Château Castera produces wines from the Médoc, Bordeaux's left-bank stronghold of structured reds. The estate's portfolio centers on Merlot-based blends anchored by Cabernet Sauvignon, Cabernet Franc, and Petit Verdot—the classic Médoc framework. Les Essais Médoc, the flagship, layers these five varieties into a wine that has drawn attention from Wine Advocate, Wine Enthusiast, Decanter, and Wine Spectator. Apostrophe Cuvée Castera offers a more focused blend of Merlot, Cabernet Sauvignon, and Petit Verdot. The core Médoc bottling rounds out the range, balancing the same core grapes with similar critical recognition. Each wine reflects the Médoc's signature balance of power and refinement, built on the region's gravelly soils and maritime influence.
