{"title":"Knock boxes","description":"\u003cp\u003eAfter every espresso, a compact coffee puck remains in your portafilter, and it needs to be removed before you can grind again. Tapping it out over a waste bin only works halfway: the grounds fly everywhere, the rim of your portafilter knocks against hard plastic, and after a few months, you can see the dents.\u003c\/p\u003e\u003cp\u003eA knock box solves this with a rubber bar that you tap the portafilter against. The puck falls into the box in one motion, the rubber absorbs the impact, and the grounds stay inside.

That saves seconds per cup, which add up when there is a queue. You do need a cutout in the worktop, so measure the opening before sawing. Not sure?
