November 2014 – Low Gluten in Beer

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 Gluten-in-Food 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.

The GlutenTox Home 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 based on the defined threshold.

This is how it looks like on desktop PC’s:

On smartphones and other responsive devices it looks like this:

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.

Beer: Warsteiner Premium Verum

Originating country: Germany
Brewing location: Germany
Bottle size: 0.5 l = approx. 16 Oz.
Alcohol by volume: 4.8%

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: 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 Warsteiner has more than 5 ppm gluten. However, it is not a medical advice – please see my facts page.
