If you ever tried to remove used espresso grounds from a portafilter, you know it’s sort of a dirty task. That’s where a knock box for coffee is a game-changer a low-profile yet very useful gadget that allows you to quickly, cleanly, and easily get rid of coffee pucks.
What Is a Knock Box?
A knock box is a tiny wastebasket with a bar along the top designed to knock out used coffee grounds (officially known as “pucks”) from your portafilter. Instead of scraping or slamming your portafilter into the trash can, you tap it against the knock bar, and the puck drops into the wastebasket neatly.
Why Every Home Barista Should Have One
- Cleanliness and Efficiency
No more splattered grounds or dirty counters. A knock box keeps your workflow clean and your station organized. - Protects Your Portafilter
Knocking your portafilter on hard surfaces can damage it over time. The rubber bar in a knock box provides a cushioned surface to tap against. - Encourages Proper Cleaning
Having a knock box makes it easy to dispose of grounds shot by shot—keeping your gear clean and prolonging the life of your espresso machine. - Recycle Your Coffee Grounds
Having a dedicated container makes it easy to catch grounds for recycling—like in your garden, compost, or even skincare.
