Primosic produces wines from Collio, the northeastern Italian region celebrated for its mineral-driven whites and elegant reds. The winery's portfolio centers on the distinctive grapes of Friuli-Venezia Giulia: Chardonnay, Sauvignon Blanc, Friulano, and Ribolla Gialla, alongside Merlot. Klin, a white blend of Chardonnay, Ribolla Gialla, Sauvignon Blanc, and Friulano, stands as a flagship expression of the region's terroir, earning recognition from Wine Spectator, Wine Enthusiast, Wine Advocate, Falstaff, and Decanter. The winery's Merlot and Chardonnay have similarly drawn attention from major critics. Collio's cool continental climate and limestone-rich soils shape wines of precision and structure—whites with aromatic intensity and mineral tension, reds with poise and depth. Primosic's work reflects the region's commitment to expressing place through both indigenous and international varieties.
