Wine is made from grapes. I do not know if an instance that"wine" and "grape juice" were different words in Hebrew or Greek....probably as grape juice with no alcohol dod not exist at that time (a word for something that did not exist was not needed).Wine is made from the juice of the grapes.
Mark 2:22, And no man putteth new wine into old bottles: else the new wine doth burst the bottles, and the wine is spilled, and the bottles will be marred: but new wine must be put into new bottles.
Grape juice without alcohol did not exist in the ancient world. It was not until the temperance movement of the 19th century that pasteurization was used to prevent grape juice from fermenting.
Pretend you are living in that day. You press the grapes. You put the juice in wine skins. As you are pressing the grapes fermentation is starting to work (the yeast from the grape skins and the air are entering the juice). You put the wines in skins (or barrels).
The next day the wine is at 1% to 3% ABV. It is no longer grape juice but has become wine (a weak wine). It has the alcohol content of a light beer.
The alcohol content of fully fermented wine is estimated to be 10% to14% ABV. It had to be enough to be considered help make water safe water as in ancient Rome wine often added to water (3 parts water, 1 part wine).
Often at festivals and weddings wine was served in the first stage of fermentation (3% ABV, content like a light beer....new wine). It would have had a slight fizz to it. A person could get drunk on new wine (the juice of grapes that were put into barrels or skins the day before to several days afterwards). But they would have to drink a lot. Stage 3 you get the alcohol content of a beer (4-9% ABV) and a lot of fizz. Sage 4 you have what we think of as wine (10-14% ABV, all fermentation stops, not fizzy).
So the historical (and scientific) answer (one based on facts) is both sides are normally a bit wrong.
1. Those what want "wine" to mean graoe juice are wrong. New wine had approximately 3% alcohol. Grape juice would have only been consumed during grape trending. During this process yeast is naturally added to the juice and by the next day you have alcohol (not yet fixing but active). The only non-alcholic grape juice was when the juice wss made into a very thick syrup by cooking it, then it could be added to water to add flavor. But this was not wine (definitely not new wine). New wine was wine before active vinification.
2. Those who want "wine" to mean modern wine are wrong. In the ancient world wine always contained alcohol. But it was not classified by alcohol content. Wine was classified by other properties. So wine could be anywhere from 3% ABV to 14% ABV and simply be wine. New wine was the 3% ABV (before active vinification) and one glass would be oxidized by the body in about 30 minutes. One would have to drink a lit of new wine fairly quickly to become drunk.
We kinda use the same type of wording. Beer can ve ultra light, light, regular (?...not sure the name) or an IPA. They are all beer. But you would have to drink a lot of ultralight beers quickly to become drunk. You would have to drink only a few of IPA's.
