The red grape variety originates from Italy (South Tyrol). Synonyms are Calebstraube, Roter Urben, Rotwelscher, Süßwälscher, Urbanitraube and Urban Crveni. It is a member of the heterogeneous name group Schiava. Due to similar synonyms or morphological similarities, the variety must not be confused with the genetically related variety Roter Trollinger (mutation of Schiava Grossa). It is a colour mutation of the variety Schiava Gentile (Blue Urban). It is used as a winepress and table grape. However, no stocks were reported in 2016 (Kym Anderson statistics).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
