I am having a hard time with sparge water volumes on any bigger beers. If I follow the 1.25 quarts per pound of grain, by the time I drain that off I am only left needing maybe 2-3 gallons of sparge water. For example my first runnings just now netted me 4 gallons ... I only need 6 to the boil pot so no way can I split 2 gallons and have enough to do anything.
