60
Hop quantity in grams =
Bitter units (BE) × litres of beer × 10
% alpha acid × % bittering agent utilisation
Formula for the hop quantity
With a total cooking time of 80-90 minutes, a bitter substance utilization
of 30 % can be assumed.
Example
200 l of wheat beer with a bitterness content of 15 BE are to be brewed.
The available hops have an alpha acid content of 3 %. This results in the
following hop quantity, which is added at the beginning of the boiling
process. The hops added shortly before the end of the boil are not inclu-
ded in this calculation, as no significant quantities of bittering agents are
released into the wort during this short period.
