Eureka Mignon Single Dose Pro Espresso Coffee Grinder

Eureka Mignon Single Dose Pro Espresso Coffee Grinder

Launched around late 2024 / early 2025, the Eureka Mignon Single Dose Pro is an upgraded version of the original Single Dose, refining its workflow and performance. It features 65mm Diamond Inside burrs with a blind upper burr design, a zero-retention grind chamber, and Eureka’s Blow Up system with a 15° inclined body to minimize retention and improve consistency. A larger King Size dial with rotation counter enhances grind adjustment precision, while Silent Technology keeps operation quiet. Designed for single dosing, it excels in environments where users frequently switch coffees and demand accuracy—such as enthusiast setups or light commercial use. Building on the original Mignon Single Dose platform, the Pro delivers faster grinding, improved usability, and more consistent results with less waste.

Eureka’s ELR (Extremely Low Retention) System aims to reduce the amount of coffee ground retention as much as possible. As you grind, there is a constant stream of ground coffee that flows from the burrs to the coffee chute down into your portafilter (dosing cup). Once you stop, that stream almost stops in its tracks. Any leftover coffee will negatively affect your next espresso shot. Eureka designed the Mignon Single Dose Pro to siginificantly reduce that ground coffee buildup at any point inside the grinder. As a result, you will get fresher coffee, precise dosing, and cleaner work flow.

The result?

“Diamond Inside” Flat Burrs

Eureka’s “Diamond Inside” burrs are engineered for long-lasting sharpness and consistent grind quality over time. Thanks to a specialized hardening process, these burrs resist wear far better than standard steel burrs, maintaining their cutting precision through heavy use. The result is more uniform particle size, which leads to better flavor clarity and balance in the cup. For the user, that means fewer adjustments, more reliable performance, and a grinder that stays dialed in longer between maintenance or replacements.

Stepless Grinding Adjustment

The stepless adjustment system gives you complete control over grind size, allowing for micro-adjustments rather than being locked into preset steps. This is especially important for espresso, where even small changes can dramatically impact extraction time and taste. With stepless control, you can fine-tune your grind to match different beans, roast levels, and environmental conditions. The benefit is greater precision and repeatability—helping you consistently hit the sweet spot for balanced, flavorful shots.

Low Profile Bean Hopper

The low profile hopper is designed with both practicality and workflow in mind. Its compact height makes it easier to fit the grinder under kitchen cabinets, while also encouraging users to load only the beans they plan to use. This supports fresher grinding and aligns well with single dosing practices. By minimizing the amount of beans stored in the hopper, you reduce exposure to air and preserve flavor. It’s a small design choice that contributes to better coffee and a more streamlined setup.

Dosing Cup

The included dosing cup simplifies your workflow by allowing you to grind directly into a measured container before transferring grounds to your portafilter. This reduces mess, improves consistency, and makes it easier to manage your coffee dose with precision. It’s especially useful for single dosing, helping you maintain control over each shot without relying on timed grinding. The result is a cleaner, more efficient routine that supports repeatable, high-quality espresso.

Espresso Coffee Grinder Warnings:

• Roast Profiles: Espresso grinders sold by 1st-line Equipment, unless specifically indicated on the grinder page, are manufactured for coffee beans that have Italian or espresso roast profiles. Lighter roasted coffee beans may clog the grinder or not grind fine enough. Darker roasted coffee beans, such as French roasted or oily coffee beans, may clog the grinding chamber and/or the grinder chute where the ground coffee exits.
• Changing grind settings: It is very important to only change grind settings when the unit is powered on and the burrs are in motion. If you do not do this, the burrs will ‘gunk’ up and render the grinder to only produce very coarse grinds or no grinds at all. To remedy this, you will have to open up the grinder to get access to the grinding burrs. This issue will be considered operator error for lack of following directions, and not be classified as a defective grinder.
• Electrical cord: For most grinders, the cord is placed between the packaging (foam or cardboard) and the underside body of the grinder. During shipping, it is normal for a bend or insignificant blemish/slice to damage the cord.
• Finding coffee grinds in a new grinder: Most manufacturers test their grinders with coffee beans before they leave their facility. Unfortunately, they are not always able to get every trace of coffee out of the grinders after testing. As a result, you may find coffee beans or grinds inside your grinder, or there may be grinds in the packaging.
• Static issues: There are static issues with all grinders, even the highest-quality models. We firmly believe that the static comes from the coffee beans. If you are having static problems with your coffee grinder, try using a different blend of beans.
• Electrical: To avoid electrical damage (which is not considered a manufacturer's defect), please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. A surge without protection can damage a grinder at the power switch, the capacitor, the motor, or the wiring.
• Burr cleaning: For routine maintenance of the grinding burrs, we recommend using grinder cleaning agents. We do not recommend any removal of the burrs or the burr carrier for cleaning (unless necessary) as re-assembly can cause damage. If the grinder chamber is dis-assembled, the warranty is voided for any damages that result. It is important to always remove all coffee grinds from the threads of the burr carrier and the grinding chamber.
• Replacing burrs: NEVER use a flat head screwdriver and hammer to wedge UNDER the burrs for removal. This could badly damage your grinder.
