The modern era for Chateau Chasse Spleen starts in 1976 when the estate was bought by the Merlaut family. At the time of the purchase, Chasse Spleen owned about 40 hectares of vines. Under the direction of Jacques Merlaut and his daughter, Bernadotte Villars they expanded their vineyard holdings so that today, Chasse Spleen has 80 hectares of vines. They replanted large sections of the vineyard to increase the vine density. They also updated and modernized their wine making facilities.
