Static electricity
Static electricity is the phenomenon where electric charges accumulate on the surface of a material without movement. In specialty coffee, this can affect the grinding and brewing process, causing coffee particles to stick together or cling to equipment, reducing efficiency and impacting extraction quality.
To address this issue, measures such as humidity control, using a conductive grinder, and minimizing friction during grinding can be applied. These solutions help coffee powder remain loose, maintain their original flavor, and reduce the negative effects of static electricity.
