The red grape variety comes from Germany. Synonyms are Blauer Gelbhölzer, Blauer Hudler, Blauer Kläpfer, Blauer Luttenberger, Blauer Räuschling, Gelbhölzer, Kläpfer, Räuschling Noir, Schwarze Lomersheimer and Schwarzer Räuschling. It must not be confused with the Red Rustling variety. According to DNA analyses carried out in 2013, it is a presumably natural cross between White Heunisch(Gouais Blanc) x unknown partner. No stocks were reported in 2010 (Kym Anderson).
