Also know as Cask Ales. This means that no artificial industrial gas has been added to our brew due to that our beer includes a secundary natural fermentation process, in which the yeast is kept alive inside the bottle all the way until the very moment you drink it. The yeast in the bottle naturally carbonates the brew which extends it´s lifespan while also preserves the aromas. This gives our beer a more real taste and feeling than ordinary beer!
