Unlike most Bordeaux appellations, Pessac-Léognan is recognised for both red and (dry) white wine, although red wine is still predominant. It includes the only red-wine producer outside the Haut-Médoc classified in the Bordeaux Wine Official Classification of 1855, the premier cru Château Haut-Brion, and also all of the châteaux listed in the 1953/59 classification of Graves. These classed growths account for a third of the wine produced in Pessac-Léognan.
