Leaves and grapes of the Osteiner grape variety

Osteiner is a white wine variety . It is a cross between Riesling and Silvaner , which Heinrich Birk carried out at the Geisenheim research institute in the Rheingau in 1928. The information provided by the breeder about the parents of the cross has been confirmed by DNA analysis in the meantime.

It was only granted plant variety protection in 1984 and was entered in the list of varieties in the same year .

The vigorously growing vine hardly develops any stinging shoots , which makes it less susceptible to powdery mildew and fungi. It makes no special demands on the soil, is hardy even in severe frost, flower-proof and therefore high-yielding. It produces strong, full-bodied wines with a Riesling taste, but stronger acidity (→ acidity (wine) ).

Osteiner is a variety of the noble grapevine ( Vitis vinifera ). It has hermaphroditic flowers and is therefore self-fruiting. In viticulture , the economic disadvantage of not having to grow male plants that produce yield is avoided.

The cultivation area in Germany is limited to about four to five hectares in the Rheingau , in Franconia and on the Hessische Bergstrasse . It is also approved in the Ahr , Middle Rhine , Moselle , Nahe , Palatinate , Rheinhessen and Saxony wine-growing regions . The importance of the vine can be classified as low overall. Small stocks are also known in New Zealand.

Naming

The Counts of Ostein , who resided in the Rheingau until the beginning of the 19th century , were the inspiration for the naming . The last of this tribe, Count Johann Friedrich Karl Maximilian Amor Maria (1735–1809) is particularly connected to Geisenheim through the construction of the Palais Ostein and the creation of a landscape park .
