I brewed a NB Partial Mash Oatmeal Stout 5 weeks ago. It has had slow but steady fermentation since the beginning. After about 2.5 weeks at low to mid 60’s, I moved it to room temps to finish up. It never really did. Still lots of foam on the top and fairly slow airlock activity. Along with two other brews, I transferred to secondary on Friday night while brewing other batches. Yesterday, the other two were as I usually see them, no activty, just clearing.
But the Stout had a pretty nice layer of foam and somewhat steady airlock activity.
OC was about 1.051 and when I transferred to secondary it was 1.010. Should I let it keep going? Sample I tried was excellent and was the first time I think I fully understood “mouth feel” Really smooth.
How low should I let this go?
