The soft ring goes over the opening of the bean hopper, and with a short puff of air you push the last of the ground coffee out of the burrs. What remains is a grinder ready for the next fresh dose.
A simple rubber accessory that helps push leftover grounds out of the grinder when dosing by portion.
With single dosing you grind just one portion at a time – but some powder often stays behind in the burrs. The ring fits directly onto the bean hopper and seals the opening, so a puff of air pushes the remains down through the burrs. That way the freshly ground powder ends up in the cup, not in the machine.
Less residue means every portion stays fresher and more cleanly separated – especially when you switch between different beans. Espresso is complex, but not rocket science; small helpers like this one make everyday brewing calmer. We work with Eureka as a partner. Our opinion is one of many.

For anyone who grinds by portion and wants to keep the residue in the burrs low – especially handy if you switch between different beans often and want every portion cleanly separated.
The ring belongs with the grinder: you'll find matching models in our coffee grinders, brewing happens on your espresso machine. Our advisor tool helps you choose.
For clean portioning, a dosing cup fits well: affordable and precise, the Normcore Collection, especially finely crafted, the Weber Workshops Collection.
With the ring placed over the opening of the bean hopper, you push the powder left in the burrs down into the cup with a puff of air.
It keeps the residue in the burrs low – so every portion stays more freshly separated, especially when switching between different beans.
It's matched to the Eureka single-dose hoppers. In the showroom we're happy to check it against your setup.
Gladly. In our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) you can experience it live. Online we deliver in 2–4 business days, throughout Switzerland and to Liechtenstein.
If you switch between beans, you'll enjoy the variety. Our Cozy Chocolate and Nutty Delight bring full-bodied chocolate and nutty notes. For maximum body without acidity, the Very Nutty, for a fruity experience, the Wild Peach. That's our recommendation – one of many.
