Mahlkönig E65W Grind-by-Sync

Precision That Adjusts With Your Coffee

Dialling in a commercial grinder is normally an ongoing process.

As coffee ages, environmental conditions change and extraction times move, the barista has to make adjustments to keep the espresso where it should be.

The E65W Grind-by-Sync is designed to take that process further.

It combines Grind-by-Weight dosing with Mahlkönig’s Grind-by-Sync system, allowing the grinder to communicate with compatible espresso machines and Sync-enabled equipment. Instead of simply grinding a programmed dose, the system can use extraction data to adjust the burr position and help keep the grinder aligned with the desired extraction time.

For a busy café, this means less manual intervention and greater consistency throughout the day.

Why We Stock It

The E65W GbS isn’t simply a faster version of a home grinder.

It’s designed around the realities of commercial espresso service, where consistency matters from the first shot of the morning to the last shot of the day.

The combination of 65mm flat burrs, electronic grind adjustment, Grind-by-Weight dosing and Grind-by-Sync gives baristas an unusually high level of control while reducing some of the repetitive adjustment normally required during service.

It’s particularly interesting for cafés that want to start moving towards a more connected and automated espresso workflow without sacrificing the ability of the barista to remain in control.

Grind-by-Sync Technology

The standout feature of the E65W GbS is the Sync System.

The grinder can connect with compatible commercial espresso machines or other Sync-enabled devices. Extraction information can then be used by the grinder’s intelligent control system to automatically adjust the burr distance and help maintain the target extraction time.

The grinder can also be operated manually, allowing the barista to make their own adjustments when required.

This gives you two approaches:

Manual control when you want it.

Automated adjustment when you need it.

Grind-by-Weight

The integrated weighing system measures the coffee being dispensed and stops the grinder at the programmed target dose.

This provides more consistent dosing than relying purely on grinding time, particularly as bean density and grinding conditions change.

For a busy café, accurate dosing also means less coffee being unnecessarily wasted during service.

Features

65mm Special Steel Flat Burrs

The E65W uses 65mm special steel flat burrs designed for commercial espresso production. Mahlkönig rates the burrs for approximately 800kg of coffee at the median setting.

Electronic Grind Adjustment

Instead of manually turning a conventional grind collar, the E65W uses electronic adjustment of the burr distance. This provides extremely precise control and forms the basis of the Grind-by-Sync system.

Grind-by-Sync

When connected to compatible equipment, the grinder can use extraction information to automatically adjust the grind to help maintain the target extraction time.

Grind-by-Weight

The integrated weighing system provides precise dosing directly into the portafilter, helping maintain consistent recipes throughout service.

High-Resolution Display

The large 88.3mm high-resolution display provides clear, real-time information during operation.

Adjustable Illuminated Spout

The illuminated dispensing spout can be positioned to provide a clean, centred delivery of coffee into the portafilter.

Quiet Commercial Grinding

The E65W has been designed with noise reduction in mind, with Mahlkönig specifying approximately 70 dBA during grinding.

1.2kg Bean Hopper

The standard hopper holds approximately 1.2kg of coffee, making it suitable for continuous commercial service. A smaller 250g hopper and larger 1.8kg hopper are also available as optional accessories.

Mahlkönig Sync Ecosystem

The grinder works with the Mahlkönig Sync digital ecosystem, including the Sync mobile and desktop applications.

Aura Bean Grinding Tip

The Grind-by-Sync system is most useful when the rest of your espresso workflow is equally consistent.

Make sure your dose, yield, puck preparation and water temperature are controlled before relying heavily on automated grind adjustment. The technology can help keep extraction on target, but it can’t compensate for inconsistent preparation or a recipe that hasn’t been properly dialled in.

For cafés, the real benefit is what happens after the coffee has been dialled in: the grinder can help maintain that target as the coffee changes throughout the day.

---

The Aura Bean Difference

Commercial equipment should make service easier, not simply add more technology to the counter.

The E65W is interesting because its technology addresses a genuine café problem: keeping espresso consistent as conditions change.

With Grind-by-Weight controlling the dose and Grind-by-Sync helping manage grind adjustment, it gives the barista a much more controlled workflow while still allowing manual intervention when needed.

For a specialty coffee business where consistency, speed and waste reduction matter, this is the kind of grinder that can make a measurable difference to the daily operation.
