Miller High Life Gluten Test

As a result of the recent poll I promised to test two famous American beers – Miller High Life and Budweiser. I started with Miller which had the best taste of the American beers I tested so far. The reason might be the stronger alcohol as the flavour carrier which Miller contains compared to the two light beers with less alcohol I tested so far: Busch and Bud Light. Anyway, here is the Miller High Life gluten test result.

Beer: Miller High Life
Producer: Miller Brewing Company
Originating country: USA
Brewing location: USA
Bottle size: 12 oz = 0.355 l
Alcohol by volume: 4.7%
Ingredients: water, barley malt, hops, yeast
Miscellaneous: Ingredients listed in German as product sold in Germany

Test Kit: GlutenTox Home Kit

I tested with a threshold of 5 ppm. The limit of detection depends on the number of drops taken from the extraction solution, please find some more information here.

Test result: The test is negative. In this test Miller High Life has less than 5 ppm gluten (or even no gluten).

Despite the fact the test doesn’t indicate the presence of gluten above a level of 5 ppm please note this is not a medical advice – as all other tests on my site aren’t.

Please also refer to MillerCoors FAQs where they state the following:
“Gluten and non-gluten proteins are found in wheat, rye and barley. Because of the brewing process itself and filtration, beer made from barley malt does not contain large amounts of protein; however, some protein is essential for beer quality. Therefore, there are some proteins and trace amounts of gluten in our products. We recommend that anyone with gluten sensitivity not consume any of our products without prior discussion with their doctors.”


Poll: Which American beer do you want me to test next?

      Hi Franklin, we never give medical advices here. In this test the level is between 0-5 ppm and the official level of gf products is 20 ppm (at least in Europe). But it’s just a test with a home test kit, so nothing scientific and just gives an indication about the gluten content of the beer.
      I and many others are OK with these test results and can handle low gluten levels. But if you have a severe form of CD you should avoid barley containing beers. I am also diagnosed with CD but never had any effects with the beers I tested negative here. I guess the hidden gluten in products like sauces causes more problems than the low gluten in beer.
      Cheers Steffen

    I can have gluten. I have a wheat allergy ONLY. Can I safely drink Miller High Life?

      Hi Kj, most beer contain barley – like Miller High Life, so if you ‘just’ have a wheat allergy it should be safe. The only thing which might kill you is the alcohol if you drink too many of them ?
      Just be careful with wheat containing beers like many of the Belgian beers. The protein in wheat which causes the allergic reaction is Alpha Purothionin (Tri a 37) according to my internet research. But in beer this protein might be fragmented already. Anyway, barley containing beers should be safe for you – but as usual please don’t take any of our tests as a medical advice. In doubt ask you doc.

      Cheers Steffen

    This website really helps me drink more beer. I struggled to afford the gluten free beers for years now I can use your site and buy cheap beer. I can even share the 30 pack with friends and not have to explain why I’m so special.
    thanks Bro

      Hi Pete, I like the idea with sharing the pack. Sharing is caring 😉 . But for yourself don’t push it and be careful.

      Cheers Steffen
