Château Chasse-Spleen is the leading Moulis estate along with Château Poujeaux. Although it is classified only as a Cru Bourgeois, it regularly outperforms many of the Médoc's more renowned classed growths. There are two theories behind the château's rather unusual name: firstly, that, when Lord Byron visited the estate in 1821, he remarked `Quel remède pour chasser le spleen`. Secondly, that it is named after Baudelaire's poem, Spleen.
