The white grape variety is an interspecific new variety between Merzling x (Villard Blanc x Pinot Gris). It contains genes from Vitis berlandieri, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in the Czech Republic by a team led by Vilém Kraus (1924-2013). Plant variety protection was granted in 2008.

The late-maturing vine is resistant to botrytis and powdery mildew, as well as moderately resistant to downy mildew. It produces yellow-green, aromatic white wines with a vegetal flavour.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
