Château Duplessis used to be part of the estate owned in Guyenne by the family of Armand du Plessis, Cardinal de Richelieu. Popular for hunting parties in the 18th century, it burnt down, and all that remains today are the thick walls that provided a basis for more recent construction.

Duplessis' wines are characterized by their beautiful colour and rich substance; a solid tannic structure gives them a good capacity to age.
