Interactive tool

Calculate your batch

Change the example values. Inputs stay in your browser.

For 09:30, enter 9.5.

Your planned setup, mash and run-off duration.

Your planned boil, chilling and cleanup duration.

Use comparable measurements

Enter values measured at the same process stage and in the units shown. A calculation is only as reliable as its measurements and assumptions.

The displayed working makes each assumption visible. Record the inputs with the batch so a later result can be checked or improved.

Treat the result as a decision aid

Use the result to plan or compare a batch, then verify the relevant measurement on your own equipment. It is not a laboratory result, safety guarantee or package specification.

Before you use the result

  • Use the units printed beside each input.
  • Keep a record of the actual measurements.
  • Check equipment limits and process safety separately.
