The mother places but has nothing to it Müller-Thurgau to do, which is incorrectly mentioned in some sources (apart from the fact that the Silvaner was not involved in the Müller-Thurgau). They are genes from Vitis labrusca. Vitis lincecumii. Vitis rupestris and Vitis vinifera contain. The crossing of the hybrid was done by Dr. Heinrich Birk (1898-1973) at the research institute in 1962 Geisenheim in the Rheingau. The name was given to the German-born wine pioneer Hans Breidecker, who successfully launched the variety in New Zealand. The vine is resistant to both mildews and Botrytis, It produces white wines with distinctive aromas of pears and apples. The variety is in New Zealand cultivated on seven hectares of vineyards. In Austria (Burgenland) the variety has been used for the local specialty since 2016 Uhudler used.
