Château Gréteau produces wines from Bordeaux, the classic French region where Cabernet Franc, Merlot, and Cabernet Sauvignon form the backbone of its portfolio. The winery's Bordeaux bottling—a blend of these three varieties—represents its core expression, earning recognition from Wine Enthusiast and Wine Spectator. A Bordeaux Supérieur follows, emphasizing Merlot and Cabernet Sauvignon with Cabernet Franc in support. Both wines reflect the region's tradition of structured, age-worthy blends built on the interplay between Cabernet's tannin and Merlot's roundness. The prestige critics' assessments place the standard Bordeaux at the higher end of the range, suggesting a wine of substance and balance. Gréteau's output centers on these two tiers, each calibrated to the specific regulations and character of its appellation.
