Alpha to beta runs about 3.7:1, which is what governs how fast the bitterness fades in storage.

Oil composition

Not enough of this hop's oil is accounted for to show a breakdown. The sources on file name components totalling 46.5% of total oil β€” most of the balance is myrcene, which the source for this record doesn't publish. Rather than scale what's here up to 100% and invent the rest, here is only what was actually measured:

  • Myrcene25%
  • Humulene21.5%

Scored on aroma overlap, oil composition and acid chemistry, then nudged up where a brewer has vouched for the swap by hand. An axis we haven't measured earns nothing, so a hop known only by its acid numbers caps out around 30 β€” the score is how much evidence there is for the swap, not just how close the numbers happen to be. Anything under 50 is a different beer, not a substitution.

Pedigree

Parentage unrecorded. Chinook grown in Slovenia, released commercially in 2019 and named for the strongman Martin Krpan.
