Imagine your morning: perfectly controlled. Begin with freshly roasted beans weighed out to your preference and measured in a gleaming Eureka dosing cup. Load the beans into a beautifully crafted single dose hopper, open the slide, and start the motor. As the last few beans make their way through the grinding chamber and the tantalizing aroma of freshly ground coffee wafts into your nostrils, you’ll close the slide and push down on the hand bellows to ensure every last grind makes it out of the chamber and into your cup. There is nothing quite like single-dosing espresso shots, and the new Oro from Eureka does it in marvelous style.


One of the best names in home grinders has turned its attention to the latest trend gripping the home coffee world: single dosing. Choose a well-established brand for a newly established practice and get reliability and quality. The Oro has been designed and revised with great attention to detail and response to customer feedback, proving Eureka’s commitment to customer satisfaction.

“Eureka has been a leading company in designing and manufacturing modern and elegant coffee grinders since 1920”. No other manufacturer offers the same combination of performance and quality design as Eureka. Single dosing is rapidly becoming more and more popular amongst home coffee enthusiasts, and Eureka’s latest addition to their Mignon series pushes the envelope on the trend by implementing the technique on an already tried and tested grinder build.

The Oro is faster, quieter, and more compact than most other single-dosing grinders, offering the latest trend in the industry built into an already perfected grinding system. The Oro offers the same upgraded burr set and grinds quality as the XL, paired with new single dosing technology like its inclined design and blow-up hopper.

The Oro has a beautiful stainless steel dosing cup and a wooden seat to accommodate it, so you can keep your grinding space neat and tidy.

Using the Oro’s dosing cup, weigh out a dose of whole coffee beans, load them into the hopper, and hit the switch on the side of the grinder to activate the motor. Once enough beans have been ground you can close the metal tab to prevent popcorning and push down on the blow-up hopper to force as much ground coffee out of the chute and into the dosing cup as possible.

Our Assessment

Ease of use- hard.
Size - small.
Best used for - espresso
Serviceability - excellent


65mm ‘Diamond Inside’ Burrs: a large set of flat, stainless steel burrs treated with a special coating to last decades and designed to get consistent fines for better espresso shots.
Tilted Design: The idea to tilt the grinder is simple and effective. With an angled grind chamber, coffee is encouraged to fall through the chute and into your portafilter, as opposed to being retained by the grinder.
Single Dose Hopper & Bellows System: A beautifully designed single dose hopper brings a touch of elegance to this machine, and its bellows system helps achieve near zero retention by forcing air through the grind chamber and clearing out as much ground coffee as possible.
Powerful Motor: a more powerful motor allows this grinders burrs to run at a speed of 1650 RPM.
Silent Technology: The anti-vibration solution to noise. This grinder runs 20 dB quieter than the average, and is one of the quietest on the market. Note: This grinder is louder than the others in the Mignon series due to its more powerful motor.
ACE System: Eureka’s Anti-Clumps and Electrostaticity is designed to prevent clumping and spraying of ground coffee, giving it yet another edge over the competition.


Does the Eureka Oro come with a scale?

No. The Oro comes with a dosing cup and wooden seat for the cup to sit in while grinding, but does not come standard with a scale.

What is single dosing?

Single dosing is the art of using exactly the amount of coffee needed per shot, leaving no waste and preserving maximum freshness. Rather than storing several hundred grams of coffee or more in the grinder at once, a single dose grinder allows space for only one dose at a time and is designed to eliminate as much retention (leftover ground coffee from the previous dose) as possible.

Does the Oro come with a bellows?

Yes, the Oro comes standard with a bellows to help keep retention to near zero.
