Just saw yyour post, and have to say that those are wild grapes that growing up we always called coon grapes. Coons and birds love them, and they make very good jelly, but the wine is a lot lubruski! I have made wine from them, and if the critters left them alone long enough to get the brix up, would be so so. A lot of people still make wine from them, but the people that do are not wine drinkers! lol.
