How have you configured your %utilization algorithm? You can find it in Session->Utilization. Make sure the algorithm used is similar in both programs. Thanks!

Hello

I've just checked now and I can't understand. Sorry, I'm not a pro.
Here my Beersmith settings:
Image

and yours:
Image

I've always a difference (44.53 on BTP vs 25.7 IBU in Beersmith)
I use standard settings... i've only change the standard on BTP on Tinseth.

Could you help me a little more?
I find BTP better, but i've a make a recipe and the IBU are not realistic with the settings... I will turn my beer into something wrong and I will not be happy when I will drink my brew :wink:
Thx for your help.

Regards, Dom

PS: I'm the only one in that case?

Thanks for the screenshots! Would you be able to send me a copy of both the BeerSmith recipe and the BTP recipe? I think looking at the actual recipes is the only way I can really see why there is a difference in the results, thanks!

Could the discrepancy be because the Beersmith Recipe is set to a 60 minute boil time, but the hops are being added at 75 minutes? The program might be calculating the IBU based on 60 minutes.

Boil Volume might be incorrect

Post by bzwrxbz »

Djavet, It seems the boil size might be incorrect on your Beersmith side (9L?). The Beersmith and BTP IBUs pretty much match up for me when I use Tinseth... and the same volumes.

Hope this will help:

Here's the recipes I use in Beersmith:
-> http://www.metadelic.com/upload/irish_red.bsm

And Beertools Pro version:
-> http://www.metadelic.com/upload/Irish_Red.btp

In my humble opinion, the Beersmith version are correct.
Feel free to download the recipe and test it. This one will be my next beer, monday a brew a "Daddy Porter", ready to drink in march 07 when my new child will com on earth!

You might want to read the post by bzwrxbz, above.
He seems to have solved your problem: You didn't enter the same volume in both recipes.

Hello

Thx, I will check this. But I don't think this will change a lot things
IBU 25 vs IBU 45...

The difference are too high.
I will check it tonight and will poste the "new" recipe.
I will also use the online tool to make the recipe and check the online data.

Regards, Dom

PS: The same recipe for 19 l. give me a IB of 33 in Qbrew.. Once again, something else (Thinset checked)

I believe it is such a large difference in IBUs because your boil volume is so small in Beersmith. It seems like you have it a bit less than half of what it should be. This will hurt your bitterness by a large amount. (25 vs. 45IBUs).

If you increase your boil size in your Beersmith recipe, you will see that your IBUs will start matching much closer to your BTP values.

cheers! :)

Yes I just see that. But My boil size are 9l. (3 gallons) and I wish make a batch size of 19l. (5 gallons).

How can I calculate the final IBU with a boil size of 9l. ?
What is correct way to do that?
