100 Gluten Tests

100 Gluten Tests lowgluten.org

With the previously released Rothaus Pils Gluten Test we conducted the 100th test on beer. Thanks to all contributors to make it happen.

We have tested 91 beers in total, a number of them more than once and partly with both available test kits, hence the difference in conducted tests vs. number of beers we tested.

Here are some statistics: 65 of the tests were completed with the GlutenTox Home kit from Biomedal and 35 with Imutest’s Gluten-in-Food kit. We tested beer from 24 different countries – most of them from Germany. Please find a table with all countries at the bottom of this post (click on Read More). The tests were done by eight people, seven male and one female – I am really thankful for the contribution of these guys.

Well, it’s now time for me to let loose. I will not stop posting results but I will focus on different things. So far I always tried to post at least one test per month but from now on I will just post from time to time. Next goal is the achievement of 100 tested beers but as I said I will not push to achieve this. It comes when it comes. I will keep the site alive of course as the number of gluten sensitive people or people with CD is still growing as well as the number of visitors grows. Your donations will help to keep the lights on and contributors are always welcome.

Cheers Steffen

Rothaus Pils Gluten Test

A nice German beer from the Black Forrest is the Rothaus Pils. I am not so sure if it is available outside Germany but in Germany people like it and it is also much more expensive than other mainstreams beers like Warsteiner, Beck’s or Bitburger. More common than the 0.5 l bottle is the smaller version with 0.33 l called Tannenzäpfle (pinecone). But it’s the same beer and gluten level seems to be OK too, see test result below.

Beer: Rothaus Pils
Producer: Badische Staatsbrauerei Rothaus
Originating country: Germany
Brewing location: Germany
Bottle size: 0.5 l
Alcohol by volume: 5.1%
Ingredients: water, barley malt, hops
Miscellaneous:

Test Kit: Imutest Gluten-in-Food Kit

Test result: The test result is negative. According to the instructions there should appear a clearly visible pink test spot on the left of the test area ( T ) to indicate the presence of gluten. The pink spot on the right test area ( C ) is a control spot and indicates that the extract/sample is suitable, the test has been performed correctly and all reagents are active. Even though the detection limit in this kit is very low (1-2 ppm) and the is negative please note this is not a medical advice – please see also my facts page.

Spaten Oktoberfestbier Gluten Test

During the famous Oktoberfest time a lot of the breweries brew a special beer which is only available during that time. This normally has higher alcohol content and is so very tasty as alcohol transports the taste in beer. Well, that’s also why I don’t really like alcohol free beer. Anyway here is the gluten test of Spaten Oktoberfestbier. I saved two bottles I bought in Oktober in my basement to enjoy them later. Despite the result below (*spoiler warning*) I had no reaction on it.

Beer: Spaten Oktoberfestbier
Producer: Spaten-Franziskaner-Bräu Munich
Originating country: Germany
Brewing location: Germany
Bottle size: 0.5 l
Alcohol by volume: 5.9%
Ingredients: water, barley malt, hops, hops extract
Miscellaneous:

Spaten Oktoberfestbier Gluten Test Spaten Oktoberfestbier Gluten Test

Test Kit: Imutest Gluten-in-Food Kit

Test result: There is a clearly visible pink test spot on the left of the test area ( T ) which indicates the presence of gluten. 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 ). Please find some more information here.

Spaten Oktoberfestbier Gluten Test

On a scale from 1 to 20 I would rate the test spot intensity 3. As Imutest uses the R5 antibody since a while it is difficult to estimate the gluten level in ppm in comparison to Skerritt antibody they used earlier, hence I will mark the test just positive. Even though this test is positive please note it is not a medical advice – see my facts page.

Zillertal Märzen Gluten Test

During my last ski holiday on the Austrian side of the ‘Zugspitze’ (the highest mountain in Germany) I found a nice Austrian beer which I liked very much. It is not really local from that place but it is also not so much a mainstream beer like Gösser.

I decided for the Zillertal Märzen rather than the Zillertal Pils as the Austrian Märzen is close to Lager. The definition of Märzen in Germany is very different to the Austrian as the German Märzen is stronger in alcohol and more hoppy. Anyway, here is the gluten test result of Zillertal Märzen:

Beer: Zillertaler Marzen
Producer: Zillertal Bier GmbH
Originating country: Austria
Brewing location: Austria
Bottle size: 500 ml
Alcohol by volume: 5.1%
Ingredients: water, barley malt, aroma hops
Miscellaneous:

The pink spot on the right test area ( C ) is a control spot and indicates that the extract/sample is suitable, the test has been performed correctly and all reagents are active. Even though the detection limit in this kit is very low (1-2 ppm) and the test is negative please note this is not a medical advice – please see also my facts page.

Tiger Gluten Test

This is a very much requested test. Many people asked for this already. During one of my last trips I grabbed a Tiger can and took it home to test it on gluten. Taste is quite OK. Nothing special, probably best enjoyed in Asia when the weather is hot and the beer cold.

Beer: Tiger
Producer: Asia Pacific Breweries Ltd
Originating country: Singapore
Brewing location: European Union
Bottle size: 330 ml
Alcohol by volume: 5.0%
Ingredients: water, malted barley, maize grits, hop extract
Miscellaneous:

Tiger Gluten Test Tiger Gluten Test Tiger Gluten Test

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.

Tiger Gluten Test

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.

Samuel Adams Boston Lager Gluten Test

Another famous American beer and something many visitors probably waited for a long time is Samual Adams crafted Boston Lager. Well, what’s the definition of craft beer? In my eyes it’s a beer produced by an independent small brewery selling it almost only locally, preferebly run as a family business and the boss checks the quality daily with passion and dedication. Boston Lager is to me more a mass production beer produced by a S&P listed company with almost 1 Billion $ revenue. Here is a nice little article about Sam Adams. Maybe I am wrong so I would be happy to see comments with your opinion

But what about the gluten concentration in Boston Lager? Here is the test result:

Beer: Samuel Adams Boston Lager
Producer: Boston Beer Company
Originating country: USA
Brewing location: USA
Bottle size: 12 oz = 0.355 l
Alcohol by volume: 5.0%
Ingredients: water, malt, hops, and yeast (internet research as ingredients are not listed on the can)

Vote on professional gluten tests

I recently had a chat with Karlo, a gluten intolerant visitor of my website from the Netherlands, who came up with the idea of testing beers in professional laboratories with professional methods, like the Competitive or Sandwich ELISA test. Compared to the home test kits we use there could benefits in getting certified results and have comparable results to the tests we made already. There is of course controversy which test method (e.g. Competitive vs. Sandwich vs. Lateral Flow Trough) or antibody (Skerritt vs. R5 vs. G12) is the best. However, the more and the more professional we test the better results we get. And now the downside: the costs are very high: between 100-110 USD (85-95 EUR) per beer per test. Nutrilab in the NL offer such services: https://www.nutrilab.nl/en

Below you find a vote on whether you would be willing to donate money for tests and what would be your limits.

In case of a positive result of the vote we can start some sort of crowdfunding and collect a certain amount of money to be used for the tests. We don’t know yet how to decide on the beer to be tested – most likely per vote again.

Please note, this is a non-profit site and non-profit idea. All the money would be used for tests. Use the comment function for discussions.

How much money would you donate for professional beer tests on gluten?

  • Between 10 and 25 USD (38%, 25 Votes)
  • Less than 10 USD (20%, 13 Votes)
  • Nothing (17%, 11 Votes)
