The 30 hectares vineyard all in one piece is planted on the clay-limestone part of the town of Saint Seurin de Cadourne. It consists of nice hillcrests and south facing slight slopes with 75% Merlot and 25% Cabernet Sauvignon.
The vines are 20 years old on an average and are planted on a limestone soil which brings all the freshness and fineness typical of the great wines of Bordeaux. Thus the replanting program since the acquisition of the property in 1998, has led, due to the nature of the soil, to a grape variety with a very strong Merlot dominant. The new Cabernet Franc plantations will give Château Doyac wine a structuring effect.
