I followed the illustrated tutorial, and washed my WLP004 off of a stout.
At that time my jar showed a thin layer of beer on top, a light layer in the middle (yeast), and a slightly darker layer at the bottom (sediment)
After a night in the fridge it looks like this:
What am I looking at here? Is that entire layer on top supposed to beer that I need to remove? My other 2 jars have the same characteristics.
