The white grape variety (also Verdetto) originates from Italy. Despite seemingly suggestive synonyms or morphological or name similarities, it must not be confused with the varieties listed below. The variety originates from the region of Umbria, where it was first mentioned in documents in Orvieto in 1894. In the VIVC catalogue, however, it is not listed as an independent variety called Verdello, but only as a synonym for the white varieties Beba, Godello, Trajadura (Verdello Rubio), Verdelho, Verdello di Bracciano, Verdicchio Bianco and Verdone Bianco. The late-ripening vine is susceptible to fungal diseases such as powdery mildew, downy mildew and botrytis. It produces white wines with high acidity. The variety is mainly cultivated in Umbria, where it is permitted 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 vineyards were reported under the name Verdello in Italy, with a strong downward trend (Kym Anderson statistics).
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
