The appellation spreads over Margaux-Cantenac, Soussans, Labarde and Arsac, and is worked by 62 estates. Its 21 classified growths of 1855 are the highest count in the Médoc, out of 61 growths in the whole classification. The soils are gravel carried by the Garonne, laid down in six kinds of terrace during the Quaternary, with sandy clay over limestone or clay-marl beneath: thin, poor ground that the Bordeaux wine council credits for tannins that last.

Margaux is red only, blended mainly from Cabernet Sauvignon and Merlot with Petit Verdot, Cabernet Franc and, in smaller amounts, Malbec and Carménère. The Bordeaux wine council describes the wines by their delicacy, smooth tannins and fruit, and by their finesse, harmony and elegance; where Pauillac is known for power, Margaux is known for finesse. The wines age gracefully on the strength of that thin soil.

One estate with its own page here is Château Margaux, the first growth of the appellation, whose second wine is Pavillon Rouge. The other classified growths and crus bourgeois of Margaux share the same four communes and the same gravel.

The wines above are every Margaux in the cellar. See also Pauillac, Saint-Julien, Saint-Estèphe or the full range of Bordeaux wines.
