bottling offshoot of French retailer La Maison du Whisky in association with Italian importer Velier. Now managed by Antoine Bouchard, TTG was revamped two years ago, with Bouchard setting out to create a rolling annual release programme of single-cask Cognacs spanning from the 1930s to the 1990s in colour-coded bottles designating the region’s different crus. Unlike most Cognac operators, TTG encourages its partners to minimise any reduction in alcohol, everything is geared to reject homogeneity. ‘The idea of TTG is to unearth the “hidden gems” of the region, not to go towards the big four like Hennessy – although they’re doing a great job, don’t get me wrong’, says Bouchard. ‘We want to emphasise that the big brands are blending subregions, thus erasing, in a way, the identity of the grape and the distillate. Instead, we want to focus on how the soil influences the final product.’ The result, in the most recent round of TTG releases, is an eclectic selection of idiosyncratic Cognacs. There’s everything from a benchmark Grande Champagne from Jean Fillioux (Lot 63, signifying a blend of mainly 1963 eaux de vie with a little 1965) to a totally out-of-the-box Château de Beaulon 1988 Fins Bois. Created by the remarkable Christian Thomas in the far south of the region, close to the Gironde Estuary, it’s bottled at a muscular 55.2% ABV and eschews the ubiquitous Ugni Blanc for a unique blend of obscure grape varieties: Colombard, Montils, Folle Blanche and Folignan. If Beaulon waves the flag for Fins Bois, TTG’s remarkable Mauxion 45 (yes, 45 as in 1945) does the same for the often overlooked Bons Bois cru – although it’s sadly out of stock now. ‘It’s really about showing that there is no subregion inherently better than another’, says Bouchard. ‘To me, Bons Bois Cognacs are amazing and it’s such a shame that Grande Champagne is seen as the greatest cru.’ While a terroir-focused, provenance-rich approach to Cognac remains predominantly the preserve of smaller operators, others are taking note. Delamain – a specialist in long-aged Cognacs of XO grade and above – is now managing its own Grande Champagne vineyard, as is Hine. And Frapin, with its 240ha (600-acre) estate at Château de Fontpinot, has always been rooted in the soil surrounding its vines. Drinkers around the globe are changing and Cognac – ever so slowly – is changing with them The largest operators remain predominantly focused on their core VS, VSOP and XO blends, but the philosophy is shifting here, too. ‘For me, the approach for Cognac has to be much more precise, like the grands crus we have for our wine regions in France,’ says Baptiste Loiseau, cellar master at Rémy Martin. ‘We see more and more small producers going with much more information on the label.’ In 2022, Loiseau released Rémy Martin L’Étape in France, a 7,000-bottle release that blended 14 eaux de vie sourced from growers across Grande and Petite Champagne who have achieved HVE (High Environmental Value) certification – complete with a paper wrapper featuring grower testimonials, a map and a QR code for more information. Rémy Martin Tercet, meanwhile, highlights the respective roles of wine grower, distiller and blender. At Martell, cellar master Christophe Valtaud has created the Martell Single Cru Collection – a six-strong range of Cognacs including three Discovery Edition products (Petite Champagne, Borderies, Fins Bois), two Aged Editions (Grande Champagne XO, Borderies XXO) and one Vintage Edition (Borderies 1999). As well as showcasing Martell’s signature Borderies origin, these Cognacs challenge preconceptions, particularly the younger Discovery Edition trio. ‘Before tasting, people think that the Petite Champagne will be the best, but the best Cognac at this stage and the biggest pleasure to drink is the Fins Bois,’ explains Valtaud. ‘Fins Bois eaux de vie find balance more quickly than Petite Champagne, which is more spicy and a little bit less easy to drink. People think that Fins Bois and Bons Bois are not the best, but it’s not always the case.’ Drinkers around the globe are changing and Cognac – ever so slowly – is changing with them. ‘In England, America and China, I see the new generation wanting to know what the size of the cask is, or how many bottles we produced in this special vintage,’ says Delamain cellar master Charles Braastad. ‘I think that this is our time; the world has become more informed and more interested. People just want to know what it is that they are drinking.’

