List of grape varieties |
Roesler is a red wine variety . The name is reminiscent of Leonhard Roesler (1839–1910), who was director of the chemical-physiological experimental station for viticulture and fruit growing in the Klosterneuburg School of Viticulture from 1874 to 1902 .
Breeding, variety characteristics, approval
Like the Rathay , it is an interspecific new breed from 1960 by Gertrude Mayer at the Viticulture School in Klosterneuburg . The Roesler is a new breed from Zweigelt and ( Seyve Villard 18-402 x Blaufränkisch ).
The variety is frost hardy down to −25 ° C and very insensitive to all fungal diseases, especially to both types of powdery mildew ( powdery mildew and downy mildew of the grapevine ). Therefore, this grape is recommended in near-natural cultivation. It is one of the so-called PIWI varieties (= fungus-resistant grape varieties). The medium-early ripening grape does not make any special demands on the soil and is well tolerated by lime.
In Austria, the variety was approved as a quality grape variety in 2000. In 2004 the Roesler got the EU plant variety protection . 161 hectares of the Austrian wine-growing area (0.4 percent) are planted with Roesler (as of 2013).
Properties of the wine
The Roesler is a red wine with clear aromas of wild berries. The deeply colored berries produce deep dark wines, they are rich in extract and full-bodied and have a high tannin content . Because of its extreme color density, which is achieved even with poor vintages, the variety is also suitable as a blending partner for paler wines.
