Well, not if you're using First Wort hop. I mean, you put the hops in the wort, not the mash, and boil for 60 minutes. They still will provide IBUs.

Are you maybe thinking of mash hops?

I meant to say adding to the wort, not mash. My mistake.

I saw a recipe for for Zombiedust that called for a First Wart Hop and the IBU was only about 18.1 with Citra. I put it in on Beersmith and it gave me a ridiculous IBU which would be way to bitter for any human to drink.

I just put in .75 oz of Citra at 60, I figure that would basically be the same as a first wort hop.

No, FWH goes into the wort during the first runnings and "steeps" until the wort is brought to a boil. It still gives the IBUs of the longer boil, but since the hops steep before the boil in the hot (150-170 degree) wort, it gives a smoother bitterness and not harsh. Some people calculate the IBUs of FWH as a 20 minute addition, but I feel that it still provides a typical amount of bitterness but in a less harsh way.

Adding hops at 60 minutes does provide bitterness, but it's not the same at all as FWH.

Try it yourself! Make one batch with tradition 60 minute hops and one with appropriate FWH. Then see if you like the differences.

Hmmm, not sure... is that possible??

Don't know about Beersmith 2, but on 1.4 under tools/options/bitterness you can plug in an adjustment for FWH. It is preset to +10%, meaning it will multiply the FWH weight by 1.1 for the IBU calculations. FWIW Promash has a similar entry, but it defaults to -10%.
