Manzone produces wines from Piemonte in northern Italy, drawing on the region's tradition of elegant, structured reds and distinctive whites. The winery's portfolio centers on Nebbiolo, the noble grape behind its Castelletto and Gramolere Barolo Riserva—both expressions of the variety's characteristic tannin architecture and aging potential. Alongside these classical offerings sits Rosserto, a Rossese Bianco that showcases the region's capacity for mineral-driven white wines. Decanter, Wine Spectator, Wine Advocate, Wine Enthusiast, and Falstaff have all assessed the winery's releases, reflecting their standing within Piemonte's quality framework.
