The white grape variety is a new variety between Saperavi Severny x (Foster's White Seedling x Prachttraube). Synonyms and breeding numbers are Geisenheim 6495-4 and GM 6495-4) It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1964 by Vilém Kraus (1924-2103) in Lednice in the former Czechoslovakia. The seedlings were then selected in Geisenheim (Rheingau) under Dr Helmut Becker (1927-1990). Incidentally, the same parents also produced the new Sibera variety. The early-ripening vine is resistant to both types of mildew and frost and is less susceptible to botrytis due to its loose berries. It produces full-bodied white wines. No stock was recorded in 2016 (Kym Anderson).
