"Verboten Brewing derives its name from the “forbidden” ingredients that were rejected by the German Purity Law for beer, the Reinheitsgebot. Under the purity law, beers could only be made with three ingredients: barley, water and hops. Yeast, once its fermentation properties were clearly understood, was added later. Verboten’s beers will embrace the trend of incorporating fruit and spice, barrel aging and other distinctive ingredients and processes to make our craft beers."
