Everyone, put on their seatbelts

Imho, Luke 7 isn't referring to Jesus drinking wine at all. Imho, his words prove the opposite when referring to John the Baptist
Luke 7:33 For John the Baptist came neither eating bread nor drinking wine, and you say "He has a demon".
Jesus was saying there is absolutely no reason for the Pharisees and Lawyers to question John the Baptist since he did not partake of the wine ( mind altering poisons) or bad (stale or old) bread. So don't accuse him of acting goofy
Luke 7:34 "The Son of Man has come eating and drinking, and you say, "look, a glutton and winebibber, a friend of tax collectors and sinners!"
So it seems clear (to me) that Jesus was NOT drinking any alcoholic beverage because Jesus is mocking those who call him a winebibber.
Think about it. They COULD be justified in calling him a winebibber IF he WAS drinking a mind altering substance such as wine. But he wasn't so that is why Jesus mocked them for it.
