One short tap and the puck drops into the cushioned drawer – quiet, clean and right at hand under the grinder.
The CKDC GroundsBreaker1 is a high-quality gastro knock box drawer that fits neatly under the grinder to save space. Finish: stainless steel.
The drawer is made of stainless steel and shock-absorbing cushioned, with ventilation slots. The unique, triangular knock bar spreads the force of knocking out over a larger area than round bars – meaning less wear and a longer service life.
Our opinion is one of many.

The drawer sits under your grinder: you'll find models in our coffee grinders, the puck knocked out comes from the portafilter of your espresso machine. Even tamping happens with a Tamper. Add fresh coffee beans from our roastery.

Fresh coffee makes the difference. For a full-bodied, chocolatey cup, go with Cozy Chocolate and Nutty Delight. For maximum body without acidity, the Very Nutty, for a lighter, fruitier profile, the Wild Peach. That's our recommendation, one of many.
