There are two grape varieties with this name:
The red grape variety (also FR 487-88 R) is a new breeding between (Merzling x (Zarya Severa x Muskat-Ottonel)) x Dornfelder. In some sources this is stated in the form Solaris x Dornfelder; because the Solaris variety later emerged from the mother variety through selection. Genes of Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera are included. The hybrid was crossed in 1988 by Norbert Becker (1937-2012) at the Viticulture Institute in Freiburg. The late-maturing, frost-hardy vine is resistant to both types of mildew. It produces colour-intensive, tannin-rich red wines. There are stocks in Germany (11 ha), in Italy and in Switzerland (2 ha). In 2018, 13 hectares of vines were reported (D-STATIS).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.Andreas Essl
