Château la Mission Haut-Brion is on uniquely stony soil in the Pessac-Léognan appellation close to the city of Bordeaux. It is a Cru Classé in the Graves Classification of 1953. The 22.5 hectare red wine vineyard is planted to Cabernet Sauvignon (46%), Merlot (44%) and Cabernet Franc (10%). The chateau wine is vinified in large (180hl) temperature-controlled, stainless steel vats and aged in 100% new French oak for an average of 22 months. Annual production is 6000-7000 dozen. The famous white wine of the chateau comes from 3.5 ha planted to Semillon (62%) and Sauvignon Blanc (38%). Overall planting density is 10,000 vines per hectare (red) and 8000 vines per hectare (white). Since 1983, under the ownership of Domaine Clarence Dillon (which also owns the neighbouring Chateau Haut Brion), the entire estate has been renovated vineyards, winemaking facilities and the chateau itself. The property got its name in the 1600s when it was owned by the Catholic Church.

With one of the longest and most pedigreed histories in the Medoc region, Chateau Leoville-Las-Cases has passed through the hands of some of Frances most notable and wealthiest noble families. Today, the estate is family owned by the Delons, of which brother Jean Hubert and sister Genevieve manage proceedings. Their second wine, Le Petit Lion du Marquis de Las Cases, is a relative newcomer, only having been released for the first time in 2009.
