Oh?
Then WHERE did the 'cheaper' stuff come from?
Excellent! You've finally got the point that the text says there wasn't any "cheaper" forerunner, and that the caterer never said there was. The text says that it (the wedding banquet) lacked wine, and that Jesus' mother said, "They are not having wine."
(By the way, I've run this translation past a highly qualified expert in the Greek and Hebrew languages, and he agreed that my interpretation of this passage is correct.)
This is consistent with the feast-master not complaining about having to serve crappy refreshments before the best was brought out.
BTW, I have a PhD in solid state chemistry, and used to pick grapes in the vineyard of a Swiss-born wine-maker and brewmaster-consultant to a company making beverage storage vessels. Appeal to authority, heh? Truth.
