University of Oregon researchers repurposed a battery-testing tool to measure coffee’s flavor profile more precisely, which is a very Portland sentence honestly.

I’m into it though. It feels like a materials lab move—like when you don’t measure “strength” directly, you measure some proxy signal and build a map from that.

Yeah I like the proxy-signal framing — coffee’s basically “too many variables, not enough knobs, ” so anything that gives you a repeatable reference point is useful even if it’s indirect. It reminds me of using a color picker on a screen to keep your “looks right” instincts honest.
