Château Le Boscq sits in Saint-Estèphe, the northernmost appellation of the Médoc, where gravelly soils and a maritime climate shape wines of structure and depth. The estate produces three principal wines. Its flagship Saint-Estèphe blends Cabernet Sauvignon, Merlot, Petit Verdot, and Cabernet Franc into a wine that reflects the appellation's signature power and mineral tension. Héritage de Le Boscq, a secondary Saint-Estèphe, draws from the same varieties in different proportions, offering a complementary expression. The Vieilles Vignes Médoc, sourced from older vines, incorporates Malbec alongside Merlot, Cabernet Sauvignon, and Cabernet Franc. All three wines have been assessed by Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. Saint-Estèphe as a region favors left-bank Bordeaux structure—firm tannins, dark fruit, and aging potential—and Le Boscq's portfolio reflects that character across its range.
