Chateau de Pez estate lies in the western part of Saint-Estephe, and has held the auspicious 'Cru Bourgeois' classification since 1932. The wine is made of Merlot and Cabernet Sauvignon in roughly equal measures, which gives the wine a rich, deep character. The Domain of Pez was originally established in the 15th Century, but the vineyards were added later by the Pontac family (then-owners of Chateau Haut-Brion) who took over the control of the estate in 1585. It is one of Bordeaux's oldest estates, and was passed down through generations of the Pontac family until the French Revolution, when it became the property of the French state. Throughout the 20th century it was owned by a succession of people, and came under ownership of Louis Roederer in 1995.
