Hop experimenting

I edited Ale Guy's hop chart to have single numbers instead of percentage ranges to enable the making of charts and graphs to allow for some statistical comparisons of hops. E.g., I had to improve my hop recipe for an American pale ale after Marcellos didn't have any of the hops I wanted. The modified chart lets me compare the profile of a typical American Pale (lets say Cascase, Amarillo, Cluster) with my improv recipe of UK Northern Brewer, US Perle, Hallertau. The profiles are pretty similar aside from the extra Humulene, which should just make my beer smell better. I also expect to get sufficient citrus flavor from the high level of Myrcene from the Northern Brewer and Perle.

Anyway, I attached the spread sheet I edited incase anybody else wants to play with it. I just took the average of the ranges put in the original spreadsheet. I did this all quickly in my head so a few may be off a little bit but it still seems to work.

I'm brewing said pale ale tomorrow around 11 if anybody wants to drop in. I guess I'll call it Noble Pale or something like that.

interesting.Were those arithmetic means or what? How did you choose the single numbers? I personally find the percentage ranges to be useful. Varieties with small variations in the numbers can usually be used without altering quantities in recipes while those with large variations should probably have quantities altered to match the actual % of the hops in hand.
I know all the beer chemists have determined that one essential oil is responsible for a particular flavor and aroma over another, but I have found very little in the charts to substantiate that. I think you'll find the beer does not match the flavor profile you are expecting. But then that's not a bad thing as long as the beer is good.

Yes, just the average of the low and high number in the range. It isn't perfect but you can make some quick charts out of it. I did some internet and book searching and all I could find about the oils is that myrecene adds American-type citrus flavor and Humulene the aromas. Otherwise it was a lot of uncertainty.
