Fourth generation from a family of vine-growers, Bernard Defaix started with 2 ha in 1959. From this period, a method to protect the vineyard against spring frost was discovered. Thanks to this, the vine-growers could be sure to have a minimum of harvest every year and so they began to develop stable trade markets. The domain stretches over 27 hectares : Chablis Premier Cru (Côte de Lechet, Vaillons and Lys), Chablis and Petit Chablis. The 2009 year has brought a great change to us : we have officialized our vineyard's conversion into organic farming as we went through the official certification under the control of Ecocert. For many years yet, we have moved towards a sustainable and more ecological farming. Organic farming is the logical result of all this work.
