After completing numerous home batches of beer and realizing that I did not have any control over my fermentation temperature, I decided to build a simple little device which I labeled the “Fermentation Temperature Control” (or FTC for short).
This device works great for those want to ferment inside a refrigerator or freezer and have digital control over the process. The device pictured is installed on the side of a freezer.
The device consists of an electrical box, an outlet, and a LOVE brand temperature control. The LOVE control comes with a temperature sensor which I place inside the carboy by way of a stainless thermowell. You could also place the temperature probe (in a thermowell) inside a glass of water which is stored inside the freezer or refrigerator. Ambient air readings are not as accurate using the Love style temperature sensor.
The freezer or refrigerator is set to its coldest setting. The Refrigerator or freezer is plugged into the Fermentation Temperature Control outlet. That’s all there is to it. Set the Love Control to the appropriate temperatures and watch your fermentation temperatures hold steady!
