Description
Grind Only What You Brew
Stale, retained grounds sitting in a hopper overnight are a quiet flavour thief in most Indian cafés and home bars. The Eureka Mignon Zero solves this with a true single-dose workflow, grinding exactly 45 g at a time with near-zero retention between shots.
Florentine Precision, Since 1920
Eureka has machined burrs and grinder bodies in Florence for over a century. The Mignon Zero carries that lineage forward as a compact, direct-drive grinder purpose-built for espresso, with enough range for filter and pour-over doses too.

Engineered For Consistency
- 55 mm hardened steel flat burrs for uniform particle size
- ACE System prevents clumping and reduces static in the dose
- Stepless micrometric adjustment for infinite grind settings
- Silent Technology cuts operating noise by roughly 20 dB
Every Feature Has A Job
Direct-Drive Motor
310 W direct-drive motor spins the 55 mm burrs at 1350 RPM, cutting grind time without sacrificing consistency.
Blow-Up Cleaning System
A built-in air system clears residual grounds from the chamber after each dose, keeping flavour clean shot to shot.
High-Speed Maintenance
The burr carrier is accessible without tools, so cleaning and burr checks take minutes, not a service appointment.
Extra Comfort Knob
An oversized adjustment knob makes fine-tuning grind size tactile and precise, even mid-service.
Adjustable Fork
The dosing fork adapts to portafilters of different diameters, so it isn’t locked to one machine brand.
45 g Single-Dose Hopper
Load only what you’ll grind. No standing beans, no stale coffee waiting at the top of the burrs.

Frequently Asked
What does single-dose grinding mean?
You load only the coffee you’re about to grind, typically the amount for one or two shots, instead of keeping a standing hopper of beans. The Mignon Zero’s 45 g hopper and low retention design are built for this workflow.
How much coffee can I grind in one go?
The hopper holds up to 45 g. It’s designed to be refilled per session rather than kept topped up, which keeps beans fresher at the point of grinding.
What are the burrs made from, and can they be replaced?
The Mignon Zero uses 55 mm hardened steel flat burrs, accessed through a high-speed maintenance mechanism that doesn’t require tools to open the burr chamber.
How noisy is it compared to a standard grinder?
Eureka’s Silent Technology reduces operating noise by approximately 20 dB versus a conventional grinder of similar power, making it suitable for open-plan cafĂ©s and home kitchens alike.
Will the dosing cup fit my portafilter?
The included stainless steel dosing cup is 58 mm compatible, and the adjustable fork accommodates portafilters of varying diameters.
Built For The Counter That Cares About Every Dose
The Eureka Mignon Zero is for baristas and home brewers who measure consistency in grams, not guesswork â a compact, direct-drive single-dose grinder equally at home on a busy Indian cafĂ© counter or a considered home espresso setup.
