About the Mahlkönig E64 WS
Mahlkönig Brings Its Commercial DNA Home — Without Compromise.
Mahlkönig has been manufacturing professional coffee grinders for café bars, competitions, and high-end restaurants since 1924. The E64 WS is the brand's first grinder designed specifically for home use — and it carries the same engineering rigour that makes Mahlkönig equipment the choice of World Barista Champions and Michelin-starred kitchens worldwide. This is not an entry-level machine with a Mahlkönig badge. It is a genuine professional instrument engineered for domestic scale.
At the heart of the E64 WS is Grind by Weight — the same technology used in Mahlkönig's E65S GBW commercial grinder. An integrated precision scale measures the dose directly and stops the grinder at your target weight, accurate to 0.1g. This eliminates the most common source of espresso inconsistency for home baristas: dose variation between shots. Set your recipe once and the E64 WS repeats it with a precision that manual timing cannot match.
Electronic Disc Distance Detection monitors the distance between the burrs in real time, measured in microns, and automatically compensates for temperature-induced grind drift during extended use. In practice, your first shot and your tenth shot grind at the same particle size — without manual recalibration. The result is extraction consistency that home baristas with conventional grinders can only achieve through constant monitoring and adjustment.
The Grind by Sync system connects the E64 WS to compatible smart espresso machines — when paired, the machine and grinder communicate to align grind distance with your programmed recipe automatically. As the burrs heat up during a session, the grinder self-corrects so your workflow remains consistent without interruption. Available in Matte Black, the E64 WS ships May 2026. Di Pacci is taking preorders now at the launch price of $1,949.

Three Technologies That Set the E64 WS Apart
Grind by Weight
An integrated precision scale measures the dose as it grinds and stops automatically at your target weight — accurate to 0.1g. No timed dosing, no over/under-grinding, no manual adjustment between shots. Set your recipe once and the E64 WS delivers it exactly, every time.
Electronic Disc Distance Detection
Sensors monitor the distance between the burrs in real time, measured in microns, and automatically compensate for thermal expansion as the grinder heats up during a session. Your grind size stays where you set it — not where temperature drift takes it. A feature previously exclusive to Mahlkönig's commercial machines.
Grind by Sync
When paired with a compatible smart espresso machine, the E64 WS and machine communicate directly — aligning grind distance with your saved recipe and adjusting automatically as conditions change. As your session progresses and burrs heat up, the system self-corrects without you touching a setting.
Full Feature Overview
What Makes the E64 WS Worth the Investment
Every feature traces back to one goal — removing the variables between your recipe and your cup so you can focus on the coffee itself.
64mm Hardened Steel Flat Burrs
The E64 WS runs 64mm hardened steel flat burrs — the same burr diameter and material standard found in Mahlkönig's commercial espresso grinders. Larger flat burrs grind faster at lower RPM, generate less heat, and produce a more uniform particle size distribution — all of which directly improve extraction clarity and flavour consistency, especially on quality single-origin coffees and lighter roasts.
Grind by Weight — 0.1g Accuracy
The integrated precision scale eliminates timed dosing entirely. You set a target dose weight, press the portafilter against the grinder, and it stops automatically when it reaches exactly that weight. Shot-to-shot dose variation — one of the most common sources of espresso inconsistency at home — is removed from the equation. The same technology powers Mahlkönig's E65S GBW, one of the most respected commercial grinders in the world.
Electronic Disc Distance Detection
As burrs heat up during a grinding session, they physically expand — changing the actual gap between them and shifting the effective grind size even if you haven't touched the adjustment dial. The E64 WS measures this gap continuously in microns and automatically compensates. Your first shot and your eighth shot grind at the same particle size, regardless of burr temperature — without any user input.
Grind by Sync Smart Connectivity
For home baristas with compatible smart espresso machines, Grind by Sync creates a closed loop between the grinder and machine. As conditions change — burr temperature, ambient temperature, bean density — the system adjusts the grind distance to maintain your programmed extraction profile automatically. Effectively, the grinder and machine manage recipe consistency together so you don't have to.
Compact Home-Scale Footprint
Despite carrying commercial-grade technology, the E64 WS is engineered for home kitchen dimensions. At 20.5cm wide and 5.8kg, it occupies a fraction of the space of a commercial grinder while delivering the same dosing precision. The 250g hopper is sized for household use — enough for a daily session without the stale-bean risk of a larger commercial hopper.
Portafilter Detection — Hands-Free Grinding
Press the portafilter against the fork and the E64 WS starts automatically, grinding to your set weight and stopping without any additional button presses. Remove the portafilter and the grinder pauses. A fluid, intuitive workflow that matches the pace of a properly run café bar — adapted for home use without any operational complexity.
