“Foundlings” are colloquially known as wild and initially unknown grape varieties, the origin of which is unclear (see also under bloomed open ). The name is also used as a name for at least three different white grape varieties.
1) A variety called "Findling" is listed in the variety register of Germany. It is according to DNA analysis but not an independent variety, but rather the variety grown in Austria in large quantities Bouvier (personal information from Dr. Erika Maul dated Julius Kühn Institute ). In 2010, it occupied a total of 27 hectares of vineyards, especially in the two growing areas to bathe and Moselle,
2) Another variety known as boulder was found, selected and propagated by the breeder Franz Kimmig in Oberkirch (Baden, Germany) in 1971. It is a mutation of Müller-Thurgau; however, a DNA determination has not yet been carried out. The differences are earlier Maturity date, lower yield and higher Mostgewicht, It is used in small quantities in the Swiss canton Geneva cultivated (personal information from Dr. José Vouillamoz ); it is not known whether there are stocks in Germany.
3) The variety "Findling von Muhen" with a dark red berry color comes from the Switzerland (Muhen is a municipality in the district of Aarau in the canton Aargau with the parts underwear, middle shoes and upper shoes). However, the fantasy name is not yet valid for ampelography. It was found by a Swiss amateur ampelographer. The vine has an independent DNA profile that differs from Müller-Thurgau. The parentage is unknown (Dr. José Vouillamoz).
