I'm just starting my first all-grain right now, woo! I'm doing a half recipe and using the easy stovetop all-grain thread as a guide. Anyway, my mash is going right now and I hit my target temp perfectly. Now I'm wondering how much strike water to use.
Here's what info I can give. 5 lbs of grain is mashing in 1.25 gallons of water currently. Now that it's cut in half, the batch size will be 2.5 gallons. The normal recipe calls for a 3 gallon boil, but I honestly don't know how this should be altered.
Basically what I need to know is how much sparge what I need to use, and what my boil volume should be. Thanks.
