Hi Guys
New to this forum but certainly not to craft brewing.
I recently started using Beersmith instead of another package but after two batches of very bitter beer I found that Beersmith and the other software differs greatly in terms of how they calculate the IBU's in a recipe. For instance if I want plus minus 15 IBU's from a 9.6 Alpha hops at 30 mins boil my Beersmith says I need to add 32g while the other program says 17g. I have ended up with extremely bitter beer from my BS recipes so obviously the IBU's is wrong in BS. I have checked the setup of the hops and it's in both cases pellets at 9.6 Alpha Acid etc. This really makes me wonder what am I doing wrong because BS can not be that way off otherwise everybody would have noticed it.
Regards