Reimagining Cognac from the ground up

Will Berliner says he didn’t drink wine until he was in his 50s. There might have been the odd bottle of Thunderbird in his teens – he’s a New Yorker by birth – but that was all. ‘All I knew was that white wine was for girls and red wine was for guys. I never drank it.’ So it’s remarkable that now, in his 70s (he looks a decade younger), he’s producing a wine that has been lauded since its first vintage in 2010. Cloudburst, from Margaret River in Western Australia, has been described as ‘otherworldly and memorable’ by Matthew Jukes; ‘fearless and uncompromising’ (Huon Hooke); and ‘a gorgeous wine’ (Jane Anson). It joined the mighty John Riddoch and The Armagh as the first Australian wines on the Bordeaux Place. ‘Will works in ways that are completely different to the mainstream. He’s doing amazing things and his wines are excellent,’ Andrew Caillard MW, author of The Australian Ark, told me. In minimalist, etched glass (screwcaps on both red and white), Cloudburst wines sell for between £130 and £200 per bottle. It’s one of the most expensive Margaret River wines but given that it’s vanishingly rare – Berliner makes about 250 cases of Chardonnay, 200 of Cabernet Sauvignon and 50 of Malbec (it can be much lower – there was less than half that in 2022) – that’s pretty good value. We meet downstairs at Hedonism in London’s Berkeley Square. ‘There he is!’ Berliner says, as if it’s me who’s the celebrity. He’s compact, fit-looking and energetic; from the moment we sit down, he barely draws breath in his urge tell the story of what he calls ‘the most improbable project ever.’ A restless entrepreneur who grew up in New York and moved to New England, Berliner has run a Patagonia-style sustainable clothing business, a Whole Foods-style grocery and a futon business. He’s made schlocky feature films (‘they weren’t super successful’). He built a company, sold it, built another and so on. In 2003, he and his wife Alison Jobson (who is Australian) bought 100ha at Wilyabrup in Margaret River because they loved it and wanted to retire there. The estate was virgin land (though Wilyabrup is full of illustrious estates: Pierro, Moss Wood, Cullen, Vasse Felix) and he says he had no intention of making wine; he might plant a row or two to sell the grapes. Then he caught the bug. A friend – ‘a big New York restaurateur’ – taught him to taste and he got ‘turned on’ to Bordeaux (‘only the Left Bank’). He put himself through a night-school degree in viticulture and enology at UC Davis, and, in 2005, planted a pocket-handkerchief sized plot, one-fifth of a hectare of Cabernet Sauvignon. He was mentored at first by Stuart Watson and his father David, founder of Woodlands Wines in Wilyabrup. ‘I’m ever grateful to him. He’s brilliant and open-minded,’ Berliner says, before adding (with characteristic modesty), ‘but it took someone with my disposition and background to take it to this level.’He now makes the wines himself, from a slightly bigger vineyard – 1.25ha of Cabernet Sauvignon, Chardonnay and 10% Malbec, from which he makes hobbyist amounts of single-vineyard bottlings.When he pours the Chardonnay, I’m expecting something pretty good but somehow not so delicate (it’s not an adjective I’d use for the stocky New Yorker sitting opposite me). There is nothing showy about Cloudburst. The Cabernet is perfumed and delicately tannin-ed, the Chardonnay restrained. They are complex, structured and elegant, the fine work of someone striving for that holy grail of sense-of-place. It took someone with my disposition and background to take it to this level You meet winemakers like this on every continent and each has their own way of articulating this elusive ambition. For Berliner, it’s a Gaia-like concept of oneness with the earth. ‘My life energy has always been about being in nature,’ he says. Cloudburst, he recently told a magazine, ‘is driven by very different considerations than those of my neighbours. It is cultivated differently from any other vineyard in the world.’ Over the years, he’s said a few things that might be thought foolhardy for a fast-talking American in Australia. When I put this to him, he looks for a moment like a 14-year-old unfairly accused of pinching his dad’s cigarettes. ‘I don’t know what you’re referring to,’ he says. How about the idea you’re working to a different rhythm to everyone else? This gets us into a discussion of tall-poppy syndrome, the peculiarly Aussie mechanism by which anyone who puts on airs gets quickly cut down to size. ‘I have been tall-poppied,’ he admits. Some people in Margaret River were threatened by him, he goes on. ‘It’s a normal human characteristic for people to react in a certain way. I understand that, and part of me is very forgiving. But others realise there is great value in having an estate that’s absolutely pure and so small that it demonstrates something. And what we demonstrate is instructive for those who are willing to take a moment and listen.’ And Berliner’s neighbours seem to have got over his tall-poppyness. ‘Will nurtures the wine with his unique personality and it eventuates in Cloudburst as a unique expression of Margaret River,’ Virginia Willcox, head winemaker at Vasse Felix, told me by email. Were his neighbours annoyed by some of his comments? ‘I would hope that all growers have some different considerations to their neighbours. Will is unusually connected to his property and does things his way based on what he feels his plants require.’ The most critical I’ve heard is an off-the-record comment that ‘he’s not a team player.’His farming methods – own-rooted, dry-grown vines, no tilling, wild-yeast ferment in open barrels, no racking or stirring – are not that unusual for a modern artisan wine, but he was ahead of the game when he planted. No-dig mulching, for example, wasn’t that much in vogue in 2005. ‘I did nothing to the soil before I planted. I put down good quality cover crops but basically all I did was poke holes in the ground and stick [in the root]. And sometimes that worked, sometimes you’d have a root that made it on top of a rock and dried up. So there’s a differential from gnarly vines to very skinny vines.’ I care about making a little bit of something extraordinary Many gifted winemakers find it difficult to explain what they are trying to do. Some take recourse in mystical hocus-pocus, others skewer their audience with opaque science. Anyone who ever listened to the late Serge Hochar of Château Musar explaining his white wines will know what I mean.I imagine he got into wine in the same way he got into all his other ventures: learn the subject and do it better than anyone else. But if it had been just that, he’d be farming a lot more than 1.25ha now. He insists he’s not in it for the money, and I believe him. ‘This little bit takes all of me. I don’t give a shit about scaling. I care about making a little bit of something extraordinary. And the thing that has distinguished us, for our customers, is that they get a piece of something that tastes extraordinary.’And so he reaches for a bottle and pours me a glass that is – yes – extraordinary.

The most improbable project ever:Will Berliner on Cloudburst

‘The most improbable project ever’: Will Berliner on Cloudburst

The key words that spring to mind when describing Clos des Papes are ‘elegance’ and ‘consistency’. Whilst the common perception of Châteauneuf-du-Pape is (usually correctly) one of power and richness, Clos des Papes possesses a restraint and an almost Burgundian character that very few other wines from the region do.  The consistency of Clos des Papes wines is largely thanks to the stability behind the scenes, and that over the decades there have only been minor tweaks in the approach and philosophy of this great domaine in the Southern Rhône. Winemaker Vincent Avril took over from his father Paul in 1987 and is currently on his 38th vintage. ‘I have changed very little of what my father did. The biggest change has been a deeper focus in the vineyard, as I would say that 80% of the work is done in the vineyard itself. And, of course, the soils are key: we have 24 different plots and 24 different soil types, which is a blessing.’ Clos des Papes possesses a restraint and an almost Burgundian character There has only ever been one red and one white cuvée produced here, with Avril showing no interest in following the trend for cuvée speciale, which all too often can be even more powerful and weightier than the traditional cuvées. One of the more significant changes has been the changing grape mix in the vineyard, with less Grenache and more Mourvèdre. ‘Chateauneuf is the most northern outpost for Mourvèdre in France, and it gives a brightness and wildness and spice to the wines in their youth. We now have around 55% Grenache, 30% Mourvèdre, 10% Syrah and the balance is Counoise and Cinsault.’ According to Avril, the most important thing for his wines is tannin and phenolic maturity. He never picks on sugar content but on tannin ripeness. ‘If your tannins aren’t ripe then you will feel the alcohol far more. If the tannins are ripe then you will automatically have better balance and alcohol integration. I also believe that the quality of tannins is fundamental for the ability to age. For that reason, I also only use old foudres and never any new oak; I don’t want oak tannins in the wine, I want to taste the grapes, the soil and the place.’ At Clos des Papes, the reds are always co-fermented with two varieties together. When I ask what this brings, Avril explains that ‘the wines are just more complete when fermented and blended from the beginning. My father and I did trials every year of single ferments and co-ferments and then we tasted the results; we always chose the co-ferments, they are deeper and more complex.’ As this vertical tasting demonstrated, they are certainly wines with profundity, complexity and an incredible capacity for ageing. On the issue of climate change, it was interesting to hear Avril’s thoughts on the impact it has had on Clos des Papes over the decades. ‘This really hasn’t had a huge amount of difference, especially not compared to places like Burgundy. We are now only harvesting on average two to three days earlier than we were 30-40 years ago. But what we have are more peaks, so we may see a huge downpour of 100mm of rain in an hour, and we certainly see less rainfall in summer. So it is more extremes but not necessarily warming.’ One effect on the winemaking as a result of these changes, however, was the decision made in 1992 to totally de-stem the fruit. With less rain in the summer, the stems do not get fully ripe and therefore would potentially add a greenness to the wines, thus undoing all the hard work of the judicious tannin management. The white wines are somewhat atypical in terms of Châteauneuf for several reasons. Firstly, they are a blend of six varieties, all contributing in different ways. Grenache and Rousanne give richness but can lack acid, Clairette and Picardin add elegance and the freshness comes from Bourboulenc and Picpoul. Secondly there is no oak or malolactic fermentation and the wines are bottled very early, normally in February following harvest. For Avril, the whites nearly always follow the same maturity: ‘The young wines show peach, anis, white flowers, grapefruit and a salinity. As they age, they become more mineral and almost show a Riesling like petrol note. And then heading towards 20 years we see honey, dried apricots and quince appear.’ These are whites that do have a freshness that many other whites from the appellation do not have, yet never at the expense of the textural richness that is integral to their identity. I consider Clos des Papes wines to be extremely good value for money The tasting demonstrated perfectly the trajectory that Clos des Papes wines tend to follow as they age. In their youth, they offer very attractive drinking for two to three or so years after bottling with primary fruit and a suave feel as demonstrated by the 2021, 2022 and 2023. The wines then tend to shut down in bottle, as seen with the 2019, which whilst having a spellbinding nose was quite tight on the palate but with such balance. The 2016 was still somewhat tight but just beginning to unfurl and open up, while the 2010 was drinking just beautifully yet clearly with great potential to develop further. The coup du coeur for me was the quite magnificent 2005, which still maintains such tannic structure and grip but with beautiful fruit, texture and minerality. Again, this seemed to be dipping into a quieter phase as well and I expect it will age gracefully for another 20 years. Clos des Papes is a wine that should be on every Rhône lover’s radar. Firstly, I consider them to be extremely good value for money. They are wines that offer so much pleasure over such a long period of time yet can still be enjoyed in their youth. Each vintage really does speak of the year yet with the hallmark of Clos des Papes, as Avril explains, ‘I compare my job to that of a painter. At the beginning of the year, I get a blank canvas and the weather is what gives me the colours with which to paint the best picture possible. Each year the resulting painting will be different but always with the same signature beneath.’ Vincent Avril is a man that makes it all sound so simple, yet the wines are anything but and offer incredible complexity, elegance and refinement.

Clos des Papes 2005-2023

Chianti Classico’s Gran Selezione serves as a fascinating case study in how to elevate (or, arguably, re-elevate) a region’s wines to fine-wine status. From a mere 33 producers when the category was first introduced ten years ago to 169 today – making 213 Gran Selezione wines between them – the category has seen explosive growth to 5% of total regional production, giving the region an almost unprecedented glow-up. It hasn’t always been a smooth road: ‘the Gran Selezione had a rather complex birth,’ says Dr. Marco Pallanti of Castello di Ama – who was president of the Chianti Classico Consorzio when the Gran Selezione was proposed and approved. He recounts that many producers wanted to participate in the drafting; what ultimately emerged was a kind of parcellation carried out by the producer and not by external bodies. "The Gran Selezione category has seen explosive growth" On paper, one might argue the requirements were moderate: the wines had to be estate-grown and -produced, aged for slightly longer (30 months, of which three had to be in bottle) with slightly higher alcohol and dry extract; there weren’t geographic requirements above and beyond the stipulations of the DOCG. The wines themselves, though, were typically far more ambitious than the above would imply, often made from single sites and treated to costly, oak-laden ageing regimens. However, the last several years, and 2023 in particular, have brought about some shifts – whether through regulations or market preferences. Below, I’ve explained some factors that may prove pivotal for the category as it moves ambitiously into its second decade. A new dawn for site specificity The most talked-about addition to the Gran Selezione has been the UGA or Unità Geografiche Aggiuntive, a broad division of this large region into 11 roughly commune-scale sub-regions (some of which are co-extensive with actual communes, like