Hi all, please excuse all grain noob question, but how much water per lb of grain do you use for mash, and the sparge? If I follow mashing instructions I have read it is 1 to 1-1/4 quarts per lb grain for mash, then a half gallon per lb for sparge. If I use that as a guideline then I get like a min of 15.0 gallons of water for boiling, for a 5 gallon batch.? Am I way off or has the efficiency been considered and additional grain added? I am attempting this as my first batch over weekend, and the water volume is giving me some concern.
