Magliocco Dolce (also known as Marsigliana nera) is a red Italian wine grape variety that is grown mostly in the Calabria region of southern Italy.
DNA evidence in the early 21st century cast doubt on the validity of that theory, making it seem more likely that both grapes originated in southern Italy.
The early synonym Arvino suggest that potentially Magliocco Dolce originated near Lago Arvo on the La Sila plateau that straddles the borders of the provinces of Catanzaro, Cosenza and Crotone in Calabria.
[1] Magliocco Dolce is a late ripening grape variety that tends to produce wines with high tannin levels due to the thick skins of its berries.
In fact, the vineyard samples of Nocera planted at the University of California-Davis were identified in the early 21st century as actually being Magliocco Dolce.
