This is a pre-order. Delivery will take place around the end of November. In addition, you will receive from us free of charge with your pre-order

Why the smartphone app makes all the difference

  • Convenience: manage grinds, doses and profiles conveniently via smartphone
  • Consistency: repeatable results thanks to saved recipes & digital scaling.
  • Transparency: usage statistics, history data and status messages at a glance.
  • Future-proof: Over-the-air updates for new functions & improvements.

Functions of the Mahlkönig Sync app

  • Grind-by-Sync control
    Real-time data exchange with compatible espresso machines (e.g. Xenia). The grinder automatically adjusts the grind to target extraction times - for consistent shots without readjustment.

  • Digital grind adjustment
    Electronic, reproducible fine adjustment in clear steps. Ideal for bean changes or seasonal roasts.

  • Recipe library
    Save and retrieve profiles for different beans & drinks (e.g. espresso, flat white) with grind, dose and target time.

  • Calibration & diagnosis
    Guided zero calibration, status checks and maintenance instructions for consistently precise results.

  • Cloud statistics
    Overview of averages, trends and the history of your purchases. Perfect for refining recipes.

  • OTA updates
    Automatic firmware updates via Wi-Fi - new features come directly to your grinder.

Synchronized with the espresso machine

In conjunction with a compatible machine (e.g. Xenia), the app analyzes extraction times in real time. If a shot deviates from the target, the E64 WS Home automatically corrects the grind. Result: shot-by-shot consistency without the guesswork.

Intuitive operating concept

  • OLED display on the grinder for direct control without a smartphone.
  • Electronic grind adjustment for reproducible settings.
  • Ball joint outlet - centered extraction directly into the portafilter.
  • Ambient light - adapt colors to setup & style via app.

Conclusion: The E64 WS Home is more than just a grinder - it is a networked system for precise, repeatable espresso quality. With app control, grind-by-sync and digital recipes, you can bring café consistency into your kitchen.

Note: A Wi-Fi connection is required for app functions. The availability of individual Sync features may vary depending on machine compatibility.

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.

Könnt ihr bei meiner Siebträgermaschine eine Offset Kalibrierung durchführen ?

Es gibt einige Argumente, die gegen eine Offset-Kalibrierung bei Lelit-Siebträgermaschinen sprechen, insbesondere bei Modellen wie der Lelit Bianca. Diese beziehen sich vor allem auf die Komplexität und die Limitierungen des Offsets als alleinige Lösung für Temperaturprobleme:

  1. Temperaturschwankungen und Instabilität. Der Offset berücksichtigt eine konstante Differenz zwischen Kesseltemperatur und Brühtemperatur. In der Praxis können jedoch Temperaturschwankungen auftreten, z. B. durch längere Standzeiten oder kontinuierliches Brühen. Dadurch ist die tatsächliche Brühtemperatur nicht immer präzise vorhersehbar.
  2. Abhängigkeit von Umgebungsbedingungen. Faktoren wie Raumtemperatur, Luftfeuchtigkeit und der Zustand der Maschine (z. B. Aufheizzeit) beeinflussen die Brühtemperatur erheblich. Ein fester Offset kann diese Variablen nicht dynamisch ausgleichen, was zu ungenauen Ergebnissen führen kann.
  3. Wärmeverlust bei Standzeiten. Nach längeren Pausen kühlt die Brühgruppe ab, und die Maschine benötigt Zeit, um wieder auf die gewünschte Temperatur zu kommen. Ein korrekt eingestellter Offset kann dies nicht kompensieren, weshalb zusätzliche Maßnahmen wie ein “Cooling Flush” nötig sind.
  4. Fehlkalibrierungen ab Werk. Bei einigen Lelit-Modellen wurde festgestellt, dass der Offset ab Werk oft ungenau eingestellt ist (z. B. 4–8 Grad zu niedrig bei der Lelit Bianca). Dies erfordert eine manuelle Nachkalibrierung durch Fachpersonal, was für Endnutzer kompliziert sein kann.
  5. Missverständnisse in der Anwendung. Viele Nutzer sind durch widersprüchliche Informationen zur Offset-Einstellung verunsichert, was zu Fehlanpassungen führen kann. Beispielsweise wird oft erwartet, dass der Offset allein alle Temperaturprobleme löst, obwohl er nur ein Teil eines komplexeren Systems ist.

Fazit
Die Offset-Kalibrierung ist ein nützliches Werkzeug, aber sie sollte nicht isoliert betrachtet werden. Eine Kombination aus präziser PID-Steuerung, regelmäßiger Wartung und angepassten Techniken (z. B. Spülshots) ist notwendig, um optimale Brühergebnisse zu erzielen.
