WHAT IS A KNOCKBOX?
A knockbox (informally known as a "bash bin", "coffee column", "slam piece" or "bang bang") is a device used to store spent espresso grounds, called a puck, after a shot of espresso has been pulled.
Knockboxes are an essential item for every espresso machine set-up. Brewing great espresso can get messy, however, it is easy to keep the mess at bay with the right knock box. Whether it’s for home use, semi-commercial use, or even use at a full-fledged coffee operation, we’ve got you covered with the right knock box or knockbox drawer to suit your needs!
