The white grape variety is a new variety between Schiava Grossa (Trollinger) x Riesling, which was last confirmed by DNA analyses carried out in 2018. Synonyms are Herold Triumpf, Kerner Bijeli, Kernerrebe, Trollinger x Riesling Renano S 25/30, Weinsberg S 25 and (first name) Weißer Herold. The cross was made in 1929 at the State Teaching and Research Centre in Weinsberg (Württemberg) by the breeder August Herold (1902-1973). Plant variety protection was granted in 1969. The name was given after the Swabian doctor and wine writer Justinus Kerner (1786-1862), who lived in Weinsberg. Incidentally, Rotberger and Witberger also originated from the same parents. Kerner was a crossing partner of the new varieties Juwel, Roter Milan and Silcher. One mutation is Kernling, which is characterised by fewer stingy shoots.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
