* Though standards vary from country to country, according to the FDA, "In order to use the term 'gluten free' on its label a food must meet all the requirements of the definition, including that the food must contain less than 20 ppm (parts per million) gluten." It is said that products with a gluten content below 20 ppm are suitable for people with celiac disease.
DISCLAIMER: We are testing beers out of our own curiosity at home and sharing the test results with others. We are not medical doctors and our results should not be interpreted as medical advice. We do NOT claim that ANY of these beers are safe to consume if you have celiac disease or are gluten intolerant.
