Casisano produces Sangiovese-based wines from Montalcino in Tuscany's heart. The winery's portfolio centers on the region's defining expressions: Rosso di Montalcino, a lighter, earlier-drinking interpretation; Brunello di Montalcino, the structured flagship; and Riserva Brunello di Montalcino, aged longer and built for the cellar. Sangiovese in this terroir yields wines of dark fruit and mineral tension, with the aging regimen deepening complexity and tannin refinement. Casisano's releases have been assessed by Wine Spectator, Wine Enthusiast, Decanter, Wine Advocate, and Falstaff, reflecting the precision demanded of serious Montalcino producers.
