I don't grow hops, but as an amatuer chemist that follows this board quite a bit, I see a lot of people asking for how to test homegrown hop's alpha acids. It hit me today that one could get a rough estimate from testing the pH of the hop and comparing it to a previously made chart.
If there are acids in the hops, and by nature acids are acidic, and below 7 on the pH scale, you could test the levels of acids. Granted, you couldn't tell the difference between alpha and beta acids.
I might work on this once I get power back in my basement lab if people think this may work. I'd need to compile a chart of different hop varities's pH based on their acid levels.
