Rocche Costamagna produces Nebbiolo-based Barolos from the Rocche dell'Annunziata vineyard in Piemonte's Barolo zone. The winery's flagship offerings—the Bricco Francesco Rocche dell'Annunziata Barolo Riserva and the standard Bricco Francesco bottling—represent the region's signature expression of Nebbiolo's structure and aging potential. A core Barolo rounds out the portfolio. Barolo demands time; Nebbiolo's high tannins and acidity reward patience, often requiring years to reveal the elegance beneath its austere frame. The Rocche dell'Annunziata site, a respected cru within Barolo, contributes specificity to these wines. Prestige critics including Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff have assessed the winery's releases.
