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.’
