I definitely get the freshness factor, taxy. Someone here on DC said that once they open a gallon of milk, they pour it off into smaller containers. It seems to stay fresher when you don't expose the entire gallon to the air each time you take off the cap. Well, I have plenty of "souvenir" glass bottles from buying farm fresh milk years ago - half gallon, quarts, pints. Two of the pints are actually from some upscale salad dressing that Himself liked. They have screw-on caps rather than ones that just pop on. I can hide four pint bottles against the back wall of the fridge, then have the three quarts where the gallon used to be. Well, now just one quart since I've been buying mostly half-gallon jugs. Anyway, this method actually does seem to keep the milk from going off later in it's life span.
