Château les Carmes Haut-Brion is a Bordeaux wine estate located in the AOC Pessac-Léognan within the region of Graves. In addition to producing a red grand vin named Château les Carmes Haut-Brion, the estate produces the red second wine Le C des Carmes. Château les Carmes Haut-Brion is the only Bordeaux chateau to be actually in Bordeaux, at the unique address of 20, Rue des Carmes. Although the vineyard was historically ‘outside the walls’, it is now entirely within the city, a walled vineyard in urban surroundings. The exceptional location of the estate, ten hectares in size including six hectares of vineyards, means that it enjoys a privileged environment with a milder microclimate and a well-preserved ecosystem that work together to ensure perfectly ripe grapes. The terroir, a mixture of Mindel gravel, sand, and clay over a limestone subsoil, forms a unique geological spectrum that has informed this vineyard's unusual mix of grape varieties, consisting of 40% Cabernet Franc, 18% Cabernet Sauvignon and the remainder Merlot. The vines are an average of 42 years old and are planted with a density of 10,000 per hectare.

Pessac-Léognan is a wine growing area and Appellation d'Origine Contrôlée, in the northern part of the Graves region of Bordeaux. 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.
