Who It's For

The E65T GbS is for an operation that wants a compatible espresso machine's own shot data doing the dial-in work — a specialty bar with multiple baristas rotating through a shift, or a multi-site brand that wants grind settings to correct themselves toward the same recipe target rather than depending on whoever's on bar. Because Sync connects to La Marzocco's AV and ABR-configured commercial machines specifically, it's the right fit for a shop that already runs (or is choosing) a compatible La Marzocco platform — the value here is in the connection between the two machines, not the grinder alone.

It's the timed half of Mahlkönig's Sync pair: dose weight is still set on a timer, not measured by a load cell, which keeps the price and complexity lower than the gravimetric E65W GbS while still delivering Sync's automatic correction. A shop that wants both real-time weight verification and Sync's shot-timing correction in one grinder should compare the E65W GbS. A bar that doesn't run a Sync-compatible machine, or doesn't need connected correction at all, is better served by the plain E65S GbW for gravimetric dosing without connectivity.

Did You Know

• The Sync System is a joint development between Mahlkönig and La Marzocco, publicly launched in 2023 as a purpose-built pairing between one manufacturer's grinders and the other's commercial espresso machines — not a third-party integration bolted on afterward.

• Sync's correction is based entirely on extraction time, not weight. The connected espresso machine records how long the last shot(s) ran, compares that against a set recipe time, and the grinder adjusts its burr gap finer if shots ran fast or coarser if they ran slow.

• The E65T GbS can take a smaller 250 g hopper or a larger 1,800 g hopper as optional accessories, on top of the roughly 1,200 g hopper it ships with — useful for a bar with unusually low bean turnover or one that wants to minimize refills during peak service.

What does Grind-by-Sync mean on the Mahlkönig E65T?

It means the grinder connects to a compatible espresso machine and automatically corrects its own grind setting based on how long recent shots actually took to pull, compared against a set recipe time — no manual dial-in required after the initial setup.

Which espresso machines is the E65T GbS compatible with?

La Marzocco commercial machines in AV or ABR configuration, including the Strada S, KB90, Linea PB, Linea PB X, Linea Classic S, GB5 S, and GB5 X.

Is the E65T GbS a Grind-by-Weight grinder?

No — it doses on a timer. For the same Sync connectivity plus real-time weight-based dosing, see the E65W GbS.

What burr size does the E65T GbS use?

65 mm flat special-steel burrs, the same platform shared with the E65S, E65S GbW, and E65W GbS.

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

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

Does the E65T GbS need WiFi to work?

No — Sync can connect over WiFi or through a wired USB cable to the espresso machine, so a bar without reliable WiFi can still use the wired connection. Compare the rest of the connected lineup on the grinders category page.
