No it's a real thing.
You make a tincture from propolis and 80-90% proof alcohol that dissolves the propolis, filter then stir it into the honey.
Some beekeeping suppliers have a ready solution ready for mixing.
Mixing alcohol/ whiskey into honey takes time and the honey only can take a mix of 1-2% of alcohol to 98-99% honey.
It tastes a bit like cough medicine, I have tried a jar from a beekeeping friend and its perfectly fine
The propolis tincture is made with tasteless grain alcohol
