The white grape variety (also L-3-9-25) is an interspecific new variety between (Blaufränkisch x Cabernet Franc) x Merlan; the name was formed from the parent varieties. It contains genes of Vitis berlandieri, Vitis rupestris and Vitis vinifera. The hybrid was crossed in the Czech Republic by a team led by Vilém Kraus (1924-2013). The plant variety protection was granted in 2011. The late-maturing, high-yielding vine is moderately resistant to frost, and very good against botrytis and both types of mildew. It produces spicy white wines similar to Sauvignon Blanc with grass and nettle aromas that tend to oxidize. In 2016 no stocks were reported (statistics Kym Anderson).
