Château Hosanna deftly marries elegance with depth and could be considered, thanks to the delicate touch of the Cabernet Franc, a feminine counterpart to Château Petrus. While Château Hosanna is unclassified, it has historically been counted among the great crus of the region. The property is situated south of Château Lafleur, west of Château Pétrus and north of Château Vieux Certan. Sharing its origin with Château Vieux Certan and Château Certan-de-May, the estate was once part of the original Certan property, belonging to the de May family before the French Revolution. For a period, the wine was sold as Château Certan-Marzelle, until it was acquired by the Giraud family in 1956, and was renamed Château Certan-Giraud.
