Château Potensac is one of the three estates owned by the Delon family, with the other two being Château Léoville Las Cases in Saint Julien and Château Nenin in Pomerol.
This estate has always been handed down by women in the family. Château Potensac is currently owned by Jean-Hubert Delon, who inherited the estate from his grandmother.
Château Potensac is located on a high point in North Médoc. The vineyard is over 84 hectares, on mainly hilly mounds with a limestone subsoil covered with clay and gravel. Some of the Cabernet Sauvignon and Cabernet Franc vines on the estate are over 80 years old.
