'GR 7' is an early / mid-season red wine grape for use
primarily in red wine blends. It is distinguished from other red
wine grapes grown in cool climates by its high degree of winter
hardiness, adaptation to mechanized production systems, and
ability to survive in older plantings where other red wine grapes
are lost due to tomato and tobacco ringspot virus infections. ?GR
7? is a highly productive, easy to manage cultivar, and is the sixth
wine grape to be developed by the New York State Agricultural
Experiment Station of Cornell University
