The name "Between two seas" of the 23,000 hectare area in the south-east of the Bordeaux region is derived from its location between the two rivers (not seas, actually) Garonne and Dordogne. The Entre-deux-Mers appellation itself is only about 2,400 hectares in size. Only dry white wines are permitted, for which the predominantly clay and gravel soil is ideal. They are made from the varieties Sauvignon Blanc, Sémillon, Muscadelle (zum. 70%), Merlot Blanc (max. 30%), as well as Colombard, Mauzac Blanc and Ugni Blanc = Trebbiano Toscano (max. 10%). The southern municipalities of Arbis, Cantois, Escoussans, Cornac, Ladaux, Mourens, Saint-Pierre-de-Bat, Soulignac and Targon have the right to use the appellation Entre-deux-Mers Haut-Benauge. Wines with more than 4 g/l residual sugar can be marketed as Bordeaux Haut-Benauge. However, both designations are rarely used. The red wines are mainly blended from the Merlot and Cabernet Sauvignon varieties and account for 75% of production. They are marketed as Bordeaux or Bordeaux Supérieur.
