The verdict
Do you need a knock box? It is simply where a spent espresso puck goes: you rap the portafilter on the rubber bar and the puck drops into the bowl in one tap. At one or two shots a day, a compost caddy or the kitchen bin does the same job; a knock box earns its place when shots run back to back. Check what this listing is before you buy: Apexstone sells it as a built-in, drop-in box for a countertop cut-out, with a stainless steel bowl, a rubber knock bar, 1.5-litre capacity and a 6.9 x 6.4 x 4-inch body, and states it is dishwasher safe.
