The Chanfreau Family settled in Listrac-Médoc in 1962 when Léo purchased Château Fonréaud following his return from Algeria. A few months later, his father, Marcel Chanfreau, who also wished to settle in the Médoc, bought Château Lestage (neighbouring Fonréaud) and Château Caroline.
Today, Marcel's grandson, Jean Chanfreau, runs the estates with his wife Marie-Hélène and his sister Caroline Chanfreau-Philippon. He bought Clos des Demoiselles in 2002. The family-owned vineyard covers 42 hectares in the commune of Listrac-Médoc and 9 hectares in the commune of Moulis en Médoc. The vines grow at the highest point in the Médoc, the Puy de Menjon, at an altitude of 43 metres.
