I believe Arnie, the owner/operator of Markko Vinyards out east in Ridgeville/Conneaut tried growing Scups from old stock vine years ago, and had great difficulty as they don't like ohio's -10* temps...
He grew some muscedine also, and had some success....
Might want to check the vinyard out, it is one of ohio's best..... just saying,
