The red grape variety comes from Italy. Synonyms are Durera, Rastagliola and Restajola. It should not be confused with the Erbaluce Nero or Neretto Duro varieties because of apparent synonyms or morphological similarities. The medium ripening vine is susceptible to small berries (millerandage) and downy mildew. It was once widespread in the north of Piedmont. Today, it is grown in the province of Novara only in small quantities and is mainly used as a blend. In 2016, however, no stocks were recorded (statistics Kym Anderson).

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
