St. Georgen is an old white wine variety from Austria, which was found again in 2000. The original name of the variety is not known. Allocation to a known variety has not yet been possible even with genetic engineering studies.

Origin, history

Austria, St. Georgen im Burgenland, St. Georgener Hetscherlberg, Ried Viehtrift.

In 2000, local researcher Michael Leberl was able to find an ancient vine in the former Viehtrift vineyard in the Burgenland town of St. Georgen near Eisenstadt am Hetscherlberg . The Viehtrift vineyard in St. Georgen am Leithagebirge has demonstrably not been listed as a vineyard in the cadastre since 1580. Earlier records fell victim to a fire in the Eisenstadt archive. From several old vines (tradition in St. Georgen) this vine has survived all weather extremes and the phylloxera disaster. Rediscovered by Michael Leberl after a long search, Hans Moser took care of their rescue, reproduction and the establishment of the experimental vineyard. His father Johann Moser senior took care of this vine. operated.

In February 2011 the vine on the St. Georgener Hetscherlberg was badly damaged in an act of vandalism. In the same year the vine was declared a natural monument.

At the suggestion of Ferdinand Regner , the variety was named after the location "St. Georgen "named. At least as an interim solution until the true name of the variety is found.

Starting from this vine, an experimental vineyard was created in St. Georgen and at the Langenzersdorfer experimental estate Götzhof of the Höhere Bundeslehranstalt and Bundesamt für Wein- und Obstbau Klosterneuburg. The first wines were presented on February 20, 2014 at Versuchsgut Götzhof. On September 29, 2015, 481 kg of grapes were harvested in the St. Georgen experimental vineyard, from which 300 liters of wine were made.

meaning

The genetic tests carried out by Ferdinand Regner from the Higher Education Institute and Federal Office for Viticulture and Fruit Growing in Klosterneuburg revealed that it was a unique vine. In comparison with the variety Grüner Veltliner, there was not 100% agreement in all gene locations, but it was unequivocally recognized on 19 chromosomes . Based on this result, the Grüner Veltliner variety is a natural cross between Traminer × St. Georgen. It is the mother variety of Grüner Veltliner . The variety does not have a decisive influence on the quality of Grüner Veltliner, which has so far been seen after several harvests with vinification . This comes from the second crossing partner, the Traminer variety.
