Giovanni Rosso produces Nebbiolo-based Barolos from Piemonte's most prestigious region. The winery's flagship, Barolo Vigna Rionda Ester Canale, exemplifies the power and structure that define serious Barolo—a wine that has drawn attention from Wine Enthusiast, Wine Advocate, Decanter, Wine Spectator, and Falstaff. The Barolo Ester Canale Rosso and Barolo Cerretta round out the portfolio, each built on the same foundation of Nebbiolo's tannin architecture and mineral complexity. These are wines that demand time in the glass and cellar, reflecting the unforgiving terroir of Barolo's hillside vineyards.
