Château Mazeris sits in Canon-Fronsac, a compact appellation within Bordeaux's Libournais region known for structured, mineral-driven reds. The winery produces Canon-Fronsac, a Merlot-based blend anchored by Cabernet Franc and Malbec, with supporting Cabernet Sauvignon and Petit Verdot. This five-grape composition reflects the region's gravelly plateau terrain and cooler microclimates, which favor wines of depth and aging potential. The Canon-Fronsac has been assessed by Wine Spectator, Wine Enthusiast, and Decanter.
