I do 2 gallon boils w/LME. Room temperature water is around 75 deg (tap water the same) so I've drawn 5 gal of RO water and put 3 gal in the fridge. They are at 40 deg. Question: is there any kind of calculation about what temp to bring the wort down to mix with 3 gal 40 deg water to get around 70 deg in the fermenter?
