Want stronger coffee with fewer beans? Pour from high up, study says

Researchers from the University of Pennsylvania conducted a study on brewing coffee using the pour-over method to reduce bean usage.

The findings suggest that controlling flow rate and pour height can enhance extraction efficiency and alleviate demand on coffee beans globally.
