Knock Box

Term from Cafes industry explained for recruiters

A Knock Box is a basic but essential tool used in cafes and coffee shops for collecting used coffee grounds. It's a container, usually made of metal or durable plastic, with a rubber-covered bar across the top. Baristas tap or "knock" their portafilters (the handle that holds coffee grounds) against this bar to remove used coffee grounds after making espresso. This tool helps keep the workspace clean and efficient, allowing baristas to quickly prepare multiple coffee drinks. The term often appears in job descriptions as part of café equipment knowledge requirements.
