Mamete Prevostini produces Nebbiolo-based wines from Lombardia in Northern Italy, a region celebrated for its alpine terrain and mineral-driven expressions of this demanding variety. The winery's portfolio centers on Valtellina's distinctive interpretations: Marena Sassella, Valtellina Superiore Riserva, and Corte di Cama Sforzato di Valtellina each showcase Nebbiolo's capacity for structure and complexity at elevation. These wines have been assessed by Wine Spectator, Wine Advocate, and Wine Enthusiast. Valtellina's steep vineyards and continental climate impose rigor on the grape, yielding wines marked by tannin architecture and aromatic intensity rather than opulence. Nebbiolo here expresses itself with precision—high acidity, floral notes, and the mineral signature of limestone-rich soils. Mamete Prevostini's focus on single-vineyard and reserve expressions reflects the granular terroir distinctions that define serious Valtellina production.
