I'm having problems conducting a mash out and can't figure out a good method.
I brew 23l batches so roughly 5/6 kg of grain and 12/15l of mash liquor.
After an hour I may lose a degree or two at most so I need to raise the temp from 65ish up to 75.
I first tried by adding 5l of boiling water but this only raised the temp a few degrees, and if I sparge on top of this with boiling liquor the temp very slowly rises to about 72/73 by the end of sparging.
But I'm really trying to get the mash out temp up to 75 at the beginning.
I thought about using my copper cooling coil as a heat exchange using water from the boiler set to 75 and using a small pump to circulate, but before I go out and buy a pump, has anyone tried this?
