Designed for home baristas who value precision, consistency, and quiet operation, the Eureka Mignon Zero 55S combines Eureka’s proven grinding technology with a workflow tailored for single dosing and espresso preparation. Compact yet capable, the Zero 55S delivers exceptional grind quality through 55mm hardened steel flat burrs, stepless micrometric adjustment, low-retention grinding, and remarkably quiet performance. Precision Grinding with 55mm Flat Burrs At the heart of the Zero 55S are 55mm hardened steel flat burrs engineered to produce uniform particle distribution for balanced and repeatable extractions. The flat burr design creates consistent grounds with excellent clarity and sweetness in the cup, making it ideal for espresso while remaining versatile enough for filter coffee and other brewing methods. The hardened steel construction ensures long-lasting durability and reliable performance over years of daily use. Stepless Micrometric Adjustment Eureka’s patented stepless micrometric adjustment system allows precise control over grind size with infinite adjustment points between coarse and fine settings. Whether dialing in espresso or making subtle corrections for different coffees and roast levels, the oversized King Size Grind Dial provides smooth, accurate adjustments with excellent tactile feedback. Unlike traditional designs, Eureka’s system adjusts the lower burr, allowing maintenance and burr cleaning without losing your grind setting. Low Retention Single-Dose Workflow Built with single dosing in mind, the Zero 55S incorporates Eureka’s Blow Up System to minimize grind retention inside the chamber and chute. By actively clearing residual grounds after each dose, the grinder ensures fresher coffee, improved consistency, and more accurate dosing with minimal waste. This low-retention design is especially beneficial when switching between coffees or adjusting grind settings frequently. ACE System for Cleaner Grinding Eureka’s ACE (Anti-Clumps & Electrostaticity) System reduces static buildup and prevents clumping during grinding. Grounds flow smoothly into the dosing cup with less mess, better distribution, and improved consistency shot after shot. The result is a cleaner countertop and a more streamlined espresso workflow. Quiet, Home-Friendly Operation Thanks to Eureka’s Silent Technology and anti-vibration design, the Zero 55S operates at approximately 51 dB — dramatically quieter than many traditional espresso grinders. The die-cast aluminum body helps absorb vibration and reduce resonance, making it ideal for early mornings or shared living spaces. Simple and Intuitive Workflow The integrated dosing cup holder and rear-mounted activation lever create a natural, hands-on grinding experience. Simply place the cup, activate the lever, and grind directly into the cup with precise manual control — perfect for single dosing and weighing beans before grinding. Compact Design with Premium Construction With its durable die-cast aluminum body and compact Mignon footprint, the Zero 55S fits comfortably on home countertops while delivering commercial-inspired grinding performance. The 150g hopper capacity suits daily home use while maintaining a clean, minimalist aesthetic. Combining precision, quiet operation, low retention, and intuitive usability, the Eureka Mignon Zero 55S is an excellent choice for espresso enthusiasts seeking professional-level results in a compact home grinder.
