Castellari Bergaglio produces Cortese-based wines from Gavi, the crisp white heartland of Piemonte in northern Italy. The region's limestone-rich soils and cool microclimate shape wines of mineral precision and bright acidity. The winery's portfolio centers on three expressions of this single varietal: Salluvii Gavi, Fornaci Gavi di Tassarolo, and Pilin Gavi. Each captures the distinctive character of Gavi's terroir—a lean, food-friendly white with citrus and stone-fruit notes, structured by the grape's natural acidity. Wine Enthusiast and Wine Spectator have rated these releases, recognizing their dry, elegant profile. Cortese thrives in this corner of Piemonte, where it achieves a balance between freshness and subtle complexity that makes these wines versatile at table.
