The white grape variety is an interspecific cross between Taylor x Martha (but paternity is not assured). Synonyms are Rommel's N. 1 and Taylor's Seedling N. 1 and should not be confused with the Noah variety with which it shares the parent Taylor. It contains genes from Vitis labrusca, Vitis riparia and Vitis vinifera. The hybrid was selected around 1860 in Missouri by Jakob Rommel. She was crossing partner in the new breeding Ventura. The medium maturing, very productive vine is resistant to winter frost and downy mildew, but susceptible to botrytis. Due to its good resistance to phylloxera, it is often cultivated as a direct carrier (ungrafted). It yields acidic white wines with a pronounced foxtone.
In the USA there are stands in the states of New York and Pennsylvania (255 ha in total) and in Canada (8 ha). In Austria (Burgenland) it is one of the varieties for the local speciality Uhudler (no record). There are also some vines in the vine museum of Franz Leth (Fels in Lower Austria). In 2010, a total of 263 hectares of vineyard area were declared (statistics Kym Anderson).
