Travelling north from the ancient wine regions of Graves and Sauternes we come to the Médoc, and first of all to the wines known as Margaux. There are a number of villages here, some of which will be vicariously familiar - Cantenac, for example, as in Brane-Cantenac, Cantenac-Brown and Boyd-Cantenac - but it is Margaux that has come to dominate, giving its name not only to the appellation as a whole, but also the region’s only Premier Grand Cru Classé estate, Chateau Margaux.
