Château Mazeyres is a 25.5-hectare Bordeaux winery in the Pomerol appellation planted with 73% Merlot, 24% Cabernet Franc and about 3% Petit Verdot.

The estate is located on a Gallo-Roman site dating back to the 2nd century A.D., on the west and south terraces of the appellation, a ridge of sandy gravel with a subsoil of clayey gravel, part of which extends over the Catusseau plateau, made up of sand on a molasse subsoil very rich in iron dross.

The vines have been cultivated biodynamically since 2012 and the estate has been certified organic since 2015 and biodynamic since 2018.

Château Mazeyres is owned by Alain Moueix, who has also been at the helm of Château Fonroque in Saint-Emilion, another biodynamic estate since 2002.
