Synonym (also Ostesa) for the grape variety Garganega; see there.
The white grape variety comes from Italy. Synonyms are Bianchetto, Decanico, Dorana di Venetia, Garganega Bianca, Garganega Comune, Garganega di Gambellara, Garganega Gentile, Garganega Grossa, Garganega Piramidale, Garganega Veronese, Grecanico, Grecanico Bianco, Grecanico Dorato, Grecenicu Biancu, Lizzara, Ostesa, Ostesona, Recanicu(Italy); Garganega Bijela(Croatia); Malvasía de Manresa(Spain). Although it appears to have synonyms or morphological similarities, it should not be confused with Dorona di Venezia, Ribolla Gialla or Vitovska. This very old vine was already mentioned in the 13th century by Petrus de Crescentiis (1230-1320). As with some other Italian grape varieties such as Greco, among others, it is thought to be of Greek origin, which would be confirmed by its occurrence in Sicily. To date, however, no genetic relationships to Greek varieties have been found.
