World's strongest beer

The world's strongest beer (in terms of alcohol content) is called Tactical Nuclear Penguin, brewed by BrewDog brewery, a 32% double cask matured uber-imperial stout.

The beer also comes with a warning on the label

This is an extremely strong beer; it should be enjoyed in small servings and with an air of aristocratic nonchalance. In exactly the same manner that you would enjoy a fine whisky, a Frank Zappa album or a visit from a friendly yet anxious ghost.

See BBC News. With such a high alcohol content, does it have to be drunk cold?
