The red grape variety originates from Italy. Synonyms are Cruaja, Cruajo, Fogarina, Friulara, Friulara di Bagnoli, Friularo, Friularo Rabiosa, Rabosa, Rabosa Friualara, Rabosa Nera, Raboso, Raboso del Piave, Raboso di Conegliano, Raboso di Piave, Raboso Friularo, Raboso Nera, Raboso Nostrale, Raboso Nostrano, Raboso Nostrano Nero and Rabozo Pijave. It should not be confused with the varieties Fogarina, Groppello Gentile, Gruaja or Raboso Veronese, despite seemingly suggestive synonyms or morphological or name similarities. According to DNA analyses carried out in 2006, the Raboso Veronese variety was created from a presumably natural cross between Raboso Piave x Marzemina Bianca. Until then, Raboso Piave and Raboso Veronese were considered to be identical or varieties. The parentage is also supported by the fact that Raboso Piave was first mentioned in 1679, while Raboso Veronese was only mentioned in the 19th century. Furthermore, analyses carried out in 2011 revealed a parent-descendant relationship between Raboso Piave and Fogarina.
