Yeah I watched a few of the videos. My concern was how much it would run, because that coil is small, and how low it could keep a temperature consistently. If I can get it down to the low 50s to ferment then I can lager in a keg.
So were you only able to get the fermenter down to 47 degrees with the glycol with below 32 degree temperature? So what were you able to get the temperature down to steadily with ice water? Does the pump run constantly to keep the temperature? My concern is, I do not want to build a glychol...
