Control your fermentation temperature accurately every time!
Temperature control is one of the most crucial elements for producing a good quality beer. It needs to be regulated and stable throughout the whole fermentation process to ensure the yeast doesn’t get stressed and ferments correctly to get the right flavour profile.

With the ability to individually power and control the temperature of up to four Grainfather Conical Fermenters, each with their own fermenting schedules, the Grainfather Glycol Chiller is the perfect addition to ensure craft brewery-like results.

With the addition of the Glycol Chiller, your system is operating at the ultimate level and you are even able to cold crash and lager. The cooling sleeve is located in between the two stainless steel walls of the Conical Fermenter which is then hooked up to the Glycol Chiller. Temperature is dialed into the digital temperature controller and the liquid travels through this sleeve, cooling the stainless steel which in turn cools the beer in the fermenter. The cooling sleeve never comes into contact with the beer, is completely concealed and does not need cleaning or sanitising – a true innovation for a fermenter on this scale.


Allows you to cold crash 23 L of wort to as low as 4-6ºC. Minimum temperature will vary based on external factors such as ambient room temperature, the number of fermenters connected and other environmental conditions.

Cools and powers up to 2 Conical Fermenters at different temperatures and fermenting schedules.

    This unit has been a bit of a game changer for me. The units are a significant cost, so I spent quite a bit of time thinking about it before taking the plunge.

    My GC2 is connected to two GF30s. I use it to control the temperature accurately during fermentation and then cold crashing it at the end of the cycle. As I am unlikely to increase the number of GF30s that I am using, the GC2 was a perfect fit, i.e. no need to purchase the more expensive GC4 unit. It controls the temperature of the fermenters perfectly and it is great that this is done independently. Also the fact that the fermenters get their power from the GC2 means that I can do away with the transformer units which makes my overall setup simpler.

    My GF30s have had about 150 brews through them between the two. I used to use a manual chiller to control the temperature, but this was always a bit “hit and miss” as sometimes I would forget I had turned the chiller on! The end result of using this method was that the fermentation temperature was often +/- 2-3C and varied throughout the fermentation. I have used the GC2 unit three times so far and the results have been absolutely spot on. The temperature is always kept +/- 0.2C throughout and I can get the fermenters down to around 5C at the end of the cycle. Since I can now reliably ferment at 12-15C, I now have the option to brew cold IPA and lagers.

    The GC2 unit has enabled me to accurately control another one of the variables in the brewing process and do so with a lot of precision. The end result is that the beer has improved significantly. For me, it was a great decision to purchase one of these units!
