I've got a batch of fermented hot sauce on the go which is about two weeks old. It's started forming Kahm yeast, which is a really bummer as the plan was to ferment this batch for four to six months. I've removed the Kahm yeast with a ChemSan'ed spoon once already, but it grew back within a couple of days. So today, I did a brine flush by filling up the fermenting jar with fresh brine until what ever Kahm yeast particles I could see, were flushed out of the jar. I then left less headroom in the jar, wiped the inner surface with ChemSan, and sprayed the outer jar with it too, just to be safe. I've also put stronger brine into the airlock, not that I think it'll make much of a difference.
My question is, (1.) where do I proceed from here? I really wanted to ferment this batch for longer but I don't want the Kahm yeast to ruin the batch. (2.) Should I just carry on cleaning out the Kahm yeast and ferment for as long as I want or should I reduce the amount of time I ferment the batch for?* (3.) The batch in question is in close proximity to other batches of hot sauce. They're all airlocked and are currently showing no signs of yeast growth but (4.) should I move the yeasty batch away somewhere else to prevent cross-contamination?
*I tested the pH of the brine and it's already at 3.8, so I guess it's technically ready to bottle... I just want more funky flavour though!
