Bordeaux is probably the most well-know wine region in France. Bordeaux counts for one third of the good quality french wine (AOC, crus bourgeois, crus classés). The wines are so good there that a Bordeaux ranking is needed to classify the best of the best. Some of them are universal: Margaux, Yquem, Pétrus, Cheval Blanc, Haut Brion and all the others. Bordeaux has about 7,000 chateaux !
