Cascina Castlet sits in Asti, the heart of Piemonte's rolling hills, where Barbera thrives in clay-rich soils and continental conditions. The winery produces Litina and Passum, both Barbera d'Asti Superiore—wines that capture the variety's signature structure: dark cherry, bracing acidity, and mineral grip. These expressions have drawn assessment from Falstaff, Wine Spectator, Wine Enthusiast, Decanter, and Wine Advocate. The winery also makes Uceline, a Monferrato Rosso built on Uvalino, a local variety that adds textural depth to the regional portfolio. Cascina Castlet's work reflects the precision and terroir-focus that define serious Piemontese production.
