Atelier der Braukünste in Germany has made, not just a COVID test beer, but a COVID test series, called Test-Trace-Isolate.
“By rubbing the cross, a smell of Christmas will appear,” the label advises–and then, if you can’t smell the hops, the label steers you to an exceedingly thorough questionnaire to see if you should be tested for COVID.
Mind you, the concept is very tongue-in-cheek. But the information the label provides is frankly invaluable. And the questionnaire is certainly much more thorough than the ones in use where I live.
