Château Langoa Barton is a prestigious Third Growth (Troisième Cru) estate in the Saint-Julien appellation of Bordeaux, France, classified in the historic Bordeaux Wine Official Classification of 1855. The estate has been owned by the Barton family for over 200 years, and the 2021 vintage label commemorates this bicentennial milestone.

The 2021 vintage is a classic Médoc blend composed of 61% Cabernet Sauvignon, 36% Merlot, and 3% Cabernet Franc. The wine undergoes 18 months of élevage in 60% new French oak barrels. On the nose it offers aromas of peppery spice, fresh herbs, and red currants with subtle toast and smokiness. The palate is medium- to full-bodied with ripe yet firm tannins, bright red fruit, and notable freshness—hallmarks of well-structured Saint-Julien Bordeaux. The 2021 received outstanding critical acclaim, earning 95 points from Wine Enthusiast, 94 points from Jeb Dunnuck, and 93 points from Wine Advocate. Recommended drinking window is 2025–2047.
