The red grape variety comes from Italy. Synonyms are Rossara Gentile, Ross Ciàr, Rossera and Varenzasca. The name refers to the possible place of origin Trentino, as well as the reddish berries. It must not be confused with the Rossara or Rossola Nera varieties, despite the fact that the synonyms or morphological similarities seem to indicate this. There is also no connection to any of the many Schiava varieties (Vernatsch). According to DNA analyses carried out in 2013, Rossara Trentina is one of the many descendants of Gouais Blanc (White Heunisch); the second parent is unknown. According to DNA analyses, the Schiava Lombarda grape variety, which is listed in the Italian grape variety lists as an independent grape variety, is identical (personal information of Dr. Erika Maul of JKI). However, this is based on only 15 DNA markers (see molecular genetics). A genetic relationship exists to the variety Sgavetta. This late-maturing, high-yielding vine is resistant to downy mildew, but susceptible to fungal diseases such as powdery mildew, botrytis and flavescence dorée. It produces fresh, perfumed red wines with apple-like acidity. The variety is mainly grown in the Rotaliano plain in Trentino, where it is often blended with the Negrara Trentina and Teroldego varieties. In Piedmont it is cultivated under the name Varenzasca. In 2016, 6 hectares of vineyards were designated (Kym Anderson).
