So I just finished my mash tun. It's a 5 gallon igloo cooler with a SS braid on the bottom. According to my sparge pal calculator, for 10 lbs of grain I need 3 gallons to mash in, and it says about 5 gallons to sparge. Taking into account absorption and losses, that should give me about 6-7 gallons to boil. I can only boil 6 at the most with my current size pot. Can I skimp on the sparge water and do something like 3-4 gallons? Or maybe lower my mash volume? I'm thinking I need a bigger pot...
By the way, this is for a 5 gallon batch.
