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.
YOUR MORNING COFFEE COULD BE MAKING YOU MORE TIRED, EXPERTS WARN: 'LIKE A ROLLER COASTER' 'It's an objective way to make a statement about what people like in a cup of coffee,' university chemist Christopher Hendon, the lead researcher known around campus as 'Dr. Coffee,' said in a news release. Traditional tests mainly focus on measuring the strength of coffee. Yet many other factors go into the way coffee tastes, including roast color and extraction strength.
The team's research shows how to move beyond measuring the strength of coffee alone to produce a more complete flavor profile cafés can replicate.

'Until now, we haven't been able to separate those variables. Now we can diagnose what gives rise to that delicious cup.
