Mahlkönig E64 WS Home – App control & cloud connectivity

The Mahlkönig E64 WS Home combines precise espresso grinding with smart connectivity. Use the Mahlkönig Sync app (iOS/Android) to control your grinder, analyze extractions, and automatically keep your firmware and features up to date.

Optimized ejection – new flapper version

The current version of the E64 WS Home is equipped with the redesigned flapper system. This consists of a silicone de-clumper with an additional stainless steel element, which bundles the ejection and ensures a controlled, clean grind.

Espresso can be particularly fluffy and light, especially with very light roasts. The optimized flapper reduces scattering in the portafilter and ensures a more even, precise extraction.

As with all high-quality espresso grinders, regular cleaning of the discharge area is recommended to ensure consistently good results.

Good to know: New devices are already delivered with the latest flapper version.

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

Why the smartphone app makes all the difference

  • Convenience: Manage grind sizes, doses, and profiles conveniently via smartphone.
  • Consistency: Repeatable results thanks to saved recipes and digital scaling.
  • Transparency: usage statistics, history data, and status messages at a glance.
  • Future-proof: Over-the-air updates for new features and improvements.

Features 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 size to target extraction times – for consistent shots without readjustment.

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

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

  • Calibration & diagnostics
    Guided zero calibration, status checks, and maintenance tips for consistently accurate results.

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

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

Synchronized with the espresso machine

When connected to 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. The result: shot-for-shot consistency without guesswork.

Intuitive operating concept

  • OLED display on the grinder for direct control without a smartphone.
  • Electronic grind adjustment for reproducible settings.
  • Ball joint spout – centered dispensing directly into the portafilter.
  • Ambient light – adjust colors via app to suit your setup and style.
  • Automatic detection: Automatically detects portafilter and can produce recipes after portafilter detection.

Conclusion: The E64 WS Home is more than 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 to 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.

Můžete provést offset kalibraci na mém pákovém kávovaru?

Existuje několik argumentů, které hovoří proti kalibraci offsetu u kávovarů Lelit, zejména u modelů jako Lelit Bianca. Tyto argumenty se týkají především složitosti a omezení offsetu jako jediné řešení problémů s teplotou:

  1. Kolísání teploty a nestabilita. Offset zohledňuje konstantní rozdíl mezi teplotou kotle a teplotou vaření. V praxi však mohou nastat kolísání teploty, např. kvůli delším dobám stání nebo kontinuálnímu vaření. Tím pádem není skutečná teplota vaření vždy přesně předvídatelná.
  2. Závislost na podmínkách prostředí. Faktory jako teplota místnosti, vlhkost vzduchu a stav stroje (např. doba zahřívání) výrazně ovlivňují teplotu vaření. Pevný offset nemůže tyto proměnné dynamicky vyrovnat, což může vést k nepřesným výsledkům.
  3. Ztráta tepla při stání. Po delších přestávkách se vařící skupina ochladí a stroj potřebuje čas, aby se znovu dostal na požadovanou teplotu. Správně nastavený offset to nemůže kompenzovat, proto jsou nutná další opatření, jako je "Cooling Flush".
  4. Chybné kalibrace z výroby. U některých modelů Lelit bylo zjištěno, že offset je často z výroby nastaven nepřesně (např. o 4–8 stupňů nižší u Lelit Bianca). To vyžaduje manuální překalibraci odborným personálem, což může být pro koncové uživatele komplikované.
  5. Nedorozumění v aplikaci. Mnoho uživatelů je zmateno protichůdnými informacemi o nastavení offsetu, což může vést k nesprávným úpravám. Například se často očekává, že offset sám vyřeší všechny problémy s teplotou, i když je pouze součástí složitějšího systému.

Závěr
Kalibrace offsetu je užitečný nástroj, ale neměla by být považována za izolovanou. Kombinace přesného PID řízení, pravidelné údržby a přizpůsobených technik (např. vyplachovací záběry) je nezbytná pro dosažení optimálních výsledků vaření.
