The red grape variety is an interspecific new breeding between Fratava x Merlan. The original name was for a long time Kaberon; synonyms are Na and L-3-10-34. It contains genes from Vitis aestivalis, Vitis berlandieri, Vitis labrusca, Vitis rupestris, and Vitis vinifera. The crossing of the hybrids took place in Czech Republic by a team led by Vilém Kraus (1924-2013). The varietal protection was granted in 2010. With the same parents, the new breeds Cerason, Kofranka, Laurot, and Marlen have also been created. The late ripening grape is resistant to Botrytis and both mildew types. It produces ruby-colored, tannic and acidic red wines with aromas of spices and sour cherries. The variety is grown in Moravia; in 2016, no stock was reported (Kym Anderson).
