Eureka Oro Single Dose Pro – Single-Dose Grinder with 65 mm Blind Burr
Weigh the beans, pour them in, grind: the Eureka Oro Single Dose Pro is built for freshly ground coffee shot by shot, for espresso and filter. Eureka calls it the «Mignon Single Dose Pro» and places it in the Oro line.
The grinder combines a grinding chamber inclined at 15 degrees, a new zero-retention grinding chamber, an upper 65 mm blind burr without screw holes and the Blow-Up system. According to Eureka, this reduces retention by up to 70 percent compared with the previous Mignon Single Dose. It is made by Eureka in Sesto Fiorentino near Florence. Available in matte black, white and chrome.
Features of the Oro Single Dose Pro
Anti-retention system
The design inclined at 15 degrees and the reworked grinding chamber keep the path of the ground coffee short. Eureka states a dose consistency of ± 0.15 g for espresso and ± 0.05 g for filter.
Upper 65 mm blind burr
The upper burr has no screw holes. This is meant to lower retention further and, thanks to the wider grinding surface, deliver a more even grind.
Diamond Inside burrs
The burrs are made using Eureka's patented Diamond Inside process with a modified crystal structure. According to Eureka, they stay sharp longer and keep the grind size consistent over a large amount of coffee.
King Size Dial with rotation counter
The large, patented dial adjusts the grind size steplessly and micrometrically. The rotation counter shows how many turns you have made, so switching between espresso and filter stays repeatable.
Silent Technology
An anti-vibration system reduces grinding noise. Eureka therefore describes the grinder as quiet enough for café and home.
Anti-Chaff dosing funnel
The funnel on the 80 g metal dosing cup keeps ground coffee from spilling while dosing. Via the outer ring, you pour the grounds directly into the portafilter.
Compatible with Black Diamond burrs
Eureka offers Black Diamond burrs for the grinder (Diamond Inside plus DLC coating), in the versions Espresso Specialty, Italian Espresso Taste, Brew Special and All Purpose. According to Eureka, no seasoning by the user is needed thanks to its own seasoning process.
The details in everyday use
The shatterproof 45 g bean hopper has an anti-popcorn system and a shutter at the bottom. With the Blow-Up system, you blow the last remnants out of the chamber after grinding. The ACE system (Anti-Clumps & Electrostaticity) reduces clumping and static charge.
Starting and stopping is done by hand using the button on the side. Eureka recommends grinding no more than 160 g per grinding session. You can remove the rotation counter knob for cleaning without changing the grind setting.

Who it is made for
For everyone who grinds fresh for each shot and often changes beans, whether for espresso or filter. If you would rather have a grinder with a bean supply and grind-by-weight, you will find more models in the Eureka collection and among our coffee grinders. Other single-dose grinders: the affordable Varia VS3 from the Varia collection, and more from Option-O and Weber Workshops.
Our advice tool helps narrow down the choice. A free consultation in the showroom, by phone or online is possible. In the comparison workshop in Zurich Oerlikon, you can test grinders and machines side by side, and Eureka is part of the selection there. Both are an option, not a requirement.
What goes with it
The grinder pairs with any portafilter machine from our espresso machines. For everyone who wants scales that are affordable and precise: Normcore. If you want an app and flow-rate display: Acaia. Tampers and WDT tools are available affordably from Normcore, and with more elaborate materials from Weber Workshops.
Purchase and delivery
Delivery throughout Switzerland and to Liechtenstein in 2–4 working days. Click & Collect in Bern, Gerberngasse 44 and Zurich Oerlikon, Hagenholzstrasse 50b. Financing available. Questions to [email protected] or by phone during business hours.
Frequently asked questions
What does single dose mean?
For each shot, you weigh out exactly the amount of beans you need and grind them straight away, with no supply in the hopper. That way you can change beans at any time.
How much coffee stays in the Eureka Oro Single Dose Pro?
Eureka states a maximum retention of 0.55 g at espresso settings and 0.05 g at filter settings. The inclined grinding chamber, blind burr and Blow-Up system work together to achieve this.
Is the Eureka Oro Single Dose Pro also suitable for filter coffee?
Yes. Eureka states a grinding speed of 3.0–4.1 g/s for filter. The rotation counter on the King Size Dial helps you switch between espresso and filter settings.
How big is the bean hopper?
It holds 45 g and has an anti-popcorn system. Eureka recommends grinding no more than 160 g per grinding session.
Can I see the Eureka Oro Single Dose Pro before buying?
Yes, in our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Not every model is on display at all times; drop us a line beforehand at [email protected].
Tip from the roastery: Single dosing shows its strength when you change beans. For espresso, with 1:2 as a starting point, Cozy Chocolate or Nutty Delight. If you like maximum body without acidity, Very Nutty is the one. For a fruity filter experience, Wild Peach is a good match. This is our recommendation, one of many.
