This is my second time doing 5 gallons of wild-fermented cider. Last year I had no problems. After two or three weeks at room temperature, it bubbled vigorously just as I had hoped. This year, nothing. No bubbling or anything. I have been stirring it everyday two or three times, but it has been two months and nothing has happened. Is there anything I can do to save or restart my cider at this point? Or does it need to be dumped out? Any ideas on what went wrong?
