St.-Estèphe is the northernmost of the 4 communes hugging the Dordogne river in the Northern Haut-Médoc. While the appellation has no premier crus (first growths) of its own, it's southernmost chateau, Cos d'Estournel, is a second growth, and separated from famed Lafite-Rothschild in Pauillac by only a stream. Some years Cos d'Estournel produces wine of a first growth level.
