Château Castenet produces wines from Bordeaux, the world's most prestigious red wine region. The winery's Entre-deux-Mers blends Sauvignon Blanc, Sémillon, and Muscadelle into a white of mineral precision and aromatic lift—a classic expression of the region's right-bank whites. Its Bordeaux Supérieur marries Merlot and Cabernet Sauvignon, the foundational pairing of the appellation, into a structured red. Both wines have been assessed by Wine Enthusiast, Wine Spectator, and Wine Advocate. The Entre-deux-Mers earned an average prestige rating of 86.1, while the Bordeaux Supérieur averaged 85.0—scores that reflect the technical competence and balance characteristic of serious Bordeaux production.
