Knock box is a container used in cafes and coffee shops to dispose of used coffee grounds (pucks) after brewing espresso. It's a convenient way to keep the workspace tidy and prevents grounds from clogging sinks or creating messes. Knock boxes are typically made of durable materials like stainless steel or plastic and feature a sturdy bar (bash bar) against which the portafilter is tapped to release the puck.
