Margaux is a wine growing commune and Appellation d'origine contrôlée within Haut-Médoc in Bordeaux, centred around the village of Margaux. Its leading (premier cru) château is also called Margaux. It contains 21 cru classé châteaux, more than any other commune in Bordeaux
Cabernet Sauvignon is the predominant grape, but it is invariably blended with other grapes. As with all red Bordeaux, Merlot, Cabernet Franc, Petit Verdot and Malbec may also be included in the blend (although wines will not necessarily include all five grapes). The wine is known for its perfumed fragrance. The dominant fruit flavour is blackcurrant. The wine from the southern part of the appellation (i.e. Cantenac, Arsac and Labarde) tends to be more powerful but less fragrant, and leans more towards plum.
Wine from Margaux may be labelled as Haut-Médoc (usually wine which the château considers inferior to its main offering and wishes to market under a different label). It would also be possible (though unusual) for the wine to be labelled using the Médoc AOC or one of the Regional Bordeaux AOCs.
