In 1969, in search of a wine estate for sale for one of his Belgian customers, he discovered Sociando-Mallet in the commune of Saint-Seurin-de-Cadourne. It has a real love at first sight for this property, however in a sorry state, but offers a magnificent panorama on the estuary of the Gironde. He therefore immediately decides to buy it for himself, and against the sum of 250,000 French Francs.

The Demoiselle de Sociando-Mallet is produced from the younger vines of the property and the plots whose soil is more favorable to the production of very good Merlot. Blending: 64% Merlot, 36% Cabernet Sauvignon, 

The 2018 vintage is a jewel in Bordeaux. Light rainfall combined with exceptional weather at the end of the season resulted in the perfect ripening of the grapes and very good quality throughout the Médoc.
