The Haut-Médoc appellation stretches over some 50km from north to south.  Interestingly there are only five properties that are part of the 1855 Classification that lie outside the classic communes of Saint-Estèphe, Pauillac, Saint-Julien, Margaux and Pessac-Léognan.  These châteaux are La Tour-Carnet, Belgrave Camensac, Cantemerle and La Lagune.

The soils are mixed and diverse leading to a number of different styles and quality levels.  Some say the quality of some of the less known wines are rising faster than their more famous namesakes.
