                                According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), a 40-fluid ounce bottle of malt liquor can contain up to 4.7 standard drinks, significantly more than a 40oz of regular beer. Determining exactly how many beers is a 40oz equal to depends heavily on its alcohol content.
