Back in 2015 I started a poll about Dutch beer you want me to test and the winner was Heineken. On 2nd place was Grolsch – another famous Dutch beer and in my eyes the better tasting one. Adam was so kind to test Grolsch now. And here is the result.

Beer: Grolsch
Producer: Koninklijke Grolsch N.V.
Originating country: Netherlands
Brewing location: Netherlands
Bottle size: 450 ml
Alcohol by volume: 5.0%
Ingredients: water, malted barley, hops
Miscellaneous: –

Test Kit: GlutenTox Home Kit

Adam tested with a threshold of 20 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 20 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. Even though this test is negative please note it is not a medical advice – see my facts page.

Radeberger is not the best selling but probably the most popular beer in Germany. I found this survey which is almost 5 years old but things haven’t changed since then a lot I guess. Only mainstream beers were considered but Germany has so much beer and so many breweries. Look at this fantastic map which shows all German breweries (be patient it takes a while to load all pins).

Anyway, I like Radeberger and it is available almost everywhere in Germany.

Beer: Radeberger
Producer: Radeberger Exportbierbrauerei
Originating country: Germany
Brewing location: Germany
Bottle size: 0.5 l
Alcohol by volume: 4.8%
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 test is negative please note this is not a medical advice – please see also my facts page.

And here the story from Adam about his new favourite place:

I had been in phone contact with a brewer/owner (Alistair Turnbull) in the Adelaide Hills at Lobethal Bierhaus – https://www.bierhaus.com.au/

He had been very interested in what I had said about low gluten beers and the GlutenTox Home Kit. He also was telling me about a gluten free beer he had been working on with help from the University Of Adelaide, made from sorghum and lentils.

During my last trip to Detroit I wanted to try some local beer – Michigan beer. The most famous local beer seems to be Badass – the beer launched by Kid Rock. It is available in many locations. I have only seen this from tap and found it quite OK. Next time I will try to get a bottle to test it on gluten.

I was surprised how far Michigan is with gluten free options. In Clarkston in the outskirts of Detroit I was able to get gluten free food without problems. E.g. at the  Clarkston Union restaurant I was able to get my burger with gluten free buns. The Woodshop next door even offers gf Mac & Cheese – both of course serve Badass beer.

I had not much time to look for Badass in shops so the only local beer I found was Petoskey Sparkle American Lager and Rochester Mills Pine Knob Pilsner. I decided for Petoskey as I didn’t want a Pilsner but only found out later that it contains wheat which is according to my experience always a bad sign for the gluten concentration.

Beer: Petoskey Sparkle
Producer: Petoskey Brewing Company
Originating country: USA
Brewing location: USA
Bottle size: 1 Pint can
Alcohol by volume: 4.1%
Ingredients: not stated, back side lists wheat and 4 malts and 3 different types of hops

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.

On a scale from 1 to 20 I would rate the test spot intensity 2/3. 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.

Test provided by Joe from California:

I think it’s more of a quality Mexican beer with a crisp taste. It’s not my favorite but it’s definitely on of my top 5.

As announced in my previous post this is the first test of Greek beer. Not much to say about this beer, average taste, easy to drink but not really my thing. But the purpose of this site is to test the gluten level and here you go:

Beer: Mythos
Producer: Mythos Brewery
Originating country: Greece
Brewing location: Greece
Bottle size: 0.33 l
Alcohol by volume: 5.0%
Ingredients: water, barley malt, hops, yeast (internet research as ingredients are listed in Greek on the bottle)

I spent my last holiday on the island of Crete. Crete is the biggest of the Greek islands and fifth largest in the Mediterranean Sea. As usual I take the chance to test some local beers. But Greece is very much influenced by Dutch breweries. You get Heineken, Amstel and other Dutch brands easily and also some local brands like Alfa are owned by Heineken. So I decided to first test Amstel as I was currious but don’t worry I also tested a Greek beer called Mythos and will post the result soon.

In my hotel a cheap mass-produced beer called ‘Cretan Beer’ was served which tasted horrible. The barrel though was labelled with ‘Heineken’ so it seems the god and the rubbish beer is produced in the same brewery and all its somehow Dutch. But the bottled Amstel tasted quite OK – crisp and refreshing, good carbonation.

Beer: Amstel
Producer: Amstel Brouwerij/Heineken
Originating country: Netherlands
Brewing location: Greece
Bottle size: 0.33 l
Alcohol by volume: 5.0%
Ingredients: water, barley malt, hops (internet research as ingredients are listed in Greek on the bottle)

Zwickelbier or Kellerbier is a special type of beer which is unfiltered/naturally cloudy and not pasteurised. The term Zwickl or Zwickel comes from the sample of the beer the brewmaster was taken from the barrel with a special tap in earlier times. Zwicklbier is refreshing, less bitter and very quaffable. It’s a seasonal beer and best enjoyed in summer fresh from the barrel in a German Biergarten.

As the beer is not filtered I assumed already that it could contain higher gluten concentration than filtered beers and yes the gluten test was positive. Low positive but still positive. Although the beer was quite  nice.

Beer: Hofbrau Sommerzwickl
Producer: Hofbrau Munich
Originating country: Germany
Brewing location: Germany
Bottle size: 0.5 l

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 is quite faint.

On a scale from 1 to 20 I would rate the test spot intensity 1/2 so in this test the level is below 20 ppm. Even though this test is positive please note it is not a medical advice – see my facts page.
