Mantonico bianco is a white Italian wine grape variety grown in the Calabria wine region of southern Italy. The grape should not be confused with the similarly named Calabrian grape Montonico bianco or with Guardavalle, which is known as Mantonico in the province of Cosenza in Calabria. In the early 21st century, DNA profiling suggested that Mantonico bianco may be one of the parent varieties of the red Calabrian grape Gaglioppo which is also known as Mantonico nero.[1]
Today Mantonico bianco is used to make both dry varietal and sweet passito-style dessert wines under several Calabrian Indicazione geografica tipica (IGT) designations. The grape is also potentially one of the permitted varieties in the Denominazione di origine controllata (DOC) wines of Bivongi and Donnici, however, the regulations for those DOCs do not differentiate between Mantonico bianco and Montonico bianco with the later most often being used in those wines.[1]
