Perfect grind - thanks to "Grind by Weight"
With the Mignon Libra, there is no need for tedious adjustment of time and grind - the weight always remains constant! This means you always get the same amount of ground coffee, regardless of whether you change the grind for espresso or filter coffee. This makes adjustment much easier and improves the consistency of your coffee.
Silent Technology - pleasantly quiet grinding
Thanks to the advanced Silent Technology, the Eureka Mignon Libra grinds much more quietly than conventional espresso grinders. The quiet grinding noise makes it perfect for early mornings or for use in open-plan kitchens.
Innovative portafilter holder
The height-adjustable, rubberized portafilter holder enables hands-free grinding and is compatible with almost all portafilters. An integrated "funnel function" ensures that no coffee grounds fall out.

Frequently Asked Questions
I bought a new coffee grinder from Naturbohne and there are coffee residues in it.
Please note: Some manufacturers test their coffee grinders before shipping, which means that small coffee residues or bean residues can occasionally be found in the grinder. This procedure is used to test functionality and is considered a quality feature. Of course, we only sell new products - unless expressly stated otherwise.
Static charge – coffee grounds spray out from the side
With some coffee grinders, the ground coffee can become statically charged and spray out of the portafilter at the side. This means that not all of the ground coffee gets into the portafilter, which can lead to uneven extraction. Our recommendation: Use a dosing funnel to ensure that all of the ground coffee is precisely fed into the portafilter - for optimal espresso enjoyment.
What is dead space in coffee grinders?
Conventional coffee grinders often leave a so-called dead space in which coffee residues accumulate. These residues can not only affect the freshness, but also lead to old and fresh coffee grounds being mixed, which negatively affects the taste. In contrast, single dose grinders have a well-thought-out design that eliminates the dead space. Each portion is ground individually and precisely so that no residues are left behind - for a consistently pure and full-bodied coffee experience.
Which portafilter fits my espresso machine?
When choosing the right portafilter for your portafilter machine, it is important to know that each manufacturer develops its own brewing group - the most well-known is the Faema E61. However, this does not mean that any portafilter will fit without any problems. An incompatible portafilter can leak, which will have a direct negative impact on the quality of your espresso. We therefore recommend using either the portafilter originally supplied or one that is explicitly stated to be compatible with your machine. This will ensure that the pressure is optimally built up and the espresso is perfectly extracted.
Can I visit you or pick up the goods personally?

Important note, first use coffee grinders
Another little tip for the perfect start with your new mill:
You will get the best grinding result after you have ground about 1-2 kg of beans. It is best to use a few cheap beans so that the grinder can work optimally. And if you are wondering what you can do with the bean flour - it is perfect plant fertilizer! 🌿
It contains nitrogen, potassium, sulfur and phosphorus and is a real nutrient bomb for your plants.
Potete effettuare una calibrazione offset sulla mia macchina portafiltro?
Esistono alcuni argomenti contro la calibrazione offset per le macchine portafiltro Lelit, in particolare per i modelli come la Lelit Bianca. Questi argomenti riguardano principalmente la complessità e i limiti dell'offset come unica soluzione ai problemi di temperatura:
- fluttuazioni di temperatura e instabilità. L'offset tiene conto di una differenza costante tra la temperatura della caldaia e la temperatura di erogazione. Nella pratica, tuttavia, possono verificarsi fluttuazioni di temperatura, ad esempio a causa di tempi di sosta più lunghi o di una fermentazione continua. Di conseguenza, non è sempre possibile prevedere con precisione la temperatura effettiva della birra.
- Dipendenza dalle condizioni ambientali. Fattori come la temperatura ambiente, l'umidità e le condizioni della macchina (ad esempio, il tempo di riscaldamento) hanno un'influenza significativa sulla temperatura di fermentazione. Un offset fisso non può compensare dinamicamente queste variabili, il che può portare a risultati imprecisi.
- Perdita di calore durante le pause. Dopo le pause più lunghe, il gruppo di infusione si raffredda e la macchina ha bisogno di tempo per tornare alla temperatura desiderata. Un offset correttamente impostato non è in grado di compensare questo fenomeno, per cui sono necessarie misure aggiuntive come un "lavaggio di raffreddamento".
- Calibrazioni di fabbrica errate. Su alcuni modelli Lelit, è stato riscontrato che l'offset di fabbrica è spesso impostato in modo impreciso (ad esempio, 4-8 gradi troppo bassi su Lelit Bianca). Ciò richiede una ricalibrazione manuale da parte di personale specializzato, che può risultare complicata per gli utenti finali.
- Fraintendimenti nell'applicazione. Molti utenti sono confusi da informazioni contraddittorie sull'impostazione dell'offset, che possono portare a regolazioni errate. Ad esempio, spesso si pensa che l'offset da solo risolva tutti i problemi di temperatura, mentre è solo una parte di un sistema più complesso.
Conclusione
La calibrazione dell'offset è uno strumento utile, ma non deve essere considerata in modo isolato. Per ottenere risultati ottimali è necessaria una combinazione di controllo PID preciso, manutenzione regolare e tecniche personalizzate (ad esempio, colpi di risciacquo).
