I've been reading about people who have cooler mash tuns. I guess they mash with a small volume of water, run it all off into the brew kettle, then dump the rest of the water needed to get the correcyt pre-boil volume into the mash tun, and run that out as the sparge. But this seems like extra effort compared to just adding all the water at the beginning of the mash and using all of the water from the start. Is there a chemical difference or do people just do the 2 runnings method so they don't need a giant mash tun (I guess you would need 10 or more gallon mash tun to do no-sparge for a 5 gallon batch)?
