Château Fongaban produces wines from Puisseguin-Saint-Émilion, a satellite appellation within Saint-Émilion on Bordeaux's Right Bank. The flagship Puisseguin-Saint-Émilion blends Merlot with Cabernet Franc, Petit Verdot, and Cabernet Sauvignon—a structure typical of the region's clay and limestone soils. A secondary offering from Castillon—Côtes de Bordeaux combines Merlot, Cabernet Franc, and Cabernet Sauvignon. Both wines have been assessed by Wine Enthusiast and Wine Spectator.
