Clos St. Martin is owned and managed by Sophie Fourcade, a descendant of the Reiffers family, established wine producers in Saint-Emilion since the 17th century, with Michel Rolland acting as consultant winemaker.

The wines are exclusively distributed by Établissements Jean-Pierre Moueix, now directed by Christian Moueix, who runs the family business alongside his children, Edouard and Charlotte.
