After using my immersion chiller, both the hot and the cold break are in the kettle. I pulled out the chiller, and stirred up the wort for my whirlpool. I let it sit about 20 minutes. It's a brown ale this time, but the wort looked very clear before I started to rack. I pulled probably close to half a gallon before I put the tube in the carboy. It was still very sludgy into the carboy, but I didn't want to lose any more wort. Eventually, the siphon was running crystal clear. When I got near the bottom of the kettle, I could see that no cone had formed. Has anyone ever let the wort sit in the kettle for a long period of time before racking to the fermenter? How long could I let it sit in the kettle for the trub to settle, and siphon more clear wort? I really don't want to use any sort of a strainer just yet. What if I let the wort sit in the kettle for 4 or 5 hours? Does anyone do anything like that?
