Appellation Bordeaux Contrôlée (AOC Bordeaux) is a designation given to wines that are produced in a specific area in southwestern France that includes the city of Bordeaux. The AOC Bordeaux designation is one of the largest wine appellations in the Bordeaux region and has specific requirements for grape varieties, winemaking techniques, and aging. To be labeled AOC Bordeaux, wines must be made from grapes grown within the designated area and must meet strict standards of quality and authenticity. The AOC Bordeaux designation applies to both red and white wines, and to sweet wines such as Sauternes.
