The white grape variety (also Incrocio Rigotti 84-11) is a new variety between Garganega x Traminer. Through a DNA analysis carried out in 2000, the Trebbiano Toscano, which is indicated in the breeding list as the mother variety, was found to be incorrect. However, this is based on only 8 DNA markers (see molecular genetics). The cross was made in 1947 by the botanist Rebo Rigotti at the Viticulture Institute San Michele all'Adige (Trentino-AltoAdige region). The medium ripening vine is resistant to frost, both mildew and botrytis. It is excellent for Spätlese. The variety is cultivated in small quantities in the regions of Puglia and Tuscany. In 2010, nine hectares of vineyards were designated (Kym Anderson).
