Clos d'Un Jour is in Duravel, one of 45 tiny communes in an appellation covering approximately 10,000 acres. The domaine is situated on the Lot River's third terrace, generally regarded as the appellation's best terroir. Stéphane and Véronique Azémar purchased the derelict, seven-hectare property in 2000. The vineyards are currently planted to 90% Malbec and 10% Merlot, which the Azémars have committed to farming organically. They allow the vines to compete with natural grasses for nutrients, and Ouessant sheep are used in the vineyards to control balance. Grasses prevent soil erosion and improve biodiversity. Sheep cause no mechanized stress and provide natural fertilizer. All work not done by the grazing sheep in the vineyard is manual. The domaine’s yields are limited to an average of only 25hl per hectare. Stéphane makes three expressions of Cahors utilizing three different methods of élevage: cement cuve; barrique; and ceramic amphora. In 2011, France's premier wine publication, La Revue du Vin de France, called Stéphane Azémar the coqueluche (darling) of the appellation in their annual Classement of the Meilleurs Vins de France, and recently elevated the domaine to ONE-STAR status in the 2013 edition. 14% abv.
