Prototype Series 2012 Our annual prototype challenge sees us brew a series of new beers, and allows the public to choose which should feature alongside our headliner range. A hoppy, dry hopped low ABV reasonably malty pilsner. At 4.2% this amber hued little gem infuses wholesome BrewDog hoppiness with classic lager sharpness. Best enjoyed whilst whistling the European Union’s national anthem (does it have one), munching on a bratwurst and planning a weekend trip to Prague whilst listening to the Beastie Boys.
