The first mention of a "Magliocca" grape dates to the late 15th century when it was documented growing in the Calabria region. However, which "Magliocco" grape this was is not yet known. Ampelographers have speculated that since the name Magliocco means "tender knot" in Greek that potentially Magliocco Dolce could have originated in Greece. Additionally, Magliocco Dolce has been known under the synonym of Greco nero around the village of Lamezia Terme. However, DNA evidence in the early 21st century has cast doubt on the validity of that theory with it being far 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.
Viticulture and confusion with other grapes
Magliocco Dolce is a late ripeninggrape variety that tends to produce wines with high tannin levels due to the thick skins of its berries. Like Sangiovese and Savagnin, the grape variety is very prone to mutation with several clonal varieties of the grape found throughout Calabria. Over the years, Magliocco Dolce has been confused with several other red Italian grape varieties including Gaglioppo, Magliocco Canino, Castiglione, Nerello Mascalese and Nocera. 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.
Wine regions
Today Magliocco Dolce is found almost exclusively in Calabria though the exact number of plantings of the grape variety is hard to determine because for many years the grape was often confused and inter-planted in field blends with other varieties. Even in the official 2000 census, plantings of Magliocco Canino and Magliocco Dolce were counted together though ampelographers believe that most of the Calabrian plantings in the provinces of Catanzaro, Cosenza and Crotone of the reported are Magliocco Dolce.
