At a Glance

This silicone espresso knock box combines a coffee grounds bin with a fixed tamping support. Knock spent pucks against the built-in post after brewing, or rest a compatible portafilter on its shaped top while you tamp.

The 1000 ml / 33.8 fl oz box has a front handle notch, a reinforced non-slip base and a rinse-clean silicone body. Choose Green, Gray, Black or Coffee Brown.

Key Features

  • One post for prep and cleanup. The integrated silicone support provides a cushioned contact point for puck removal and a rest for a compatible portafilter.
  • A compact place for spent grounds. The open square body collects pucks beside your machine, with a front notch for handle clearance.
  • Simple to empty and rinse. The support stays in place, while the silicone body and reinforced base can be rinsed clean.

How to Use

  1. Place on the counter. Set the clean, dry box on a flat, stable surface.
  2. Support the portafilter. Rest a compatible portafilter on the shaped post with the basket facing up. Hold the handle, check stability and tamp.
  3. Knock out the puck. After brewing, turn the basket face down over the box and tap it against the silicone post.
  4. Empty and rinse. Dispose of the grounds, rinse the box with water and let it dry.

FAQ

What does the integrated silicone post do?

The shaped post provides the contact point for knocking out used espresso pucks and supports a suitably shaped portafilter during tamping. It is molded into the box and is not height-adjustable.

Will this espresso knock box fit my portafilter?

Fit depends on the shape of your portafilter, its spouts and handle clearance. Check that it sits securely on the fixed support before tamping; basket diameter alone does not confirm compatibility.

How much space does this compact silicone coffee grounds bin need?

The top measures 15 × 15 cm / 5.9 × 5.9 in, the bottom width is 16 cm / 6.3 in, and the height is 6.5 cm / 2.5 in. Leave extra clearance for your portafilter handle and for lifting the box to empty it.

How do I clean the silicone espresso knock box?

Empty the spent grounds, rinse the inside and support with water, and let the box dry before using it again. The support stays attached during cleaning.

Do I receive all four colors or any coffee tools?

Each order includes one knock box in the selected color. Portafilters, tampers, cups, espresso machines and other photo props are not included.

What are the returns and import duty terms?

Yozcoffee offers 60-day returns under the store's return policy. Import duties are covered by Yozcoffee.
