Good to know. I wonder what his problem is then. I suppose it does not take a lot of yeast to carbonate, it might just take longer.
Without cold crashing I still manage to get most of the beer out, but probably not that last cup that you do. The trub hardness for me greatly depends on the yeast but with care I can get all except a small puddle by the spigot. The last bottle for me is a partial PET bottle tester anyway. I think I lose more beer in the hop bags than left in the LBK.
