Spagnol produces Prosecco from Veneto's Valdobbiadene region, where the Glera grape thrives on steep hillside terrain. The winery's portfolio centers on three expressions: Col del Sas Valdobbiadene Extra Dry, Rive di Solighetto Valdobbiadene, and Valdobbiadene Prosecco Superiore. Each represents the dry, mineral-driven character that defines quality Prosecco—crisp acidity, delicate stone fruit, and the subtle complexity that emerges from the region's limestone-rich soils. Wine Advocate, Wine Enthusiast, Falstaff, and Decanter have all assessed the range. The Extra Dry bottling leads the portfolio in prestige critic evaluation, followed by the Rive di Solighetto expression. These are wines built on terroir and precision rather than dosage.
