Silvio Grasso produces Nebbiolo-based Barolos from Piemonte in Northern Italy. The winery's portfolio centers on single-vineyard expressions: Annunziata Vigna Plicotti and Ciabot Manzoni both achieve an average prestige rating of 92.0, while Pì Vigne reaches 91.6. These wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, Decanter, and Falstaff. Barolo, the region's most structured red, demands Nebbiolo's tannins and acidity to develop complexity over time. Silvio Grasso's vineyard-specific approach reflects the Piedmontese tradition of terroir-driven winemaking, where site distinction shapes the final expression of this demanding grape.
