This small, 30 acre estate of Château du Moulin de Peyronin has been in organic production since 1975, although the family that started the winery pioneered the sustainable agriculture movement as early as 1966 in their other vineyards in Languedoc, Domaine de Clairac.
The château is situated in the commune of Pujols in the eastern part of Gironde. This area produces only wines bearing a Bordeaux label. The grapes grown include Cabernet Sauvignon, Merlot, and Malbec for the red Bordeaux wines and Semillon for the white Bordeaux. They are certified by Ecocert.
