Some information about gluten test kits

Today I want to inform you about my experiences with the gluten test kits I use to test the level of gluten in beer.

According to my doctor the toughest for men with Celiac Disease is the avoidance of normal beer as beer naturally is brewed with barley and so they believe they cannot consume it anymore. When I was diagnosed with CD I had the same reaction. I don’t like strong alcohol or wine but I really enjoyed a beer with friends. In our culture beer is a popular drink when socialising. It’s not about getting drunk but moderate consumption of beer in good company gives you a good feeling.

I gave up wheat containing pasta, pizza and bred – not so difficult for pizza but I really loved pasta and the numerous wonderful German bread types. So I said OK I gave up good food already but is it true that I cannot drink normal beer anymore and have to drink this horrible tasting and expensive gf beers brewed with artificial ingredients, glucose syrup and whatever? And now after more than one year testing beer on its gluten content I am convinced that a lot of normal beers are suitable for a lot of Celiacs. Not for all – there are people who react on the tiniest amount of gluten. But I believe the majority can drink a lot of the normal beers available without getting reactions or intestinal damage. But it definitely makes sense to test your favourite beer on the gluten level. There are a number of test kit manufacturers and here is what I experienced:

Test kit: Gluten-in-Food
Imutest Gluten Test Kit Imutest Gluten Test Kit Imutest Gluten Test Kit
Manufacturer: Imutest
Costs: GBP 52.50 for a 5 test kit
Antibodies used: Skerritt
Method: Lateral Flow Through
My experience: Sensitive test kit with very low detection limit (1-2 ppm). Works with test spot intensity to determine level of gluten.
Hints and tips:
-according to Imutest the extraction step can be skipped for beer as gluten in beer is already solubilized
-if you use the pipette to measure the sample let the beer settle in a glass for 30 minutes or so to avoid a bubbling effect when you fill the pipette
Here are some more information and pictures.

Test kit: GlutenTox Home
GlutenTox Home Kit GlutenTox Home Kit GlutenTox Home Kit
Manufacturer: Biomedal
Costs: USD 70 for a 5 test kit
Antibodies used: G12
Method: Lateral Flow Through
My experience: Reliable test kit. Works with thresholds (5, 10, 20, 40 ppm) depending on the number of drops taken from the sample.
Hints and tips:
-the extraction must not be skipped according to Biomedal however when I tested the same sample with and without extraction the result was the same
-to measure the sample use the enclosed spoon
Here are some more information and pictures.

    Estrella Daura Damm Gluten Test

    During my recent trip to Spain I had the chance to test a famous gluten free labelled beer. As I always take a test kit with me when I go abroad I supposed to test the draught beer they sold in my hotel but then I saw Estrella Daura Damm in a supermarket and couldn’t resist. The price is rather high, almost as double as the regular Estrella Damm beer but I really wanted to enjoy an officially labelled gluten free beer. Well, not everywhere – in some countries (like in the US) Damm is not allowed to label it gluten free – I guess because it contains barley. Their marketing experts instead use the fantastic wording ‘crafted to remove gluten’ in the US – well done you marketing pals. Anyway, the European version clearly says “below 3 ppm” on the bottle which moreover is confirmed by the Spanish National Research Council so this all implicitly says it is safe for Celiacs and people with GS. And this beer really tastes like beer, actually no difference to the “normal” Estrella Damm, refreshing and crisp.

    A gluten free labelled beer, below 3 ppm, researched and confirmed by a Spanish public institution and it even tastes like a real beer – everything seems to be perfect. And then happens this:

    Beer: Estrella Damm Daura
    Producer: S.A. Damm
    Originating country: Spain
    Brewing location: Spain
    Bottle size: 330 ml = approx. 12 Oz.
    Alcohol by volume: 5.4%
    Ingredients: water, barley malt, rice, hops
    Miscellaneous: officially labelled gf beer

    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. The test spot appears almost identical to the control spot.

    On a scale from 1 to 20 I would rate the test spot intensity 5 or 6 so in this test the level is above 20 ppm. Even though this test is positive please note it is not a medical advice – see my facts page.

      Miller Lite Gluten Test

      Due to a huge amount of enquiries over the contact form, post comments and directly via email I decided to also test Miller Lite despite the fact it couldn’t win the American light beer poll back in January. Thanks to all for your kind feedback.

      Please note I can do a few of your wishes but not all. It is impossible for me to test all the beer you want me to test. Very often I am simply not able to get your favourite beer here in Germany but it is also a matter of costs. I also need to pay for the test kits. Please consider to purchase a 5-test kit which is around € 60 / $ 80 / £ 50 and so you pay approx. € 12 / $ 16 / £ 10 per test which is a useful investment in your health. I have listed some gluten test kit manufacturers here.

      And here you go with the Miller Lite test on gluten:

      Beer: Miller Lite
      Producer: Miller Brewing Company
      Originating country: USA
      Brewing location: USA
      Bottle size: 16 oz (approx. 470 ml)
      Alcohol by volume: 4.2%
      Ingredients: water, barley malt, hops, yeast
      Miscellaneous: Ingredients listed in German as product sold in Germany

      Miller Lite Gluten Test Miller Lite Gluten Test

      Test Kit: Imutest Gluten-in-Food Kit

      Test result: There is no indication of the presence of gluten. 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. But this test is negative. 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.

