The Mignon Zero 65 Speedy is the espresso-focused version of Eureka’s single-dose Zero 65 line. It uses 65 mm flat hardened steel burrs (a step up from the 55 mm burrs on the standard Mignon Zero) driven by a 320 W direct-drive motor at 1650 RPM, which is what produces the “Speedy” grind rate of 2.3 to 2.8 grams per second for espresso. A 45 g blow-up hopper with an anti-popcorning system and a silicone bellows lets you load a single dose, grind, and clear the chamber so leftover coffee doesn’t end up in the next shot.

Speedy vs. All Purpose: which Zero 65 to pick

Eureka sells the Zero 65 in two variants with the same 65 mm burr size but different burr geometries and motor speeds. The Speedy uses an espresso-optimised burr profile and runs at 1650 RPM for fast espresso doses. The All Purpose (AP) uses a wider-range burr geometry and runs at 1350 RPM, trading some espresso speed for better consistency at filter and French press grinds. If you almost exclusively pull espresso, the Speedy is the more focused tool. If you regularly switch between espresso and pour-over or French press, the AP is the more flexible choice.

Stepless adjustment and low retention

Grind size is set with Eureka’s patented stepless micrometric system, which moves the lower burr and gives infinite adjustment points rather than fixed clicks. Combined with the King Size dial, this makes small dial-in changes practical. Retention is genuinely low when you use the b
