Castelli Martinozzi produces Sangiovese-based wines from Montalcino in Tuscany's heart. The winery's portfolio centers on the region's defining expressions: Brunello di Montalcino, the structured, age-worthy benchmark of Central Italian viticulture, and its younger sibling Rosso di Montalcino, which captures similar character with earlier approachability. The Brunello di Montalcino Riserva represents the top tier—a wine of depth and complexity shaped by extended aging in wood and bottle. Sangiovese from this terroir displays the variety's hallmark structure: firm tannins, bright acidity, and red-fruit aromatics that evolve with time. The wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff, reflecting their standing within serious wine criticism. Castelli Martinozzi's range offers entry through Rosso and progression into the more demanding, rewarding architecture of Brunello—a classic Montalcino trajectory.
