Ca'Viola produces Nebbiolo-based Barolos from Piemonte in northern Italy. The winery's portfolio centers on expressions from specific vineyard sites: Sottocastello di Novello, offered in both standard and Riserva bottlings, and Caviòt. The Riserva represents the upper tier of the range, with the standard Sottocastello di Novello and Caviòt offerings providing entry points to the winery's style. Barolo, made from Nebbiolo, is known for its structure, tannin architecture, and capacity to age. Ca'Viola's wines have been assessed by Wine Advocate, Wine Spectator, Decanter, and Wine Enthusiast.