100 Years of Mahlkönig Engineering Heritage
Mahlkönig has been engineering professional coffee grinders since 1924 — a century of continuous development that makes every component decision in the E64 WS an informed one. The brand's grinders are used at the World Barista Championship, World Brewers Cup, and in Michelin-starred restaurants globally. The E64 WS is the first time this lineage has been fully expressed in a machine designed for home use.
Global Certification — Australian Compliant
The E64 WS carries a comprehensive suite of safety and compliance certifications including SAA (Standards Australia) and RCM — confirming full compliance with Australian electrical safety and electromagnetic compatibility requirements. Also certified CB, CE, KC, PSE, UKCA, ETL, ROHS, CCC, and NSF. Backed by the standard Di Pacci new product warranty with full Australian after-sales support.

Common Questions
Mahlkönig E64 WS — Frequently Asked Questions
What is Grind by Weight and why does it matter for home espresso?
Grind by Weight uses an integrated scale to measure your dose in real time and stop the grinder automatically when it reaches your target weight — accurate to 0.1g. Most home grinders use timed dosing, which delivers a different dose weight every time the bean density, hopper level, or burr temperature changes. Grind by Weight eliminates that variation entirely. A consistent dose is the foundation of consistent espresso extraction — dose variation of even 0.5g can meaningfully change shot timing, yield, and flavour. Once set, the E64 WS delivers the same dose shot after shot without any user intervention.
What is Electronic Disc Distance Detection?
As the burrs grind coffee, friction generates heat that causes the burrs and grinder components to expand physically — a process called thermal expansion. This expansion changes the actual gap between the burrs, shifting the effective grind size even if you haven't touched the adjustment dial. Electronic Disc Distance Detection monitors the burr gap continuously in microns and adjusts automatically to compensate, keeping the grind particle size consistent throughout your session. The result is that your first shot and your eighth shot extract identically — no manual recalibration needed as the grinder heats up.
Which espresso machines are compatible with Grind by Sync?
Grind by Sync requires a compatible smart espresso machine that supports the Mahlkönig communication protocol. The feature is designed to integrate with current-generation smart machines that offer digital recipe management — including machines from brands such as La Marzocco that support the Home Connect ecosystem. Contact Di Pacci on (02) 9758 0760 to discuss compatibility with your specific espresso machine before purchasing.
How does the E64 WS compare to the Lelit William PL72 or Macap MXD?
The Mahlkönig E64 WS operates at a different technical level to the Lelit William PL72 ($849) and Macap MXD ($1,883+). Both the William and MXD use timed dosing — the E64 WS uses precision weight-based dosing accurate to 0.1g, which is categorically more consistent. The Electronic Disc Distance Detection is also unique to the E64 WS in this price tier — neither the William nor any Macap model compensates automatically for thermal grind drift. At $1,949, the E64 WS carries a premium over those grinders that is fully justified by the technology it delivers.
When will the Mahlkönig E64 WS be available in Australia?
The Mahlkönig E64 WS is available for preorder now at Di Pacci at $1,949 (launch price). Dispatch is scheduled for May 2026. Di Pacci is Australia's authorised Mahlkönig stockist and is one of the first retailers to offer the E64 WS in the country. To secure your unit, preorder online at dipacci.com.au or call our team on (02) 9758 0760. Stock is limited at the launch price.
Is the Mahlkönig E64 WS suitable for filter coffee or only espresso?
The Mahlkönig E64 WS is designed and optimised specifically for espresso grinding. Its 64mm flat burrs, precision electronic grind adjustment, and Grind by Weight system are all calibrated for the fine, consistent grind required for espresso extraction. While the grinder can physically grind coarser, its electronic systems and workflow are not optimised for filter, pour-over, or plunger use. If you need a single grinder that covers both espresso and filter, Di Pacci recommends discussing your full setup with our team before purchasing.
Who the E64 WS Is Built For
Is the Mahlkönig E64 WS Right for Your Setup?
🎯
Precision-Focused Home Baristas
If you weigh your dose on a scale before grinding, track your extraction yield, and adjust your recipe systematically — the E64 WS automates the precision you're already trying to achieve manually. Grind by Weight replaces your scale, Electronic Disc Distance Detection replaces your recalibration routine, and the result is more time spent tasting your coffee and less spent managing variables.
🏠
Serious Home Espresso Enthusiasts
If you own or are considering a quality traditional espresso machine — La Marzocco, ECM, Profitec, Lelit, Rocket — and you want a grinder at the same level of engineering seriousness, the E64 WS is the natural match. A machine that costs $3,000–$5,000 deserves a grinder that performs to the same standard. The E64 WS is that grinder.
📱
Smart Machine Owners
If you have a compatible smart espresso machine that supports the Grind by Sync protocol, the E64 WS closes the loop between your machine and your grinder — creating a connected espresso system that manages recipe consistency automatically. This is the most advanced home espresso workflow available at any price point from a single grinder purchase.
