The white grape variety most likely originates from Italy. Synonyms are Malvasia Casalini, Muscadelle du Bordelais, Muscadelle du Bordelais Faux and Muscadelle of California. It is one of the many varieties with the name part Malvasia. It should not be confused with the French variety Muscadelle (with synonym Muscadelle de Bordelais). According to DNA analyses carried out in 2020, it is probably a natural cross between Muscat Blanc x (Nebbiolo x Bottagera). Whether there is a relationship to the Italian variety Malvasia Odorosissima (with the synonym Malvasia Aromatica di Parma) is not known. It is an all-female grape variety. The variety was a crossing partner of the new variety Emerald Riesling as well as a parent of the varieties Bonardina, Brachetto Migliardi, Malvasia Bianca di Piemonte, Malvasia Bianca di Vignale, Malvasia di Candia Aromatica, which probably originated from natural crossings. Malvasia di Casorzo, Malvasia Nera Lunga, Poliziana and Ruchè. No stocks were reported in 2016 (Kym Anderson).
