Verdello is a white Italian wine grape variety that is grown mostly in the Umbria region of central Italy where it plays a minor role as a blending grape in several Denominazione di Origine Controllata (DOC) wines, including Orvieto. Despite similarities in their names, the Italian Verdello grape has no close genetic relationship with the Portuguese wine grape Verdelho that is grown on the islands of Madeira and Azores. However, like the Portuguese grape, Verdello's name likely comes from the dark green color of its berries before veraison.[1]
