I have an IPA I brewed and let sit in the primary for 3 weeks. I took gravity readings and fermented all the way down to 1.010 from 1.062. Everything went great and the sample I took tasted great. I moved it to secondary and let it sit for a week, then dry hopped 5 days ago. After adding the hops I appear to have activity in the air lock again and even the beer appears to have activity in it (I can see the hop particles swirling) like it's fermenting again. Has anyone seen something like this? I dry hop all the time and haven't seen this before! I was hoping to bottle but I'm afraid to create bottle bombs if there is some kind of activity but I wont have that fresh hop aroma/taste I was going for if I wait much longer. I'm going to take a new gravity reading tonight to see if that has changed as well. Any suggestions? Does anyone know what could cause this and if I should wait to bottle? Thanks!
