Chasse Spleen is a Cru Bourgeois in the Moulis appellation. It vies with the likes of Poujeaux for the number one spot in this southern Médoc commune that is home to a number of great value clarets. Often tannic in their youth, the wines do need 6 or 8 years in the bottle before reaching maturity, but thereafter they can age very well indeed. This estate was particularly successful in the magnificent 2009 and 2010 vintages and the trend is towards a more accessible, earlier drinking style.
With the exception of Haut Brion, all the Chateaux listed in the 1855 classification are situated in the Medoc, however, as with the Haut Medoc, most of the grand names defer to their more specific appellations. This is a vast AOC with around 1500 different wine-making estates. There are many good AOC Medoc wines, which did belong to the now defunct Cru Bourgois classification. The most notable estate is Potensac, which is owned by Leoville Las Cases.
