Life Style / Wine Grapes / Kay Gray: Elmer Swenson patented American labruscana, released in early 1980's, suitable for table, juice or white wine use. Claimed to be hardy to -40 deg. F. (ca -42 C.). Very vigorous, heavy bearer. Disease resistant, with some susceptibility to Black Rot. Ripens early in season with small clusters making it a poor tablegrape choice. Some use it to make a labrusca-style white wine that has the reputation of easy oxidation, so it is not high on commercial growers recommendation list. Currently grown on limited acreages in South Dakota. (No other details available as yet).
