Château Sirac sits in Côtes de Bourg, a compact appellation within Bordeaux's right bank where clay and limestone soils favor Merlot-based blends. The estate produces a Côtes de Bourg that marries Merlot and Cabernet Sauvignon—a pairing typical of the region, where the former provides structure and dark fruit while the latter adds backbone and aging potential. Wine Enthusiast has rated the wine at 88 points. Côtes de Bourg itself remains one of Bordeaux's less heralded territories, a fact that often translates to thoughtful winemaking without the commercial pressure of grander appellations. The wines reflect the terroir's character: approachable, balanced, and built for the table rather than the trophy shelf.
