Nanni operates in Salta, Argentina's high-altitude wine region, where cool nights and intense sun create conditions suited to bold reds and aromatic whites. The winery produces Malbec and Torrontés, two grapes that define the region's character. Its Malbec—dark-fruited and structured—has drawn attention from Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. The Torrontés, a white varietal native to Argentina, offers the floral and citrus notes typical of the grape, and has similarly engaged prestige critics. Both wines reflect Salta's terroir: elevation that slows ripening and concentrates flavor, altitude that sharpens acidity. Nanni's focus on these two varieties positions it within the region's core identity.
