Château Certan de May, fully named Château Certan de May de Certan, 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. It is located in the east of the appellation, on the Pomerol plateau between Vieux- Château-Certan and Pétrus, and directly opposite Le Pin.
Pomerol is located on the Right Bank of the Dordogne river in Bordeaux, just north of the city of Liborne. The region shares maritime influences with other parts of Bordeaux, but its general distance from the coast makes it more continental than the Médoc. The area is planted primarily to Merlot and, to a lesser extent, Cabernet Franc. The diverse soils found in the region range from gravel to sand to clay, including the unique blue-clay known as ‘molasse’.
