Good morning ladies and gentlemen, I am in the process of making my first spirit/wood aged beer, a bourbon barrel porter. I don't have a barrel so I used 2oz. of American medium toast oak cubes that were soaked in 16oz of Makers Mark bourbon for 2 weeks. Last weekend I transferred it to secondary where I added the bourbon and oak cubes. My OG was 1.065 and my TG was 1.010. I was planning on bottling it next weekend until I made a discovery this morning; it seems to have gotten going again. There is a nice krausen foam across about 1/4 of the surface and I can see the tiny bubbles rising from the bottom of the carboy after it sat dormant for almost a week. Kind of a multi-part question here: What could have caused it to seemingly kick up again? Is there any harm to leaving the cubes sit in the carboy more than two weeks? Would it still be safe to bottle next weekend and assume any activity I'm seeing is negligible? Thanks and cheers!
