You have voted for Heineken in the recent poll. After I tested Heineken already on a 40 ppm threshold a while ago here is the test result with a more useful 5 ppm threshold. And because of the result I tested Heineken a third time – on 20 ppm. Please see below what happened and my conclusion.
Producer: Heineken Brouwerijen
Originating country: Netherlands
Brewing location: Netherlands
Bottle size: 0.4 l
Alcohol by volume: 5.0%
Ingredients: water, barley malt, hops extract (translated from German)
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.
Test result: A barely visible red line appears on the right of the test stick ( T ). The red line is quite weak however, it indicates the presence of gluten equal to or above 5 ppm. 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 positive please note it is not a medical advice – see my facts page.
From my first Heineken test in 2013 we already know that the level is below 40 ppm. The second test now shows that the 5 ppm threshold has just breached. So we are getting closer to a result but we are still not there. Hence I tested again and this time on the 20 ppm threshold.
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. Again please don’t take any of my test results as a medical advice – please see my facts page.
Conclusion: The gluten level in Heineken is somewhere between 5 and 20 ppm. Because of the very weak red test line after the 5 ppm test I would say that Heineken is closer to 5 than to 20 ppm.
Test on 40 ppm = negative
Test on 20 ppm = negative
Test on 5 ppm = positive
Please note the different picture colours are due to the fact I wanted to visualize the test results better and used image editing software. As explained the red line on the 5 ppm test was barely visible but it was there. But on the original picture (taken with my smartphone camera) it was not really visible, hence I used the software to enhance the picture quality.
