I'm going to be moving to Paris, France around August and have historically had little success finding American IPAs there. My current survival plan requires me to start brewing my own. I've done a little bit of poking around and it seems as though I can get some ingredients via http://www.brouwland.com/en/ . I'm also considering shipping a decent supply of Malt Extract with my possessions, but am concerned about the shelf life of these products. Does anyone have any idea how long the extracts should remain fresh for?
