Save the Day IPA Gluten Test

This is a test from Tadd, the owner of Blast Beer Company based in Florida. His beer is a Low Gluten American IPA and he uses prolyl endopeptidase (PEP) to reduce the gluten content. It’s the first time we have a beer tested with GlutenTox Pro. It uses the same antibody (G12) as GlutenTox Home.

Beer: Save the Day IPA
Producer: Blast Beer Company, Key West, Florida, USA
Originating country: USA
Brewing location: Orlando, USA
Bottle size: 12 oz. = 355 ml
Alcohol by volume: 6.9%
Ingredients: American 2 row, Citra hops, Cryo dry-hopped
Miscellaneous: Blasted to remove gluten! With PEP, prolyl endopeptidase, which is sold commercially as Brewer’s Clarex

Save the Day IPA Gluten Test

Test Kit: GlutenTox Pro

Test result: The beer contains less than 15 ppm according to the test report. As the test is a pass-fail style test the exact number is unknown. The test report falsely lists Blast Man IPA as the tested beer as explained by Tadd. In the Test Results table I will mark this test negative on the 20 ppm threshold as the test strip indicates a negative result (see picture in the test report). The name of the brewery manager who performed the test is blurred for privacy reasons. As usual please don’t take any test result as a medical advice – please see also my facts page.

In addition to this test Tadd also had the beer tested by ELISA Tech. They use the competetive test method with antibody R5 to detect gliadin. According to the assay gliadin was not detected in the sample which is considered below 5 ppm by the analyst. Unfortuntately it is not allowed to share a copy of the test result without permission.

San Miguel Light Gluten Test

I made a trip to the Philippines in February this year just before the COVID-19 lockdown. San Miguel Pilsner is the most famous beer in the Philippines and sold Asia-wide. The history of San Miguel is interesting as I always thought San Mig in Manila is a subsidary of the Spanish San Miguel brewery. But it was first invented in the Philippines and then the rights to sell it under the same brand name in Europe were given to a Spanish company.

I tested the Spanish regular Pilsner (San Miguel Especial) back in 2017 but when I saw the light version in the Philippines I wanted to give it a try. This light version is not available in Europe or the US as far as I know. The Spanish San Miguel brewery also don’t have this one in their product portfolio. But I recently learned they have an officially labelled gluten-free beer which I will try when I get my hands around it.

Coming back to the San Mig Light. The taste is good, in the heat of the Philippines absolutely the right one to get refreshed. Of course enjoy it chilled. Gluten was also not detectable in my test, see below.

Beer: San Mig Light
Producer: San Miguel Brewery
Originating country: Philippines
Brewing location:Philippines
Bottle size: 0.33 l can
Alcohol by volume: 5.0%
Ingredients: water, malt, cerals/sugar, 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 test is negative please note this is not a medical advice – please see also my facts page.

Perlenbacher Pils Gluten Test

I had a request from Northern Ireland on a German beer which I didn’t know until then. It’s the Perlenbacher beer from the German discounter Lidl who is present all over the world I guess.

In German Lidl stores two variants of the Perlenbacher are available – one with 4.9 ABV and one with 5.2 (considered the “Export”). I tried both and couldn’t taste any difference, though. The Pils comes in a nice bottle with twist cap which is very unusual for Germany. Almost all the mainstream beers in Germany come with crown cork or flip-top. The Perlenbacher Export comes in a plastic bottle which is an insult to every beer lover.

For the gluten test I used the 4.9 ABV Pils. It is hoppy, bitter and has good carbonation. It tastes more like a typical Northern German bitter beer. It was OK to drink but not very quaffable. And here is the result of the gluten test.

Beer: Perlenbacher Pilsner
Producer: Frankfurter Brauhaus
Originating country: Germany
Brewing location: Germany
Bottle size: 500 ml
Alcohol by volume: 4.9%
Ingredients: Water, barley malt, hops
Miscellaneous: German beer which is using twist cap

Perlenbacher Gluten Test Perlenbacher Gluten Test

Test Kit: Imutest Gluten-in-Food Kit

Test result: There is a very faint but visbile 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 ). As this spot is very faint the gluten level seems to be much below 20 ppm.

Perlenbacher 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 the Skerritt antibody they used earlier, hence I will mark the test just positive. Please find some more information here. Even though this test is positive please note it is not a medical advice – see my facts page.

Tuborg Pilsener Gluten Test

There was a very clear result on the latest beer poll. Well, it strangly jumped on one day from a very close result to a huge lead and at the end to a clear winner. It seems “somebody” was really interested in getting this beer tested and voted over and over for Tuborg. Anyway – a poll is a poll and even without this “somebody” it was not unlikely that Tuborg wins this poll. 

I tested the German variant of the Tuborg pilsner and I don’t know if this is similar to the “Tuborg Green”. If you know please use the comments to let us know. 

And here is the test result:

Beer: Tuborg Pilsener
Producer: Carlsberg
Originating country: Denmark
Brewing location: Germany
Bottle size: 500 ml
Alcohol by volume: 4.9%
Ingredients: Water, barley malt, hops
Miscellaneous: on the label stated that the beer was brewed in Germany in accordance with the German purity law

Karhu 5,3 & Lapin Kulta Gluten Test

Here comes a Finnish double feature for you. A Finnish friend of mine brought some beer and as I never had Finnish beer before I decided to test them. It’s Karhu 5,3 and Lapin Kulta – the latter is probably the most popular beer in Finland.

According to my internet research Finland has the highest prevalance of diagnosed CD in the world. So people are probably very much interested in the test results. 

For the taste I liked Karhu 5,3 more. Malty with a nice bitterness, still watery though. The Lapin Kulta was rather sweet and watery as well. Both didn’t cause any reaction to me. As usual please don’t take the results as a medical advice.

Beer: Karhu 5,3
Producer: Sinebrychoff 
Originating country: Finland
Brewing location: Finland
Bottle size: 0.33 l can
Alcohol by volume: 5.3%
Ingredients: water, barley malt, barley, hops

European Beer Poll

After I received a new test kit I will continue testing some beers now. As I mentioned in the 100 Gluten Test post I will not push anymore to post the test results quickly and it can be that I don’t post anything for quite a while. Anyway, here is a poll on some beers from Europe where you can vote for your favourite to be tested. So which European beer do you want me to test next?

Gösser (Export) – from Austria

New Test Kits Arrived

New kits have just arrived and I am going to do some tests soon. I will start with a poll and in parallel test some other beers. I was a bit sceptical since Imutest moved to the R5 antibody and changed some procedures. Still I am not convinced that it is the right way, hence I will use the new kits to verify the reliability. R5 is a newer antibody compared to Skerritt (which was used before by Imutest) and recognises the gliadin component of gluten. Is it the best antibody for barley containing products like beer? I don’t know to be honest. Anyway, tests are coming soon – stay tuned.

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:
