Château Cassagne Haut-Canon produces wines from Canon Fronsac, a Bordeaux appellation defined by its right-bank terroir and structured red blends. The estate's portfolio centers on Merlot-based wines with supporting roles for Cabernet Franc, Malbec, Petit Verdot, and Cabernet Sauvignon—a classical Bordeaux mix that reflects the region's clay and iron-rich soils. La Truffière Canon Fronsac, the flagship, layers these varieties into a wine that has drawn assessment from Wine Spectator and Wine Advocate. The Canon Fronsac and Les Terrasses Canon-Fronsac offerings follow, each built on the same varietal foundation but expressing different facets of the appellation's character. Canon Fronsac itself occupies a distinct position within Bordeaux's right bank: less celebrated than Pomerol or Saint-Émilion, but capable of producing age-worthy wines with depth and mineral precision. The winery's focus on this smaller, less-trafficked appellation positions it within a tradition of serious, undervalued Bordeaux production.
