Mahlkönig manufactures some of the very best coffee grinders available. Its espresso grinders are known for being precise and consistent while also being reliable in the face of high volumes and busy rushes. While Mahlkönig is primarily known for its commercial offerings, recently it has developed a range of grinders for the home barista. For the serious enthusiast looking for uniform particle size and precise dosing, Mahlkönig has several premium offerings including the new E64 WS Grind-by-Sync.

Making delicious coffee requires consistent dosing. One of the technologies that Mahlkönig has pioneered to assist with this is Grind-by-Weight (GbW) dosing. First available in the commercial context, GbW dosing has become an expected standard at high-end coffee businesses, both to improve consistency and reduce waste. Mahlkönig has now further improved on this technology through Grind-by-Sync (GbS), which you can learn more about below. Mahlkönig is now making these technologies available to the home user with the E64 WS GbS Espresso Grinder.

About the Mahlkönig E64 WS GbS Home Espresso Grinder

With grind size adjustments down to the micrometre, the Mahlkönig E64 WS is designed to bring the intelligent features of the Grind-by-Sync range to the home espresso enthusiast. This grinder features an integrated load cell built into the portafilter fork and automatic detection for hands-free weight-based dosing. Thanks to this highly precise scale, the E64 WS displays exactly how much coffee ends up in your portafilter in grams. You can also programme different profiles for different portafilters so you can quickly switch between basket sizes or recipes.

Using the E64 WS espresso grinder's high-resolution dashboard, you can set and monitor the exact distance between your burrs. Thanks to Mahlkönig's patented Disc Distance Detection® you can set your grind size and always return to the same exact setting. DDD® means that calibrating your zero point requires just one press without disassembly or tools. Inside, ultra-sharp 64 mm special steel burrs deliver the precisely uniform particle distribution associated with the King of Grinders.

For your kitchen environment, this grinder features sound insulation for quiet operation and a customisable ambient lighting system along with a magnetic grind tray. If you are unsure about dialling in a certain coffee, the E64 WS features a handy but optional dial-in guide. The German team of engineers has also thoughtfully included an intelligent algorithm that anticipates retention for each dose.

About Mahlkönig's Grind-by-Sync system

Stepping beyond Grind-by-Weight and Grind-by-Time, Grind-by-Sync leverages Mahlkönig's precise grinding and DDD® technology with WiFi connectivity for greater particle size consistency and smart dosing. By syncing your GbS grinder with the Mahlkönig Sync Scale, you can use the Mahlkönig Sync App to set a target extraction time, and if the shot pulls too fast or too slow, the grinder automatically adjusts its own burr distance to match the target. This removes guesswork, variability, and the need for recurring dial-ins.

For those without a compatible espresso machine or who prefer manual adjustment, the Mahlkönig E64 WS GbS grinder operates without needing to sync with an app or a machine.
