Denny,
I've been looking at "Old Stoner" and doing some IBU calculations. You indicate in your recipe that the est IBU is 132. When I do the math I come up with 230 IBU. I also made the necessary adjustment for a 5 gal high gravity beer. Here are my results:

2 oz. Columbus Whole 18.30% @ 70 min = 103 IBU
3 oz. Chinook Whole 14.50 % @ 60 min = 262.8 IBU
1 oz. Centennial Whole 7.80 % @ 2 min = 4.5 IBU
Total = 230.1 IBU

Is the 132 a typo or are my numbers off?

I get about 370 IBUs from the numbers you have listed, but I find it hard to believe that 3 oz of chinook will net 263 IBUs!!!

Maybe there's a 5 gal vs 10 gal error somewhere?

Actually those 1st 2 oz. of Columbus hops should be FWH not 70 Min's.

I think!

My addition was bad........it is 370.3. Also, Michael what does FWH stand for? I've seen that but I'm not sure when that addition would be made?

It stands for First Wort Hopping. Put the hops in the 160 degree wort when you start draining the mash tun.

Consider the FWH as having the IBU equivalent of a 20-25 minute addition.

Just so I'm clear on this. Add the 2 oz. of Columbus to the mash?

Sorry - my note wasn't clear - put the hops in the boil kettle when you start draining the wort into the kettle.

Yes, exactly. That's the definition of first wort hopping--adding the hops to the kettle as you drain the first runnings from the mash. Adding the hops to the mash itself is known as mash hopping and is something else.

Bierview -- FWH do not add to the mash; add after you mash-- Add the hops to the kettle as you run off your first wort runnings.

Conventional wisdom says you probably reach hop saturation at 100 IBU or less. Of course only an idiot would expect something like "Old Stoner" to be conventional. Brew it up and don't worry about +/- 100 IBU math errors....they are only estimates anyway.

132 was from memory, and at this point in my life, I shouldn't be held accountable for poor memory!!! I'm gong to start a new thread with both the Old Stoner recipe and the dunkel recipe Bill asked for.
LIfe begins at 60...1.060, that is.

Denny,

132 is from a recipe I printed on 12/31/04.
20 lbs. 2 row
4.5 Munich
1.75 Cara Munich
.75 60L

That sound right for a 5 gal batch?
