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. Country and international code from BarthHaas's variety page (their listed origin, which can be where it's grown rather than where it was bred).

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.
