The white variety is a new variety, the crossing was made in 1928 by Peter Peter Morio (1887-1960) on Grapevine Breeding Institute Geilweilerhof Siebeldingen-Palatinate. The breeder was a parent of Silvaner x White Burgundy, but in fact it is a cross between a Silvaner x Muscat. The Plant Variety Protection was granted in 1956. The name is a reference to the breeder and the pronounced nutmeg. Until the early 1970s, the variety was very popular in Germany, but since then the stock has declined sharply. In 2009 she won there only 488 hectares of vineyards. In Austria and Switzerland, there are also only small amounts.
