Castello del Trebbio sits in Chianti, the heart of Tuscan wine country, where Sangiovese has long defined the region's identity. The winery's portfolio spans both traditional expressions and modern blends. Its Vin Santo del Chianti—a fortified wine built from Malvasia and Trebbiano—shows the dried-fruit intensity and oxidative complexity that mark this Tuscan category. The Merlot stands as a varietal statement, while Vigneti Trebbio, a blend of Merlot, Cabernet Franc, Syrah, Sangiovese, and Petit Verdot, reflects the broader Tuscan turn toward international grapes alongside native varieties. Wines from the estate have been assessed by Wine Spectator, Wine Enthusiast, Falstaff, Wine Advocate, and Decanter.
