Margaux is the name of the wine appellation d'origine, Margaux AOC, that encompasses the village and the neighbouring villages of Arsac, Labarde, Soussans and Cantenac, and is the most southerly of Médoc's appellations.
The 1855 classification contained more wines from Margaux than from any other appellation, and its best-known vineyard, Château Margaux, was one of only four wines to be awarded the Premier Cru status.