Radda, Gaiole and Castellina, and the rest of which are not). These are applicable exclusively to Gran Selezione wines and, as of July 2023, may appear on front labels. During my travels in the region immediately before the formal approval in 2023, many producers expressed a keen interest in this shift, though the level of that interest naturally varied with the prestige (and meaningfulness) of the UGA. Lamole and Panzano, both carved out of Greve commune, are two UGAs with clearly defined identities and aren’t burdened with the awkwardness of an unpronounceable name (my apologies to Vagliagli), and hence seem much more likely to be coming soon to a shop near you. Nearly monovarietal but not quite Another 2023 shift has been the increase in Sangiovese from 80% to 90% of the blend. Though a seemingly minor shift, there are those who view this as yet another step away from the historical ‘formula’ of Barone Ricasoli (the historical authenticity or at least intent of which is debated), which included white Malvasia grapes along with Sangiovese and Canaiolo. However, the vast majority of Gran Selezione wines reviewed in the Chianti Classico Report are already made up of 100% Sangiovese (not least Ricasoli itself). It is clear that the Sangiovese purists – perhaps originally inspired by the success of the varietal Sangiovese Supertuscans – have nearly won the day anyway. Banishing the internationals A possibly more controversial move is the exclusion of international varieties like Cabernet Sauvignon, Merlot and, to a lesser extent, Syrah, from the blend. These have – as Pallanti points out – made a home in Tuscany for at least the last 40 years and, in his view, end up ‘Chiantiggiato’ or ‘Chiantified’ by the environment (a viewpoint that aligns with my own observation during my MW studies that Tuscany somehow turns everything into Sangiovese). Pallanti’s own iconic Gran Selezione wines incorporate some Merlot, along with the native Malvasia Nera, as does the gorgeous Don Tommaso from Principe Corsini. Among the vanishingly few other non-varietal Gran Selezione wines in our tasting, the blending partners were largely natives: highly pigmented, plush Colorino seems to outrank the more historical Canaiolo, perhaps representing the last remnants of producers’ drive to make Sangiovese darker than it naturally wants to be. Meanwhile, native grapes are playing a bigger role in the Riservas and especially Annatas, where they add some richness or complexity. A new Gran Selezione style Chianti Classico has the great advantage of already being what the contemporary fine-wine market wants: translucent, elegant and low in invasive oak aromas. Revisiting the early 2010’s Gran Selezione wines is a reminder of the sheer ambition that accompanied these first strides towards fine-winehood. During a vertical tasting of their Gran Selezione, Castello di Albola’s Alessandro Gallo charted their change in style from plump and barrique-polished to something leaner and racier. The wines of today are not quite the dainty, low-alcohol featherweights of last century (most are about 14% on average, some reaching a Brunello-like 15%), but most have a luminescence and lyricism that make this one of the country’s most exciting categories to watch.

Despite a complicated birth, Chianti Classico's Gran Selezione category is elevating more of the region's wines to fine-wine status than ever. Written for Club Oenologique in 2024, Sarah Heller MW picks out some of the key factors for the future of Gran Selezione wine .

Chianti Classico’s Gran Selezione gets a glow-up

What springs to mind when you think of Bordeaux? Probably châteaux the size of medieval palaces, formal dinners, and rows and rows of pristine vines, neatly manicured rose bushes the only other signs of plant life. What you’re unlikely to be imagining are cow horns stuffed with manure buried in the ground, or horse-drawn ploughs churning through earthworm-rich soil. ‘In the past, in Bordeaux, you were scared to say you were growing biodynamically,’ says Corinne Comme, who manages 10ha of biodynamic vines at Château du Champ des Treilles in Entre-Deux-Mers with her husband Jean-Michel. ‘Now it’s trendy.’ An engineer and geologist, Jean-Michel Comme was behind the first transition of a grand cru classé estate on Bordeaux’s Left Bank to biodynamics. Although he and Corinne first came across the concept in the mid-1990s, he didn’t begin to advocate for the approach at Château Pontet-Canet in Pauillac until the early 2000s. ‘Corinne was scared,’ he recalls. ‘She thought they would fire me.’ "Behind the more esoteric elements is a series of principles that have been shown to improve soil health and vine strength" Originally laid out in a series of lectures by Austrian philosopher, scientist and social reformer Rudolf Steiner in 1924, biodynamic farming emerged as a holistic approach to agriculture before quickly evolving into formal certification movements. At its core, biodynamic farming centres on soil health and biodiversity; most distinctively, it operates according to the lunar calendar, with practitioners timing agricultural activities around specific ‘fruit days’, ‘root days’, ‘leaf days’ and ‘flower days’ to align with cosmic rhythms believed to influence plant growth and agricultural processes. For many in Bordeaux – Jean-Michel Comme included – this all sounded a bit wacky. ‘I was young, full of expectations about chemistry; the way biodynamics was presented was so remote that I felt it was crazy,’ Comme says. ‘But with experience, we did change our minds.’ Why? Because behind the more esoteric elements is a series of principles that have been shown to improve soil health and vine strength. In vineyards, biodynamic farming means specific practices such as hand-harvesting, using natural composts made with specific herbal and mineral preparations, avoiding chemical fertilisers and pesticides, and treating the entire vineyard as a self-sustaining ecosystem. In the cellar, there’s an emphasis on minimal intervention, using native yeasts, avoiding commercial additives, keeping sulphur use to under 70ppm, and employing gentle pressing and ageing techniques that respect the wine’s natural development. While biodynamics took root in regions like the Loire and Burgundy in the 1990s, biodynamic winemaking in Bordeaux largely began in the new millennium, with just two early St-Emilion exceptions: Château Meylet, which has been practising it since 1987, and Château Fonroque, experimenting since 1995 with direction from Loire legend Nicolas Joly. This delay largely stemmed from two factors. First, Bordeaux’s humid maritime climate means that vines are especially vulnerable to both downy and powdery mildew, making the avoidance of synthetic fungicides a risky business. Second, large châteaux with multimillioneuro operations were reluctant to abandon the technological viticulture and winemaking that had built their global reputations in the first place. Comme, however, was convinced of the virtues of biodynamics. He began by seeking the assistance of François Bouchet. The Loire Valley winemaker was one of the first in France to pioneer biodynamics, also consulting for Domaine de la Romanée-Conti, Domaine Leroy and Domaine Leflaive in Burgundy. Bouchet guided the transition to biodynamics at Comme’s Château du Champ des Treilles; then, he persuaded Château Pontet-Canet owner Alfred Tesseron of its merits. In 2004, it was trialled on 15ha (about 20% of the estate’s total growing area) of the fifth growth at which Comme was also technical director. A severe mildew outbreak in 2007 led to the use of pesticides, undoing three years of progress, but it then became a crucial lesson that strengthened their long-term commitment to biodynamics. ‘They believed the fruit had more expression, more brightness,’ says the current technical director at Pontet-Canet, Mathieu Bessonnet, who reveals that they converted the whole of the growing area soon after. ‘It’s obviously much more difficult, time-consuming and expensive, so it was very risky,’ he adds. Since then, biodynamic farming has become a significant and growing practice across different classed growths in the region, with some of the most prestigious estates – such as Château Latour and Château Palmer – adopting biodynamic methods (the latter certified). ‘The link between the wines and the place where the fruit came from had become less and less obvious,’ says Château Palmer’s technical director Thomas Duroux, commenting on the region’s turn to the trend. He notes that, since the noughties, many have adopted organic practices in a bid to reverse this perceived drop in terroir definition. ‘Biodynamics is, in a way, the same story as organic farming, but with a larger vision,’ he adds. This shared perspective has led to more cooperation between practitioners. Every spring, the Médoc branch of the Biodynamic Agriculture Movement gathers at Château Ferrière. After unearthing a thousand manure-filled cow horns and replacing them with silica-filled ones (a process reversed in autumn to produce preparations 500 and 501, required for Demeter certification), participants share wines and gardengrown salads. The humus removed from the cow horns is stored in a cold, damp facility and made available to members. ‘We do that for free,’ says Claire Lurton, owner of Château Ferrière. ‘It’s a community.’ Though ‘community’ might be too strong a word for some, these gatherings symbolise a deepening professional exchange that has emerged among estates of all sizes through the practice of biodynamic winemaking. In fact, the shift among the classed growths has happened at the same time as these practices have been adopted by smaller growers arriving in the region. Christophe Landry of Château des Graviers, for example, returned to Arsac in the 1990s and began practising biodynamics around the same time as Comme at Pontet-Canet. He’s consulted for the Lurton estates and other properties. Originally from Minervois in Languedoc, Michel Théron established Clos du Jaugueyron nearby and has been certified biodynamic since 2008, while Laurence Alias and Pascale Choime – who are both from southwest France – established Closerie des Moussis, a patchwork of sites across 