Château Léoville-Las Cases is an estate in the Saint-Julien appellation of Bordeaux, ranked as a second growth in the 1855 Classification of the Médoc and Graves. Typical of the appellation, Château Léoville-Las Cases is Cabernet Sauvignon-dominant, with smaller amounts of Merlot and Cabernet Franc. The estate has a history dating back to the mid-17th Century, when it used to be part of a much larger estate. During the French Revolution (1789-1799) the estate was divided in two with a small section becoming Château Léoville Barton. In 1840, the original estate was again divided, creating Château Léoville-Poyferre. All three of the Léoville châteaux were named in the 1855 Classification as second growths, but Léoville-Las Cases remains the largest.
There are 98 hectares (242 acres) of vineyards, planted with 66 percent Cabernet Sauvignon, 24 percent Merlot, 9 percent Cabernet Franc and 1 percent Petit Verdot. The vineyard’s soils are mostly gravel over sand and clay, with some areas where the clay reaches the surface. The proximity of the Gironde moderates weather extremes, lowering the risk of frost and allowing grapes to ripen earlier than vineyards further inland. The vines are on average 40 years old.
