Saint-Émilion is one of the principal red wine areas of Bordeaux along with the Médoc, Graves and Pomerol. The region is much smaller than the Médoc and adjoins Pomerol. As in Pomerol and the other appellations on the right bank of the Gironde, the primary grape varieties used are the Merlot and Cabernet Franc, with relatively small amounts of Cabernet Sauvignon also being used by some châteaux.
