…with the Indonesian beer, Bintang Pilsener.  It’s a 330mL bottle, 4.7% alcohol.  Ingredients: water, malts, sucrose, barley, and hops.  I find it strange that both “malts” and “sucrose” are listed before “barley”.  Perhaps the “malts” are from wheat.  That would make sense of the test result.  On an amusing note, my eldest step-son didn’t want to drink the beer so I used as a shampoo!

Bintang Gluten Test Bintang Gluten Test

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: A red line appears on the right of the test stick ( T ). The red line  indicates the presence of gluten equal to or above 20 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.
