Alpha to beta runs about 2.6:1, which is what governs how fast the bitterness fades in storage.

Oil composition

  • Myrcene55.1%
  • Humulene44.9%

Normalised to 100% so this hop can be compared like for like. The published components sum to 68% of total oil in the source data.

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.

Parentage unrecorded. Bred at Wye College, a daughter of Pioneer; released 2001.
