Electrochemical tools for roast/strength QC
Key Questions
What is the Hendon potentiostat used for in coffee?
The Hendon potentiostat with cyclic voltammetry measures roast color and strength via electrical charge—more charge indicates stronger, darker roasts with less conductivity. It provides cheap QC without chromatography.
How does cyclic voltammetry assess coffee strength?
Passing electric current through brewed coffee reveals strength before sipping; higher charge correlates to stronger brews. University of Oregon research aligns it with TDS and espresso physics.
Why use electrochemical tools over tasting panels?
These tools offer consistent, objective roast/strength QC for baristas and roasters, skipping subjective tasting or complex chromatography. They enable cheat-sheets for reliable results.
Hendon potentiostat + cyclic voltammetry measure roast color/strength via charge (more=stronger, darker less conductive); skips chromatography for cheap barista/roaster consistency. Aligns TDS/espresso physics; high potential for cheat-sheets vs tasting panels.
