Teruzzi produces wines in San Gimignano, the medieval hilltop town in Toscana known for its distinctive white wines. The winery focuses on Vernaccia di San Gimignano, the region's signature variety—a crisp, mineral-driven white with structure and aging potential. The Vernaccia di San Gimignano Riserva and Sant'Elena Vernaccia di San Gimignano Riserva showcase the grape's ability to develop complexity over time. Teruzzi also makes Arcidiavolo, a red blend combining Alicante Bouschet, Sangiovese, Cabernet Sauvignon, and Petit Verdot, demonstrating range beyond the region's white-wine reputation. The winery's portfolio has been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff.
