Michelob Ultra Gluten Test

Michelob Ultra is ranked 8th of the best selling beers in America in 2013 (see here the Top 20). It is a typical American light beer with a watery taste but generally OK as it was not as sweet as other American light beers, a bit like a light European style Lager beer. The level of gluten is very low, see test result below.

Originating country: USA
Brewing location: USA
Bottle size: 16 oz (approx. 470 ml)

Test Kit: Imutest Gluten-in-Food Kit

Test result: There is a barely visible pink test spot on the left of the test area ( T ), almost not visible in the picture but it is there. According to the instructions a “very low gluten” level of 20 to 100 ppm should give a test spot which is weaker or similar in intensity to that of the control spot ( C ).

On a scale from 1 to 20 I would rate the test spot intensity 1. The spot is hardly visible so it seems the gluten level is very, very low as the test kit also has a very low detection limit. Please find some more information here. Even though this test is low positive please note it is not a medical advice – see my facts page.

      Hi XLI, how was your test? Any reaction? Cheers Steffen

        I am overly sensitive, as in can’t eat “made in a facility…” anything. Holiday Reese’s are terrible on me, but they were no trouble before the day I turned sensitive.
        I know if something has gluten in minutes, before I finish that meal.
        TMI, but my experience was 2/3 of one of those taller cans of this beer, 10oz estimated consumed, and I had a minor “hey what was that” for a minute and it went away shortly after.

    Awesome to see this test, I have celiacs disease and someone mentioned they heard these could be a potential option. I have been drinking them for a few months now and do not have a reaction when drinking.

    I’m trying to stay away from gluten but I love to have a few beers. I was told Corona was GF? I do hear it does have a little. How does the Michelob Ultra compare to Corona as far as gluten?

      Sorry to hear Sandra. Please read the result carefully: “…so it seems the gluten level is very, very low”. If you suffer from tiny amounts of gluten already better stay away from barley containing beers. Cheers Steffen

    I’m gluten sensitive, not celiac but this is my go-to. It’s not a strong beer but I enjoy the flavor A LOT compared to other options and it’s never made me feel bloated or in pain AT ALL.
    Your mileage may vary of course, best of luck everybody!

    If any of you out there are taking Levothyroxine for your thyroid, it does not like Gluten, at all! I was tested for Celiac disease and it came back negative. Then, when at a party, the subject came up and the person I was talking to said “eliminate gluten and your problems will go away. I did, and she was correct! So if you think you are allergic, it might be the Levothyroxine.
