A Scottish brewery claims it has produced the world's strongest beer. It's called Brewmeister's Armageddon, and the alcohol content is 65 percent.

For some perspective, most beers have an alcohol content of between 3 to 7 percent.

The beer's ingredients include crystal malt, wheat, flaked oats and 100 percent Scottish spring water. The beer then undergoes a process called freeze fermenting, which involves cooling the beer to freezing. The water freezes, but the alcohol does not -- when the ice is removed a very strong beer remains.

Drinkers are advised to "consume this like a fine whisky".
