The Intelligent Standard: Professional Precision for the Home

The Mahlkonig E64 WS is a groundbreaking espresso grinder that brings commercial-grade Grind-by-Weight (GbW) technology into a compact, home-friendly footprint. Its defining innovation is the Grind-by-Sync system, which allows the grinder to communicate wirelessly with compatible espresso machines (like the Mahlkonig Xenia). Through this connection, the grinder can automatically adjust its grind size in real-time based on the extraction data of the previous shot—essentially "dialling itself in" to maintain your perfect recipe without manual intervention.

At its mechanical core, the E64 WS features professional 64 mm flat steel burrs and a high-torque motor capable of grinding at a rapid speed of 3 grams per second. It utilizes an electronic, micron-accurate grind adjustment system powered by Mahlkonig’s patented Disc Distance Detection (DDD), which ensures your settings are perfectly repeatable every time. With a whisper-quiet operation (under 65 dB), an integrated OLED display, and a customizable ball-joint spout for mess-free dosing, it is designed for the high-end enthusiast who demands the absolute peak of consistency and smart integration.

Specification for Mahlkonig E64 WS

• Burr Type: 64 mm special steel flat burrs
• Burr Speed: Up to 1,950 rpm
• Dosing Accuracy: 0.1 g with Grind-by-Weight technology
• Adjustment System: Electronic micrometric adjustment with disc distance detection
• Hopper Capacity: 250 g low-profile hopper with slider
• Noise Level: Approx. 65 dBA (whisper-quiet operation)
• Power Consumption: 200 W
• Dimensions (W × H × D): 20.5 × 33.5 × 48.5 cm
• Net Weight: 5.8 kg

To keep the grinder running at its best, Mahlkonig specifies the following operational limits:

• Max. Daily Output: Approx. 2.5 kg (around 125–140 double espressos)
• Max. Operating Cycle: 6 seconds ON / 54 seconds OFF
• Hopper Capacity: 250 g
• Grinding Speed: Approx. 2–3.5 g/s, depending on grind size

Motor Protection: The "6s on / 54s off" cycle is a guideline to prevent the motor from overheating.1 If you exceed this frequently, the grinder may trigger a thermal shutdown to protect its internal electronics.

Consistency: Keeping the output within the 2.5 kg limit ensures that the burrs don't get too hot, which can affect the flavour profile and extraction of your espresso.

Home vs. Commercial: While it can handle a small office or a very busy home gathering, it is not intended for continuous back-to-back service in a high-volume café."

Mahlkonig's E64ws Sync System

The Future of Coffee Precision: Inside the Mahlkonig Sync Ecosystem
For decades, the "perfect shot" was a moving target, dependent on a barista’s constant manual adjustments to account for bean age, humidity, and temperature. Mahlkonig has effectively solved this inconsistency with its new integrated ecosystem. By linking the grinder, espresso machine, and scale through a digital "brain," the system creates a closed-loop feedback cycle that maintains your recipe automatically.

The Hardware: Xenia and E64 WS

The foundation of this system lies in two groundbreaking pieces of hardware designed to bring commercial-grade automation into boutique and home environments.

• Mahlkonig Xenia Espresso Machine: This is Mahlkonig's first official foray into espresso machines. It is engineered from the ground up to prioritise thermal stability and pressure control. When paired with a Sync-enabled grinder, the Xenia acts as the data hub, recording the exact flow rate and extraction time of every shot.

• E64 WS Grinder: Built specifically to house the Grind-by-Sync technology, the E64 WS features an electronic motor that moves the burrs to the exact micron. Unlike traditional grinders where you manually turn a dial, the E64 WS adjusts itself based on data received from the machine or scale.

In-Depth: How the Sync System Works

The Sync System is a real-time communication protocol that eliminates "shot drift." Here is how the automated loop functions in a live environment:

1. The Target: You set a recipe in the Sync App (e.g., 18g dose, 36g yield, 28-second extraction).

2. The Extraction: As the Xenia (or a machine using the Sync Scale) pulls the shot, it measures the time it takes to reach the target yield.

3. The Analysis: If the shot pulls in 24 seconds (too fast), the system identifies that the grind is too coarse.

4. The Auto-Correction: The machine sends a signal to the E64 WS. The grinder’s internal motor instantly adjusts the burrs to a finer setting. Your very next dose is already corrected, ensuring the subsequent shot hits the 28-second target perfectly.

The Sync Scale: Retrofitting Precision

For those using traditional espresso machines without built-in connectivity, the Mahlkonig Sync Scale serves as the essential bridge. It features high-speed WiFi to transmit weight and timing data directly to the Mahlkonig Cloud.

• Real-Time Feedback: The scale times the shot and sends the data to the grinder to trigger the same automatic burr adjustments found in integrated setups.

• Professional Build: It is constructed with a powder-coated aluminium body and a heat-resistant glass display to withstand heavy use.

The Sync App: The Master Controller

The Sync App (available on iOS and Android) is the digital dashboard for the entire setup. It is designed to be intuitive enough for home enthusiasts but powerful enough for multi-site café managers.

• Recipe Management: Create a library of recipes for different beans. When you switch beans, you simply push the new recipe from the app, and the grinder adjusts itself to the pre-saved micron setting.

• Device Pairing: A simplified interface to link your E64 WS, Xenia, and Sync Scale via Bluetooth or WiFi.

• Insights and Maintenance: The app tracks burr wear and provides "Predictive Maintenance" alerts, telling you exactly when it's time to service your equipment based on actual kilograms ground.
