The white grape variety is an interspecific new breeding between SV 12-375 (Villard Blanc) x Pinot Blanc. The name means "twilight". It contains genes from Vitis berlandieri, Vitis rupestris and Vitis vinifera. The hybrid was crossed in Poland by the breeder Roman Myśliwiec. The early-maturing vine is resistant to both powdery mildew and botrytis and frost-resistant to minus 25 °Celsius. Due to its broad fungal tolerance, it is considered a PIWI variety. It produces a white wine with a muscat tone. The phylloxera-resistant variety is cultivated in Poland ungrafted. However, no stocks were reported in 2016 (Kym Anderson statistics).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
