I brewed a 10 gallon batch on Saturday. Pitched the Bry97 into both buckets.
5 days later, one bucket is bubbling away. The other…nothing.
Both are in tubs of water. The one bubbling away is in a larger tub and its about 3/4 deep on the water. The water temp in the deep tub is 65.5
The shallow tub only goes about 1/4 up the side of the fermenter. That water is 64.4 and zero bubbles in the airlock.
I cracked open the one with no activity and there is plenty of krausen in there, so I’m not too concerned.
It just seems weird that one would be bubbling away and the other doing nothing when both are the same beer and same yeast and only 1 degree temp difference.
