Montonico bianco is a white Italian wine grape variety that is grown in the Calabria region of southern Italy. Ampelographers believe that the grape is likely of Greek origins and was transported to southern Italy by ancient Greek settlers. Though the variety has a long history in Calabria, its numbers have been slowly declining with 1100 hectares/2700 acres planted in the region by the end of the 20th century.
Recent DNA profiling has shown Garganega to be one of the parent varieties of Montonico bianco.
It is not yet clear if the grape is related to red Calabrian wine grape Gaglioppo that is also known as Mantonico/Montonico nero.
Montonico bianco is a permitted grape variety in several Denominazione di origine controllata wines including the Bivongi DOC located on the slopes of Mount Consolino. Here Montonico makes up to 30-50% of the blend along with Greco bianco and Guardavalle with Ansonica and Malvasia bianca permitted to make up an additional 30-50% and other non-aromatic white grape varieties permitted up to 30%. Montonico grapes destined for DOC wine production must be harvested to a yield no greater than 12 tonnes/hectare with the finished wine needing to attain a minimum alcohol level of at least 10.5%.
