Life Style / Wine Grapes / Janesville: Reported as thought to be a V.labrusca/riperia variety allegedly derived from a Hartford x Clinton cross in Wisconsin around 1860. Vigorous and productive with excellent cold-hardiness. Fully ripens a little earlier than Concord, although it colors much earlier, to give medium-small size dull-black berries that can produce an indifferent red wine. No other details as yet.
