According to my Ukrainian co-worker, back in 90s Kombucha was known as a horrible traditional delicacy similar to surströmming, hákarl or casu marzu.

And yes, I have had a co-worker who drank weird smelly herbal teas and was obsessed with vitamins among other things. And a different one who had a mug that was covered with thick black crust inside and who insisted that it must never be washed.
