Getting very excited to see all this happen in front of me and looks like a real real dark beer, nearly black
(due to kits being old and doubling up).
One question I have is how do I know when its time for secondary?
And what is that dark brown stuff in the foam?
Maybe as well how do I harvest yeast?
Will update y'all tomorrow
Thanks guys and happy brewing!
The darker brown ripples in the foam isn't anything to worry about. I think it's just dry edges when the light bubbles break.
I would skip the secondary unless you plan on a long term bulk aging, it's just another chance of infection or oxidation.
Google yeast washing, there are a few threads that walk you through the process with lots of pictures.
