Abstract
A grapevine cultivar having a combination of good winter hardiness, vigor, grape cluster size, disease resistance and overall suitability as a red wine grape; the vine is winter hardy to about −40 degrees F. (about −40 degrees C.) and the grape is well-suited to the commercial production of Ice Wine because its grape clusters have a tendency to resist splitting and falling off the cluster after a hard freeze; the grapevine also produces relatively large clusters of grapes that are beneficial to commercial production.
