Deltetto is a Piemonte producer working with the region's signature varieties in Roero and Barolo. The winery's portfolio centers on Nebbiolo—the demanding, structured grape that defines the hills south of Alba—and Arneis, Piemonte's white counterpart, known for its mineral precision and aromatic intensity. The Barolo Bussia and Barolo Parussi represent the winery's engagement with Nebbiolo's complexity: wines built on the variety's characteristic tannin architecture and capacity for aging. The Daivej Roero Arneis showcases the white side of the region's terroir. Wines from Deltetto have been assessed by Wine Enthusiast, Decanter, Wine Advocate, Wine Spectator, and Falstaff.
