Located in the southwest of France, Bordeaux is the single largest fine-wine-producing region in the world, with more than 15,000 growers spread over 57 appellations and more than 700 million bottles produced annually. The region boasts a two-thousand-year winemaking history and some of the wine world's most recognized and highly sought-after names. Red Bordeaux blends comprise eighty percent of production, but dry and sweet whites are also well-known. The region is divided into the Left and Right Banks (of the Dordogne River); Cabernet Sauvignon prevails in the former and Merlot in the latter.
