Since I know a lot of brewers out there use the 10 gallon round cooler as a mash tun, could somebody tell me how much they account for heat loss when not preheating the tun? I know ambient temp etc will be a factor, but maybe some ballpark figures or even better a link to a calculator pertaining to this particular cooler would be great. I have done 2 AG batches so far, both with my cooler. The first I guessed and went for 8 deg above may target, and ended up about 2 deg low. The second batch I tried 10 deg above and still ended up about 2 deg low. Both times it was around 55 deg outside (not exact.) I dont have a recirculator so raising and lowering is a step I would like to avoid without 50 trial and error batches that I'm sure somebody has already done. Thanks in advance for any input.
