Landlord.
I made a starter as is my normal practice and sufficient to overbuild by 150Bn cells.
This was using WLP002 which is a very flocculent yeast.
As normal I placed on the stirrer plate, fermentation started as normal. At 18 hours I turned off the plate at high krausen. At 48 hours I planned to split the overbuild off into a jar and then stick both in the fridge until I pitch, so far all my normal practice.
However there was still a small amount of foam on the top and I was a concerned perhaps it had not finished, I remove the stirrer bar and put the erlenmayer jar to one side and then noticed many small bubbles rising, this lifted a chunk of yeast off the bottom.
30 mins later and a new krausen has formed and there is a lot of activity in the jar again?
I have never experienced this before, do you think this is normal or do you think I may have an infection?
