This variety is named for the commune of Viadana, in the province of Mantova, as it is mostly found there and in the lower plains of Reggio Emilia province. It’s also known as Groppello Ruberti in honour of the agronomist, Ugo Rubelli, who discovered and propagated it in the late 19th century. It produces ruby red wines with good acidity and tannins, and the typical notes of cherry, sour cherry, blackberry and violets.
