Mahlkonig's E65W GbS is an intelligent grinder that addresses all of the key needs of the barista to ensure consistent and excellent espresso no matter who's behind the bar. Doses are programmed by weight and are accurate within 1/10th of a gram. The Grind-by-Sync functionality delivers on two fronts. First, burr position is now tracked digitally and adjusted via a motor with two built-in sensors. Second is that the grinder can be connected to one of several compatible machines from La Marzocco and Sanremo in order to automatically adjust grind size throughout the day via the Sync System.

The following machines are compatible with Grind-by-Sync:

La Marzocco

Strada S, KB90, Linea PB, Linea PB X, Linea Classic S, GB5 S, or GB5 X in AV or ABR configurations

Sanremo

Café Racer, F18 Multiboiler, F18 SB, D8 PRO, or D8 standard

Features and Benefits

The Grind-by-Sync functionality of the E65W GbS allows the grinder to be connected to a compatible espresso machine from La Marzocco or Sanremo. Grind-by-Sync works by connecting the grinder to the espresso machine via Wifi or a wired cable and programming your desired recipe. Recipes in the E65W GbS contain your desired coffee dose by weight, your desired burr position, and your extraction time. Shot time is communicated to the grinder from the machine and burr position is adjusted automatically as needed if the reported shot time is too fast or too slow. The grinder will course correct throughout the day, leaving baristas free to focus on other tasks while espresso remains consistent.

Mahlkonig's Disc Distance Detection or DDD system is an automated burr positioning system that digitally tracks burr position and makes adjustments via a sensor controlled motor. Grind adjustment is accurate within 0.001mm and is tracked onscreen as μm.

When utilizing Grind-by-Sync, the burrs will adjust themselves automatically based on extraction data received from the machine. Even without the Sync System, DDD is incredibly useful for calibrating multiple grinders for the same coffee and simple zero-point calibration with a dedicated menu option to zero burrs as needed, such as when installing new burrs or after a deep clean of the grinder.

Weight based grinding allows you to program multiple doses by weight within 1/10th of a gram with dispensing accurate within 1/10th of a gram. Unique to Mahlkonig is their portafilter detection feature which, when selected, will automatically select and grind a dose based on the portafilter inserted. In cases where multiple portafilters are used by baristas, this eliminates the need to select a specific dose when changing portafilters based on different drink recipes as necessitated by a workflow.

Coffee is ground by a set of 65mm flat steel burrs and a powerful 580 W motor with an idle rpm of 1,700. The E65W GbS is able to achieve impressive grinding speeds of up to 5-6g/sec at 250μm. Programming and menu navigation are made simple by the vivid touchscreen display, buttons and rotary encoder knob.

Why You Should Get It

The E65W GbS is all about precision. Grinding by weight with 0.1g accuracy is really just the tip of the iceberg when you factor in precision grind size thanks to the DDD system, and of course the ability to sync with compatible machines to maintain consistent extractions all day without disruption. The 65mm burrs and 5-6g/s speed make this an ideal grinder from most commercial environments with the exception of super-high volume shops.
