The white grape variety originates from the border region Italy (Gorizia)-Slovenia (Goricia). Synonyms are Uccellut, Uccelutt and Ucielute. The vine, supposedly selected from wild vines, has been cultivated in the province of Pordenone(Friuli Venezia Giulia) for several centuries. It is one of the "Uve Uccelline" (rowan berries), from which the name derives, which are highly appreciated by birds. The vine, which is almost extinct, was reactivated in the 1980s by the winemaker Emilio Bulfon with the help of the ampelographs Antonio Calò and Ruggero Forti. The late maturing vine is susceptible to botrytis, which makes it suitable for the production of noble sweet passito. It is cultivated in the two municipalities of Castelnovo di Friuli and Pinzano al Tagliamento. In 2010, ten hectares of vineyards were designated (statistics Kym Anderson).
