The winery is located on the Right Bank of the Bordeaux wine region, in the commune of Pomerol in the department Gironde.
As all wine produced in this appellation, Château Certan de May is unclassified but the estate is long estimated among the great growths of the region.
[2] Archives state the family by royal ordonnance became masters of the fief of Certan, or Sertan, making this the oldest vignoble of the district, an area that also encompassed present day Vieux Château Certan and Château Certan-Giraud.
The French Revolution led to the division of the domain, leaving the de May family with a small parcel of the original property, then called Petit-Certan.
[2][3] After the death of the last de May in 1925 the estate came to the Barreau-Badar family, the present day owners.
