Mario Costa
Mario Costa operates in Barbera d'Alba, in Piemonte's Roero zone, where Nebbiolo and Arneis thrive on the region's distinctive sandy soils. The winery's Roero Riserva Morinaldo, built from Nebbiolo, demonstrates the grape's capacity for structure and aging potential in this northern Italian terroir. Alongside it, two Arneis expressions—the Roero Arneis and Miladui Roero Arneis—showcase the white variety's mineral character and aromatic profile, hallmarks of the zone. The wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, and Decanter, reflecting their standing within the region's quality framework. Roero's combination of elevation, soil composition, and continental climate produces wines marked by precision and definition rather than ripeness alone.
