Tenuta Castelbuono produces wines from Umbria, a region in central Italy known for its distinctive indigenous varieties and structured red wines. The winery focuses on Sagrantino, Umbria's signature grape, which yields wines of depth and complexity. Carapace Montefalco Sagrantino, the winery's flagship, demonstrates the variety's capacity for richness and aging potential. The core range includes Montefalco Sagrantino and Lampante Montefalco Rosso Riserva, a blend of Sagrantino, Sangiovese, Merlot, and Cabernet Sauvignon that reflects both local tradition and broader Italian winemaking. These wines have been evaluated by Wine Spectator and Wine Enthusiast.
