Short story. I had mead bulk aging in a 1 gallon carboy and the solid bung popped out, I don’t know how long ago this happened, but today I discovered it. The fruit flies (about a dozen) were still floating. I smelled the mead and did not detect any vinegar aroma, removed the dead insects and covered the mouth of the carboy. The question I have is does the campdon I used when racking a few months ago continue to protect against bacteria? Should I just give it another treatment of campdon? Just drink it before it turns? What would those of you with more experience do in this situation? Thanks!
