Also, with an 18% oats ratio I was reading that I should do a 3 to 1 ratio during the mash of water to grist. Does that sound right?
How much water should I sparge with?
Once the sparge is done and I begin boiling the wort how much should I reduce it?
Looks like it was a 5-6gal batch depending on the expected OG.
assuming you mean 3qt to 1lb for the mash, that's way too much, thats about what your total volume of water should be. having more oats might make it a lil gummy, but shouldn't be enough to be an issue. I recommend toasting them a lil first to develop a bit more flavor from them.
how much water to sparge with is basically enough to get you to your pre-boil volume. there is about a 0.12 gal/lb grist absorption during the mash and you need to compensate for boil off (differs system to system, but typically about 1gal/hr), so whatever that comes out to be. if shooting for 3Gals, about 9-10qts for the mash and same for sparge should work fine
