The white grape variety comes from Italy. Synonyms are Durel, Durella, Durello, Durola Veronese, Groppello Bianco, Nosella, Nosellara, Nosilla, Nosiola Gentile, Nusiola, Nusiola Gentile, Asparagus, Sparger and Spatula. It must not be confused with the Durella variety, even if it appears to have synonyms or morphological similarities. According to DNA analyses carried out in 2007, it is a presumably natural cross between the Valais variety Rèze x of unknown partners. Since Rèze is also a parent of Groppello di Revò (with synonym Nosiola Nero), the synonym Groppello Bianco can be explained. There is also a genetic relationship with the variety Bonda. According to an unverifiable hypothesis it is a descendant of the Uva raetica mentioned by Pliny the Elder (23-79), from which the famous Raeticum was produced.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.Thomas Götz