2ha, including a 170-year-old pre-phylloxera plot leased from Théron. On the Right Bank, other producers began switching lanes even earlier. Le Puy, owned by the Amoreau family, began practising in 1998, with certification since 2013, and Château Gombaude-Guillot in Pomerol has been certified biodynamic since 2006. While larger estates like Latour and Palmer collaborate on issues like mildew, smaller producers tend to engage more with one another. Shared biodynamic practices, however, are definitely helping to break down barriers. For example, Château Haut-Bages Libéral maintains regular communication with its neighbours at Château Latour, and the son of Théron at Clos du Jaugueyron interned at Château Palmer for two months. Can we speak of a unity of praxis? Not exactly. There is considerable variation in which aspects of biodynamics winemakers emphasise, regardless of estate size. The primary aim across the board is achieving living soil with rich biodiversity to promote deep-rooted vines. In pursuit of this, some winemakers emphasise tree growing or cover cropping (like Haut-Bages Libéral, which also recently planted a variety of local and fruit trees). Others, such as Le Puy, let nature take its course, allowing a diverse array of plants and flowers to sprout from the earth. Whether certified or not, biodynamic practitioners throughout Bordeaux use homeopathic treatments like nettle teas for the vines – they are believed to stimulate soil health, enhance plant immunity and improve nutrient uptake. More important than any of this, however, is the concept of energy. How can the energy of the plant be retained as its raw material transforms into wine? Every winemaker I visited was at least intrigued by the concept – and most were captivated. After a few days in the sometimes eerily flat Médoc, I drive through the verdant hills of St-Emilion to Le Puy, arriving with a raised spirit. Standing before a 5,000-year-old Celtic cromlech, Harold Langlais, the estate’s director, tells me, ‘Le Puy is a place of energy and life,’ pointing to its deep history as an intersection of water springs. At modern-day Le Puy, this philosophy extends from the vines to the cellar. Indeed, many others I speak to express that, since adopting biodynamics, the most striking change in their wines has been an increase in ‘energy’. It’s a term without a precise definition, but according to Château Palmer’s makers, something shifted with the 2015 vintage, the second year after full conversion. ‘You cannot measure it,’ Thomas Duroux says. ‘You can just feel it.’ At Château Durfort-Vivens, where the vineyard was operating under biodynamic principles by 2013 (with full conversion by 2016), owner Gonzague Lurton recalls the 2014 vintage as ‘the first where you really feel the energy of biodynamics’. It’s tactile and warming, with a sophisticated grip and charm. ‘It’s what I love – the linearity of tannins, never weak from start to finish. With many of the estates I visited, their wines showed an immediate appeal, vibrant even in their youth. Is energy just another way of describing freshness? Laurence Alias at Closerie des Moussis trained as an agricultural engineer; for her, energy and vitality are tied to the physical properties of grapes grown biodynamically. ‘We have more acidity, that’s an analytic fact,’ she tells me, standing in front of a newly acquired plot of vines bordered by forest. It might be romantic to think of energy as something ineffable, but it’s also rooted in what remains within the grapes. ‘Our idea of energy is based more on Einstein than Steiner,’ Langlais later qualifies. ‘Energy is matter.’ Biodynamic winemaking in Bordeaux: five to follow Château Pontet-Canet At the 55ha Pontet-Canet estate in Pauillac, an immensely smooth operation is palpable. Winemakers here have spent almost two decades honing their biodynamic craft, continually moving towards a goal of self-sufficiency for the estate. Sturdy Comtois horses, introduced in 2008, now work half the vineyard, preventing soil compaction. Vineyards are sprayed over a single day using compost and herbal teas produced from plants grown in and around the property and processed in the state-of-the-art infusion room. Biodiversity-boosting fruit trees and hedges have been planted. The estate even employs a carpenter who repurposes wood from vats used on the property. Ageing involves custom-made wooden eggs and qvevri-style amphorae, with no fining and minimal filtration. The result? A Pauillac with untypical levels of energy and minerality, and a plush, velvety texture. But it’s more than that – according to Bessonnet, thanks to a low-intervention approach across the board, ‘you can really feel the soil.’ Château Palmer Thomas Duroux’s conviction in biodynamics is based in what he calls a ‘holistic vision’. ‘We started to see the entire place as a living organism,’ he says of Château Palmer, one of the most storied and historically significant third-growth estates in Bordeaux. When converting (a process that started in 2009), the Margaux estate was initially guided by François Bouchet’s son Matthieu, but now it follows its own evolving philosophy, integrating cover crops, animals for fertilisation and estate-grown vegetables and meat. ‘It’s just going back to agricultural common sense,’ Duroux says. ‘That was the way to grow anything before World War II.’ This respect for nature results in wines that are deeply tied to their terroir. ‘If I had to describe the wines how they are today, compared to how they were before, I’ll just say that it’s not a revolution, but we have the feeling that the wines have a better identity,’ says Duroux. He likens biodynamics to restoring an old painting: ‘Suddenly, you see small details that you were not able to see because of the dust.’ The estate uses stainless-steel vats for fermentation and temperature-controlled rooms for barrel-ageing, combined with nativeyeast and low-sulphur winemaking, to produce its esteemed Alter Ego and Château Palmer cuvées; both have been increasingly celebrated among critics and drinkers since the turn to biodynamics. ‘We just think it does help to go a little bit further in the interpretation of the place,’ says Duroux. Château Durfort-Vivens Standing over a rustic sorting table explaining how it used to work, Gonzague Lurton is visibly passionate about the savoir-faire of the past. This sensibility is reflected in the current winemaking practices, too, and in the second-growth Margaux estate’s reputation (and critics’ scores) increasing year on year. The thing to emphasise is that what began with a biodynamic approach in the vineyards led to a series of domino effects that changed the character of the wines. In search of what Lurton calls greater ‘singularity’, the proportion of Cabernet Sauvignon had already risen to over 90% by 2014 (from around 75%); and with the use of indigenous yeasts during fermentation and the reduction of sulphur levels over time (initially sparked by Demeter’s upper limits of 70mg/l), the wines have become more aromatically complex and expressive. The introduction of amphorae by Italian producer Tava has allowed for microoxidation without overextraction, contributing to a more delicate balance of flavours, with the 2019 estate wine a blend aged one third in amphorae and the rest in barrel. ‘It’s not a big wine,’ says Lurton. ‘And it’s what I was looking for with biodynamics, in terms of style.’ Château des Graviers Christophe Landry’s pioneering status in Margaux stems from an instinct refined over decades at his own estate. He grows medicinal plants — horsetail, absinthe, calendula, chamomile — for vineyard treatments, as well as using the manure from his own cows. ‘What we need to remember is that biodynamics isn’t just a practice,’ he tells me. ‘It’s about finding your own path to self-sufficiency.’ His precision extends to the cellar, where he uses concrete tanks, amphorae and oak barrels (produced according to the biodynamic calendar) tailored to each of the five cépages’ oxygenation needs, then ages the wines for different lengths of time. Timing is everything, with harvest choices also following the biodynamic calendar. Obsessive care for the vines’ life cycles goes hand in hand with the level of precision in the cellar. The outcome is two phenomenal wines that are, as Landry puts it, ‘thirstquenching’. Château des Graviers and Quintessence — which contains a higher proportion of Petit Verdot and is aged longer in barrel and amphorae — are aromatically expressive, velvety and strikingly lively, with the latter offering more depth and an enveloping finish. Expanding to 18ha, Landry has also turned his focus to Clos Dufourg, cultivating vines on previously wild land nearby and hand-building a striking new cellar with cement tanks painted with clay from the surrounding earth. Le Puy For technical director Harold Langlais, the Le Puy estate’s significance lies in how it challenges Bordeaux’s conventional identity. Outside of the region’s traditional focus on appellations and classifications, Le Puy sits on a plateau near St-Emilion. The estate’s land is unusual, with no topsoil but a deep limestone bedrock beneath red-brown clay, which forces the vines to develop deep roots to access the earth’s natural water and nutrients. This is further supported by horse-ploughing and biodynamic sprays made from horsetail, buckthorn and nettles, which grow on the property. ‘Our approach focuses on rooting the vine deep,’ Langlais explains, ‘encouraging it to search out hidden nutrients.’ A vigorous wind circulates around the vines, and Langlais explains the effects of the elements. ‘The beauty of Le Puy is that it’s an acid factory. The whole place creates acidity in the berries.’ The biodynamic philosophy extends to the winemaking, with two different processes applied to their 100% Merlot cuvées. Cuvée Emilien uses a ‘decantation method’, or ‘fermentation by infusion’, while Barthélemy is produced with zero sulphites and a process of lees-stirring called ‘dynamisation’, which is done on fruit days and involves a specific motion to create a vortex in the old barrels it ages in. ‘Barthélemy is much more intense,’ Langlais says. ‘All the matter taken by the plant is in there.’
