I disagree with some of these questions. 2.5 lbs of grapes to make one gallon??? I dont think so!!! I got 13. As for the Champagne question I got that right as Ive done a lot of reading on that but also know that is only for very high priced Champagnes and that most cheaper bottles on the shelf are not these types or actually a blend of one of these listed and some other not listed as most Champagne is made from inferior wines due to the carbonation hiding many flaws and making a bad wine taste decent or even good.
