This white grape variety comes from Austria. It belongs to the large Veltliner group. Synonyms grouped by country are Valtelin Rouge Blanc (France); Blasser Veltliner, Rothweißer Veltliner, Rotweißer, Silberweißer, Silberweißer Veltliner (sometimes also considered an independent variety), Todträger, Wachtler (Austria); Červeno Biely Muskatel, Muskatel Červenobily, Veltlínske Červenobiele (Slovenia); Rybola Tchervena, Veltlínské Červenobílé(Czech Republic). It is a colour mutation of Roter Veltliner. The variety was used in the new varieties Devín and Hetera. The name derives from the fact that the berries turn red on the side facing the sun, but very often remain green in the shade. In the 1920s it was one of the main varieties in Lower Austria. It is still cultivated there in small quantities. In 2016, however, no stocks were reported (Kym Anderson statistics).
