Chateaux Greysac is a perennial favourite. This 95 hectare estate can be found on the gravelly soils around the village of By, north of St Estephe. Plantings are dominated by Cabernet Sauvignon (50%) and Merlot (38%), with Cabernet Franc (10%) and Petit Verdot (2%). The average age of vines is 30 years. Wines are fermented in stainless steel tanks, before aging in oak barrels for 12 months. The style tends to be old fashioned, traditional claret; medium-bodied, subtle, elegant and with the ability to age.
With the exception of Haut Brion, all the Chateaux listed in the 1855 classification are situated in the Medoc, however, as with the Haut Medoc, most of the grand names defer to their more specific appellations. This is a vast AOC with around 1500 different wine-making estates. There are many good AOC Medoc wines, which did belong to the now defunct Cru Bourgois classification. The most notable estate is Potensac, which is owned by Leoville Las Cases.
