Until the 19th century, the Léoville estate was one of the largest and oldest vintages in the Médoc. It stretched from the Chateau Beychevelle vineyard to the Chateau Latour en Pauillac. It has been divided into three parts:
Château Léoville Las Cases; Château Léoville Barton; and Château Léoville Poyferré.
Château Léoville Poyferré was born in 1840, when the daughter of the Marquis de Las Cases married Baron Jean-Marie de Poyferré de Cère, taking her share of the great Léoville vineyard. In 1920, the civil society of the estates of Saint-Julien, a property of the Cuvelier family, took over the estate.
Château Léoville Poyferré is now considered to be one of St Julien's finest estates thanks to significant work in the last 20 years by current owner Didier Cuvelier and wine consultant Michel Rolland.
