We see in:
Hosea 4:11 “to prostitution; old wine and new wine take away their understanding”.
Joel 1:5 "Wake up, you drunkards, and weep! Wail, all you drinkers of wine; wail because of the new wine, for it has been snatched from your lips.
Acts 2:13 (King James Version) Others mocking said, ‘These men are full of new wine’.
No one becomes intoxicated, or is considered a drunkard by consuming grape juice. It appears that even “new wine” had alcohol content, based on these verses. Indeed, the very definition of wine is fermented juice.
