Château du Courlat sits in Lussac-Saint-Émilion, the northernmost appellation of the Saint-Émilion plateau in Bordeaux's Libournais region. The vineyard produces two principal wines: a Lussac-Saint-Émilion built on Merlot, Cabernet Sauvignon, and Cabernet Franc, and a Cuvée Jean-Baptiste that emphasizes Cabernet Franc alongside Merlot. Both have been assessed by Decanter, Wine Advocate, Wine Spectator, and Wine Enthusiast. The primary Lussac-Saint-Émilion expresses the region's characteristic blend of ripe dark fruit and structured tannin, while the Cuvée Jean-Baptiste leans toward the mineral precision and herbal notes that Cabernet Franc brings to the Right Bank. Lussac-Saint-Émilion itself is known for clay and limestone soils that favor Merlot's ripeness without sacrificing freshness—a balance the estate achieves across its range.
