Described by Robert Haas as "one of the most unique and unusual domaines in France", Domaine du Mas Blanc consists of 18 acres. Famous for their full-bodied, rich, red Collioures and their intense, port-like Banyuls, the Parcé family has been in the region since 1625, and Dr. André Parcé was arguably the most famous of the family. A research chemist, he was mayor of Banyuls, chancellor of l'Académie International du Vin, and he successfully fought for Appellation Contrôlée status for Collioure in 1971. Responsible for vinification since the 1977 vintage, Jean-Michel Parcé has assumed complete responsibility since the death of his father in 1997.

Located in the south of France, bordering the Mediterranean Sea, lie Banyuls and Collioure. Just north of the Spanish border, terraces of schist rise high above the sea, reaching up to 1100 feet. The region is baked by the summer sun, but tempered by the mistral and tramontane winds. While there is very little rainfall during the growing season, in winter, often violent rains erode the steep terraces, necessitating replacement of the soil.
