Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

I claim: 1. A new and distinct variety of grapevine, substantially as shown and described herein, characterized particularly as to novelty by the unique combination of winter hardiness down to -32° Fahrenheit in central Wisconsin and Minnesota, with grapes of relatively low acidity, high sugar content, a desirable aroma and flavor with an absence of foxiness or labrusca and producing a good quality white wine, as well as being highly desirable in view of its blending qualities.
