The white grape variety (also Verdetto) originates from Italy. Despite seemingly indicating synonyms or morphological or name similarities, it must not be confused with the varieties Godello (synonym Verdelho), Pedro Ximénez (synonym Verdello), Verdejo, Verdelho, Verdello di Bracciano or Verdicchio Bianco (synonym Verdetto). The variety originates from the Umbria region, where it was first mentioned in documents in Orvieto in 1894. In any case, the VIVC catalogue does not list an independent variety called Verdello, but only as a synonym for Verdicchio Bianco. The late-ripening vine is susceptible to fungal diseases like powdery and downy mildew as well as botrytis. It yields white wines with high acidity. The variety is mainly cultivated in Umbria, where it is allowed in the DOC wines Colli del Trasimeno, Orvieto and Torgiano, among others. There are further stocks in Tuscany (DOC wine Bianco di Pitigliano) and Sicily. In 2016, 179 hectares of vines were reported under the Verdello name in Italy, with a sharp downward trend (Kym Anderson statistics).
