Back in 2009, the Scottish BrewDog brewery released a 32 ABV beer called Tactical Nuclear Penguin.The made it just to swipe the "world's strongest beer" title from Germany's 31 ABV Schorschbrau Schorschbock.The Scots and the Schorschbrau brewery traded the title several times over the coming years.But the rivalry ended in 2011 when the Germans dropped a 57 ABV that brought the Scots to their knees.But BrewDog and Schorschbrau hadn't forgotten. And to honor their previous battle, the brewers have collaborated.Strength in Numbers is a 57.8 ABV beer made with Schorschbrau's eisbock method, and it uses Brewdog's ice distilled, 10-year cask aged ale.Strength In Numbers was released on September 17th, in tiny 40-milliliter bottles with a big $38 price tag.
