Difficult to trace to its origins, as in the past it was confused for a biotype of Corvina Veronese , this red grape variety was entered in the National Catalogue of varieties of vine wine only in 1993. The Cosmos (1939) described it as a subvariety of Corvina. The name may come from its almost black color that invokes the plumage of the raven, or from " corba ", which was transported to the basket with the grapes for its abundant production. Today this variety are known two biotypes which differ in the size of the leaves and grapes, but also for different aging times, both called Corbinon or Cruinon .
