Hello HomeBrewTalk! I'm new to home brew, getting ready to taste my first batch, bottle my second batch, transfer my third batch, and brew my fourth batch today. Big day!! I'm worried about the bottling though. The beer is a kolsch, the yeast is WLP029. It spent a week in the primary at 62 degrees and two weeks in the secondary. Of those two weeks in the secondary, the first 4-5 days were at about 60 degrees, and the remainder at about 50 degrees (on my garage floor). I moved it in last night so it could settle before moving to the bottling bucket and, to my surprise, there are clusters of CO2 bubbles covering about 60% of the surface, and the airlock is bubbling about 1 bubble every 40 seconds or so. I thought it might just be expansion as it warms back up again, but the bubbles on the surface suggest fermentation. I'm wondering if I cooled it down too soon, but from what I understand, Kolsch is usually done fermenting in 4-5 days. I let it go a week, and then another 4-5 days at fermentation temp. Should I be concerned? Should I avoid bottling for a couple days? Whattayall think?
