Marchesi Alfieri produces wines from Piemonte in northern Italy, where Nebbiolo and Barbera thrive in demanding terroir. The winery's Costa Quaglia Nebbiolo Terre Alfieri expresses the region's signature structure and complexity, while its Barbera offerings—Alfiera Barbera d'Asti Superiore and La Tota Barbera d'Asti—showcase the variety's dark fruit and acidity across different expressions. These wines have been assessed by Decanter, Wine Spectator, Wine Enthusiast, Wine Advocate, and Falstaff. Piemonte's continental climate and limestone-rich soils demand precision in the vineyard and cellar; the winery's portfolio reflects that rigor, with each wine calibrated to its specific site and varietal character.
