IBU - Diversity Methodology

This tool estimates beer bitterness using new Diversity Methodology (part one, two, three and four - in Czech only).
Note: This tool uses shared hop database. It is possible to add new hop into it.

Notes:
  • Tool is available only for registered users.
  • Choose units.
  • Enter wort gravity and wort volume (where volume is amount of (already cooled) wort in boil kettle before it's transfer into fermentor - i.e. including trub).
  • The time in each tab (FWH, Boil, Whirlpool) is independent of the times in the other tabs. The time in each tab can be entered in descending or in ascending order.
  • It is very important to specify not only times of hop additions but also the times of temperature changes.
  • Check the result of calculation in the table and chart found on the tab . If curves in the chart are not correct, please change your input values.
  • Some typical examples can be found on the tab
