Like many Muscat varieties, Moscato Giallo was long thought to be of Middle-Eastern origin, with
Syria being the birthplace most commonly cited. However, in the early 21st century
DNA analysis showed that Moscato Giallo shared a parent-offspring relationship with
Muscat blanc à Petits Grains (also known as Moscato bianco). As the first documented mention of Muscat blanc à Petits Grains (under the synonym of
Muscatellus) could be dated to the early 14th century, it is likely that the seemingly more recent Moscato Giallo is the offspring in the relationship. Through this relationship with Muscat blanc à Petits Grains, Moscato is a half-sibling to several other grape varieties including
Aleatico,
Moscato di Scanzo,
Moscato Rosa del Trentino,
Muscat of Alexandria and
Muscat rouge de Madère. As the vast majority of plantings of Moscato Giallo and its proliferation of siblings are found in northern Italy,
ampelographers believe that the grape more likely originated in Italy than in the
Middle East. Similarities in name and
morphology often lead to Moscato Giallo being confused with other Muscat varieties such as with the Moscato bianco in
Sicily. ==Viticulture==
