Sociando-Mallet's terroir consists of Günz gravel over a deep layer of clay-limestone soil. This terroir perfectly regulates water supply and enables Cabernet Sauvignon to ripen extremely well and Merlot to acquire depth and complexity. This terroir is Sociando's soul. It provides the wine with complex structure, freshness, and elegance.
Primarily located east of the village of Saint-Seurin, the property stretches over a total of 120 hectares, of which 83 are under vine. The vines grow on the superb Baleyron gravelly hillock around the house and winery buildings. Sun exposure is optimum and breezes off the estuary keep the vines well aired and healthy. The huge mass of water in the estuary and nearby ocean accounts for a temperate microclimate without wild swings in temperature.
Grape varieties consist of 42% Cabernet Sauvignon, 54% Merlot, and 4% Cabernet Franc. The vines are an average 35 years old.
