Eureka Mignon Zero Espresso Grinder

The Mignon Zero is ideal for espresso enthusiasts who rotate between multiple coffees and want minimal waste. You weigh a single dose of beans, drop them into the open hopper, grind directly into the included 58mm stainless steel dosing cup, then use the rubber bellows to push out any remaining grounds. This keeps retention near zero and eliminates stale coffee sitting in a hopper. The stepless micrometric adjustment makes dialing in intuitive, even for intermediate home baristas stepping up from entry-level grinders.

The Zero is purpose-built for espresso. Its 55mm flat hardened stainless steel burrs and stepless micrometric adjustment excel at the fine, precise grind adjustments espresso demands, producing fluffy and remarkably uniform grounds. While you could coarsen it slightly for an AeroPress or Moka pot, it's not designed for pour-over or French press. If you need true all-rounder capability, consider a grinder with a broader grind range — the Zero's strength is espresso clarity and consistency at its price point.

After each session, use a grinder vacuum to remove residual fines from the burr chamber and dosing pathway — the bellows help, but vacuuming ensures nothing accumulates. Every few weeks, run Cafetto Grinder Cleaner tablets through the burrs to dissolve coffee oils that cause stale flavors and clumping. Always keep the Zero in a dry area of your kitchen; moisture can cause grounds to clump inside the burr chamber and degrade grind quality. These simple habits keep the 55mm flat burrs sharp and consistent.

The Zero is remarkably quiet thanks to Eureka's heavy noise insulation built into the Mignon casing. It's genuinely one of the quietest grinders at this price, making early-morning grinding far less intrusive. Despite the sound dampening, the 55mm flat burrs grind a single dose of espresso in roughly 10–12 seconds — quick enough that heat buildup isn't a concern. Clive's team uses these daily and can confirm the noise reduction is substantial without sacrificing grind speed or consistency.

The Zero sits as Clive's go-to affordable single-dose espresso grinder. It pairs naturally with machines like the LUCCA A53 Mini, Profitec Go, or Rancilio Silvia Pro X — setups where the barista values hands-on workflow without overspending on the grinder. Compared to Eureka's timed-dosing Mignon models, the Zero trades hopper convenience for a single-dose design that eliminates waste and simplifies coffee switching. If you need larger burrs or all-purpose grinding, Clive's team can help you explore options up the lineup.
