Of course Jesus drank wine, the scriptures are entirely clear on the matter. At Cana the master of the feast even remarked on the suerior quality, contrasting it with the poorer wine first on offer. Normally, he said the better wine is given first until people have drunk so much they can't tell the difference between the good stuff and the inferior. What does that tell you? The good wine was sufficiently intoxicating to dull the senses enough not to notice the switch.
Then there is the Last Supper or Pesach Seder. In Matthew 26:29 Jesus said: 'But I say to you, I will not drink of this fruit of the vine from now on, until that day when I drink it new with you in My Father's kingdom.'
'From now on', tells us that it had been his custom to drink it hitherto.
Also, Jesus was an adherent Jew who kept the Law perfectly, including Yahweh's command concerning the observance of the Feast of Tabernacles in Deuteronomy 14:24-26:
'And if the way is too long for you, so that you are not able to carry it, or if the place is too far from you, which Yahweh your God shall choose to set His name there, when Yahweh your God has blessed you, then you shall turn it into silver and bind up the silver in your hand, and shall go to the place which Yahweh your God shall choose.
And you shall pay that silver for whatever your soul desires, for oxen, or for sheep, or for wine, or for strong drink, or for whatever your soul desires. And you shall eat there before Yahweh your God, and you shall rejoice, you and your household and the Levite within your gates, you shall not forsake him, for he has no part nor inheritance with you.'
If you check out the Hebrew for 'wine' and 'strong drink' in verse 26, they are 'yayin' and 'shekar', which mean 'fermented wine' and 'intoxicating liquor'.
Indeed, God had so little problem with alcohol that he even told his people not just to buy themselves a drink but to be generous and buy a round so that everyone might rejoice before him.
People who drink too much get drunk. People who eat too much get obese. People who sleep too much get lazy. Just about anything in excess is sinful, but we should not therefore conclude that all that is sinful in excess is sinful in every circumstance. Certainly God does not have aproblem with alcohol, although alcohol has a problem with some people.
