The white grape variety is a new breeding between Pinot Noir x Pirovano 1 (Chasselas Rose x Muscat d'Hamburg), which was confirmed by DNA analyses published in 2012. Synonyms are Falschblüher, Geisenheim 15-114, Schönberger and Schönburger Rose. The cross of the father variety was made by the Italian breeder Alberto Piròvano (1884-1973). The cross with Pinot Noir was made by the German vine expert Dr. Heinrich Birk (1898-1973) in 1939 at the Geisenheim Research Institute (Rheingau). The name is derived from Schönburg Castle in Oberwesel in the Mittelrhein growing region. The early to medium ripening vine has reddish berries. It is resistant to frost and both types of mildew. The variety produces a spicy, rather low-acid white wine with a discreet muscat tone, somewhat similar to a Gewürztraminer. Due to its special aromatic characteristics, it is called a bouquet variety. In Germany, it occupies 16 hectares; there are further stocks in Australia (0.1 ha), Brazil, England (9 ha), Canada (14 ha) and South Africa. In 2016, a total of 35 hectares of vines were reported (Kym Anderson statistics).
