I have had a 5 gal batch of graf (cider-beer) going for a few weeks. I had it in primary for 8 days and then racked to secondary for what will be 8 days tomorrow. I was supposed to bottle after 14 days but last night when I went to bottle I noticed that my airlock has restarted. I took a SG reading (Started at OG 1.062) and it read 1.010. This afternoon about 12-15 hours later I took another reading, still 1.010, but the airlock is still active. There is no sign of contamination. I decided to rack the brew from secondary into my bottling bucket (minus priming sugar of course) in hopes to remove a possible bed of active yeast. It has slowed down but is still bubbling. I will note (before I get the question) that the house has gotten a little warmer in the past couple of days. Any ideas? Should I be waiting to bottle? How long? Could this just be dissolved CO2 being released?
