I have read and read and read about calculating strike/sparge water amounts. I usually start with a 7 gallon pre-boil amount and usually gets me down to 5-5 1/2 gallons after a 60 minute boil. I have yet to brew and AG beer but have some extract under my belt. I used brew target to run a few recipes through to see exactly how much water I will need for each. My grain bill is 8.75 lb. I calculated 1.25 qt/lb strike water and got 2.734 gallons of water for the strike water. If the run-off for the sweet wort after the hour long rest is supposed to be equal to the sparge run-off there is no way I am going to get 3.5 gallons from the initial run off. I'll end up with more of a ratio of 2 gallons + 5 gallons. Am I calculating something wrong???
