Chateau Potensac is a Cru Bourgeois estate located in the northern part of the Médoc, between the villages of Blaignan and Ordonnac; sitting on top of the Potensac plateau which gives the property its name. The estate has been in the same family for generations and has always passed through the female line. Today it is managed by Jean Hubert Delon, who inherited it from his paternal grandmother, Georgette Liquard. Delon also owns Chateau Léoville Las Cases and Clos de Marquis, both in in Saint-Julien, and Château Nénin in Pomerol. At Potensac 60 hectares are under vine planted on gravel with patches of clay and limestone. It is the limestone deposits that makes the soil of Potensac unique, which in some places is similar to that found in Saint-Emilion. The vineyards are planted with 48% Merlot, 33% Cabernet Sauvignon, 18% Cabernet Franc and 1% Petit Verdot. The average age of the vines is around 50 years, but they have some older vines of more than 80 years. The wines are aged for between 16 and 18 months in oak barrels passed down from Clos de Marquis, their estate in Saint-Julien. The Potensac style is pure Médoc - these are structured and firm, powerful wines with superb ageing potential. Their second wine is called La Chapelle de Potensac.
