The Blind Upper Burr — The Standout Upgrade

The most significant engineering change in the Pro is the Blind Upper Burr. Unlike the original, which had screw holes in the upper burr carrier that trapped fine coffee particles, the Pro's upper burr is completely smooth. This eliminates a hidden source of retention and improves grind uniformity, resulting in a narrower, more consistent particle distribution — and a noticeably cleaner cup.

Burrs Built for Espresso, Ready for Filter

The 65mm Pure Diamond flat burrs use Eureka's patented crystal structure process — harder and sharper than standard steel burrs — optimized to deliver exceptional clarity and consistency for espresso. And when you want to explore filter brewing, the same burrs handle it with ease, making the Single Dose Pro a genuinely versatile grinder for any home setup.

Retention: The Problem, Finally Solved

The original Mignon Single Dose was already known for low retention — but Eureka went further. The Pro features a completely redesigned ZERO-retention grind chamber that reduces residual coffee by up to 70% compared to its predecessor. Combined with the Blow Up System, which uses a burst of air to clear the grind path after each dose, you get virtually 100% fresh coffee in every single shot — no stale grounds carried over from the last grind.

Dial In Once, Repeat Every Time

The original Single Dose had a small, hard-to-read adjustment dial that made it difficult to track your grind setting. The Pro replaces it with a King-Size Dial featuring a built-in rotation counter, so you always know exactly where you are and can return to your favorite setting after switching between coffees or brew methods — without guesswork.

A Motor You Can Trust for a Decade

The Pro's direct drive motor runs at 1,650 RPM — slow enough to protect aroma and prevent heat buildup, powerful enough at 320W to handle any roast level consistently. Eureka backs it with a 10-year motor warranty, one of the longest guarantees in its class, reflecting the confidence they have in the Pro's long-term reliability.

Designed for the Single Dose Ritual

The 15° inclined body makes it natural to load a single weighed dose directly into the hopper without spillage. The anti-popcorning system prevents light-roast beans from bouncing out, and the anti-chaff funnel keeps your counter clean. The 45g hopper capacity is intentionally minimal — this grinder is built around the single dose workflow, not bulk grinding.
