Stone Delicious IPA by Stone Brewing Co.:
Stone has always been obsessed with brewing bold, high-quality craft beer. When we developed this pleasantly bitter, deliciously lemony IPA, we took it as an opportunity to do something we’d spent over a year researching and perfecting: reducing the amount of gluten in the beer* to the degree that nearly everyone could experience our no-holds-barred approach to craft brewing.
An enzyme added during the brewing process called Clarity Ferm did the heavy lifting, cutting the beer’s gluten content to well below the threshold of 20 parts per million required by the Food and Drug Administration to label a product “gluten-free.” What it did not diminish—by any stretch—was this IPA’s flavor.
