Le Bertille operates in Montepulciano, the southeastern corner of Tuscany where Sangiovese reaches particular intensity and structure. The winery's core expression is Vino Nobile di Montepulciano, a blend anchored in Sangiovese with supporting Colorino del Valdarno, Ciliegiolo, and Canaiolo Nero—a traditional composition that reflects the region's viticultural identity. The Riserva designation signals extended aging, deepening the wine's complexity. A younger Rosso di Montepulciano offers earlier approachability, drawing from the same varietal palette in lighter proportions. All three wines have been assessed by major critics including Wine Advocate, Wine Spectator, Decanter, Wine Enthusiast, and Falstaff. The winery's portfolio demonstrates the range available within Montepulciano's regulated framework, from entry-level expression to aged reserve.
