Clos du Marquis is a distinguished red Bordeaux wine from the Saint-Julien appellation in the Médoc region of France. The 2021 vintage is produced by the renowned Léoville Las Cases estate and is grown from a designated single vineyard, making it a wine of its own identity rather than a secondary label. It is a classic Left Bank Bordeaux blend composed of approximately 70% Cabernet Sauvignon, 20% Merlot, and the balance from Cabernet Franc and Petit Verdot.

The wine is celebrated for its elegantly structured tannins, vibrant acidity, and expressive aromatics of dark cassis, blackberry, plum, graphite, cedar, and spring flowers. Secondary notes often include cinnamon, vanilla, cocoa, and a touch of minerals. On the palate it is rich yet firmly structured, offering classic Saint-Julien finesse with a long, polished finish. This wine benefits from decanting and has strong aging potential, developing further complexity over a decade or more in the cellar. Pairs beautifully with grilled lamb, roasted beef, and aged cheeses.
