The vine, which ripens early to medium and is frost-hardy down to minus 31 °Celsius, is very susceptible to powdery mildew and moderately susceptible to botrytis and downy mildew. It produces fruity, rather low acidity white wines with a subtle foxtone. The variety is also used as table grape. It is grown in small quantities in the US states of Connecticut, Illinois, Iowa, Minnesota, New York, West Virginia and Wisconsin, as well as in Canada. In 2010, it covered a total of 19 hectares of vineyards in the USA (Kym Anderson statistics).
