What's the best way to figure out what temperature my beer is inside my food-grade bucket? I guess I could take the lid off and stick a thermometer in but I'd rather not do that.

how are you controlling temperature? you could use the ambient temp as fermenting wort usually rises 5-10 degrees over ambient temp

Right now it's in a bathtub with the fan running.

Maybe something like this?

people on here told me to keep my swamp cooler about 5 to 10 under my desired fermentation temperature and its worked for me well

That works through the plastic?

Best? A stainless thermowell through the stopper. This will run you about $15 and assumes that you have an RTD or thermistor that will fit inside of it. Also assumes you have a stopper and are willing and capable to drill a second hole through it.

Barring that, I wouldn't go sticking stuff in there. The water bath and some assumption about the temp of the beer vs the water is probably the best.

That's what I use for my bucket fermenter.

Yes it does, and is accurate enough for these purposes.

I'm posting because I'm wondering if I'm missing something. Can you get an accurate enough temperature by placing a thermometer on top of the bucket? I know this is ambient air temp, and the fermentation adds some heat to the liquid in the bucket, but isn't the ambient air "good enough"? (yikes! I hope so, because if not, then I'm not monitoring my temp close enough!)
