The white grape variety is a new cross between Riesling x Muscat St. Laurent. The cross was made by the French breeder Christian Oberlin (1831-1915) in Colmar (Alsace, France). Incidentally, the same parents also produced the varieties Bouquetriesling, Diamantmuskat, Edelmuskat, Feinriesling, Firnriesling, Marienriesling, Muscat de la Republique, Muscat Dore de Semis, Muskatblume, Muskatbouquet, Muskatduft and Muskatriesling. No stocks were recorded in 2016 (Kym Anderson statistics).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
