Clausthaler uses a carefully guarded, patented process to prevent the formation of fermentable maltose. Once that's done, beer yeast that's been specifically cultured for Clausthaler is added to the brewing process. The result is a low-alcohol beer (around .45 percent, by volume) that has all the flavor of a classic German lager. It's a crisp and refreshing beer, with a pleasant bitterness that will have you forgetting that you're drinking an n.a. after a couple sips. The crisp flavor of Clausthaler also makes this beer a perfect complement for summer cookouts.
