The BBC reports that Brew Dog, one of Scotland's cutting-edge microbreweries, has just re-staked their claim to the world's strongest beer with "Sink the Bismarck," at 41% alcohol by volume. Brew Dog's earlier entry in the strongest-beer arms race, "Tactical Nuclear Penguin" (32%), was bested by German brewer Schorsbrau's "Schorsbock" (40%).
In addition to strange names, Brew Dog also produces some really good beer. Their flagship, "Trashy Blonde," is a fine pilsner, and "Punk" is a fine IPA. But as Nana said, once you get too far into the double digits for alcohol content, are you really still talking about beer?
