What is the difference between a grind-by-weight grinder and a time-based grinder?

A grind-by-weight grinder, such as the Eureka Mignon Libra, doses by weight instead of by time. This means that you can set your desired dose (in grams) and it will automatically stop once it doses that amount of coffee in your portafilter. With a time-based grinder, you have to adjust the timing to get the right dose which requires trial and error.

How do I adjust the portafilter holder on this machine?

The portafilter holder on this machine is adjustable so you can ensure waste-free grinding. To adjust it, simply loosen the screw and then move it up or down until your portafilter sits in there snugly.

How acurate is the dosing on this grinder?

When we tested this grinder against another scale, each of the five doses we tested were within 0.1 of our target – of them, three were right on point. This level of unprecedented in a grinder designed for home use.
