San Polo produces Brunello di Montalcino in Tuscany's Montalcino zone, where Sangiovese reaches its most structured expression. The winery's portfolio centers on three flagship releases: Vignavecchia Brunello di Montalcino and Podernovi Brunello di Montalcino, both pure Sangiovese, alongside a Brunello di Montalcino Riserva. These wines have been assessed by Wine Spectator, Decanter, Wine Advocate, Wine Enthusiast, and Falstaff. Brunello di Montalcino demands extended aging and barrel time—a demanding protocol that shapes wines of considerable tannin and aging potential. San Polo's approach reflects the region's commitment to Sangiovese as the sole permitted variety, a discipline that has defined central Tuscan winemaking for centuries. The wines demonstrate the characteristic architecture of the appellation: dark fruit, earthy undertones, and the mineral tension that emerges from Montalcino's limestone-rich soils.
