FAQs
Hold the portafilter basket-side down over the knock box, then tap it against the covered knock bar to release the spent coffee puck. Use a controlled tap rather than striking the container’s edge. Wipe any remaining grounds from the basket before preparing your next shot.
Empty the spent grounds regularly, then wash the container with warm water and mild dish soap. If the knock bar is removable, take it out to clean around its mounting points. Rinse and dry the parts before reassembling, and check the manufacturer’s care instructions before using a dishwasher.
Common materials include stainless steel and sturdy plastic, with rubber or silicone often used for the knock bar covering and base. Some models combine a decorative outer housing with a removable inner container. Check the listed materials and care instructions when choosing one for your espresso station.
A countertop knock box collects spent espresso pucks in an open-top container. A drawer-style model collects them in a pull-out compartment, and some are designed to sit beneath a grinder. The main difference is how you access and empty the grounds during your espresso-making routine.
Empty the grounds into your household trash or add them to a compost system that accepts coffee grounds. For home composting, mix them with dry materials such as leaves or shredded cardboard. Avoid rinsing coffee pucks down the sink, where grounds can contribute to drain clogs.
