Costaruél produces Prosecco from the Prosecco di Treviso zone in Veneto, where the Glera grape thrives in the region's limestone-rich hills. The winery's Conegliano Valdobbiadene Prosecco Superiore Extra Dry balances the varietal's characteristic stone fruit and floral notes with crisp acidity and fine perlage. A second expression, Le Dolcirive Conegliano-Valdobbiadene Prosecco Superiore Extra Dry, offers similar precision in a distinct bottling. The winery also produces Le Dolcirive Rosé Extra Dry, extending its range beyond the traditional white. Wine Enthusiast has rated these releases. Prosecco di Treviso sits at the heart of Italy's sparkling wine production, and Costaruél's focus on the Extra Dry style—drier than many Proseccos—reflects the contemporary preference for lower residual sugar and food-friendly acidity.
