The white grape variety originates from Italy. Synonyms are Cacciadebiti, Caccione, Camplese, Pagadebito, Passera, Passeretta Bianca, Passerina Bianca, Scacciadebito, Tramarina, Trebbiano di Teramo, Uva d'Oro and Uva Fermana. It must not be confused with the varieties Biancame, Bombino Bianco, Mostosa, Trebbiano d'Abruzzo or Trebbiano Toscano, despite seemingly suggestive synonyms or morphological similarities. It is a very old variety, probably directly descended from wild vines. Genetically almost identical to Passerina is the Greek variety Korinthiaki Lefki. This was already established by Lambert J. von Babo (1790-1862) in 1844 and later by Pierre Galet (1921-2019). However, the two varieties differ slightly in the shape of the leaves and clusters. There is probably a Greek origin. The Italian variety may have reached Italy as early as the 6th century.
