Duvel Gluten Test

There are not many Belgian beers available in Germany. Well, there is actually no need to import beer from Belgium as the German beer is generally good but Belgian beer has a good reputation in the world. From the few Belgian beers I found most contain strong alcohol and wheat like Chimay and Grimbergen. One exception is Duvel, no wheat according my internet research (see below the ingredients are not listed on the label) but still strong alcohol. Alcohol delivers flavour so Duvel has a crisp taste. But for me it has too much alcohol and too much gas so it will not become one of my favourites. And here is the gluten test result:

Beer: Duvel
Producer: Brouwerij Duvel Moortgat
Originating country: Belgium
Brewing location: Belgium
Bottle size: 330 ml = approx. 12 Oz.
Alcohol by volume: 8.5%
Ingredients: water, malt, yest, hops (internet research)
Miscellaneous: Ingredients not listed on label

Duvel Gluten Test Duvel 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.

Duvel 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. In this test there is no indication that Duvel has more than 5 ppm gluten. However, it is not a medical advice – please see my facts page.

    Brooklyn Lager Gluten Test

    I recently had the chance to drink a bottle of Brooklyn Lager, a very nice American beer which tastes completely different to the, well, typical American style beers. It was refreshing and crisp and not flat at all. And of course I wanted to see how much gluten it has. Moreover, it claims to have less than 5 ppm (please keep in mind the widely accepted gluten free level is 20 ppm):

    “None of our beers are gluten free. Unfortunately, we don’t routinely test for gluten content in our beers. We are only able to quantify up to 5 ppm of gluten and confirmed that Lager has less than 5 ppm of gluten. Unfortunately, our current production demands do not allow us to produce a gluten free beer.”

    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.

      Pilsner Urquell Gluten Test

      Pilsner Urquell is the surprising winner of the latest poll. Because of the popularity of the American Budweiser I thought the Czech Budweiser will clearly win the poll but the majority voted for Pilsner Urquell. This beer is also famous as it was the first Pilsner style brewed beer. Here is the gluten test result:

      Producer: Plzesky Prazdroj

        There are plenty of excellent beers available in Czech Republic. The best selling beer within the country is Gambrinus -the god of beer- which I already tested in 2013. The most famous beer of course is Budweiser due to the popularity of its American brother which only have the same name but nothing else in common. Pilsner Urquell is a famous Czech export beer whilst Staropramen is the favourite beer in the capital Prague. Please vote which of these Czech beers you want me to test next.

          Beck’s Gluten Test #2

          As with the recent Warsteiner validation test I also tested Beck’s a second time using a different test kit. In the first test I used the Imutest test kit which uses the antibody Skerritt. And here is the result with Biomedal’s kit which uses the G12 antibody.

            Dorada Gluten Test

            Dorada is a very nice beer from the Canary Islands which belong to Spain. The Canaries have a mild climate all year and so a cold Dorada is always an option even during Canarian winters. Mainly tourists from England, France, Germany, Netherlands and the Scandinavian countries visit the islands to enoy the sun. And for all those who are sensitive to gluten and plan to go there this test is for you.

            Beer: Dorada

              How to read the gluten test summary table

              The most visited page on my site is the test results summary table. As I received a few enquiries how the table works here a short explanation on how to read the test results.

              I test the beer with two different test kits which also work differently.

              The Imutest kit works with an intensity scale, the darker the test spot the more gluten is in the sample. The test spot intensity is scaled from 0 (no visible spot) to 20 (dark red) whilst the control spot is estimated with an intensity of 6/7 (light pink). This allows the estimation of the level of gluten based on assay from the manufacturer. In the example below the test spot was rarely visible (intensity of 1 or 2) and so the gluten level is very low, surely below 20 ppm and maybe even below 5 ppm.

              The Biomedal kit works with thresholds which can be set to 40, 20 or 5 ppm depending of the number of drops from the extraction solution which will be added to the unit. If a red test line appears the test is positive. In the example below the test with the 5 ppm threshold was negative so the beer has less than 5 ppm gluten.

                Warsteiner Gluten Test #2

                This is the second test of famous German beer Warsteiner. The first Warsteiner gluten test was negative and it actually became my favourite beer, also because of the test result. In the first test I used the Imutest test kit which uses the antibody Skerritt. To validate the result I wanted to see how Biomedal’s kit with the G12 antibody reacts. In a recent post I listed some test kits and information about antibodies and how they work. But to make it simple – the more tests are negative the safer it is for gluten-intolerant people.

                  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:

                  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.

                  -to measure the sample use the enclosed spoon
