Posting here because it feels like a beginner question. I have brewed off and on for quite a while starting with beer and messing around with meads, kombucha and even sake. I’ve had good and much-less-good brews along the way. My last few brews have been infected by the end of conditioning. Strong sour - acetone smell and this garbage at the top (see picture) which typically partially falls to the bottom when disturbed (taps or light shakes). Even before these I was fighting a “home-brew” taste that I suspected was the beginning of an infection. I tried saving a small batch mead with sanitizers and time to no avail. I’m tempted to try boiling this batch to see what happens but know it will probably make things worse and won’t really be beer after. I clean my gear after and before use, I use Star San prior to use and intermediate times in the process. I’m about to throw away all my gear, I assume the infection is somewhere in my gear. I guess I’m just posting this in case there are other ideas before throw it all out. Recently my beers have all been extract due to time.
