The red grape variety (breeding number Gladwin 3000) is an interspecific new variety between Fredonia x Worden(Concord - open-pollinated). It contains genes from Vitis labrusca and Vitis vinifera. The hybrid was crossed in the early 20th century by grower Fred E. Gladwin at the Grapevine Breeding Institute of Cornell University in Geneva, New York. The variety was introduced to the market in 1935.
This very early-maturing vine, which is frost-hardy to minus 20 °Celsius, is susceptible to downy mildew. It produces fruity red wines with foxy, but is mainly used as table grape.

In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