        1 YEAR LOWGLUTEN.ORG

        Hi all, I started this website one year ago and actually did not expect this enormous feedback. It is amazing what happened during the past 12 months and I am very happy that this website is useful for so many people.

        At the beginning the majority of the visitors were German (mainly myself I suppose) but it changed dramatically. Most of the visitors are now from the US were the demand for such tests seems to be very high, but I also have lots of visitors from the UK, Australia (thanks Les ;-) ), Canada and the Scandinavian countries.

        I tested 18 beers so far (please see here an overview of all beers I tested) and I learned a lot during the last year about test kits, antibodies, beer filtration methods etc.

        There a more than 10.000 page views per month so I consider to place some little ads just to get some money back which I would reinvest in test kits. I think about using Google AdSense but I will not do affiliate marketing as I want to stay independent. There will also be no pop-ups or something annoying for visitors, just little ads in the sidebar and footer of the page.

        But I don’t want to scare you off with the ads so I ask you before I do that:

        Would you still visit my website when I place some ads?

          Tsingtao Gluten Test

          Clear winner of the recent Asian beer poll was Tsingtao, a Chinese beer from one of the world’s largest breweries – founded by German settlers at the beginning of the 19th century. The taste is actually good – refreshing and crisp, not watery. It contains rice so my assumption was that it is rather gluten free but my test showed it is not:

          Beer: Tsingtao
          Producer: Tsingtao Brewery/青岛啤酒
          Originating country: China
          Brewing location: China
          Bottle size: 330 ml = approx. 12 Oz.
          Alcohol by volume: 4.7%
          Ingredients: water, barley malt, rice, hops (translated from German)
          Miscellaneous: Ingredients listed in German as product sold in Germany

          Tsingtao Gluten Test Tsingtao 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. The test spot appears slightly lighter than the control spot but almost identical.

          Tsingtao Gluten Test

          On a scale from 1 to 20 I would rate the test spot intensity 6 so in this test the level is above 20 ppm. Even though this test is positive please note it is not a medical advice – see my facts page.

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

            Asian beers are believed to have low gluten as they often use rice as one major ingredient and barely malt only to give a typical beer colour. The rate of people with Celiac Disease or Gluten Sensitivity in Asia is lower than in Europe or US mainly because of rice as the main dietary staple and simply the fact that it is underdiagnosed unknowingly. But it becomes more prevalent in countries like China and Thailand with the adoption of western lifestyle. Not only for people who live in Asia but also for travelers a gluten test of your favourite Asian beer might be useful. Please vote below which of the following four famous Asian beers  you want me to test next:

            Chang: from Thailand
            Singha: from Thailand
            Tsingtao: from China
            Tiger: from Singapore

            Which Asian beer do you want me to test next?

            • Tsingtao (33%, 51 Votes)
            • Singha (27%, 41 Votes)

              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.

              Beer: Michelob Ultra
              Producer: Anheuser-Busch
              Originating country: USA
              Brewing location: USA
              Bottle size: 16 oz (approx. 470 ml)
              Alcohol by volume: 4.2%
              Ingredients: water, barley malt, hops, yeast (translated from German)
              Miscellaneous: Ingredients listed in German as product sold in Germany

              Michelob Ultra Gluten Test Michelob Ultra Gluten Test

              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 ).

              Michelob Ultra Gluten Test

              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.

                Moosehead Gluten Test

                This is the first test of Canadian beer. Moosehead is not the best selling beer in Canada but I gave it a try as one of my website visitors told me that Moosehead, Labatt and Molson are the most common beers in Canada. Well, honestly I didn’t like it as it has an unpleasant sweet taste. But taste differs and here is the result of the Moosehead gluten test:

                Beer: Moosehead Lager
                Producer: Moosehead Breweries
                Originating country: Canada
                Brewing location: Canada
                Bottle size: 12 oz can (approx. 355 ml)
                Alcohol by volume: 5.0%
                Ingredients: water, malt, corn, hops, yeast
                Miscellaneous: -

                Moosehead Gluten Test Moosehead 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. The test spot appears lighter than the control spot.

                Moosehead Gluten Test

                On a scale from 1 to 20 I would rate the test spot intensity 4/5 so in this test the level is above 20 ppm. Even though this test is positive please note it is not a medical advice – see my facts page.

                    Warsteiner Gluten Test

                    With almost 50% of the votes Warsteiner was the clear winner of the recent poll. Warsteiner is not one of my favourites and in Germany it is considered as a “ladies beer” because of it’s light and rather sweet taste. But it is on 4 in the ranking of Germany’s best selling beers so it can not only be ladies who buy this beer. It is actually better then it’s reputation and sold worldwide. I’ll give it a try more often, also because of the result of the gluten test:

                    Beer: Warsteiner Premium Verum
                    Producer: Warsteiner Brauerei Haus Cramer KG

                    Bottle size: 0.5 l = approx. 16 Oz.
                    Alcohol by volume: 4.8%
                    Ingredients: water, barley malt, hops extract
