I started a cider on 12-12-12, I didn't rack it to a secondy vessel until 1/6. I noticed it still had a lot of carb, so I left the airlock on instead of capping it. More than a week later, I still see bubbles. I haven't measured the final gravity. But I know it's done. The cider is dry and definitely has alcohol in it, so I don't think I have a slow or stuck fermentation on my hands. Why is it taking so long to degass?
