The Eureka Mignon Zero from the Florentine mill manufacturer Eureka is a coffee grinder specially designed for single dosing, which is suitable for both espresso and filter coffee. Single dosing is the term used to grind coffee beans individually. This alternative workflow has become established among home baristas in recent years. Unlike the conventional approach, with single dosing, the amount of beans required for the desired preparation is first weighed. These beans are then ground completely. With single dosing, the coffee beans are not stored in a large container in the grinder, but are ideally packed in an airtight manner and retain their aroma. In addition to the freshness of the coffee or espresso beans, single dosing is very wasteful. This is because more coffee beans are never ground than needed. This means that there is no need to dispose of any leftovers from the grinder. Changes in the degree of grinding are also immediately apparent, as no ground material from the last grinding process is mixed in. What is almost a given for Eureka is that the grinding level can be adjusted continuously and precisely.

Workflow-oriented features

In order to operate a sensible single dosing, a coffee grinder should meet one criterion above all: minimal dead space. Dead space is the amount of ground coffee that remains inside a coffee grinder (in the grinding chamber, in the ejector or in other spaces). The smaller the dead space, the better the grinder is suited to grinding everything completely and the less a grinding process is contaminated by old ground coffee. You might have guessed: The zero in the name of the Eureka Mignon Zero refers to this dead space - it is practically zero. To achieve this, an accordion-like collar is installed under the lid of the filling funnel, so that the grinder is blown out by repeatedly pressing the lid and even the smallest residues leave the grinder. The stainless steel dosing cup supplied is also particularly practical for the workflow. After the beans have been weighed in it, it can be hung where other models from the Mignon series have a portafilter mount. After the grinding process, the cup is ideal for pouring the coffee grounds into the portafilter or coffee filter.

The slightly different Eureka Mignon

The straight-line design of the housing immediately reveals that this coffee grinder is a Eureka Mignon. Unlike its siblings, the Eureka Zero has more rounded shapes with the bean hopper and the measuring cup. The chrome housing in combination with the chrome-plated ejector is also pleasing. A powerful 310 watt motor inside ensures good performance, driving the 55 mm hardened steel grinding discs at 1350 revolutions per minute. Despite all its power, the Mignon Zero is surprisingly quiet thanks to Eureka's Silent technology.
