The red grape variety (breeding no. FR 523-89 r) is a new variety between Seibel 7053 (Chancellor) x (Merzling x (Zarya Severa x Muskat-Ottonel)). This is also indicated in the form Chancellor x Solaris, because the Solaris variety later emerged from the father variety through selection. It contains genes from Vitis amurensis, Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1989 at the State Viticulture Institute in Freiburg (Baden-Württemberg). It was granted variety protection in 2003 with the status of a variety of the species Vitis vinifera. The late-maturing, frost-hardy and fungus-resistant vine (PIWI) is highly resistant to powdery and downy mildew; the tendency to stem rot and coulure is low. It produces intensely coloured red wines rich in extract and tannins. The variety is cultivated in Switzerland. In 2016, 1.5 hectares of vineyards were designated (Kym Anderson).
