Conti Costanti produces Sangiovese-based wines from Montalcino in Tuscany's heart. The winery's core expressions—Brunello di Montalcino, Brunello di Montalcino Riserva, and Vermiglio Rosso di Montalcino—reflect the region's volcanic soils and continental climate. Brunello di Montalcino, the appellation's flagship, demands five years of aging before release; Conti Costanti's version balances the variety's characteristic structure with dark fruit and mineral tension. The Riserva designation signals additional barrel time and selection, deepening complexity. Vermiglio, a younger Sangiovese expression, offers earlier accessibility while maintaining the varietal's signature tannin framework. These wines have been assessed by Wine Advocate, Wine Spectator, Decanter, Wine Enthusiast, and Falstaff. Montalcino's elevation and clay-limestone composition yield Sangiovese of particular finesse—wines that age gracefully and reward patience.
