Stephane Aviron has been producing wines from this incredible 13.6-acre parcel since 1993. The soil is light and made up mostly of sand and small pebbles over a layer of clay and quartz. The old vines and poor soils combine for incredibly low yields and highly concentrated grapes. Vinification: The Chenas is vinified using traditional methods using whole bunches.. The must is macerated for seven days in temperature controlled stainless steel vats. The wine is aged for 12 months in cement tank to maintain to purity of the fruit.
