Prugnolo is the name of a mountain shrub found on the perimeter of the vineyards with bluish-purplish berries that ripen just about the same time the grapevines do. A blend of Nebbiolo from various parcels, the Rainoldi 2017 Valtellina Superiore Prugnolo is a deceptively light and streamlined wine that in fact offers good length and finish. The wine opens to a light ruby color, and the bouquet dances with wild berries, blue violets and crushed stone. This 2017 vintage, in a release of about 8,800 bottles, offers some tannic crunch or firmness that makes this a good partner to the local slow-cooked beef dish, manzo alla valtellinese. This is a terrific, well-priced bottle for a snowy night by the fireplace.
