title_body: What is the proper way to open a bottle of Delirium Tremens?
upvoted_answer: The cage is simply twisted closed.   You'll see that bottom wire is twisted tight and bent upwards.   Simply bend it back down to horizontal, and untwist to loosen the cage.  At that point you'll be able to lift the cage free, and un-cork by hand.  It's been a year or two since I've had a bottle of Delirium Tremens, so I don't remember how tight the cork was, but certainly some beers that are corked and capped like this do have corks that are fairly resistant to removal.  If that is the case for your bottle, then I find that twisting the cork as I pull up will generally free it nicely.
