Thought I'd try a pale ale recipe in Zainasheff & Palmer's Brewing Classic Styles. It's mostly light/Munich/wheat extract but includes a small Victory malt grain bill of .75 lb. Their recommended partial mash formula is 1.5 qts/pound, so I'd use 1.125 qts of water. Not much to work with! Need a smaller pot, obviously. They say to then transfer to a larger pot w/2 gal. of 165ยบ water, steep, and then to the boil pot. But I'm getting hung up on the numbers because the pre-boil volume is 7 gal., I'm doing a partial boil and want to work with 3.5 gal on the stove. I have no idea how much my partial mash will yield. Should I measure this, subtract that from 3.5 gal. and then add the difference to my final steep/boil water?
