This 'World's Strongest Beer' Is a Collaboration Between Two Rival Breweries

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.Unfortunately for extreme beer fans, those bottles appear to already be gone
