Château La Mission Haut-Brion is the chief challenger to neighbour Château Haut-Brion for supremacy in the Pessac-Léognan appellation. In 1983 the estate was acquired by Domaine Clarence Dillion – the owners of Haut-Brion since 1935. Situated on uniquely stony soil, the vineyard area extends nearly 21 hectares (52 acres) between the two portions in Pessac and Léognan, with a grape variety distribution of 48% Cabernet Sauvignon, 45% Merlot, and 7% Cabernet Franc. Cultivated by monks until the French Revolution, the Chateau produces approximately 6,000-7,000 cases per annum. There is also a second wine called La Chapelle de la Mission, from the vineyard's younger vines (4,000 cases annually). La Mission Haut-Brion is a strong contender for First Growth status. The red is consistently powerful with dark plum and earthy notes, requiring at least 10 years cellaring. There is also one of Bordeaux’s top whites simply called La Mission Haut-Brion Blanc.
