Entre-Deux-Mers is the appellation “between two seas,” as the name charmingly suggests. The “seas” are actually the two important Bordeaux rivers, the Dordogne and the Garonne. The appellation has nearly 7,500 acres, which makes it the largest appellation in Bordeaux. The Entre-Deux-Mers appellation only includes white wines made from Sauvignon Blanc, Semillon and Muscadelle. Though the fashion for these white wines once was to make them slightly sweet, today most are crisp and dry. Red wines sold in this region are labeled as Bordeaux AC or Bordeaux Supérior AC.
