i see what you're getting at...and i believe your point of view is plausible. i'm just saying that the other is equally plausible and defensible as well. fermentation doesn't HAVE to be a part of it but it COULD be. plus it doesn't explain why master of ceremonies would make a comment like "...too much to drink". how does that phrase make any sense if we're talking about regular juice??? sorry but i don't see it...

besides, 180 gallons of any kind of juice or even water is plenty for folks to be drinking, lol. unless the bride was real popular and she had hundreds and hundreds of guests
