Entre-Deux-Mers, as the name suggests, refers to the wine-growing regions located between the Garonne and Dordogne rivers in Bordeaux. Geographically, this is the largest sub-region of Bordeaux, but much of the area is forested and only 3,700 acres is under vine, that being split between 250-odd producers.

Only white wines are entitled to use the Entre-Deux-Mers name on the label with reds being sold as straight Bordeaux Rouge or Bordeaux Superieur. The blend is typically dominated by Sauvignon Blanc. (Wine/Appellations)
