Château Puy Guilhem produces wines from Bordeaux's right bank, where clay and iron-rich soils shape dense, structured reds. The winery's Fronsac—a blend of Cabernet Franc, Merlot, and Malbec—expresses the appellation's characteristic earthiness and dark fruit intensity. Its Château Canon Guilhem Canon-Fronsac, built from Petit Verdot, Merlot, and Cabernet Sauvignon, shows the power and aging potential of the Canon-Fronsac plateau. Both wines have been assessed by Wine Advocate, Decanter, and Wine Spectator. Fronsac's blend emphasizes the region's preference for Cabernet Franc's herbal spine and Merlot's roundness, while the Canon-Fronsac selection tilts toward Petit Verdot's tannin architecture. These are wines of the right bank's cooler microclimates—wines that demand time and food.
