I'd like any guesses to the type of grape, it was the best grape I've eaten.

It was a small red grape with seeds, but they were very small seeds. It had a slip skin. It was raised on a Michigan farm and appeared for sale over here in season, in a package with white grapes and black grapes, and there were never very many of the little reds in each package.

I have no idea how to describe tastes all that well or how many types of grapes there are, if guessing this would be possible.
