Kay Gray is a very hardy medium sized and delicious green grape. The flavour varies from a rather ordinary labrusca to a pleasant fruity flavour, depending where it is grown. It’s a vigorous grower producing many small clusters and ripen around early September. It has been proved to be hardy to -42 Celsius. Kay Gray has very good resistance to disease and is preferred by organic grape growers. Bred by Elmer Swenson in Osceola, Wisconsin. Found almost by accident: one year Mr. Swenson was ill and didn't spray his vineyard. There was one seedling vine that stood out for its health and resistance to disease that struck the other vines. Later he named it Kay Gray and introduced it 1981.
Lay down vines on ground in autumn before snowfall. This is a successful and recommended technique for cold climate grape growing to protect vines from extreme cold.
