Eureka Oro Mignon XL

What it does well

Speed comes from the burrs and motor. Eureka lists 1,650 rpm. Seattle Coffee Gear says the burrs "make quick work of coffee beans," and Home Grounds cites 2.3 to 2.8 g a second.

Eureka calls the burrs Pure Diamond and describes a patented cryogenic treatment it calls Diamond Inside. It says the treatment improves wear resistance.

It stays quiet. Seattle Coffee Gear rates it comparable to the Specialità and calls it "one of the quietest grinders you can get." Home Grounds says it keeps noise under 70 dB despite the bigger motor.

The controls are familiar. Seattle Coffee Gear notes the touchscreen timer, single and double doses and fork carry over from the Specialità. Eureka adds an extra-dose function and a dose counter.

Adjustment is stepless and acts on the bottom burr, so cleaning does not lose your setting. Home Grounds reports dose-to-dose retention varying by only 0.2 to 0.3 g.

Home Grounds also likes the included mat kit. Eureka lists a washable silicone mat, a tamping station and a cleaning brush in the box.

Where it falls short

It is built for espresso. Home Grounds calls it "primarily an espresso-focused grinder" and lists coarse grinds as a weakness. It found filter grind distribution less impressive.

It is bigger than other Mignons. Home Grounds says it takes more space than other Eureka grinders. Coffee Blog notes it is 1.6 kg heavier.

Seattle Coffee Gear's one caveat is the learning curve. It says stepless adjustment "can take some time to get the hang of" if you are new to it.

None of the reviews here measured total retention for single dosing. If you plan to weigh every dose and empty the grinder, look at a dedicated single-dose design.

Who should buy it, and who shouldn't

Buy it if you make espresso daily from a full hopper and want a quiet, quick grinder that fits under cabinets. Seattle Coffee Gear says its hopper is low enough to fit under cabinets.

Skip it if you mainly brew filter. Skip it too if the Specialità's 55 mm burrs would satisfy you, since Home Grounds found little difference in results.

How it compares

The Eureka Mignon Specialità is the direct step down. Home Grounds says it costs about half as much and performs similarly. Its burrs are 55 mm rather than 65 mm.

The Eureka Atom 75 goes further, with 75 mm burrs and a 900 W motor, per Eureka. It is much taller and heavier, and Home Grounds notes it costs more.

The Niche Zero is a conical single-dosing grinder. Home Grounds describes it as built for a simpler workflow with fewer adjustments. For a flat-burr single doser, see DF64 Gen 2 vs Oro Mignon XL.

Owning it

Cleaning follows the Mignon pattern. Because the bottom burr sets the grind, you can remove the top burr and refit it without losing your setting. Our guide to cleaning a burr grinder walks through it.

Eureka's burr treatment is meant to extend burr life. When the burrs do wear, see how to replace grinder burrs.

Eureka lists a metal outlet chute and a rubber-coated universal fork. Use the settings chart on this page as a starting point, then dial in the grinder on your own coffee.
