Coffee grinder Eureka Mignon Zero with 55mm flat burrs, stepless micrometric adjustment

Eureka Mignon Zero with 55mm flat burrs is a compact electric coffee grinder designed for precise and consistent grinding at home or in small professional environments. The stepless micrometric adjustment allows fine tuning of grind size from espresso to coarser settings suitable for filter methods. Its doserless configuration and small footprint make it practical for countertops while delivering stable particle distribution thanks to 55 mm flat steel burrs and a motor optimized for low RPM performance.

Advantages

The combination of 55 mm flat burrs and stepless micrometric adjustment gives accurate and repeatable control over grind size without discrete steps, supporting a wide range of brewing methods. The doserless design reduces retention and allows direct dosing into portafilters or dosing cups, while the compact housing occupies minimal counter space. The grinder is engineered to minimize heat transfer and preserve coffee aroma with a motor speed appropriate for consistent grinding performance.

Suitable for

• Grinding for espresso preparation at home or in small cafés
• Preparing medium-coarse grinds for pour-over and drip filter methods
• Users seeking precise micrometric control over particle size
• Environments with limited counter space that require a compact grinder

Key specifications

• Burr type: 55 mm flat steel burrs
• Adjustment: Stepless micrometric grind adjustment
• Design: Doserless (direct dosing into portafilter or container)
• Motor behaviour: Low-RPM operation for consistent particle distribution
• Form factor: Compact footprint suitable for home and small professional use

How to use

Place the grinder on a stable, level surface and plug it in according to the appliance instructions. Adjust the micrometric knob to the desired grind setting, starting from a coarser position and moving finer in small increments until the correct extraction is achieved. Place your portafilter, dosing cup, or container under the spout and activate grinding. For consistent results, weigh doses and grind only the amount needed for immediate extraction.

Usage recommendations

To maintain consistent performance, clean the burrs and grinding chamber regularly following manufacturer guidance and avoid grinding oily or flavored beans that may increase residue. Allow short pauses when grinding larger quantities to prevent heat build-up. Use the stepless adjustment to fine-tune for roast profile and brew method, and calibrate grind size by testing small adjustments and tasting the extracted coffee.
