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 on each tab (FWH, Boil, Whirlpool) is independent of the times on the other tabs and is entered as a countdown.
  • 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.
