I made my first batch of hard cider this fall. I fermented it for 3 weeks, then I transferred the cider to a carboy about a week and a half ago and it is no longer showing any signs of fermentation in the airlock as of today. I am wondering what to do with it as of now if it just means that I could get ready to keg it or if it can still sit with the airlock in. I'm just hoping that something has not gone wrong.
