The Mignon Single Dose PRO is the evolution of Eureka’s benchmark single-dosing grinder, developed for coffee professionals and enthusiasts who demand ultimate precision with minimal waste.
While retaining the core strengths of the original Single Dose — such as low retention, compact design, and high grinding quality — the PRO version introduces a new level of engineering that enhances both performance and workflow.
One of the most significant upgrades lies in its new ZERO Retention Grinding Chamber, meticulously redesigned to eliminate residual coffee and drastically reduce retention. In combination with the new 65mm upper blind burr, which has no screw holes to prevent grounds build-up, the grinder delivers a noticeably cleaner and more consistent grind path.
These internal improvements, together with the proven 15° inclined body and the integrated Blow Up system, ensure close-to-zero retention even during heavy use and improve coffee retention up to 70% compared to former Mignon Single Dose.
Another major enhancement is the King Size Grind Dial, now equipped with an integrated revolution counter, allowing for easy ultra-fine micrometric adjustments. This is a major leap forward in dialing in with precision, especially for those who switch frequently between brew methods.
The PRO introduces a redesigned Anti-Chaft Funnel that reduces coffee waste and keeps your grinding area cleaner. A more robust, unbreakable bean hopper with Anti-Popcorning System ensures stable and silent bean feeding, while the new 80g anodized metal dosing cup offers a perfect fit for both espresso and filter coffee doses.
To further personalize the grinding experience, Eureka offers Black Diamond Burrs, accessory burrs specifically engineered for the Single Dose PRO. Each variant is optimized for different roast profiles and brewing methods, ensuring maximum flavor clarity and optimal particle distribution. Thanks to the Black Diamond treatment, these burrs maintain their optimal cutting edge and particle consistency far longer than standard burrs—delivering long-lasting durability and high-performance grinding over time.
Mignon Single Dose PRO is built with a motor covered by a 10-year warranty starting from June 2025. This milestone reflects Eureka's dedication to setting new standards in grinder reliability and supporting customers with long-term product assurance.
Mignon Single Dose PRO is more than just an upgrade — it's a professional-grade grinder that refines every element of single dosing. Whether you're chasing clarity in pour-over or dialing in for the perfect espresso shot, the Mignon Single Dose PRO is built to meet your exacting standards.

The questions we are asked most often about this grinder.
Weigh the beans, check that the tab under the hopper is closed and pour them in. Rest the anti-chaff funnel on the cup and bring them up to the grinder until they touch the front plate, start with the side button and only then open the tab. Once the last bean has dropped, close the tab again; when no more coffee comes out of the spout press the Blow Up on the hopper, still with the tab closed, to clean the chamber, then switch off with the side button.
It is not a grinder for a bar or café: every dose is weighed and ground on its own, it is a small ritual.
Turn the King Size dial clockwise for a finer grind, anticlockwise for a coarser one. The adjustment is stepless: go gradually and grind a little coffee every 2 notches at most. The rev counter on the dial makes it easier to switch between brewing methods.
When you go finer, do it with the motor running. The Single Dose Pro's motor is designed for home use and is less powerful than a professional grinder's: if you turn the dial a full turn with the motor stopped, the grinder can jam. If it happens, write to us before sending it for repair.
It comes with 65 mm Pure Diamond flat burrs, with Diamond Inside technology and a blind upper burr, in the design Eureka calls Italian Espresso Taste, made for espresso.
The Pro is compatible with the Black Diamond range, sold separately in four versions: Espresso Specialty, Italian Espresso Taste, Brew Special for filter and All Purpose for espresso and filter.
