Saint-Estèphe is one of the many famous Left Bank red wine appellations of Bordeaux, known for reds based on Cabernet Sauvignon and Merlot. Situated at the northern end of the Haut-Médoc region on the gravelly western shores of the Gironde estuary, Saint-Estèphe is separated from its famous neighbor, Pauillac, only by a stream, yet there are significant differences between them. With 1,229 hectares (3036 acres) it accounts for 8 percent of the vineyard area of the Médoc.
