Galaxy IPA or DIPA Recipe help

P.S. Your point just "clicked" in my mind a bit better. I get how your idea that "more bitterness is perceived as a harsher bitterness" is akin to the writer of that articles method for debunking the Rigby study. The author claims that the higher cohumulone hops led to a beer with higher iso alpha acid, therefore the higher bitterness rendered the opinion of the tasters (with regards to the quality of the bitterness) to mere conjecture. Perhaps I took your earlier posts as claiming that higher bitterness = harsher bitterness. I'll have to reread them. Your latest post clearly indicates that your opinion is that higher bitterness = PERCEPTION of harsher bitterness.

Now again, the rub is that the author never actually states whether the "modern studies" assured that the two samples consumed by the sensory panel were actually equal in bitterness. If they were, given the fact that the modern sensory panel found no qualitative differences in the bitterness, those findings would again lend support to your point. If they weren't, then the opinions of the modern sensory panel would go against your point.

 

I just re-read your earlier posts. Your first post (the one I initially responded to) says more bitterness = harsher bitterness.

Then yesterday you softened your wording to more bitterness = judged as harsher bitterness

Then today you said more bitterness = gives an impression / interpreted (perceived / judged) as harsher bitterness.

So I disagree with what you said in your first post (which is what started our debate), but understand how the author tries to debunk Rigby's findings using a concept akin to the new way you phrased your claims yesterday and today (a meaningful change of wording that I didn't pick up on right away).

 

Interesting article. My takeaway from it is that the utilization factors in the various IBU models may need to be tweaked depending on the cohumulone fraction of total alpha acids. I'm not sure if there's enough data to do it though.

 

Actually, if you really desire to nitpick, my first reply to your article, I stated this:

My first post was made before I ever read your article, was phrased with a "supposed to" not a "This is 100% true." Your article also mildly changed my stance since it did bring new information to the table. However, it did nothing to prove the point you were trying to make, since it did tell me that cohumulone increases bitterness, which actually helped to verify my point.

 

Yeah and two sentences before that blurb, in the same first reply to the article, you wrote

We are now both on the same page. I now understand that your true claim is that more bitterness could easily be perceived as harsher bitterness (whether that perception is right or wrong) so I agree with the point you are making. I'll chalk this one up to me doing some sloppy reading and you doing some sloppy wording in this thread. Sorry for my end of the misunderstanding and thanks for keeping with the communication. Glad you hung in there long enough for me to understand your point.
