Over supersaturated FPJ
Hi, what happen if you over supersaturated your FPJ? Is it still good or make a new one? Thanks
Top answer
Yeah it’s good to use. It won’t hurt anything. You just have a bit of sugar at the bottom of your solution now.

The settled sugar layer is not usable as plant juice, per Drake. (Office Hours Ep. 133, 1:04:40) Scrape it out and bake cookies with it. The hormones, enzymes, and endophytes have already dropped out. (Office Hours Ep. 133, 1:04:40) That differs from the reply above, which says it hurts nothing.
Adding sugar to the point of supersaturation is the plan. The Pure KNF Manual says to let fermentation happen once, then saturate the liquid with sugar to stop it. (Pure KNF Manual, p. 38) For long-term storage, the library says to combine the FPJ with equal parts brown sugar. (Student's Manual, Basic Course, p. 36)
The library does not say whether the liquid above the sugar is still worth using, or when to start a new batch.
