Chateau La Mission Haut Brion Blanc is located in the Pessac-Léognan appellation of Bordeaux, France. The vineyard shares the same gravelly terrain as Haut-Brion (which sits just over the road), with small quartz stones over a clay-sand subsoil. Around 27 hectares (66 acres) are planted to red grapes, comprising 47 percent Cabernet Sauvignon, 43 percent Merlot and 10 percent Cabernet Franc. A little more than three hectares (seven acres) are planted to Semillon and Sauvignon Blanc. The estate takes its name from the Lazarite missionaries who owned it from 1682 until the French Revolution. It has been owned since 1983 by Domaine Clarence Dillon, the owner of Haut-Brion
