Overview
The Eureka Mignon Crono is the most affordable entry point to the Mignon grinder family, featuring 50mm flat burrs that still deliver respectable espresso grinding performance. While the smaller burrs mean slightly less uniformity compared to the 55mm models above it, the Crono still outperforms most competitors in its price range thanks to Eureka engineering and build quality. The same quiet motor and compact footprint make it a great choice for apartment dwellers and anyone upgrading from a blade or cheap burr grinder. The Crono proves that you do not need to spend a fortune to get quality Italian-made espresso grinding.
The Eureka Mignon Crono features a 50mm flat burr set, crafted from steel. The burrs spin at 1350 RPM, offering fast grinding for high-volume use. Grind retention is approximately 1.0g, which is impressively low and suitable for single-dose workflows.
At $229, the Eureka Mignon Crono is aimed at home baristas seeking a solid grinder without a premium price tag. Key workflow features include stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.
The Eureka Mignon Crono is weighing 5.0 kg, manufactured in Italy, powered by a 260W motor. Its footprint measures 120 x 180 x 320 mm (W×D×H).

Our Verdict
The Eureka Mignon Crono uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. At under $500, it's an accessible entry into flat burr grinding. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions

Yes, the Eureka Mignon Crono is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Why choose flat burrs in the Eureka Mignon Crono?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Eureka Mignon Crono?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
