I only ever used Star San to sterilize when using bleach what ratio should I use? My only plastic parts are the auto syphon and my airlocks I intend on replacing them.
I recently got this infection in a batch of pale ale that I had fermenting now it has happened to a second batch. I did some research on here and it appears to be a lacto/pedio infection, can someone please tell me what could be causing this and what I can do to prevent it in the future.
