BrewDog claims to have made a 55% ABV "beer" which they call The End of History. They have other high ABV "beers:" Tactical Nuclear Penguin is 32% ABV and Sink the Bismark! is 41% ABV.
From what I understand, each of these beers starts with a normal recipe for a high ABV (imperial) beer, but this can only get you so far. The high ABV is obtained by freezing the beer, scraping off the ice, and repeating. The result is a high alcohol content liquid.
Usually, I would call beer that has been processed in this way "ice beer," but I'm not sure the label applies at this extreme.
My question: Is The End of History beer?
(Note: This should be considered separately from the question "Is beer the end of history?")
