Château Saint-Michel produces wines from Bordeaux Supérieur, the region's elevated tier of classification. The flagship Bordeaux Supérieur blends Cabernet Franc and Merlot, anchoring the portfolio with structure and depth. A Lussac-Saint-Emilion, built from Cabernet Sauvignon, Merlot, and Cabernet Franc, rounds out the range. Wine Spectator has rated the winery's output. The Bordeaux Supérieur designation reflects stricter production rules than standard Bordeaux—lower yields, higher alcohol minimums, longer aging—which shape the character of wines from this appellation. Cabernet Franc and Merlot form the backbone of the Right Bank style, offering dark fruit, tannin, and the mineral undertones typical of the region.
