Château Perenne produces wines from Blaye-Côtes de Bordeaux, the right-bank appellations of Bordeaux known for structured reds built on Merlot and Cabernet Sauvignon. The winery's flagship, Croix de Perenne Blaye Côtes de Bordeaux, blends Cabernet Franc, Malbec, Merlot, and Cabernet Sauvignon into a wine rated 89.3 by prestige critics including Wine Advocate, Wine Spectator, and Decanter. The core Blaye-Côtes de Bordeaux offering—a Merlot and Cabernet Sauvignon blend—scores 87.0 across the same critical panel. Château Perenne-Magrez Saint-Martin, a Malbec-led blend with Merlot and Cabernet Sauvignon, rounds the portfolio at 86.0. These wines reflect the terroir of Blaye, where clay and limestone soils yield wines of weight and dark-fruit character, anchored by the region's signature Merlot-forward approach.
