 Vines of this variety were distributed in Switzerland and abroad from 1908, and in 1913, 100 vines of this variety were taken to Germany by August Dern (1858−1930), who had worked with Müller in Geisenheim.Dern introduced the name "Müller-Thurgau" for the variety, while Müller himself continued to call it Riesling x Silvaner 1, although he did express doubts that this was the actual parentage of the new variety, and speculated that some misidentification of vine material could have occurred in the move from Geisenheim to Wädenswil.Many experimental plantations of Müller-Thurgau in Germany were conducted from 1920, and its breakthrough from 1938 is credited to the grape breeder Georg Scheu in Alzey.
