Château Terrasson sits in Côtes de Bordeaux, the southern reaches of Bordeaux where clay and limestone soils shape wines of mineral precision and dark fruit depth. The region favors Cabernet Franc, Cabernet Sauvignon, and Merlot—grapes that thrive in this cooler pocket, yielding structured reds with earthy backbone. The winery's Cuvée Prévenche Castillon, a blend of these three varieties, demonstrates the character of the appellation: a wine built on acidity and tannin rather than opulence, with the kind of frame that rewards patience. Wine Spectator has assessed the winery's output, recognizing the precision of its approach to this undervalued corner of Bordeaux.
