I received a bottle of Delirium Tremens for my birthday and this will be the first time I have tasted that beer. I see that it has what appears to be a cork which is surrounded by 4 wire posts at the corner. The following site (of some random person I don't know) has an image of a bottle looking very much like my own.
So that I don't mutilate what is sure to be a wonderful beer, how should I get about opening it?
