Advanced Alpha Acid Calculator

For the simple alpha acid calculator click here

Use this tool when:

  1. You run out half way though weighing out your hops and your next packet has a different alpha acid.
  2. You would like to modify a recipe that calls for say 'Goldings' to have perhaps 'Challenger and Goldings'.

How to use

Fill in the 'Original Alpha Acid' and 'Original Weight' boxes with what the recipe first called for.

Click the 'Add new hop' button to enter a new hop/bitterness

Do this as many times you have hops.

The last weight box will fill itself in with the remaining amount of hops needed.
