Where it's grown

In 2025: 1,719 acres in Washington, 487 acres in Oregon, withheld in Idaho (NASS withholds a figure when it would identify a single farm). That's at least 2,206 acres. No. 7 by acreage in Washington; No. 3 by acreage in Oregon.

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.
