Edelweiss is a very winter-hardy wine grape variety derived from crossing the Minnesota 78 and Ontario grapes. It was developed by Elmer Swenson in 1980 in cooperation with the University of Minnesota. The clusters are large and rather loose weighing a pound or more. Early picking of the grape is essential for making a wine. Should Edelweiss not be harvested early the completely ripe Vitis labrusca flavoring becomes too strong for the palate of most.
