 Further divisions in the 1860s resulted in what would become Chasse-Spleen, and the châteaux Maucaillou and Poujeaux.One account explaining the estate's name comes from a visit by Lord Byron in 1821, when he became so enthralled by the vines that he said, ""Quel remede pour chasser le spleen"", or alternately attributed to the poem "Spleen" whose author Charles Baudelaire once visited the property.After the death of the last Castaing, from 1909 to 1914 Chasse-Spleen was owned by the Segnitz family, north-German wine merchants who contributed to the quality and reputation of the estate, but after the outbreak of World War I the estate was confiscated as "enemy property", and eventually bought by auction in 1922 by the Lahary family.
