How to use it
In Mbrew, open Tools and select Bitterness.
Enter the following values using the units shown in the app: Hops, addition time, wort parameters.
Review Estimated IBU, then compare the inputs and result with your batch plan.
Interpreting the result
Enter each hop addition separately, including alpha acid percentage and contact time. Estimated IBU depends on the model and wort conditions; dry hopping and sensory bitterness need separate interpretation.
