The white grape variety (also BV 19-88) 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 2001 in the Czech Republic by a team led by the breeder Vilém Kraus (1924-2013). Plant variety protection was granted in 2010. Incidentally, the same parents also produced Malverina and Vesna. The late-maturing vine is resistant to frost, botrytis and both types of powdery mildew. It yields lemon-yellow, acid-accentuated white wines with aromas of honey and vanilla as well as storage potential. No stock was recorded in 2016 (Kym Anderson).
