>Here we show that cyclic voltammetry can be used without any additional sample preparation to directly measure the strength of a coffee beverage and, separately, how dark the coffee has been roasted; these two properties are implicated in the sensory profile of the beverage.
those two properties do not even touch on the quality of the beans, nor how those flavors are developed and maintained through roasting. measuring the darkness of roast does not tell you how dark the coffee should have been roasted for optimum flavor profile.
It took me a few vids to warm up to his presentation style and the production style, but now anyone else doing coffee vids seems like a total amateur/influencer/YT rusher. Early Hoffman coffee competitions were the proof point for me that he’s not simply an influencer entrant.
His presentation still is still a bit forced and orchestrated to me, but at least I believe he’s smart and has interest in the craft.
I suppose this might be useful for making full-auto coffee machines that can self-adjust parameters like grind size, water:coffee ratio, tamping strength (for espresso style machines) etc. Although there's plenty of things to measure already, they don't really directly check correct brewing. This could help improve a lot.
The title says "quality" but the summary seems to say it only measures the "strength" oand "darkness of roast". Certainly won't measure how good it tastes. Given these are the two properties purportedly measured, I imagine you'd get the same results regardless of tastiness and age of the coffee or beans.

Waiting for him to appear in the YouTube shorts Brooklyn Coffee shop now I think about it.
