Sesti produces Sangiovese-based wines from Toscana in central Italy. The winery's portfolio centers on Brunello di Montalcino, the region's flagship expression of Sangiovese. The Phenomena Brunello di Montalcino Riserva and Grangiovese represent the upper range of the lineup, both Sangiovese bottlings that have drawn assessment from major critics including Wine Spectator, Decanter, Wine Enthusiast, Falstaff, and Wine Advocate. The standard Brunello di Montalcino rounds out the core range. Montalcino's elevation and continental climate shape wines of structure and aging potential—hallmarks of the appellation's finest examples. Sesti's focus remains on the varietal's expression across different vineyard selections and reserve designations.
