I don’t think…. Raw wine grapes are actually edible lol

Why not?

You can eat them, but they like… have a lot of seeds, thick skin, and are pretty astringent

I was like 10 years old and my parents visited family friends of ours. I was out back and all these awesome looking grapes were growing on the fence. I took a bunch and ate them…..yuck . They told me they were wine grapes, lol. Instead of the sweetness of regular grapes, they tasted kinda sour, vinegary and ferment.
