BrewFather vs Grainfather IBU calculations very different - HELP

[benoj]

Hi There,

I recently brewed a Saison and it's looking pretty good so far!

I originally designed the recipe using the Grainfather software - but I decided I wanted to have a go at brewfather software. So I've exported my recipe from Grainfather and imported it into Brewfather.

The estimates in Brewfather look slightly different for most things (couple of points either side - so all fine)

However - the IBU's are hugely different - 25 v 4!!!

GrainFather: https://drive.google.com/file/d/1exuAgFLacxCV6pYhUak3xD7qOto0G99d/view?usp=sharing
BrewFather: Brewfather

I tasted the wort and it definitely tasted bitter so I'm fairly sure the Grainfather is closer to being correct - any idea what's up with this / how do I use Brewfather without creating a super intense bitter beer in the future (if i was designing this recipe using Brewfather I'd have put 3/4x the hops in)

Thanks,

Ben

You have a very small boil volume, is that unintentionally?

Great spot - Must have been something strange in the import. Fixed that and all looks good now!

Thanks @schmurf
