Marzemina bianca
Marzemina bianca is a white Italian wine grape variety that is grown in the Veneto region of northeastern Italy. Ampelographers believe that the grape is a natural crossing of the Trentino wine grape Marzemino and the Soave wine grape Garganega. This parent-offspring relationship between Marzemina bianca and Marzemino makes the variety distinct from grapes like Pinot blanc and Grenache blanc which are other color mutations of Pinot noir and Grenache, respectively. DNA analysis has confirmed that the Veneto grape Raboso Veronese is the offspring of Marzemina bianca and Raboso Piave.
