I brewed 2 Morgan's India Pale Ale. Put them in the primary fermenters on January 8. Although the instructions say to rack them in the carboys after 4 or 5 days, I waited until January 15. In the carboys, it seems like they started brewing anew even through the air locks. It finally settled down after 4 or 5 days. On the 24th, I was ready to bottle so moved the carboys on the table and the bubbles started although not for long. After a few hours, I went down and gave a little push to the carboys and again bubbles. I have never encountered this before except in the previous 2 batches which were also the same brand and type. Any ideas?
