Vietti has the enormous advantage of 10 MGA sites at its disposition for blending purposes (and for making single-vineyard wines). This allows them to select the fruit they want to best express any one vintage. The 2018 Barolo Castiglione draws upon those 10 sites (including the recent additions of Mosconi, Ginestra, Bricco Ravera and Briccolina) to make what is ultimately its best-selling wine (with 35,000 bottles released). This classic rendition is tonic and clean with varietal tones of wild berry, rose and rusty nail.
