Description
Zero waste. Zero noise. Zero complications.
The Eureka Mignon Zero 55S is a compact single-dose coffee grinder designed for home baristas who want freshly ground coffee, precise adjustment and minimal retention. Its 55 mm flat hardened-steel burrs, patented stepless micrometric adjustment and quiet operation provide the control required to dial in espresso with confidence.
Add only the coffee needed for each preparation, grind it fresh and use the integrated Blow Up System to help clear remaining grounds from the grinding chamber. The result is a clean, repeatable workflow that makes it easier to switch coffees without leaving old grounds behind.
Single-Dose Workflow
Weigh your beans before grinding and prepare one dose at a time. This workflow preserves freshness, makes it easier to change coffees and eliminates the need to leave beans sitting in a traditional hopper.
55 mm Flat Hardened-Steel Burrs
The 55 mm flat burr set delivers uniform grounds and dependable performance for espresso while remaining versatile enough for moka pot, drip and other brewing methods.
Anti-Retention and Blow Up Systems
Eureka designed the Zero 55S to minimize the amount of coffee retained inside the grinder. After grinding, press the bellows to help move remaining grounds through the chute and into the dosing cup.
Patented Stepless Micrometric Adjustment
Eureka's stepless adjustment system gives you precise control over grind size without locking you into preset steps. Fine adjustments make it easier to dial in different coffees, doses and espresso recipes.
King-Size Adjustment Dial
The enlarged adjustment dial improves control and visibility, allowing small grind changes to be made more comfortably and accurately.
Silent Technology
Eureka's noise-reducing design helps keep grinding quieter, making the Zero 55S well suited to kitchens, condos, offices and early-morning espresso routines.
ACE Anti-Clump and Anti-Static System
The ACE System helps reduce clumping and static while promoting a cleaner flow of ground coffee from the chute into the dosing cup.
Dosing Cup Holder with Easy Switch
A simple metal lever activates the grinder while the adjustable holder supports the included dosing cup, creating a smooth and practical single-dose workflow.
