The red grape variety is a new breed between Blauer Portugieser x Spätburgunder (Pinot Noir), which was confirmed according to DNA analyses carried out in 2013. Synonyms are Geilweilerhof 4-25-7 and Rotspechter. The cross was made in 1927 by the breeder Peter Morio (1887-1960) at the vine breeding institute Geilweilerhof in Siebeldingen-Pfalz. Here it was further developed and selected 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. The medium-maturing, high-yielding vine has a medium Botrytis resistance and tends to stem rot. However, it has good resistance to chlorosis, viruses, trickling and frost. The variety produces red wines similar to Pinot Noir, but somewhat more acidic and rich in extract, with aromas of bomberries and cherries. The area under cultivation in Germany is 366 hectares (D-STATIS). There are also small stocks in Switzerland (0.1 ha) and Hungary (0.6 ha). In 2016, a total of 375 hectares of vineyards were reported (Kym Anderson).
