Breidecker

The white grape variety (also Geisenheim 4984) is an interspecific new breeding between (Riesling x Silvaner) x Seibel 7053 (Chancellor). The mother variety has nothing to do with Müller-Thurgau, which is incorrectly mentioned in some sources (apart from the fact that in Müller-Thurgau, Silvaner was not involved). It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris, and Vitis vinifera. The name honors the German-born wine pioneer Hans Breidecker, who successfully introduced the variety in New Zealand.

Breidecker - grape and leaf

The crossing of the hybrids was carried out by the breeder Dr. Heinrich Birk (1898-1973) in 1962 at the Geisenheim Research Institute in the Rheingau in Germany. The vine is resistant to both mildew types and Botrytis. It produces white wines with pronounced aromas of pears and apples. The variety is cultivated in New Zealand on 0.5 hectares. In Austria (Burgenland), the variety has been approved since 2016 for the local specialty Uhudler, but no stocks were reported in that year (Statistics Kym Anderson).
