The scientists using electricity to assess the consistency and flavor of coffee
Researchers at the University of Oregon are exploring a new method to assess coffee flavor using a potentiostat, a tool typically used for measuring battery charge. This approach allows for a quantitative analysis of various flavor characteristics, such as acidity and intensity, which are often overlooked by current industry standards. The scientists found that their method performed comparably to human experts in evaluating coffee quality.
- ▪The University of Oregon researchers are using a potentiostat to measure coffee flavor variations.
- ▪This method provides a quantitative assessment of qualities like acidity and intensity.
- ▪In tests, the potentiostat method matched human experts in identifying subpar roasts.
