I cut about an inch off the dip tube. I cold crash, then fine the primary with gelatin at least 24 hours before I transfer. When I transfer, I rack off about two pints through a picnic tap (it runs clear during the second pint before I put on my jumper to transfer to the two serving kegs. There's still a little junk in the bottom of the serving kegs, but any residual gelatin clears then pretty quickly.
I need to research more into fining with Gelatin .... we can buy Kosher, Organic beef gelatin online, is the same kind of gelatin that we would need for fining?
