I usually try to transfer every last drop out of the brew kettle into the fermenter. I figure, it is all going to settle out. maybe even add a little more hop aroma? Might even be some coagulated sugars in that gunk.
So do you leave a thick layer behind in the brew kettle? Or do you tip it to get as much as possible?
Currently I just have a bulkhead in my kettle, without any pick up tube or mesh or anything.
I only use a hop bag if I am using leaf hops.
