The German diploma biologist Andreas Jung (* 1961) studied biology and anthropology 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 Weinbauinstitut Freiburg on the plant food supply for predatory mites in viticulture. From 1998 to 2005 Jung was a research associate at the Federal Institute for Plant Breeding Research Institute of Vine Breeding Geilweilerhof in Siebeldingen in the department Genetic Resources Genebank Vine. His work focused on the description, identification and characterization of old varieties, Redefinition of OIV Features, Standardization of microsatellite analysis (see molecular Genetics ) in the genetic characterization of grape varieties, identification of varieties in old vineyards on the Badische Bergstraße, as well as variety evaluation. He has practical experience in grape varieties and viticulture.
In 2006, Andreas Jung founded the "Bureau of Grape Variety and Clonal Breeding Andreas Jung" and is known as Ampelograph, such as cloning breeders and maintenance breeder. The focus is on variety registration, variety identification and clone selection in old vine stocks, conservation breeding and evaluation of old grape varieties, as well as research on the history, origin and distribution of old grape varieties. On behalf of the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), grapevine resources were collected in around 1,000 locations in Germany from 2007 onwards. In the period from 2006 to 2018, a comprehensive variety identification was carried out for the cantonal recording of vine genetic resources in the German-Swiss cantons in cooperation with Markus Hardegger, working group Vitis in the SKEK (Swiss Commission for the Conservation of Cultivated Plants).
Further activities since 2007 are a search and collection project in Brandenburg and Poland with the aim of conserving climate-adapted Brandenburg-Silesian variety clones. So far, the registration and identification of about 400 Central European grape varieties in the German-speaking and Austro-Hungarian regions, including about 120 extinct varieties such as the previously lost feeder, as well as the preservation of so far 350 historical grape varieties in over 1,500 clones in own variety and clone conservation plants. Jung completed study visits in France, Ticino, South Tyrol, Piedmont, Lower Austria, Hungary, Croatia, Serbia, Crimea and Georgia. In 2011, Andreas Jung received the Oberdieck Prize of the Pomologenverein and the city of Naumburg and in 2016 the Golden Cork of the Weinloge München. The current focus of activities is the reintroduction of the old varieties into the wine market with the support of the nursery U. Martin GmbH and their website Historical grape varieties .
