This low energy RAPT enabled Bluetooth Thermometer is compatible with the Gen 4 BrewZillas and RAPT Temperature Controllers and RAPT Fermentation Chambers. It will not work without one or more of these devices.

By receiving multiple BLE thermometer sensors the BrewZilla can make smarter and more automated decisions on how to control the brewing or distillilation process.  For example a BLE thermometer can be placed into your coolant water so you get an alarm if the temperature is too high, a BLE thermometer can be put into the middle of the malt pipe so you can more accurately control elements switching on/off to achieve a core malt pipe temperature etc.

WLP685 Gluconobacter oxydans is a gram-negative rod bacterium belonging to the family Acetobacteraceae. This aerobic organism is common in fermented beverages like kombucha and kefir. Gluconobacter oxidizes ethanol into acids such as acetic acid and gluconic acid. Optimal growth between 25-30C but is also known to be a very slow grower. It will more slowly oxidize ethanol at 20C.

Silicon bung with hole for airlock. Tapered - 20mm-35mm. Suitable stopper for most carboys and flasks.

This 30w Heating belt will gently warm without creating major hot spots on your fermenter. 
One reason to go belts over pads for the simplicity of adjusting the height of the belt on your fermenter to increase or decrease the heat transfer. With a pad, you're unable to do this, and may potentially cook your yeast turning your hard work into a giant bandaid.

We highly recommend using a belt with a temperature controller for precise temperature control. If you're fermenting in a fridge, you can also use the controller's cooling function as well to control both the belt and the fridge.

This temperature connects with the RAPT web portal meaning that you can monitor, log and control the devices plugged into this temperature controller box remotely.

A Heat Pad to help keep your home brew warm. Also called a heat panel. 


This is a quality, New Zealand made product.

Control your fermentation temperature accurately, every time!
