Keep your fermentation temperature in check with the BrewBuilt CoolStix for Speidel 30L Fermenter! Temperature control is one the most important aspects of a healthy, happy fermentation. When your fermenting beer gets too hot, the yeast will likely impart off-flavors that can easily overwhelm the taste of your finished beer. The CoolStix is a revolutionary cooling solution for homebrew fermentations. It is easy to clean, easy to setup, and cools quickly and efficiently.

You will also need a cold water source to provide the cooling solution. For maintaining ale temperatures, a cooler or bucket of ice water is sufficient in most cases. For maintaining lager temperatures, we recommend the Icemaster 100 Glycol Chiller.

We include a Speidel replacement spigot (FE785) so you can use the orange locking nut to install the CoolStix.

Will this work with the 20L Speidel Plastic Fermenter?
Ronald Nie on Sep 12, 2020
BEST ANSWER: Yes this is just short enough to offer 1/2" clearance from the bottom of the fermenter.
Can this be used with a Speidel 55 Liter or 100 Liter container? Due to the length of the cooling tube and thermowell I am concerned that they will not protrude sufficiently into the juice within the container to provide proper cooling or temperature reading. If not, what alternative might be suggested for these size of Speidal containers?
Ken Stafford on Jul 24, 2020
BEST ANSWER: Ken. The coolstix I bought fits the 30L Speidel well. I do not think it would work efficiently on anything larger. However, I did notice today that Speidel has introduced a cooling Coil, which could possibly be stretched to fit your fermenter. Good luck and happy brewing.
Can the blow off rubber gasket be purchased separately?

BEST ANSWER: Yes, I believe the part you're looking for is the Airlock Grommet #FE349.

Since the thermowell is so close to the water pipe, isn't there a high likelihood for false temperature readings?
Chris Stackhouse on Oct 8, 2019
BEST ANSWER: Hi Chris - We have found that during active fermentation that there is enough motion that the reading is accurate.
