The term "grand vin" translates to "great wine" in English and refers to the top wine produced by the chateau. The grapes used in the production of grand vin de Bordeaux are usually from the best plots of land on a chateau’s estate and are carefully selected and harvested by hand to ensure the highest quality. These wines are typically aged in oak barrels for several years before being bottled and released for sale. Grand vin de Bordeaux is known for its complexity, depth, and aging potential. Some of the most famous chateaux producing grand vin de Bordeaux include Chateau Margaux, Chateau Lafite Rothschild, Chateau Latour, and Chateau Mouton Rothschild.
