Viberti Giovanni produces Nebbiolo-based Barolos from the Monvigliero and Ravera vineyard sites in Piemonte's Barolo zone. The Monvigliero Barolo and Ravera Riserva Barolo represent the winery's core expression of the region's signature variety—wines that have drawn assessment from Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter. The portfolio extends beyond Nebbiolo to include a Langhe Chardonnay, offering a white counterpoint to the structured reds of the Barolo appellation. Northern Italy's continental climate and the limestone-rich soils of the Langhe hills shape the character of these wines, where Nebbiolo's tannin structure and aromatic complexity define the category.
