Who It's For

The E65W GbS is for an operation that wants both problems solved at once — dose weight and grind drift — on a single grinder tied into a compatible La Marzocco machine. That's a multi-barista specialty bar or a multi-location brand running (or planning) an AV/ABR-configured La Marzocco platform, where the value of Sync's automatic correction compounds with GbW's per-shot weight accuracy: the grinder is both weighing every dose and adjusting its own fineness based on how the last few shots actually pulled.

A single-location café that wants gravimetric dosing but doesn't run a Sync-compatible machine doesn't need this model — the E65S GbW delivers the same real-time weight accuracy without the connected layer, at a lower price. And a bar that wants Sync's automatic correction but is fine with timed rather than weighed dosing should look at the E65T GbS instead. The E65W GbS earns its place specifically where both technologies are actually going to be used, not just one.

Did You Know

• The E65W GbS's load cell samples weight up to 6,000 times per second while the dose is being ground — far more frequently than a barista could ever read a scale by eye, which is what lets the grinder stop dosing at a precise target weight rather than overshooting it.

• Sync pairs specifically with named La Marzocco machines, not any commercial espresso machine generally: the Strada S, KB90, Linea PB, Linea PB X, Linea Classic S, GB5 S, and GB5 X, each in AV or ABR configuration — a defined list rather than a generic "compatible with most machines" claim.

• The E65W is the only Mahlkönig E-series model running two feedback loops on the same shot at once — a load cell tracking dose weight in real time, and a Sync connection separately tracking that shot's extraction time against the connected machine's own recipe target.

What does Grind-by-Weight mean on the Mahlkönig E65W?

A load cell built into the grinder weighs the dose in real time as it's ground — up to 6,000 times per second — stopping at a target weight instead of relying on a fixed grind duration.

What does Grind-by-Sync add on top of Grind-by-Weight?

It connects the grinder to a compatible La Marzocco machine, which reports each shot's actual extraction time back to the grinder so it can automatically correct its own burr distance if recent shots ran outside the target recipe time.

Which La Marzocco machines pair with the E65W GbS?

Strada S, KB90, Linea PB, Linea PB X, Linea Classic S, GB5 S, and GB5 X, each in AV or ABR configuration.

What burr size does the E65W GbS use?

65 mm flat special-steel burrs, the same platform as the E65S, E65S GbW, and E65T GbS.

What's the difference between the E65W and the E65T?

Both run Grind-by-Sync on the same 65 mm burrs; the E65W adds a load cell for real-time weight-based dosing, while the E65T stays timed.

Does the E65W GbS need WiFi to work as a grinder?

No — it grinds and doses by weight on its own without a connection. WiFi (or a wired cable) is only needed for the Sync correction feature to receive shot-timing data from a paired machine. See the rest of the connected lineup on the grinders category page.
