Fermenting and Lagering Tips
In addition to our Construction Guide and A/C Selection Guide, here are best practices for brewing with CoolBot Pro:
Fermenting
- Fermentation typically occurs around 50°F — easily achievable with CoolBot Pro.
Lagering
If you need to lager beer at approximately 34°F, follow these recommendations:
- Insulate all surfaces (walls, ceiling, floor) to at least R-25. Rigid foam paneling is ideal.
- Seal all gaps and seams using spray foam and caulk to eliminate air leaks.
- Ensure the door has a well-sealed gasket.
- Limit door openings to fewer than 4 times per hour.
- If you're struggling to maintain 34°F, add a second A/C unit and CoolBot Pro for increased cooling capacity and redundancy.
Managing Fluctuating Temperatures
Some brewers require a range of temperatures—from ~35°F to ~60°F—during the brewing process. Achieving consistent control can be difficult if using large A/C units. To address this:
- Use a pass-through thermostat to control power to the A/C unit.
- Plug the A/C into the thermostat, and set your desired max temp on the CoolBot Pro.
- The thermostat will cut power to the A/C once the target temperature is reached.
- Ensure the A/C unit automatically restarts after a power outage (some default to 70°F).
