How come when I rescale a batch in Beersmith it makes the IBU's too high?
Right. If you boil a certain volume of hops in 2 gallons of concentrated wort, you will extract a lot less bitterness than you would if you were boiling in 5 gallons of less concentrated wort. The first time I did a full boil using an ingredient kit designed for a 2 gallon concentrated boil, I was rather unpleasantly surprised at how bitter the beer came out, so I learned my lesson pretty quickorfy said:Hop utilisation changes with volume.

FlyGuy said:I use Beersmith a lot, and have never seen this problem. Are you sure you are using the software correctly? When I double a batch (say from 5 gal to 10 gal), it works perfectly for me, both in version 1.3 and 1.4.
As was mentioned above, you probably have a problem with the boil volumes you are calculating. Beersmith is sensitive (good thing) to the equipment you use and the boil volumes it can handle. Check there - I suspect it is your problem.
If not, please provide some further detail so that we can replicate the same thing so that we can help you to fix your problem.
Glad you got it figured out. The equipment profiles are a bit confusing at first, but they provide some really high level control over your brew design.WBC said:I finally tried to change my equipment and once everything was tripple checked I tried to resize and it worked correctly. I just have to get used to what affects other things when using all the settings. I am trying to evaluate the program and was considering what program to buy. Have you tried others. I was using Promash and was trying others to compare.
Sounds great -- that's one of my favourite styles! Beersmith and ProMash are both great tools to help with that recipe formulation, too. And I am sure that if you spend the $20 to buy Beersmith, you won't regret it.WBC said:Thanks Flyguy, I am brewing N. English Brown Ale today and I used Beersmith to design it. I am making a newcastle clone. Thanks for the vote of confidence in Beersmith. I am going to purchase it.
