I had never even thought of the possibility of there being such a thing as grape jam...
Strawberry, Raspberry, Blackberry and other things like that, yea, but grape doesn't seem like something you would be able to make into a jam. This 'Grape Jelly' stuff you speak of seems closer to what you call 'Jello' than what we call 'Jam'
And so I have the question: Is 'Grape Jelly' made from real grapes or just grape flavour?
