Quick question for those of you who use a thermowell and a swamp cooler. how much temperature difference are you experiencing during active fermentation? between the swamp cooler water, and the core of the fermenter? Assuming the frozen water bottle method
I’d assume the temperature difference would be less with a swamp cooler (ambient water temp/core temp of fermenter). And the temperature difference would be greater in open air (ambient air temperature/core temp of fermenter)? is this correct reasoning?
some numbers would be great
