The blend of Château Haut-Marbuzet is based primarily on three classic Bordeaux grape varieties: Cabernet Sauvignon, Merlot and Cabernet Franc. The proportion of Merlot has historically been higher than in many properties in the Médoc, which largely explains the characteristic roundness and softness of the wine. This blending choice, combined with a terroir of well-drained clay-limestone gravels on the slopes of Saint-Estèphe, allows the château to produce a wine that is both structured and indulgent, true to its reputation as a pleasure-driven Saint-Estèphe.
