Château Pontet-Canet: Tasting 10 years of biodynamics

A pastoral outdoor lunch at the Château Pontet-Canet belied determination as Alfred Tesseron urged guests to taste all white wines before seating for the reds. Twelve certified organic and biodynamic wines from beyond the estate, including Nicolas Joly Clos de la Coulée de Serrant 2018 and Block 3 Pinot Noir Felton Road Central Otago 2013, proved a clever way to stress the family’s green passion as universal, extending further than Bordeaux.

As the Bordeaux 2021 vintage faced mildew, technical director Mathieu Bessonnet described how the tree bark Bourdaine fights fungal diseases and reduces treatments of Bouillie Bordelaise , the so-called 'Bordeaux mixture' of copper sulphate and quicklime sprayed as a fungicide. Bouillie Bordelaise is authorised organic, but the estate stresses its biodynamic infusions, beyond basic certification requirements, for naturally boosting vine defences. These include including yarrow, dandelion, wicker, rosemary and chamomile, which, for example, improves flowering and can fight the dangerous powdery mildew oidium. Pontet-Canet director Justine Tesseron showed how estate well water 'dynamises' such ingredients in tanks before workers spray infusions in the vineyard. She and brother Noé Tesseron posed with cow horns, which will be packed later this autumn with cow manure – the biodynamic (BD) 500 preparation – and buried underground for about six months before being 'dynamised' with water and sprayed to naturally help root development in the spring of 2022. And, unlike tractors, 12 estate horses currently on-site do not aggressively compact the soil, helping to avoid vine root development becoming constrained, Noé Tesseron said. After winter pruning, horses pull tools with biodynamic treatments to treat the cut wood. No time is set to replace all tractors with horses, but that is the goal. Biodynamic debate: A snapshot Some describe biodynamic winemaking as involving a lot of mysticism and marketing. Founder Rudolf Steiner, Austrian scientist and philosopher, described life forces that link the universe to living things, as related to cosmic and lunar rhythms. But Paz Levinson, Groupe Pic head sommelier present at the Pontet-Canet event, explained the practical side. 'Organic and biodynamic means producers care more for the vineyard, which wasn’t the case before,' she said. 'Fruit is better when the plant is more comfortable.' Levinson took part in a recent blind tasting of wines and found 'greater fruit purity and palate tension' from those certified organic and biodynamic. Some green-minded estates craft excellent wines without seeking certification commitments, which they consider too constraining in challenging vintages. 'The mildew this year (2021) will cut about 30% of our potential harvest,' said Nicolas de Bailliencourt, of Château Gazin in Pomerol, which has no certification. 'I cannot imagine not having that flexibility.' Pontet Canet lost two-thirds of its potential 2018 crop because of especially virulent mildew attacks, but Noé Tesseron counts that as a costly lesson learned. 'We did not react quickly enough,' he said. 'This year is different because the organic and biodynamic methods work, as long as we are on constant guard.' How this tasting worked The Tesseron family organised a vertical of all bottled wines since the dual certification (see tasting notes below) to showcase changes over time. Its 2012 vintage marked an essential change as the first that saw 35% of the wine aged in concrete amphorae, whose walls also included estate soils like gravel and limestone. A brochure says the strategy was 'extending terroir into cellars'. Bordeaux oenologist and barrel expert Nicolas Vivas says that the reduction of new oak (accounting now for 50%) plus the use of amphorae for ageing have 'improved fruit purity, noticeably' at Pontet-Canet. The evening before, the Tesserons poured older vintages – including a 1945 in magnum and an amazing 1961, from a 75cl bottle – to reflect inherent excellence of the 81-hectare estate, planted to more than 60% Cabernet Sauvignon. A key ingredient in this success is its well-drained outcrop of Günz gravel over limestone. The cosy dinner ambiance reinforced family ownership, rare today among Médoc châteaux. Since its founding in the 18th century, only three families have owned the estate: the original Pontet owners, who witnessed the birth of the 1855 Classification, followed by the Cruses from 1865 and the Tesserons from 1975. And unlike many other classified estates, Château Pontet-Canet has not changed very much, stresses technical director Bessonnet, who found an 1818 map of the vineyard that is similar to today. Almost immediately after taking over from his father in 1994, Alfred Tesseron embarked on a green voyage, with substantial assistance over 30 years with technical director Jean-Michel Comme . [breakout] Pontet-Canet's going 'green' timeline 2004 – Following test on 14 hectares, decision made to convert entire vineyard to biodynamic 2007 – Biodynamic conversion set back when chemical spraying used to protect crop from rot 2008 – Draft horses first used to avoid soil compaction 2010 – Pontet Canet wines certified organic by Ecocert and biodynamic by Biodyvin 2012 – Concrete amphorae made from estate soils introduced for ageing wine 2014 – Pontet Canet wines certified biodynamic by Demeter 2015 – First year that no second wine is produced 2018 – Despite devastating mildew attack, the estate stays green 2020 – Mathieu Bessonnet replaces technical director Jean-Michel Comme, whose 30 years at the estate contributed enormously to the biodynamic vision [/breakout] How the wines showed themselves The vertical on-show here proved that vintages since the dual certification can display more focus, fruit purity and tension. Pontet-Canet 2010, for example, has more depth, clarity and nuance than the excellent but more traditionally styled 2000. The 2016, meanwhile, surpasses the 2010. And extra vineyard (and winemaking) care contributed to a fine performance for the very difficult 2013 vintage. Vintage quality still matters, whether certified or not. The 2017, for example, engaged most tasters less than the superlative 2010, the fantastic 2016 or the flamboyant 2018. Jeff Zacharia, president of US-based Zachys Fine Wine, acknowledges organic and biodynamic as important factors for Pontet-Canet having become 'more interesting since 2010', but he added that 'buyers need to keep a closer eye on vintage variation in terms of both quantity and quality'. The magical 1961 vintage tasted over dinner at the château reflects the superb Cabernet-driven terroir. 'Chemical treatments did not really come into the picture in Bordeaux until the mid-1960s,' remarked Bessonnet. Although the estate used more Bouillie Bordelaise back then, farm animals were used in the immediate post-war years, he added. In some ways, the movement towards organic and biodynamic winemaking is a return to a simpler era of less intervention, but more enlightened, with greater knowledge of viticulture and vinification. Many of the latter vintages illustrate this.

Organic wine is made from certified organic grapes. The use of pesticides or synthetic fertilisers is not allowed in organic winemaking. European standards allow for added sulphites during winemaking, but with limits. Biodynamic certification requires biodiversity and ecosystem preservation, soil husbandry, livestock integration, prohibition of genetically engineered organisms and viewing the vineyard as a living 'holistic organism'. Demeter certification, for example, requires specific preventive plant protection measures, a good knowledge of microclimate and reducing interference during vinification. Biodynamic wines employ organic practices, as they avoid pesticides and depend on compost, rather than chemical fertiliser. The majority of these wines are thus also organic in practice.
