Château Haut-Bernat sits in Puisseguin-Saint-Émilion, the easternmost appellation of Libournais, where clay and limestone soils favor the ripening of Merlot and Cabernet varieties. The winery's Cuvée Vieilles Vignes Croix de Haut Bernat blends Merlot with Cabernet Sauvignon and Cabernet Franc, drawing structure and depth from older vines. The core Puisseguin-Saint-Émilion, built on Merlot and Cabernet Sauvignon, reflects the appellation's character: ripe fruit and supple tannins. Both wines have been assessed by Wine Spectator, Wine Enthusiast, and Wine Advocate.
