The white grape variety is an interspecific new variety between Elmer Swenson 114 (Minnesota 78 x Rosette) x Seyval Blanc. Synonyms are Elmer Swenson 294, ES 294 and Lacrosse. The name was given after the town of the same name in western Wisconsin. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis riparia, Vitis rupestris and Vitis vinifera. Incidentally, the same parents also produced the new variety St. Pepin. The hybrid was crossed in 1971 by the breeder Elmer Swenson (1913-2004) near Osceola (Wisconsin). Plant variety protection was granted in 1983. The early-ripening vine, which is frost-hardy down to minus 29 °Celsius, is particularly susceptible to black rot and botrytis, as well as to both types of powdery mildew. It produces fruity white wines with aromas of pears, apricots and citrus fruits, which are mainly used for blending. It is also used as table grape and for the production of grape juice. The variety is grown in the Midwest of the USA in the states of Illinois, Iowa, Minnesota, Nebraska, Nevada, Ohio, Pennsylvania, South Dakota and Wisconsin. In 2016, a total of 26 hectares of vineyards were designated (Kym Anderson).
