Château La Mission Haut-Brion's vineyard straddles the commune of Talence and Pessac and is located only a few miles southwest of Bordeaux's city center. It belongs to the Pessac-Léognan appellation, to the north of the Graves wine-growing region. The property is situated just opposite that of Château Haut-Brion and shares the same gravelly and elevated terrain ideal for cultivating vines, bounded by the Le Peugue and Le Serpent streams, already referred to under the name Haut-Brion on ancient maps and deeds. The nature of the gravel at Château La Mission Haut-Brion, consisting of small stones of various types of quartz, is a key element contributing to the particularly valuable wine-growing potential of the soil. The sub-soil consists of a mixture of clay and sand. The vineyard covers an area of 29 hectares (about 72 acres). 25.5 hectares are planted with red grape varieties (Merlot, Cabernet Sauvignon and Cabernet Franc) and just over 3.5 hectares are devoted to Sémillon and Sauvignon Blanc.
