Tasting fpj

I am brand new at fermenting. I recently attempted making fpj and I believe everything went well. My question is when I taste the fpj it makes my body feel as though I just took a multivitamin, or maybe a very low microdose of mushrooms. I've been taking a couple drops a day and I feel amazing!! Is this all placebo or is my body just craving all the microbes and I actually am feeling a uplifted and maybe slightly tingly? Or did I brew up some bad stuff and that's my body fighting it lolol

The answer

From the KNF library

From the KNF library Drafted by Claude from Office Hours and the books · Sep 2026 · 4 sources

A first-time maker asked Drake nearly the same thing after a wildflower batch gave them an unusually great mood. (Office Hours Ep. 10, 11:37) Drake's answer: microbes from the plant's surface break the juice down, so it is more bioavailable than fresh juice. (Office Hours Ep. 10, 11:37)

Drake also describes FPJ as potentially broccoli in a pill. That sits close to your multivitamin comparison. (Pure KNF Manual, p. 38)

To check for bad stuff, look at the jar. Drake says white wispy mold is fine and usually yeast. Avoid red or black mold, and pour off the liquid, not the top layer. (Office Hours Ep. 132, 42:16) If the batch sat too long, it keeps breaking down through secondary fermentation. Drake's fix is to pour it off and pack it with sugar to stop the process. (Office Hours Ep. 57, 28:14)

The library does not say whether your feeling is placebo, or how many drops are safe to take.

well. did you know that the original Korean word for what we call "FPJ" is "Green Juice From Heaven"? not kidding. some o.g. knf trivia... My second thought, after "divine microbial medicine" was sometimes sugar makes me feel high...and that green juice can sometimes turn alcoholic if it over ferments in the first stage. but this may not be the case at all. truly, i would have to agree with you (to a degree). I feel great when I drink fpj too (especially diluted in water with a slash of vinegar and LAB.) i once gave a girlfriend of mine some fresh LAB whey and she said after the first sip she felt a rushing feeling of energy and happiness. i think she reeeeaaally needed the microbes and her body knew right away it was a good thing.
