Pinot blanc
Manzoni bianco or "Incrocio Manzoni 6.0.13", is a white variety which is a cross between the Riesling and Pinot blanc grapes that was created through a series of trials between 1930 and 1935. In 2005, it was suggested that Chardonnay, instead of Pinot blanc, was the second parent of Manzoni bianco, but DNA analysis has shown that Professor Manzoni's original cross is, indeed, Manzoni bianco's parentage. The grape is also known under the further synonyms of "I.M. 6.0.13", "Incrocio Manzoni 6.0.13", "Manzoni 6.0.13", and "Manzoni Bijeli".
