I brewed my first batch of beer ever (Caribou Slobber) using the Essential Brewing Kit. After adding the yeast, the airlock was bubbling like crazy for about two days, then there was silence. It has been 2 weeks, 3 days since brew day (the beer has not changed locations) and today I noticed that the airlock has started up again. The bubbling is not as frequent as it was originally, but it is definitely noticeable. I was waiting until this Sat. (the 3 week mark) to bottle after deciding to skip secondary fermentation. Is this a reactivation of the fermentation process and should I be concerned?
Thanks for your input!
