Franco M. Martinetti produces wines from Piemonte, the northern Italian region celebrated for its powerful reds and distinctive terroir. The winery's portfolio centers on Nebbiolo, Barbera, and Cabernet Sauvignon—grapes that thrive in the region's continental climate and limestone-rich soils. The Marasco Riserva Barolo, made from Nebbiolo, represents the winery's work with one of Italy's most demanding varietals, known for its structure and aging potential. Sul Bric Monferrato Rosso blends Cabernet Sauvignon and Barbera, capturing the region's tradition of combining local and international varieties. The Montruc Barbera d'Asti Superiore showcases Barbera, a grape that defines much of Piemonte's identity—offering bright acidity and dark fruit character. These wines have been assessed by major critics including Wine Spectator, Wine Advocate, Falstaff, Wine Enthusiast, and Decanter.
