Château La Fleur de Gay is planted to 91% old vine Merlot and 9% Cabernet Franc. This is different than the original plantings which started out as 100% Merlot. The vines are planted in a specific, small, 2-hectare portion of the best parcel that belongs to Chateau La Croix de Gay.
The terroir is mostly gravel with clay soils on slopes that rise to 38 meters at their peak. Chateau La Fleur de Gay has very good neighbors. The Right Bank chateau is not located far from Chateau Clinet or L'Eglise Clinet on the edge of the Pomerol Plateau.
