The name Vespolina comes from the fact that wasps (vespe in Italian) look for this grape for its sweetness. It lost importance with the advent of phylloxera, it matured irregularly when the plants were grafted on american rootstocks. Nowadays, with the improvement and availability of the rootstocks, this defect has greatly attenuated. The first descriptions were made by Acerbi (1885), followed by Galleso (1889), who called it Vitis vinifera Circumpadana. In Lombardy it is known almost exclusively with the name of Ughetta di Canneto, from the name of the village of Canneto Pavese where it is widely cultivated; someone believe that it is a different variety developed locally.
