University of Oregon researchers used a potentiostat—normally a battery-testing tool—to run electrical current through coffee and identify a chemical fingerprint tied to flavor, not just strength.
The method separates variables such as roast color and extraction strength, giving cafés and roasters an objective way to diagnose what makes a cup taste good and reproduce it more consistently.
Four samples from the same English roaster showed the system could spot one defective batch that had passed visual quality checks despite looking identical to the others.
Nature Communications published the findings, but consultant Bryan Quoc Le said adoption may take time because the approach still depends on expensive components even as it offers a measurable way to assess subjective taste.
Could a chemical fingerprint soon tell you which coffee you will love before buying it?
Will a 'perfect' coffee formula kill the artistry of coffee roasting?
