Ruggeri produces Prosecco in Conegliano-Valdobbiadene, the northeastern Italian region where Glera thrives on steep, terraced hillsides. The winery's portfolio centers on this native variety and its regional expressions—from the pure Glera of Ladaltempo to the field-blend complexity of Vecchie Viti, which incorporates Perera, Verdiso, and Bianchetta Trevigiana alongside Glera. Valdobbiadene Superiore di Cartizze Dry, a single-vineyard Glera from the appellation's most prestigious cru, represents the precision and mineral character the zone is capable of. Prosecco from this region is marked by delicate fruit, crisp acidity, and the subtle yeast complexity that comes from the Charmat method. Decanter, Falstaff, Wine Enthusiast, Wine Spectator, and Wine Advocate have all assessed Ruggeri's releases.
