Château de Costis is a family-run Bordeaux estate in Entre-deux-Mers, owned by the four Mazeau brothers within the Vignobles Laurent Mazeau-Bergström group. Acquired by Charles Mallet in 1928 and passed through his descendants, the property is now led by Laurent Mazeau, who oversees operations and winemaking. The estate follows sustainable viticultural practices without cited formal certification. Its red wines focus on Merlot, Cabernet Franc and Cabernet Sauvignon, with vinification carried out in Laurent Mazeau’s cellar in Targon.
