Alpha to beta runs about 4.3:1, 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 0.8% 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:

  • Farnesene0.5%
  • Linalool0.3%

Aroma

  • Mint
  • Tropical fruit
  • Citrus
  • Pineapple
  • Pear

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.

Notes on this record

purpose defaulted to dual, unconfirmed -- was not researched individually for this bulk scaffold pass. Correct before publishing.

HopLove is an open dataset first and a website second. Every figure on this site is rolled up from cited observations in data/hops/, and the same build that made this page wrote ../../api/v1/hops.json β€” free, no key, no rate limit.
