Col d'Orcia produces Sangiovese-based wines from Montalcino in Tuscany's heart. The winery's flagship Nastagio Brunello di Montalcino expresses the region's signature structure and earthy depth, while the Poggio Al Vento Brunello di Montalcino Riserva demonstrates the intensity that extended aging can draw from the varietal. A Cabernet Sauvignon offering, Olmaia Sant'Antimo, rounds the portfolio with a different expression of Tuscan terroir. These wines have drawn assessment from Decanter, Wine Enthusiast, Wine Spectator, Wine Advocate, and Falstaff. Brunello di Montalcino remains one of Italy's most demanding designations—a wine of power and refinement that requires time to reveal its architecture. Col d'Orcia's approach centers on the Sangiovese grape, which in this zone yields wines of dark fruit, tannin grip, and the mineral undertones characteristic of southern Tuscany.
