Rizieri produces Nebbiolo-based wines from Piemonte in northern Italy, where the grape reaches its most structured and age-worthy expression. The winery's portfolio centers on Barolo and its regional sibling Nebbiolo d'Alba—both wines that showcase the variety's signature tannin architecture and capacity for complexity. Silio Barolo, the flagship offering, demonstrates the depth possible within the appellation. Nebbiolo in this region demands patience; these are wines built for the cellar, their initial austerity gradually giving way to leather, tar, and dried cherry notes over years. The distinction between Barolo proper and Nebbiolo d'Alba lies partly in terroir and partly in regulation: Barolo commands stricter production rules and longer aging requirements, while Nebbiolo d'Alba offers a more approachable entry point to the variety. Rizieri's wines have been assessed by major critics including Wine Advocate, Decanter, Wine Enthusiast, Wine Spectator, and Falstaff. For collectors seeking traditional Piemontese Nebbiolo, these bottlings represent the region's uncompromising approach to winemaking.
