Default First All grain batch---something isn't adding up!

Ok, so I am going to make my first all grain batch and I am going off of a pretty vague clone recipe for the Stone IPA Ruination. 5 Gallon batch

I've got 15 lbs of grain and it's asking me to mash with 1.5qts/lb of grain= 5.625 Gallons.

Then its saying that I should sparge with 2 qts per lb of grain= 7.5 gallons

So, I am looking at a total boil of 13 gallons?????

Perhaps someone could show me where I've gone wrong, or, give me another solution.

Thanks

How big is your kettle?

You can mash at 1.25 quarts/lb of grain, but going below that would likely get pretty thick. I'm not sure I've ever gone with less than 1.25/lb, so somebody else may know better from experience. 1.5 is more than I've done.

Don't forget absorption of approx .1gallons/lb of grain, so back that out of your boil numbers.

For sparge water, you'll just add as much as you need to make up your final boil volume. You won't likely need 7.5 gallons for that.

So, at 1.25 qts/gallon, you're looking at just over 4.5 gallons mash water less absorption of 1.5ish gallons, plus sparge water to make up final volume.

You need about 7.5 gallons pre boil...

What software are you using? It is compensating for some HUGE system water loss or large boil off rate would be my guess.

Shooting from the hip I'd say:

1.5 quarts per pound for mashing is fine. (You'll end up with maybe three gallons of wort)
Sparge with two 3 gallon batches and on the second batch sparge, stop at around 8 gallons pre-boil.

The bigger the beer, the longer you can expect to watch the pot boil.

Actually, I didn't even think about grain absorption.

Software I am using is Beer Smith.

I have a 10.5 gallon kettle.

Grain absorption will only be about 2 gallons...

Hard core.

Either stop drinking now and let higher intelligence guide you.

Or drink more and receive drucken intervention from the brewing Gods.

Either way...you win.

ok, so I'm following a conglomerate of advice here, mainly yours ^^^^ and by warmth in my stomach and my desire for another beer, the intelligence and the drunken intervention are battling it out pretty darn good.

So, I am getting ready to sparge my first 3 gallons as you suggested. Do I just slowly pour it in after taking the first run off through and such? or is there a better method?

Well, man, you chose a very ambitious beer fir your first AG. Run your sparges off slowly. If you are batch sparging, stir the bejebers out of them and give them a good 10 minutes or so to rest. Sparge whatever you need to get the fermentables you need, and then boil off whatever you have to. Don't start tossing hops in the mix until you see where you are on the gravity curve (i.e., until you know when you've boiled off enough to reach your target gravity and volume).

And. although it's probably too late. sober up if you can. Brewing with a buzz can be an awful lot of fun, but it's no way to learn anything (other than brewing with a buzz tends to lead to many mistakes).

I hope this turns out well. No matter what, I strongly recommend an easier beer for your next AG brew. You need to learn a bunch of technique. Friggin' Ruination can be a challenge for even experienced brewers.
