Subject: Hop aromatic data and request for Kirin II hops
Date: 1989-06-28 20:17:00 GMT

I was reading an article from THE AMERICAN SOCIETY OF BREWING CHEMISTS
"Changes in Hop Oil Content and Hoppiness Potential During Hop Aging"
Foster and Nickerson 1985, when I ran into the following...

Four catagoies of hop types became apparent...

1. High hoppiness potential when fresh and retains it after aging
Kirin II, Wye Challenger, Wye Target

2. High potential when fresh, lost after aging
Cascade, Galena, Brewers Gold

3. These show an increase of hoppiness with aging
Hersbrucker, Tettnang, Record, Fuggle, Blisk, Eroica, Hallertau, M.F.,
Willamette, and Styrian.

4. Low hoppiness when fresh, low when aged
(these were discribed as 'good keepers' but not good aromatic hops)
Negget, Cluster, Perle, Columbia, and Olympic

The Kirin II hop had and an aged 'aromatic' compound level of 9.68 micro-L
per gram, with a 'citrus' value of 24.56. Most of the other hops had values
in the 3.0 to 5.0 range! Does anybody on the net know where I can get some
of this variety of hop? It looks like a really good aromatic.

Thanks in advance...
