What type of equipment is a Knock Box?

A Knock Box is primarily classified as a cleaning tool. Its main purpose is to provide a convenient and hygienic way to dispose of used coffee grounds after brewing espresso. Baristas use it to knock out the spent coffee puck from the portafilter, keeping the workspace clean and organized.

While brewing tools, measuring tools, and serving tools serve a different primary function within the coffee preparation process—focusing on extracting coffee, measuring ingredients, and presenting beverages to customers, respectively—the Knock Box does not perform these roles. Instead, it streamlines the maintenance of the barista’s station by ensuring used grounds are easily collected and discarded, thus emphasizing its role in cleanliness and efficiency in a busy café environment.
