Hi. I'm confused and hope someone can enlighten me....
My recipe starts with 7.5 Gal of water, 1.25G boil off and 1.0 Gal Trub Loss, so I end up with 5 Gal in the fermenter (6 Gal in the kettle considering the 1 Gal of Trub). Beersmith says the IBUs are 34.7.
Same recipe, change trub loss to zero, so it appears I have 6 gal going into the fermenter (still 6 gal in the kettle)... Now Beersmith says the IBUs are 37.6.
I would think the IBUs would be the same either way since there is 6 gal left in the kettle at the end of the boil in both cases.....
Thank You!
