L'Antica Quercia operates in Veneto, the northeastern Italian region that defines modern Prosecco. The winery focuses on Glera, the varietal at the heart of the region's sparkling tradition. Its flagship 'A' Conegliano-Valdobbiadene Prosecco Superiore represents the upper tier of the appellation—a designation reserved for wines of stricter production standards and longer aging. The Prosecco Brut and Matiú Prosecco di Conegliano Brut round out the portfolio, each built from the same grape but expressing the nuances of their specific terroirs. Decanter, Wine Enthusiast, and Wine Advocate have all assessed the winery's releases, reflecting the critical attention these wines command in the broader market.
