“And That is when Jesus changed the water into pure unfermented grape juice!”
Best counter I’ve seen was the remark in Scripture of the guest at the wedding who exclaimed, Why did you hide the best wine until last? Custom was for the best wine to be served first, then after people had a few drinks, imbibed, and not quite as discerning, feed them the lesser wine and nobody would know the difference.
IMHO, while daily consumption may have been a grape juice, when they sat and imbibed with wine,...it was probably a better wine than we drink today.
