I just saw a picture of Kai's trub cone and I thought "Why not me"? Time and again I am left with a thick layer of silt-like material spread across the bottom of my pot. I always have a fair amount of hot break, I use supermoss in the last 10 minutes of my boil and I chill rapidly with an IC. I then give it a minute of stirring around the edge of the pot and let it sit for ten minutes. Without fail I have no cone. I am thinking my problem may be that I use a ten gallon tamale pot which has a substantial indentation about two inches above the bottom. Perhaps it is messing with my whirlpool. Thoughts?
