The white grape variety (also Geilweilerhof SBL. 2-19-58) is an interspecific new breed between Oberlin 716 (Gamay x Riparia Millardet) x Riesling 91, They are genes from Vitis riparia and Vitis vinifera contain. The crossing of the hybrid was carried out in the 1930s by Dr. Bernhard Husfeld (1900-1970) in the grape breeding department of the Kaiser Wilhelm Institute in Müncheberg Mark Brandenburg, The selection was made in 1940. The naming was based on National Socialist ideas. Given the bad experiences with French hybrids in the previous decades, the variety was the one that emerged around the same time Siegfriedrebe a phenomenal success from a breeding and scientific point of view.
Because of their great resistance to both types of mildew and Botrytis, as well as against winter frost, it was used to produce wines in Germany until the 1980s. Disadvantages were strong fluctuations in earnings due to the strong tendency to Verrieseln and virus susceptibility, Apart from that, it could no longer be used anyway because of the EU hybrid ban for the production of quality wines. As a crossing partner for fungus-resistant ( PIWI ) new varieties was the variety on Geilweilerhof (Pfalz), however, used. Aris is also a synonym for the Spanish grape variety alarije; look there.
