I'm not sure but I have become, a minimalist, a germ a phobe or just lazy.I ferment 3-4 weeks (sometimes longer), I no longer use a secondary. Cold crash @ 34-36 degrees for 5-7 days, heat 2 cups of water to 190 degrees mix one pack of gelatin, let cool, pore in keg and rack beer on top. The first pint or two off the keg may be a bit cloudy from the particulate the the gelatin adhered to. But by the third pint it is crystal clear.
