Château Nenin is a large property by Pomerol standards and one which has long been a favorite of the British Royal Family. Nenin was owned by the Despujol family until 1997 when it was bought by Jean-Hubert and Michel Delon, the proprietors of Château Léoville-Las-Cases. Eric Boissenet has been retained as a consultant and the wines are now cleaner and displaying more depth of fruit than before.

Nenin is located just outside the village of Catusseau and consists of a handsome, 19th century château and a vineyard set in a large park. The vineyard is south-west facing and located on a high plateau, where the soils are a mixture of deep gravels and sand. 9 hectares on this very plateau are strictly dedicated to the Grand Vin, while the balance of 18 hectares are the vines producing the second wine, the Fugue de Nénin.

Nenin is a blend of 70% Merlot, and 30% Cabernet Franc. The grapes are hand harvested in one-layer baskets and then fermented in temperature-controlled, stainless-steel vats. The wine is then matured in oak casks (30% new) for 14 to 18 months.
