Carlo Giacosa produces Nebbiolo-based Barbarescos from Piemonte in Northern Italy. The winery's portfolio centers on single-vineyard expressions: Ovello Barbaresco, Luca Barbaresco Riserva, and Asili Barbaresco. Barbaresco, one of Italy's most prestigious red wine regions, yields Nebbiolo grapes that develop into wines of structure and complexity, marked by tannin and acidity that reward patience. These three bottlings have been assessed by Decanter, Wine Enthusiast, Wine Advocate, Wine Spectator, and Falstaff. The Ovello and Luca Riserva sit at the upper end of critical evaluation, while Asili rounds out a focused range rooted in the terroir of specific vineyard sites. Carlo Giacosa's approach emphasizes the distinction between its named crus, allowing the character of each parcel to emerge through the lens of Nebbiolo.
