According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), a standard drink in the United States contains 0.6 fluid ounces of pure alcohol. When it comes to distilled spirits, the serving size needed to achieve this standard varies depending on the product's proof, a direct indicator of its alcohol content. This brings into question whether a 1 oz pour of 100 proof liquor measures up to the standard serving benchmark.
