I know from experience you can only bring in ONE liter - I had two, so I had to pay an extra $20 - the guy at security just asked me to "estimate" my second purchase (!!) so I think I said $20 (I had a $20 bottle of whiskey and a $32 botle of Grey Goose) - who knows where the math comes into play, but if you really gotta have it, just pay a little extra. (I was brining these for people - I like Belikin) Find people to help you! As for wine at Dury Free, I don't know but I am sure you can call an airport and ask.
