Perhaps, and maybe the SCOBY dies at worst, or maybe the brew becomes naturally acidic as the acetic acid is made

It doesn't look unhappy or unusual, seems natural and well suited to each other, but time will tell.

I've also unintentionally fermented ayahuasca in the manner of just letting it sit out, and it definitely changes a lot over weeks time, noticeably, it even appeared to develop a culture on top, and it develop a fermented smell that was very distinct and sort of nice, I didn't drink this though, I painted with it. Need to experiment more.
