The German graduate biologist Andreas Jung (*1961) studied biology and ethnology at the Albert Ludwigs University in Freiburg (Baden-Württemberg) with a focus on plant systematics, geobotany, plant physiology, limnology and ethnoecology. He completed his diploma thesis at the Institute of Viticulture in Freiburg on the plant food supply for predatory mites in viticulture. From 1998 to 2005, Jung was a research assistant at the Federal Institute for Breeding Research Institute for Grapevine Breeding Geilweilerhof in Siebeldingen in the Department of Genetic Resources - Genetic Resources - Grapevine. His work focused on the description, identification and characterisation of old grape varieties, redefinition of OIV characteristics, standardisation of microsatellite analysis (see molecular genetics) in the genetic characterisation of grape varieties, variety identification in old vineyards along the Badische Bergstrasse, and variety evaluation. He has practical experience in the field of grape varieties and viticulture.
In 2006 Andreas Jung founded the "Büro für Rebsortenkunde und Klonzüchtung Andreas Jung" and is active as an ampelographer as well as clone breeder and conservation breeder. The focus is on variety registration, variety identification and clone selection in old vine stocks, conservation breeding and evaluation of old vine varieties, as well as research on history, origin and distribution of old vine varieties. On behalf of the BMELV (Federal Ministry of Food, Agriculture and Consumer Protection), the recording of grape genetic resources in Germany at around 1,000 sites has been carried out since 2007. Between 2006 and 2018, a comprehensive identification of varieties was carried out in the cantonal recording of vine genetic resources in the German-speaking cantons in cooperation with Markus Hardegger, Vitis working group in the SKEK (Swiss Commission for the Conservation of Cultivated Plants).
Further activities since 2007 include a search and collection project in Brandenburg and Poland with the aim of preserving climate-adapted Brandenburg-Silesian variety clones. So far, the registration and identification of about 400 Central European grapevine varieties in the German-speaking and Austro-Hungarian regions, including about 120 extinct varieties such as the hitherto lost feeder, has been carried out, as well as the preservation of 350 historical grapevine varieties in over 1,500 clones in our own variety and clone preservation facilities. Jung completed study visits to France, Ticino, South Tyrol, Piedmont, Lower Austria, Hungary, Croatia, Serbia, Crimea and Georgia. In 2011 Andreas Jung received the Oberdieck Prize of the Pomologists' Association and the City of Naumburg and in 2016 the Golden Cork of the Munich Wine Lodge. The current focus of his activities is the reintroduction of the old varieties into the wine market with the support of the Rebschule U. Martin GmbH and its website Historical Grape Varieties.
