title_body: When was non alcoholic wine first invented?
upvoted_answer: I'm sure the "Ancients" drank grape juice. It was probably a delicious treat when it was in season when the grapes were ripe in the Fall. I love drinking the juice from my wine grapes, it's very good! But, without filtration or sulfites, there was no way to store grape juice without spontaneous fermentation, even after boiling it. Eventually something would turn it into wine or vinegar. So, you always ended up with wine whether they wanted it or not. So, yes, they probably drank grape juice, but only for a short period after harvest time.
