I just don't think I could pour vinegar over good fresh peaches.
That said I had something kind of like it but very different seems they put peaches in a jar and poured something called fire water or shine or something like that into the jar with the peaches and sealed it up then you opened it and drank the liquid but instead of pickling the peaches it seems this pickled the drinker

seems I remember them doing about the same thing using apples and cinnamon sticks.
