The white grape variety comes from Germany. Synonyms are Damary Blanc, Lambert grape, Rachenputzer and white Lambert grape. According to DNA analyses carried out in 2013, it is a presumably natural cross between Heunisch(Gouais Blanc) x unknown partner. However, this is based on only 20 DNA markers (see molecular genetics). The presumably very old variety yields rather simple, very acidic white wines, which is indicated by the synonym Rachenputzer. It used to be widespread in Germany, where it was often cultivated in a mixed set with the varieties Elbling, Heunisch, Orléans and Riesling. In 2010, however, no more stocks were reported (statistics Kym Anderson).
