Château La Bastienne sits in Montagne-Saint-Émilion, the northernmost appellation of Saint-Émilion on Bordeaux's Right Bank. The vineyard works primarily with Merlot, the region's signature grape, which thrives in the clay and limestone soils of this corner of Libournais. The winery's flagship, Château La Croix La Bastienne, is a Merlot-based wine that has drawn assessment from Wine Advocate, Decanter, and Wine Enthusiast. A second offering, the Montagne Saint-Émilion blend, combines Merlot with Cabernet Franc and Cabernet Sauvignon—a structure typical of Right Bank Bordeaux. Both wines reflect the appellation's character: ripe fruit, moderate tannin, and the mineral undertones that clay-dominant terroirs impart.
