Borgo del Tiglio produces white wines from Collio, the limestone-rich region of Friuli-Venezia Giulia in northeastern Italy. The winery's portfolio centers on the aromatic and mineral-driven varieties native to this terroir: Friulano, Malvasia, Riesling, and Sauvignon Blanc. Collio Ronco della Chiesa, a single-vineyard Friulano, and Collio Malvasia Selezione represent the winery's precision with indigenous grapes, both earning ratings of 93 from prestige critics including Wine Enthusiast, Wine Advocate, Wine Spectator, and Falstaff. Collio Studio di Bianco, a white blend of Riesling, Friulano, and Sauvignon Blanc, demonstrates the winery's approach to combining the region's signature varieties, rated 92.9 by the same panel. These wines reflect the distinctive character of Collio's cool climate and calcareous soils, which impart freshness and complexity to the whites produced here.
