Château Sociando-Mallet is an outperforming Cru Bourgeois property located in the commune of Saint-Seurin-de-Cadourne in the Haut-Medoc. Quality was inconsistent until the property was purchased by Jean Gautreau in 1969. It then consisted of only 7 hectares and in the last 30 years, Jean Gautreau has expanded the vineyards to 57 hectares.
The vineyards, which lie close to the Gironde Estuary, are planted with Cabernet Sauvignon (60%), Merlot (25%), Cabernet Franc (25%) and Petit Verdot (5%). The grapes are handpicked and then fermented in a combination of stainless steel and concrete tanks. The wines are matured in oak barrels (70-90% new) for 12-15 months.
