BrewDog have fired the next shot in their ongoing battle with Schorschbräu for the title of Strongest Beer on Earth with the release of Sink the Bismarck, a quadruple IPA that contains four times the hops, four times the bitterness and frozen four times to create at a staggering 41% ABV. You can read more about the beer on their blog. Whether you like their beer and their brewing philosophy or not, they do make pretty funny videos.
However, this ongoing one-upmanship for strongest beer seems pretty pointless. Utopia from Sam Adams was a cool novelty when it was released in 2002, but now this is just getting boring. It obviously gets the two year old brewery more publicity, but really doesn't entice me to drink more of their beer. I have tried a couple of their beers that are available down here and wasn't very impressed... with the beer or the high price.
They've apparently been getting a little beaten up about it and you can read their response here on a BeerAdvocate forum.
*** UPDATE 02/19/010 ***
Apparently the war rages on... Schorschbräu has announced it will release a 45% ABV beer very soon. You can read an English translation of a German article on The Bitten Bullet blog about Schorschbräu's reaction to Sink the Bismarck and their announcment to beat it.
"I wish there to be fair competition," said Tscheuschner. He himself would soon bring out a beer with 45% by volume of alcohol.
Perhaps they can bring an end to this by brewing a collaborative 50% ABV beer and just call the whole thing done.
