Owned by Sogecap (a life insurance branch of the Société Générale group) from 2010 to 2020, Château Mazeyres, which has been run by Alain Moueix since 1992, was bought by the Guillard family in 2020. The estate has grown recently to reach a little over 25 hectares in size. It is also being run under biodynamic principles now. The vineyard is spread over two terroirs, one of which lies on a ridge of sandy gravel with a clayey-gravel sub-soil, while the other is constituted of sand with a molasse sub-soil rich in the famous iron dross typical of legendary Pomerols. The estate produces 120,000 bottle (of which 50,000 are the second wine called Le Seuil de Mazeyres)

The wines are a beautiful garnet colour on tasting with a nice range of aromas (violets, lilac, dark berries), and are rounded and creamy with good length on the palate which can be enjoyed while young.
