Back in the day, there were some weird gimmicks / marketing / boundary pushing beers. And one of the weirder chapters in the craft beer history book was the high ABV battle between BrewDog and Shorschbrau. Scotland V Germany to create a beer higher in alcohol than some spirits.
There was Tactical Nuclear Penguin at 32%. Then the Germans countered with their Bock at 40%, BrewDog came back with Sink the Bismarck which tipped in at 41%. The Bock returned at 43% before The End of History arrived at an eye popping 55%.
All that is preamble to the fact that the two breweries have joined forces (via Zoom) to create a new beer. More news on what it will be is coming.
