The D+caf Test Strip is a unique new product that quickly and easily determines whether your coffee or tea is really decaf. The process is quick and simple to use, with lab accurate results. Simply contact the test strip to the beverage sample for five seconds and view the results within 30 seconds. The makers, Silver Lake Research, claim that this test strip is the first and only test that is fast, accurate, easy-to-use and cost effective.

The coffee (or tea) soaks into the paper of the test strip and antibodies in the strip react with the fluid darkening a red line either towards a ‘D’ (for decaf, or less than 20mg of caffeine) or a ‘C’ (for caffeinated, 20mg or more of caffeine). A useful item for those who prefer decaf or lower caffeine contents in their drinks – and want to ensure that what they order is what they are being served!
