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.

    Thanks for doing the research. It’s appreciated! I’m going to try 4 oz and see what happens.

      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
