Rhino Knock Box – compact for home espresso puck disposal
A short, firm tap – the coffee puck releases from the portafilter and drops cleanly into the box, before that first sip is even possible. For many home baristas, this exact moment becomes a small ritual: the knock, the sound, the anticipation of the espresso that follows.
That anticipation is more than a mood. Dopamine is released while you're expecting something, not only once you taste it – a recurring ritual like knocking out the puck is part of that. The Rhino Knock Box is there for exactly this moment: small enough for the counter, sturdy enough for daily use, and available in three colors to match your kitchen.
The knock bar in the middle absorbs the impact and protects the portafilter. No knocking into the trash, no mess – the used puck always lands in one place.

Who it's for
For anyone with a portafilter machine at home who wants to knock out the used puck cleanly and within reach – especially where space is limited. Whether you even need a dedicated box, or the compost bin does the job just as well, is ultimately a matter of taste – our opinion is one of many. You'll find the right machine or grinder in our coffee machine and coffee grinder selection.
What goes with it
Tampers and a WDT tool ensure a clean puck beforehand. Cleaning products for machines and grinders can be found in machine and grinder cleaning. For those who need more volume, larger Rhino models like the Knock Box Deluxe are in our Barista Equipment.

Roastery Tip
For the coffee that lands in the freshly knocked-out box right after, we usually recommend Cozy Chocolate or Nutty Delight from our own roastery – dense, aromatic, full of body. If you want maximum body with zero acidity, Very Nutty is for you. And if you're curious about a fruity experience, Wild Peach is always worth discovering. That's our recommendation, one of many – any bean, even one from the supermarket, works just as well in the knock box.
