Things have been slowing up over the past few days to the point where I’m just seeing a small burst from the airlock once every minute or so. The ring of foam around the top of this brew is also shrinking, and seems to be made up of larger bubbles instead of the tiny ones we’ve seen until now.

Weirdly enough Type 25c in the adjacent vessel has started bubbling again a few days ago, despite me doing nothing to rouse it from its dormant state.
