Can you elaborate on the process? I'm not suggesting that I'm going to start up a hop measuring business or service (I'm fairly certain I don't have access to the lab equipment required). I'm just curious about how it's done.mrkristofo said:Mail them to me, and I can do it. Seriously, it's quite easy if you have access to the instruments and the mad geek skillz.

RoaringBrewer said:You should start making a buck (notice I said a buck, not hundreds of them! ) off HBT'ers who want to have their hops tested! Sweet deal...
mrkristofo said:I don't want to make any cash off of it, because the instruments in the lab are provided by federally funded grants. Making money off of it is probably illegal on a few different levels. But I can geek out and scan whatever I want. So I'll just take payment in a different form of green...keeping the extra hops I don't need for the extraction.

EDIT: I double-checked some Willamette leafs I got from the LHBS listed at 4.7%...I calculated them to be 3.1% after 2 years. Not bad. I also double-checked some 2007 Targets at 11.7% and I determined them to be 11.64%.
mrkristofo said:There's a paper on it in the JASBC if you want the real nitty-gritty, but basically it's a UV absorbance spectra after an organic extraction of the alpha and beta acids from a specific mass of hops. Determine the concentration of alpha and beta, then extrapolate those numbers out to a mass/mass ratio with the hop matter.
That will give you a %alpha and %beta numbers.
You can determine % humulone/cohumulone/isohumulone using HPLC.

Great Idea! Come harvest season I know several growers who definately wouldn't mind parting with some of their hops for an Alpha acid reading in return.mrkristofo said:I don't want to make any cash off of it, because the instruments in the lab are provided by federally funded grants.

GilaMinumBeer said:Could you provide the link? I went to the ASBC and searched hops. It resulted in 10 pages of journal publications. I like to read the Nitty Gritty, even if I don't actually abide by it.
Check post 4 and PM him.I'm still waiting for the address to send the mystery hops for analysis...
I have some Cascade and Nugget, could you test these for me?Mail them to me, and I can do it. Seriously, it's quite easy if you have access to the instruments and the mad geek skillz.
