The red grape variety comes from Italy. Synonyms are Gropel, Gropel Nones, Groppello Anaune, Groppello Nonesiano and Nosiola Nero. Groppello (Gropel, Gropello or similar) is the name given to several independent varieties in Northern Italy. The name is derived from "Gropo", which in a local dialect means "knot" after the appearance of the grapes. The parentage (parenthood) is unknown. Despite synonyms or morphological similarities that seem to indicate it, it must not be confused with the varieties Groppello dei Berici, Groppello di Mocasina, Groppello Gentile or Pignola Valtellinese (Groppello di Breganze). According to DNA analyses carried out in 2007, Groppello di Revò is a direct descendant of the Valaisan variety Rèze. As Rèze is also a parent of the Nosiola variety, this explains its synonym Groppello Bianco. According to one hypothesis, it is said to be a descendant of the Uva raetica mentioned by Pliny the Elder (23-79), from which the ancient wine Raeticum was made. The late ripening vine is resistant to frost. It is cultivated exclusively in Val di Non (Non Valley) in the Trentino area (Trentino-Alto Adige). In 2016, 12 hectares of vineyards were designated (Kym Anderson).
