The white grape variety is a new breed between Sylvaner x muscatel ( Muscat Blanc ). Synonyms are Geilweilerhof I-28-30, Morio Muscat and Morio Muskotaly. The crossing took place in 1928 by Peter Morio (1887-1960) at the Vine Breeding Institute Geilweilerhof in Siebeldingen-Pfalz. The variety protection was granted in 1956. By done in 2012 DNA analysis the white burgundy (Pinot Blanc) indicated as the father variety in the breeding list had turned out to be wrong. There have always been doubts about parenthood because the muscatel aroma could not be explained. There is a special story about the enlightenment, because Morio's employee had been on his deathbed, so to speak, that he had deliberately not dusted the Silvaner with pollen from Pinot Blanc, but from the Muscat.
The medium to late ripening, productive vine is very susceptible to Botrytis and real ones mildew, as well as moderate for downy mildew. It produces acidic white wines nutmeg, as well as lemon and elderflower aromas. The variety was in until the early 1970s Germany very popular, but since then the stock has declined sharply. In 2009 she only occupied 488 hectares of vines (compared to 1,481 in 1999), especially in the two growing areas Rheinhessen and palatinate, In Austria it does not appear in the list of grape varieties. There are further stocks in South Africa (39 ha) and supposedly in Japan, In 2010 a total of 527 hectares of vineyards were reported (Statistics Kym Anderson ).
