Direct electrochemical appraisal of black coffee quality using cyclic voltammetry - Nature Communications

Coffee flavor is primarily determined by the bean roast color and concentration of the beverage. Here, the authors show that both of these characteristics are reflected in the coffee’s cyclic voltammogram. This approach enables rapid determination of the strength and roast intensity of the coffee.

Building A Multi-Purpose Electrochemistry Device

We don’t get enough electrochemistry hacks on these pages, so here’s [Markus Bindhammer] of YouTube/Marb’s lab fame to give us a fix with their hand-built general-purpose electroc…
