Uhudler is a unique wine from Austria, which originates in the Südburgenland region (see Burgenland). In appearance it is often a rosé colour, but is also made as a white wine. It has intense flavours of strawberry and black currants, a characteristic taste often called "foxy" in wine parlance. The grape varieties used are highly resistant to phylloxera and other diseases; as a result they do not often have to be sprayed with pesticides. They also require little fertilization because of their vigorous growth.
The grapes/clusters are usually red, but also (less commonly) white. The varieties used are inter-specific hybrids, which were developed from crossings between the European species Vitis vinifera with the native North American Vitis labrusca and Vitis riparia. It is Vitis Labrusca which lends the wine its characteristic "strawberry" flavouring. "Uhudler" can refer to several varieties and today it is disputed which varieties rank in the "Uhudlergruppe" (Uhudler group) and which do not. Some of the varieties used include the grapes Concord, Isabella, Elvira, Clinton, Ripatella and Noah.
Uhudler originates from the time of the large phylloxera infestations around 1860. The phylloxera aphid reached Europe in 1860 and Austria in around 1900. After the losses of the European grape varieties through phylloxera, many attempts were made to either exterminate the pest or use alternative, non-traditional viticultural practices which would prevail against infestation.
In time, disease resistant North American vines (including some used in Uhudler wines) were imported to Europe and used to produce wine. Many crossings between native North American and European varietals were created at this time. The wine produced did not correspond in any way to the established taste trends in Europe. During the early 20th century, however, some fruit from North American vines were blended with that from Vitis vinifera to enhance the "fruitiness" of the wine.
