I mash at 1.5 qts/lb and sparge until I get my desired preboil. For this, doing a 15 gallon batch, I mashed with 11.25 pounds, then sparged until I got to 15 gallons. I boil in a keggle, then just topped off with water after my boil to get to 16.5 in fermentors.
I'm serving this keg on the 16th, going to lager this on gelatin for the next week and rack to keg the week prior to force carb.
