The red grape variety is a new variety between Blauer Portugieser x Spätburgunder (Pinot Noir), which was confirmed according to DNA analyses carried out in 2021. Synonyms are Geilweilerhof 4-25-7 and Rotspechter. The cross was made in 1927 by grower Peter Morio (1887-1960) at the Geilweilerhof Vine Breeding Institute in Siebeldingen-Pfalz. It was further developed and selected here by Dr Bernhard Husfeld (1900-1970) in the 1950s. Plant variety protection was granted in 1974. The variety was a crossing partner in the new Calandro variety.
