Château Lanessan sits in Haut-Médoc, the central plateau of Bordeaux's Left Bank, where gravelly soils and a maritime climate shape wines of structure and depth. The winery produces two principal expressions: a Haut-Médoc built from Merlot, Cabernet Franc, and Cabernet Sauvignon, and Voyage de Lanessan, a blend of Cabernet Franc, Cabernet Sauvignon, and Merlot. Both wines have been assessed by Wine Enthusiast, Decanter, Wine Spectator, and Wine Advocate. The region's signature style—Cabernet-forward blends with the textural weight of Merlot—defines the house's approach to the appellation.
