Château Grand-Puy-Lacoste is a 125-acre estate in the Pauillac appellation. It is a Fifth Growth estate according to the 1855 Bordeaux classification. Several centuries ago this estate and Château Grand-Puy Ducasse were one estate, but in the 18th century part of the original estate was sold to Pierre Ducasse, and the remaining vineyards changed names as daughters of owners married. Today Grand-Puy-Lacoste is owned by the Jean-Eugene Borie family. The family has modernized the estate and its wines are now considered among the leading wines of Pauillac. The blend is usually 70% Cabernet Sauvignon, 25% Merlot and 5% Cabernet Franc. About 15,000 cases are produced a year.
