Case Bianche produces Prosecco in Conegliano-Valdobbiadene, the northeastern Italian region where Glera thrives on steep, terraced hillsides. The winery's core releases—Prosecco di Conegliano Valdobbiadene Superiore Extra Dry and Vigna del Cuc Conegliano Valdobbiadene Prosecco Superiore Brut—showcase the grape's characteristic brightness and minerality. The Extra Dry expression relies on pure Glera, while Vigna del Cuc adds Chardonnay for textural complexity. A third offering, Antico Prosecco Conegliano Valdobbiadene, rounds the portfolio. Wine Enthusiast, Wine Spectator, and Wine Advocate have all assessed the winery's output. Prosecco from this appellation is known for its aromatic profile and crisp acidity—qualities that define the category across producers working this terrain.
