Who It's For

The X54 is for a home barista who wants a genuine flat-burr grinder — the same burr shape Mahlkönig uses on its commercial line, not a smaller conical substitute — without buying commercial-sized equipment. If dialing in espresso through French press on one machine, with real stepless adjustment, matters more than saving counter space, this is built for that.

It also fits a household that wants app-based control: the Wi-Fi connection to the Mahlkönig Home app for saved recipes, brew-method dial-in guidance, and firmware updates is the X54's clearest differentiator from a purely mechanical home grinder, and the sub-70 dB(A) noise level and compact frame keep it livable in a shared kitchen.

It's not the choice for a shop needing commercial duty cycles, hopper capacity, or throughput — for that, look at the Mahlkönig EK43 or the rest of our equipment lineup. The X54 is sized and priced for a serious home setup, not a bar.

What's in the Box

The X54 includes a stainless steel portafilter dosing cup and two swappable front attachments, plus Wi-Fi connectivity to the Mahlkönig Home app out of the box.

Did You Know

• The X54's burrs are made in the same Hamburg, Germany facility as Mahlkönig's commercial grinders, using the same hardened tool-steel alloy and blasted finishing process — a detail that separates it from home grinders built around lower-grade burr sets.

• Mahlkönig rates the X54's motor for more than 25,000 shots — the company frames that as roughly 30 years of pulling two shots a day, well beyond the practical lifespan most home espresso setups need from a grinder.

• The X54 stays under 70 dB(A) during operation, a noise-level target Mahlkönig designed specifically for shared living spaces rather than a standalone workshop setup.

Are the Mahlkönig X54's burrs flat or conical?

Flat. The X54 uses 54 mm flat, special-steel burrs — the same burr geometry Mahlkönig uses on its commercial grinders, not a conical burr set.

Does the Mahlkönig X54 have Wi-Fi?

Yes — it connects to the Mahlkönig Home app for saved grind recipes, brew-method dial-in guidance, firmware updates, and usage stats.

Does the X54 have grind-by-weight?

Not gram-based grind-by-weight. It offers grind-by-time through the Mahlkönig Home app instead of a built-in scale.
