The red grape variety is an interspecific new breeding between the white variety Rakisch x the red variety Merlan. It contains genes from Vitis aestivalis, Vitis berlandieri, Vitis labrusca, Vitis rupestris and Vitis vinifera. The hybrid was crossed in the Czech Republic by a team led by the breeder Vilém Kraus (1924-2013). Incidentally, the same parents also gave rise to the varieties Malverina and Savilon. In 2016, no stock was reported (Kym Anderson).
As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.
