I agree that it was real wine at the wedding. I think it's obvious.
I don't understand why people get so hung up in the churches about alcohol. Too much alcohol is the same as too much food, although just comes with much worse consequences sometimes. But they are both the sin of gluttony. We don't have to abstain from alcohol, we are just not suppose to be irresponsible gluttons with it. You are shocked I just said all that about responsibility, aren't you? But you shouldn't be. I do believe in responsibility and never said the contrary. :)
