Electrical current might be the key to a better cup of coffee

University of Oregon researchers say electrical current can help probe coffee flavor, offering a new way to evaluate coffee chemistry.

Related research found that misting beans with a little water before grinding reduces static electricity and clumping.

Less static led to smoother espresso flow, better consistency, and potentially less waste in brewing.

The findings could give coffee makers a simpler, more reliable way to assess flavor and control extraction.
