During the summer 2011, Château Quintus was purchased by Domaine Clarence Dillon. Domaine Clarence Dillon named its new property after the Gallo-Roman tradition of naming their fifth child Quintus. For almost a century, the Bordeaux reference book Cocks and Feret mentioned the property as a First Growth of Saint-Emilion. The property also received a gold medal at the Exposition Universelle de Paris in 1867.
