Scientists used electricity on coffee and discovered what makes it taste good

An inconsistent cup of coffee can make or break your day — but new research is shedding light on just how the industry can dial up the production process for a more reliable flavor.

University of Oregon researchers repurposed a tool called a potentiostat, typically used to test batteries, to send an electrical current through coffee. 

Through this simple process, they were able to identify coffee's "chemical fingerprint" that determines the drink's flavor.
