Mosaic
Blueberry, mango and a dry herbal snap, which is why the name stuck — it lands differently depending on where in the process you put it. Whirlpool for fruit, dry hop for the herbal side.

What to swap it for
-
Seed parent. Drier, more pine.
-
Centennial 73
-
Idaho 7 68
-
Loral 67
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.
Pedigree
Simcoe. Simcoe crossed with a Nugget-derived male.
