La Crescent is a white wine variety . It was crossed in 1988 by Peter Hemstad and Jim Luby from the grape varieties St. Pepin x ES 6-8-25. Hemstad and Luby are employees of the University of Minnesota , where Elmer Swenson previously worked. The variety has been approved for commercial cultivation since 2002. The grape variety was named after the municipality of La Crescent .
The Rebzüchter selected with the American grape variety St. Pepin made a hardy variety that they with the hybrid vine ES 6-8-25 crossed . ES 6-8-25 is a cross between the American variety Vitis riparia and the aromatic noble grape Muscat de Hambourg . During the trial phase, La Crescent had the breeding line number ES 6-8-25.
With the grape varieties Marquette , Frontenac Gris and Frontenac, La Crescent is now one of four varieties from the University of Minnesota that are used in the cold wine-growing climate of the US Northeast and Canada. La Crescent has been applied for a patent.
Plantings are known in the American states of Iowa ( viticulture in Iowa ), South Dakota ( viticulture in South Dakota ), Vermont ( viticulture in Vermont ), Montana ( viticulture in Montana ) and Minnesota ( viticulture in Minnesota ). In Canada , the variety is found near Quebec. Even in cold wine-growing climates, the variety develops high must weights of up to 25 degrees Brix , which corresponds to around 100 degrees Oechsle . The alcohol-rich wines are acid-rich and are therefore suitable for the production of residual sweet white wines .
University staff were looking for early maturing and hardy varieties suitable for the northern United States. La Crescent is hardy to at least -30 degrees Fahrenheit (-35 degrees Celsius). Since the roots are less hardy, the variety should be protected by a sufficiently high layer of snow on the ground.
