Foster’s Gluten Test

Foster’s is probably the most famous Australian beer and sold worldwide. In Australia the people may prefer other beers but it is quite famous in English pubs and during my recent trip to Detroit I could find it there in mals and stores as well. Fostes brews worldwide under licence so the beer I test here is the US version of Fosters and so gluten test results of Fosters can vary depending on the brewing location.

Producer: Foster’s Group
Originating country: Australia
Brewing location: USA
Bottle size: 0.75 l = approx. 25 Oz.

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: There is no indication of the presence of gluten above 5 ppm. According to the instructions there should appear a clearly visible red test line on the right of the test area ( T ) to indicate the presence of gluten. The blue line on the left test area ( C ) is a control line and indicates that the extract/sample is suitable, the test has been performed correctly and all reagents are active. Please don’t take any of my test results as a medical advice – see my facts page.

    Many websites claim that Foster’s contains GMO corn syrup. With all the thousands of beers available, this is one I will avoid.

    But thanks for testing this widely-available beer. Serious celiacs should be aware that the Gluten in Beer webmaster’s test showed this beer exceeded the 20 ppm threshold. I think he lives in Los Angeles, so his beer likely came from a different brewery.

      I must correct my previous post. I think all American Foster’s beer is brewed in Texas.

  2. G’day again folks…I used to drink Fosters Lager many years ago, pre Coeliac in 2010. Not bad, good summer drink. These days it is rarely found in ‘watering holes’ in Australia. I was unaware it was made with corn in USA. Have to check out Fosters Aussie site re same. Carlton & United Breweries used to own Fossies here, not sure who does now. I have just about given up drinking any beer, apart from Coeliac issues, Gout hits me bad, so just drink mainly cider (Strongbow/Magners) or Wine.

    Regards to all.

  3. Thanks Steffen and Dogbite Williams. Yes I currently miss the beer even GF stuff, but some great apple ciders out there. English THATCHERS is my favourite. I wioll sneak in one or two beers a week though, one of Steffens tested ones. Going to USA in November, couple of Buds will do me no harm.

    Regards to all.

      And Les, while you’re there try Brooklyn Lager. It’s so nice.
      I’ve just come back from two weeks in Malaysia. Only had Corona and Dutch Heineken there, plus quite a few gin and tonics. Yum.
      Cheers.

    Steffen, what a great site. Well done you for coming up with such an original take on the whole Gluten thing. I am a beer lover from the UK, I grew up on lagers (Belgian Stella, Primus, Pilsner Urquell) but then moved over to American type craft beers about five years ago. But, beer really doesn’t seem to like me and after years of on-going health problems (skin problems / autoimmune symptoms) I have now decided to cut all wheat / gluten out of my diet. What a difference it has made. But cider / wine, my usual staple these days, I do tend to glug a bit quickly, which is not great because of the higher ABV. So I have decided to return to beers (lagers I guess) with a low Gluten PPM, and will see how I do. Most specific Gluten-free stuff I have tried tastes pretty poor. Brewdog Vagabond tastes really good as a hoppy IPA although I would be interested to know its score. Anyhow stumbling upon your site was a God-send, so thanks again and keep up the good work.
