umm... Pepsi I think has come out with a "holiday flavored" soda, I heard it advertised on the radio the other day, very disparaging about egg nog too, but I think they mentioned that it was spiced like egg nog, will have to see if I can find a bottle and try it, don't sound too bad.
I make my own beer on occasion and have made holiday spiced beers, that are actually quite good (well better than you would think they would be at least).
