Life Style / Wine Grapes / Ventura: Cold hardy to -25 deg. F. (ca -32 C.) American hybrid developed in 1974 by the Ontario Horticultural Research Institute of Canada. Is a cross between the Elvira V. Riparia variety and Chelois. Has improved resistance to fruit cracking. Recommended as suitable for making crisp labrusca-flavored wine, or juice production. Ripens late September, with berries that are high in sugar and acid content if left past maturity. The vine has some susceptibility to tomato ringspot virus and requires grafting if grown on virus-infected sites. Currently grown in Canada, S. Dakota and other mid-west U.S. states.
