This is a 4th generation WLP001 slurry I saved.
I transferred this cake to the container after vigorous swirling. The upper layer is odd to me. I have been getting it on the last several slurries i have transferred. It doesn't settle out and it smells like fresh yeast. When I scoop it off it is almost like a gelatinous raft and comes off pretty easy without breaking up (too much).
I saved the raft off of the last slurry and I think I'm gonna try to make a starter with it....just to see what happens.
What is it?
Should I scrape it off or swirl it in before I distribute to smaller containers?
