I do not know about the swirl method. It would seem the three layers are trub at the very bottom, old yeast in the middle and newly created yeast on top? This does not necessarily mean the old yeast is dead though.?
I was joking about the mason jar conical. Might be nice to have a micro conical for yeast ranching though.
