Goose Island: The best beer by far that comes in a stupid twist off bottle IMHO.
The foil on Samuel Smith bottles and the whole dang label on Black Dog just doesn't want to come off. I've stopped using those two, but everything else I've tried soaks right off in an Oxiclean bath.
Except, of course, Guinness. I think I could delabel, dewidget, clean, and sanitize a guinness bottle in 20 seconds.
