Knockboxes

Many who buy nice espresso machines forget to get a knockbox to go with them. After each espresso extraction with your espresso machine, you will need to knock the spent puck out of the portafilter so that you can reload it for subsequent shots. This consists of a sharp "bang" of the portafilter against the bar that crosses the knockbox.

To keep your espresso machine area clean and professional looking, you absolutely need a knockbox that's built to take a hard rap to expend the puck. Choose a nice knockbox to complement your espresso machine's appearance.
