Marco Porello works in Piemonte's Roero zone, a region celebrated for its distinctive white varieties and lighter reds. The winery's portfolio centers on Arneis, the local white grape that defines the area's character—mineral, crisp, and food-friendly. The Roero Arneis and Camestrì Roero Arneis showcase the variety's range across different vineyard expressions. Birbet, made from Brachetto, rounds out the range with the region's characteristic light red style. These wines have been assessed by major critics including Falstaff, Wine Advocate, Wine Enthusiast, Wine Spectator, and Decanter, reflecting their standing within Piemonte's serious winemaking tradition.
