Diego Morra produces Nebbiolo-based Barolos in Piemonte, northern Italy's most prestigious red wine region. The winery's portfolio centers on site-specific expressions of this demanding grape, which demands cool hillside vineyards and years of aging to reveal its characteristic structure and complexity. Barolo Monvigliero stands as the flagship, followed by the core Barolo and Barolo Zinzasco—each a distinct interpretation of Nebbiolo's potential within the appellation's microclimates. Decanter and Wine Enthusiast have rated across the range, with Monvigliero achieving particular recognition. These are serious, age-worthy wines rooted in Piemonte's tradition of extracting elegance and power from a single, unforgiving variety.
