Château Langoa Barton is a winery and vineyard in the Saint-Julien appelation of the Médoc. In the official 1855 Bordeaux classification it was ranked as a third growth. Like many wines made in the area, Langoa Barton is Cabernet Sauvignon-dominant, but with more Merlot than its adjacent sibling estate, Léoville Barton. Somewhat confusingly, the château features on the label of Léoville Barton – which has no château building or winery of its own – but not on Langoa's. In 1821, Anglo-Irish wine merchant Hugh Barton bought Château Langoa and a portion of the Léoville estate which became Léoville Barton. Anthony Barton inherited the two properties from his uncle Ronald in 1983.
