Mahlkönig EK Omnia - The future of coffee grinding

With the EK Omnia, Mahlkönig redefines the standard of professional coffee grinding. Based on the iconic EK43, this grinder combines decades of experience with state-of-the-art technology - for unparalleled precision, speed and reproducibility. The EK Omnia is designed to deliver consistent results at the highest level in any environment - whether roastery, specialty café or laboratory.

The next step in the evolution of the EK series

While the EK43 set the standard for homogeneous particle distribution, the EK Omnia goes one step further: it combines legendary grinding quality with intelligent, digital features and takes workflow and consistency to a whole new level. The intuitive touch display, a memory-based library mode and an automatic grinding disk positioning system ensure that every grinding process is precise, reproducible and fast - even with changing personnel or high throughput rates.

Intelligent grinding with library mode

The new library mode allows you to save up to ten individual grinding recipes - including bean type, target quantity and grinding degree in micrometers. Simply select your recipe and the EK Omnia automatically adjusts the grinding disk distance to the saved parameters. This gives you exactly reproducible results every time - whether filter, espresso or cupping.

Precision you can see and taste

The grinding degree is no longer estimated using analog scales, but recorded digitally - with real-time measurement of the grinding disc distance. You can fine-tune the distance in micrometers via the large, front-facing touch display or simply adjust it using the dial. The 98 mm hard cast steel grinding discs made in Germany ensure a consistent, aroma-preserving grinding result - dose for dose.

Optimized workflow for professionals

The EK Omnia is consistently designed for efficiency and durability. The powerful BLDC motor operates almost silently and with low vibration, while the heat dissipation system with cooling fins ensures stability even during continuous operation. The magnetically attached portafilter holder allows hands-free operation and can be replaced with the smooth front plate if required. This allows the grinder to be perfectly adapted to different application scenarios.

Three operating modes for maximum flexibility

  • Classic mode: Manual control via grinding time
  • Time mode: Time-based dosing for espresso workflows
  • Library mode: Storage of recipes including automatic grind setting

Design meets function

Inspired by the legendary EK43, the EK Omnia has a modern, clear design with illuminated start/stop ring, removable spout, magnetic drip tray and integrated LED spotlight. It is available in matt black or matt white fine structure and has been awarded the iF Design Award 2024 and the UX Design Award | Gold.

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?

Yes, of course, you are welcome to come by and look at our products by appointment. We would be happy to advise you personally. The best thing to do is to send us an email with a few suggested appointment times.

We are located 5 minutes from the motorway between Stuttgart and Lake Constance on the edge of the Black Forest.

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.

¿Pueden realizar una calibración de offset en mi máquina de portafiltro?

Existen varios argumentos en contra de una calibración de compensación en las máquinas de portafiltro Lelit, especialmente en modelos como la Lelit Bianca. Estos se refieren principalmente a la complejidad y las limitaciones de la compensación como única solución para problemas de temperatura:

  1. Fluctuaciones de temperatura e inestabilidad. La compensación considera una diferencia constante entre la temperatura de la caldera y la temperatura de preparación. Sin embargo, en la práctica pueden ocurrir fluctuaciones de temperatura, por ejemplo, debido a tiempos de espera prolongados o preparación continua. Esto hace que la temperatura de preparación real no siempre sea predecible con precisión.
  2. Dependencia de las condiciones ambientales. Factores como la temperatura ambiente, la humedad y el estado de la máquina (por ejemplo, el tiempo de calentamiento) afectan significativamente la temperatura de preparación. Una compensación fija no puede equilibrar dinámicamente estas variables, lo que puede llevar a resultados inexactos.
  3. Pérdida de calor durante los tiempos de espera. Después de pausas prolongadas, el grupo de preparación se enfría y la máquina necesita tiempo para volver a la temperatura deseada. Una compensación correctamente ajustada no puede compensar esto, por lo que son necesarias medidas adicionales como un "Cooling Flush".
  4. Desajustes de fábrica. En algunos modelos de Lelit se ha encontrado que la compensación de fábrica a menudo está configurada de manera inexacta (por ejemplo, de 4 a 8 grados demasiado baja en la Lelit Bianca). Esto requiere una recalibración manual por parte de personal especializado, lo cual puede ser complicado para los usuarios finales.
  5. Malentendidos en la aplicación. Muchos usuarios están confundidos por la información contradictoria sobre la configuración de la compensación, lo que puede llevar a ajustes incorrectos. Por ejemplo, a menudo se espera que la compensación por sí sola resuelva todos los problemas de temperatura, aunque solo es parte de un sistema más complejo.

Conclusión
La calibración de compensación es una herramienta útil, pero no debe considerarse de forma aislada. Una combinación de control PID preciso, mantenimiento regular y técnicas adaptadas (por ejemplo, "spülshots") es necesaria para lograr resultados óptimos de preparación.
