The diameter of the grinding burrs determines how many revolutions are needed for the same amount of coffee. Larger burrs need fewer revolutions, the grind warms up less, and heat in the grind reduces aroma.

Who the Eureka Mignon Libra 65 All Purpose 16CR + 5 Jahre Garantie is made for
Grind size decides before the machine even starts.
The beans sit in the hopper, ground on demand. This is the faster way when the same variety is always running.
- 01 No scale next to itThe grinder weighs the dose itself and stops at the set weight. No reweighing, no residue in the portafilter, the same espresso in the morning as yesterday.
- 02 65 mm grinderSmaller discs require more revolutions for the same amount. For a few drinks a day that does not matter.
What's inside
The technology that matters for espresso.
flat, hardened steel
Flat burrs grind with two parallel rings and deliver a tight particle size distribution. You do not recognize dull burrs by appearance but by the fact that the shot runs faster than usual.
Scale dosing
The grinder weighs itself and grinds until the set amount is in the portafilter. That stays the same even when the bean changes or the bag gets emptier, where a time-based control would need readjusting.
Bean hopper 350 g
A large hopper means less frequent refilling. Bear in mind that beans age in it: anything that stays in the hopper for longer than a few days loses aroma, no matter how good the grinder is.
On-Demand
The beans sit in the hopper and are ground on demand. This is the faster way in everyday life, especially if the same coffee is used all the time. A full hopper, however, means that the beans at the bottom are exposed to the air for longer.
0.8 g per second
The grinder output indicates how much ground coffee comes out per second. For a single drink you hardly notice it, as extraction and milk determine the time. You only feel it when many drinks are made back to back.
Grind burrs approx. 500 kg
The manufacturer's guideline for how much coffee the burrs can handle before they should be replaced. You do not notice dull burrs by their appearance but because the extraction runs faster than usual at the same setting.
What matters for the grinder
What matters for this grinder.
The numbers from the data sheet, in the order that matters. A faster grinder does not grind better, it only grinds more.
65 mm
Large burrs, cooler grounds
The larger the burrs, the fewer revolutions are needed for the same amount of coffee. The grounds heat up less, and heat in the ground coffee costs aroma. Installed are flat hardened steel.
500 kg
How long the burrs last
Manufacturer specification for when the burrs should be replaced. Dull burrs are not noticeable by the grind appearance, but only by taste.
22,5 s
How long a dose takes
For 18 g of coffee, calculated from 0,8 g per second. For a single drink you hardly notice it: brewing and milk foam take longer than grinding.
13 × 20 cm
This is how much space it needs
These are 260 square centimeters of counter that are permanently occupied. At 43 cm height you need space above it for refilling.
All values come from the data sheet of this device. If a specification is missing, it is not listed here.
