The white grape variety (also Geisenheim 9-97) is a new variety between Riesling x Silvaner, which has been confirmed by several DNA analyses, most recently in 2018. Count Friedrich Karl Maximilian von Ostein (1735-1809), who had the Ostein'sche Palais and a landscape park built in Geisenheim, was honoured with the name. By the way, the three new breeds Multaner, Oraniensteiner and Rieslaner were created with the same parents. The crossing was made by Dr. Heinrich Birk (1898-1973) in 1929 at the Geisenheim Research Institute in the Rheingau. Plant variety protection was only granted in 1984. The medium to late-maturing, high-yielding vine is resistant to frost, both types of mildew and botrytis. It produces fresh, acidic white wines with aromas of currants and lemons. In 2016, only a small stand of one hectare was designated in New Zealand (statistics Kym Anderson).
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
