As a Linux user, the only reasonable brewing app I have available is Brewtarget. I've noticed IBUs calculated by Brewtarget are significantly lower than those calculated by online tools, such as the one available through this forum.
eg. 27 litre boil; 22 litre batch; 1.050 OG; 50g hops; 7.5 alpha; 60 min boil...
Online calculator (Brewer's Friend) = 42.73 IBU
Brewtarget = 33 IBU
On researching the reason for this it appears there are three methods for calculating IBU based on research by Reger, Garetz & Tinseth. Brewtarget defaults to Tinseth's approximation while the online tool above must be using Reger's.
I found a setting to configure the method used so, In the interests of standardising my recipes with everyone else's, could anyone that designs their own recipes let me know what method their software uses?
I believe the most used software is Brewsmith, which appears to default to Tinseth. Is that right? Should we all configure our software to tie-in with Brewer's Friend?
