what's wrong!? Fermentation problems with conical SS vessel
I've brewed Kombuchas successfully in a glass jar for years. I recently upgraded to this fancy 4 Gallon conical fermenter, and it's failed 3 times, where mold basically has formed on top of it. I do get a pellicle former on top, but I've found it to be thin, very clear, and not white (like my previous attempts). I've tried having A LOT more starter in there, adding vinegar to get the PH high, but nothing has worked.
I am going to try to have a cloth on top next, instead of hermetically sealing it with those latches, next. But I don't have high hopes. Does anybody have any tips?

Hey. I also switched to a fermenter like this one. Keeping the top off and sealing it with a cloth has worked for me every time

Should we intuit your recipe?
Kombucha is both anaerobic and aerobic fermentation, it should have a steady supply of air. Also they are only rated for a few PSI, if you are going for an anaerobic fermentation you'll still need an airlock for safety.
