Today I tested one of my favourite beers – Gambrinus from Pilsen (Plzen), Czech Republic. Gambrinus is the best selling beer in Czech Republic but also sold in Germany. It offers excellent value and has a nice smooth taste.
Beer: Gambrinus Premium
Producer: Plzesky Prazdroj
Originating country: Czech Republic
Brewing location: Czech Republic
Bottle size: 0.5 l
Alcohol by volume: 5.0%
Ingredients: water, barley malt, hops (translated from German)
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 ). But the test spot is a bit darker.
Each test kit is a quality assay included which helps to interpret the result. There the intensity is scaled from 1 (barely visible) to 20 (dark red) whereas the control spot is estimated 6/7 (light pink). And as mentioned above this is the recommended level for very low gluten in the sample.
On a scale from 1 to 20 I would rate Gambrinus a 8/9 so it has a bit more than 100 ppm. Even though this test is positive please note it is not a medical advice – see my facts page.
