Anson: A Château Cos d’Estournel tasting masterclass

Decanter’s second virtual masterclass, held with Château Cos d’Estournel, was as international as the first, with attendees joining from Belgium, Czech Republic, Estonia, France, Hong Kong, Hungary, Ireland, Netherlands, Norway, Portugal, Romania, Sweden, Switzerland, United Arab Emirates, United Kingdom and the USA. The tasting was led by the second growth estate’s technical director, Dominique Arangoïts, and held from the château itself in St-Estèphe.

I spoke with Michel Reybier a few years ago about how it felt to arrive at one of Bordeaux’s most prestigious estates as an outsider, even one with vast experience in the luxury hospitality business. ‘It’s tough to enter a new industry’, he told me. ‘The bureaucracy of any French business is difficult. In many ways, Bordeaux has its own language, and perhaps the Bordelais don’t always see how lucky they are to be here. Coming from the outside, that was clear to me.’ He added, ‘To succeed, you need a bit of humility and a bit of luck, but you also need to remember that some things don’t change – namely, you need a team that believes in the same things that you do and is prepared to work hard.’ [breakout] Château Cos d’Estournel Factfile 1855 classification : Second growth Wines produced : Cos d’Estournel, Pagodes de Cos, Cos d’Estournel Blanc. Total area under vine : 100 hectares (ha) - 87ha in 2018. Grape mix in the vineyard : 56% Cabernet Sauvignon , 40% Merlot , 4% Cabernet Franc , 1% Petit Verdot. Owner : Michel Reybier since 2000. Director : Dominique Arangoïts. Cellar master : Angélique Meynieu. History : Named after Louis Gaspard d’Estournel, who inherited a few plots of vines from his father in 1791 and built it up into one of the region’s most prestigious and distinctive estates. Construction of the Château in 1820 (complete with sandstone turrets and pagodas) was inspired by his many trips to India and a love of the Taj Mahal. A bronze of Louis-Gaspard sits in the estate’s gardens. Winery : Designed by architect Jean-Michel Wilmotte, the winery is one of the most modern in Bordeaux , covering 2,000 square metres of floorspace with split levels and a full gravity-flow system, with 84 stainless steel tanks of various sizes to allow plot-specific winemaking. Took five years to build, with the first harvest in 2008. Other Reybier-owned estates : Hetszolo (Tokaj), La Mascaronne (Provence), Champagne Michel Reybier.[/breakout] Tasting the Cos d'Estournel wines This tasting was organised to show the progression of the estate over the past two decades, including the impact of greater precision in the vineyard and in the approach to winemaking, together with investments in a technologically-advanced, gravity-led cellar. Watch the video of the Cos d'Estournel virtual tasting The tasting opened with the 2017 vintage of Cos d’Estournel Blanc, a white wine label that was introduced in 2005 and is produced only in tiny quantities; between 500 and 800 cases are made annually depending on vintage. This was followed by the 2016 and the 2010 vintages of both Cos d’Estournel and Pagodes de Cos, allowing us to compare the difference in fruit structure and composition between not only these two vintages but also first and second wine. It finished with the Cos d’Estournel 1996, an exceptional year for the estate and a wine that is perfectly in its drinking window – and that shows the great terroirs of the 1855 Classification have a magic that transcends individual owners. The Cos d'Estournel vineyards ‘The choice of plots for Pagodes and Cos are not set each year,’ said Arangoïts. ‘For example, as vines age and deepen in complexity, they may be moved from Pagodes into Cos, or in certain vintage conditions different parts of the vineyard may be used for one or the other. 'There is also less new oak in the Pagodes, because the vines are often younger and produce less tannic, concentrated wine. They therefore don’t need to same amount of oxygen exchange that barrels provide during ageing to soften the tannins.’ He added, ‘There are 19 different soils types across the 100ha of Cos d’Estournel’s vineyard, which explains the incredible complexity in the wines’. To the south lies the Jalle du Breuil stream, which separates St-Estèphe from Pauillac, and Cos from neighbouring estate Lafite Rothschild. ‘The water from this Jalle is also extremely important for regulating temperature and allowing the vines to access nourishment in hot summers, such as we have had recently,’ said Arangoïts. A 'hands-on' approach He also discussed the importance to the estate’s overall philosophy that comes from Michel Reybier owning a number of luxury hotel and restaurants, including La Réserve in Paris, Zurich and Geneva, the Intercontinental in Davos and La Maison d’Estournel in St-Estèphe. This last property was once the family home of Cos founder Louis Gaspard d’Estournel, and has recently been repurposed into a hotel and restaurant. ‘Being part of a hospitality group means we have direct contact on a regular basis with the people that are drinking our wines,’ said Arangoïts. ‘[This] gives us a connection to them, something that is not always true in the system of Bordeaux, where négociants sell the wines rather than the châteaux directly.’ It also helps that Michel Reybier and his son, Raphaël, are hands-on owners, spending much of the year at the property. ‘Many château owners don’t seem to go out into the vineyards enough to see the process of growing the grapes, to really check on the quality of their raw material,’ Reybier told me in our earlier conversation. ‘But today, simply having a high price is not enough, even for classified growths. Consumers want to know what stands behind the price, and an owner needs to be able to answer those questions.’ Friday night’s masterclass finished with a round of questions, when Arangoïts was asked for his favourite vintage of Cos. He chose the 1985, which he said remains a model of excellence in winemaking for him even today. ‘I prefer to drink wine I didn't make,’ he said. ‘You know, when I make wine I am working, I don't like that, I feel stressed.'
