Marco Felluga produces wines from Friuli-Venezia Giulia in northeastern Italy, a region celebrated for crisp whites and structured reds. The winery's portfolio centers on Collio-designated bottlings that reflect the area's mineral-rich terroir and continental climate. The Mongris Collio Pinot Grigio Riserva exemplifies the region's signature expression of the variety—precise and layered. Alongside white-focused production, Marco Felluga crafts red wines including Collio Cabernet Sauvignon and Collio Rosso, demonstrating range across the winery's range. Wines from the estate have been reviewed by Wine Spectator, Wine Enthusiast, and Wine Advocate.
