I'm making a Sierra Nevada clone kit. I broke the batch into halve and did one batch already a few months ago and am doing the second batch now.
The first time I used some Wyeast yeast that came with the kit. Now, the second time I'm using some Safale dry yeast.
Both times I notice that when I wake up in the morning around 8am or so that there is no bubbles in the airlock. I then shake the fermentor around making bubbles and within 30minutes the bubbles go again.
My initial thought was that the yeast use up most of the oxygen at night, then in the morning when I shake it, it wakes up.
Another thought is that the temperature change is messing up the yeast. During the daytime, it is 82F and at night I set it to 77F.
Does anyone have any thoughts on this? I've seen videos the recommend aerating initially but haven't seen any mentioned after this. I've been doing this every morning and sometimes throughout the day.
