I’ve heard friends who have actually bought grapes peeler! But no you honestly don’t need that many fancy tools to stuff your kitchen drawers. Peeling grapes is not a fancy preparation for fruits, if you’re making grape jello it would be better to use skinless grapes for sure.
Elongated seedless grapes would be easier to peel than the round ones, and just peel around the grape with, your fingers! Don’t try to peel it from top to bottom because the skin can actually rip before you get to the end.
