The white grape variety (also Geisenheim 18-92, Rajhenstajner) is a new breed between Müller-Thurgau x (Madeleine Angevine x Weißer Calabreser = Calabrisi Bianco), which was confirmed by DNA analyses published in 2012. The name is derived from the castle Reichenstein near Trechtingshausen in the Rheingau. The crossing of the father variety was done in 1939 by Dr. Heinrich Birk (1898-1973), the second crossing with Müller-Thurgau was done by Dr. Helmut Becker (1927-1990) in Geisenheim (Rheingau). Plant variety protection was granted in 1978. The variety was a crossing partner of the new varieties Bolero, Ehrenbreitsteiner, Gamaret, Garanoir and Mara. The early to medium ripening vine is resistant to downy mildew and botrytis. It produces a flowery white wine with moderate acidity. Stocks exist in Germany (43 ha), England (42 ha), Ireland, Japan, Canada (5 ha), New Zealand (14 ha) and Switzerland (0.3 ha). In 2016, a total of 120 hectares of vines were reported with a decreasing trend (Kym Anderson).
