About the Brand
Eureka has been designing and building coffee grinders in Florence, Italy since 1920, founded by Aurelio Conti. More than a century on, the company is still based in Sesto Fiorentino and hand-assembles its grinders in the same Florentine factory, having grown into one of the most recognised names in espresso grinding worldwide — trusted by cafés and roasters for pairing precise Italian engineering with genuine artisanal craft.
The Product
The Eureka Oro Mignon Single Dose Espresso Grinder is Eureka's answer to the single-dose category, built on the same platform as the popular Mignon XL 65 but tilted 15 degrees and fitted with a bellows-equipped single-dose hopper. It's part of Eureka's premium Oro range, cutting into 65mm Diamond-coated burrs to grind only what you load — nothing more. This is Eureka's commercial-grade engineering, redirected entirely at the single-dose home barista.
Key Features
65mm Diamond Burrs (Precision Cutting Edge)
Eureka's patented Diamond-coated 65mm flat burrs hold their edge longer and cut consistently at 2.3–2.8g/s for espresso.
15° Tilted Grind Chamber (Gravity-Assisted Output)
The whole grinder is angled 15 degrees, so gravity does more of the work moving grounds out of the chamber and into your dosing cup.
ELR System (Extremely Low Retention)
An extremely-low-retention design keeps almost nothing behind between doses, so the coffee you loaded is the coffee you get.
Mignon Blow Up (Bellows Clearing)
A bellows mechanism pushes through any grounds left in the chute after grinding, taking output close to 100% of what you loaded.
ACE System (Anti-Clump & Anti-Static)
Eureka's anti-clump, anti-static design keeps grounds falling freely instead of sticking to the chute or clumping in the cup.
Single Dose Hopper & Dosing Cup Included (Ready Out of the Box)
A single-dose hopper and dosing cup ship with the grinder, so you can start single-dosing immediately without sourcing separate accessories.
Stepless Micrometric Regulation System (Precise Dial-In)
Eureka's patented stepless system lets you fine-tune grind size in small increments rather than jumping between fixed settings.
Who It's Built For
You've decided single dosing is non-negotiable and you want the Eureka build quality to back it up. The Oro Mignon Single Dose gives you Diamond-burr precision, a tilted chamber and Eureka's ELR retention system in a grinder built specifically around loading only what you're about to grind. It's built for the home barista chasing zero carryover and maximum flavour clarity between coffees — every dose, exactly what you put in.
