| | I don't stir as it chills. I swing the chiller back and forth in the wort. I | have the tubing (in and outs) at the right height, so the tubing rests on | the rim of my brew put and the bottom of the chiller is just off the bottom | of the brew pot. So it is east to swing it back and forth, which keeps the | wort moving and chills it down faster. | | -- | | I Brew My Own Damn Beer! | Johnny Mc | | To E-mail me, get rid of the "BAD-BEER" | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
I used to stir before I got my pump......Now I just start the pump and recirculate when I add the chiller at 15 minutes to flameout.........So nice......HJ
