Eureka Single Dose Blow-Up – rubber ring for low-retention single dosing
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.
What the Blow-Up ring is for
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.

What to pair it with
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.

Tip from our roastery
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.
