The white grape variety is a new breeding between Riesling x Madeleine Royale. Some synonyms point to the parentage Riesling x Sylvaner, which was wrongly assumed for a long time. Within the European Union, those names that refer to it, such as Riesling-Sylvaner, are no longer permitted. The most important are Müller, Müller-Thurgau Rebe, Müller Thurgau Weiß, Weißer Müller-Thurgau (Germany); Müller-Thurgau Blanc (France); Uva di Lauria (Italy); Riesling-Silvaner, Riesling x Silvaner, Riesling-Sylvaner (New Zealand, Switzerland); Rivaner (Austria, Luxembourg), Rizlingszilvani (Hungary), Rizvanac, Müller-Thurgau Bijeli, Rizvanac Bijeli (Croatia); Rizanec, Rizvanec (Slovenia); Muller Thurgau White (USA).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.Andreas Essl
