The white grape variety originates from the border region Italy/Slovenia. Synonyms are Avola, Erbula, Gargania, Rabola, Rabiola, Rebolla, Ribolla Bianca, Ribolla Gialla di Rosazzo, Ribolla di Rosazzo and Ribuèle(Italy); Jarbola, Jerbula, Ribola Bijela(Croatia); Garganija, Garganja, Grganc, Rebula, Rebula Bela, Zelena Rebula(Slovenia). According to DNA analyses, a parent-offspring relationship with the variety Gouais Blanc seems possible. In spite of apparently indicative synonyms or morphological similarities, it should not be confused with the varieties Garganega, Pignoletto (Ribolla Riminese), Prosecco Lungo (Ribolla Spizade) or Robola. There is no relationship with the red variety Schioppettino (Ribolla Nera).
