Despite coffee's popularity, there are no quantitative methods to measure a chemical property of coffee and relate it gustatory experience. Borrowing an electrochemical technique often used assess the oxidative reductive features molecules, we demonstrate that cyclic voltammetry can be directly ensemble strength beverage and, separately, how dark has been roasted. We show current passed for protonic precede hydrogen evolution linearly related strength. The same suppressed with subsequent...
Granular materials accumulate surface charges through triboelectrification and fractoelectrification—charging resulting from material friction fracture, respectively. These processes occur during coffee grinding impact production at both the enthusiast industrial-length scales. By sourcing commercially roasted as well roasting our own, we find that roast color grind coarseness charging; fine, darker roasts acquire charge-to-mass ratios comparable to those inferred particles in volcanic...
