The largest estate in the Moulis appellation, the vineyards of Château Chasse-Spleen span 100ha, planted to predominantly Cabernet Sauvignon, with smaller percentages of Merlot, Petit Verdot and Cabernet Franc vines. The estate was given the name of `Chasse-Spleen` or `chase away melancholy` in 1862 after a Baudelaire poem.

The 2009 vintage is described by Derek Smedley MW as follows, "There are a lot of concentrated flavours with rich cassis backed by firmer fresher sloe and bilberry. The rounded tannins add suppleness and the ripeness of the fruit gives flesh on the mid palate and richness at the back. Drink 2020-2040."
