That's pretty much what I've been doing....let your tongue do the testing. :lol:
For rough IBU calculations, using the recipe calculator, I used only the ingredience for the amount of time it's actually being boiled then added the 2 figures together.

For instance, if adding exctract last 15 min. of boil, I put the grains and hops that would be boiled for the first 45 min. ran the calculator, then put in the grains, extracts and hops that would be in the last 15 min. of boil and ran the calculator again. I took the 2 IBU calculations and added them together to get the approx. total IBU.
So far, I think this gets it pretty close.

I've done 5 batches using the late extract method with good success. It does make the beer lighter in color, usually about 4 to 7 SMR lighter than the full boil SMR calculations. And it does seem to get rid of that scorched extract flavor.

Anyone else using late extract method? And what are your thoughts on IBU's?

What is "the late extract method"?

Postby billvelek » Sun Feb 03, 2008 4:27 pm

What is "the late extract method"? Are you boiling a weak wort and then adding either DME or LME late in the boil to increase gravity?

If so, and if that results in better hop utilization, then I suppose it would also make sense to do a split boil with one pot containing first runnings (higher gravity) but NO hops ... with all of the hops going only into the second pot with last runnings (weaker gravity).

Any thoughts.

Cheers.

late eatract

Postby slothrob » Sun Feb 03, 2008 5:49 pm

Yes, Bill, that's the late extract method.
I suppose it would work with wort as well to increase utilization, as you describe, as long as the IBU's don't exceed 100 IBU or so in the small volume boil.

Also, one of the other reasons for late extract addition is to decrease wort "carmelization" from the concentrated boil. I would guess that that would be increased in the second, concentrated, wort pot. So, I guess it depends on what you're looking for in the beer.
