How much of a hop's aroma survives, given how it's used.
Dry hop and keg keep all of it. Whirlpool depends on temperature: 1 at
70 °C or below, falling linearly to 0.4 at 100 °C, because the oils boil off
faster the hotter the stand. Boil additions decay with time,
0.8·exp(-t/15), so ten minutes keeps about 40 % and sixty keeps under 2 %.
First wort is 0.05.
