The short answer
Choose the Eureka Mignon Specialita if you drink one coffee daily and want a quiet grinder you fill and forget. Choose the DF64 Gen 2 if you switch beans often, want near-zero retention, and like the option of swapping burrs later.

1. Choose this for a hopper and quiet
Eureka Mignon Specialita
Upper-mid tier · An Italian 55 mm flat-burr espresso grinder with stepless micrometric adjustment.
55 mm Italian flat burrs, micrometric stepless adjustment and timed dosing.
The Specialita uses 55 mm flat hardened-steel burrs made in Italy, with stepless micrometric adjustment on the lower burr. Eureka publishes output of up to 1.8 g per second - roughly ten seconds for an 18 g double - and dosing is digital and timed, adjustable in tenths of a second.
Its micrometric mechanism can be taken apart for cleaning and reassembled without losing the setting, and it is built with sound insulation, which makes it one of the quieter electric espresso grinders.
It is hopper-fed by design: fill it and grind on demand. Single dosing it is a workaround, and its retention is not in the sub-0.1 g class of purpose-built single-dose grinders.
For one coffee used every day, that hopper is the convenience.
Specification
- Burrs
- 55 mm flat hardened steel, made in Italy
- Adjustment
- Stepless micrometric on the lower burr
- Output
- Up to 1.8 g per second
- Dosing
- Digital timed, adjustable in tenths of a second
What it does well
- Genuinely quiet - the sound insulation is not marketing
- Micrometric adjustment holds its setting through a strip-down clean
- Fast enough that an 18 g dose is a ten-second job
Where it gives ground
- Hopper-fed by design; single dosing it is a workaround
- No weight-based dosing
- Espresso-focused - the coarse end is not its strength
Skip it if
Skip it if you keep several bags open and switch often. A single-dose grinder suits that - see the full review.
2. Choose this for single dosing
DF64 Gen 2
Upper-mid tier · The 64 mm flat-burr single-dose grinder that made the format mainstream at home.
64 mm flat burrs, retention under 0.1 g and swappable burr sets.
The DF64 Gen 2 uses 64 mm stainless flat burrs with stepless adjustment, retention listed at under 0.1 g, a 250 W motor at 1400 rpm and a 50 g hopper.
Sub-0.1 g retention means switching coffees costs nothing: weigh a dose, grind it, and nothing stale is left behind.
Sixty-four millimeters against fifty-five is a real difference in cutting area, and aftermarket burr sets let you change the grinder's character over time.
The costs are size - 30 cm tall and 6.8 kg - more noise, and roughly twenty extra seconds per brew for its bellows and dosing cup.
Specification
- Burrs
- 64 mm flat stainless; aftermarket sets available
- Adjustment
- Stepless
- Retention
- Under 0.1 g
- Motor
- 250 W, 1400 rpm at 110/120 V
- Hopper
- 50 g
- Size
- 13 cm W x 22.5 cm D x 30 cm H, 6.8 kg
What it does well
- 64 mm flats are the burr size the espresso world benchmarks against
- Burrs are swappable, so the grinder can be re-tuned rather than replaced
- Ionizer probes in the chute keep static manageable
Where it gives ground
- Heavy and tall for a home counter
- Stepless adjustment with no detents demands note-keeping
- Version numbering across sellers is genuinely confusing
Skip it if
Skip it if the single-dose ritual is what you are trying to avoid - see the DF64 review.
Your routine decides
A hopper grinder suits a household that drinks one coffee and wants to press a button. A single-dose grinder suits someone who switches coffees, weighs every dose, and wants nothing stale sitting in the grinder.
Both are capable stepless espresso grinders. The daily workflow is the difference you will notice every morning - see single-dose grinders.
