The white grape variety is a new variety between Riesling x Malingre Précoce(Précoce de Malingre) according to DNA analysis carried out in 2016 (the father variety has not yet been confirmed). The sire variety Courtiller Musqué Précoce(Muscat Précoce de Saumur) in the breeding list turned out to be wrong in any case and was crossed by Christian Oberlin (1831-1915) in Colmar(Alsace, France). In the year 2016 no stock was shown (Kym Anderson).
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.
