Château d'Issan is a castle and winery in the Margaux appellation of the Bordeaux region of France. The Château d'Issan is made of 120 hectares, of which 50 are dedicated to the culture of the vines. The grapes used to produce the great wine of the château (ranked third in 1855's classification) and the second wine, Blason d'Issan, are the cabernet sauvignon and the merlot. The use of these varieties allows the château d'Issan to propose typical wine of Margaux with the strength of a Pauillac.
