Château Chasse-Spleen is a prominent Bordeaux wine estate in Moulis-en-Médoc spanning 135 hectares, recognized as the leading Cru Bourgeois of the Moulis appellation. Though not classified as a grand cru, the château regularly outperforms many of the Médoc's renowned classified growths. Documented viticultural history extends back to 1560, with the modern era beginning in 1976 when the Merlaut family purchased the estate and expanded it into one of the Médoc's largest vineyards. The vineyard is planted to 52% Cabernet Sauvignon, 39% Merlot, 5% Petit Verdot, and 4% Cabernet Franc. Legend suggests the château's distinctive name traces to Lord Byron's 1821 visit, when he remarked on its wine as a remedy for melancholy—quel remède pour chasser le spleen.
