Hallertau Mittelfruh

The definition of noble. Soft herbal spice, a little floral, no sharp edges anywhere. Fragile in storage and low in alpha, which is the price of it.

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 — 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.
