i don't drink beer to know how well it would work (like affect the taste or whatever), but gatorade makes a bottle for one of their sizes that fits in a water bottle holder. has a twist top and all to make it convenient as a regular water bottle. a buck apiece depending on where you get it. empty and wash one out and pour your beer in it.
edit: oops, sorry. just noticed not only is it an old thread, i wrote the same answer back then too.
