Who It's For

The EK43 is for shops and roasteries that want one grinder handling everything from espresso to pour-over to cold brew to Turkish coffee at a professional level, rather than running separate grinders per method. If the bar's standard is a single all-purpose machine a barista can dial from Turkish-fine to coarse filter without swapping equipment, this is that machine.

It also suits operations that specifically want the grinder with the competition and industry track record behind it — the one whose reputation for espresso started on a World Barista Championship stage and has since become the default choice serious specialty operations reach for. For a brand where having "the standard" behind the bar matters as much as the grind itself, that history is a real factor.

What it's not built for: a tight under-counter footprint, since its 82.8 cm / 32.6 in height won't clear every shelf — the shorter EK43 S covers that case. Shops wanting digital recipe recall and a touchscreen are better served by the newer EK43 OMNIA, built on the same grinding platform.

What's in the Box

The EK43 ships with a bag holder for grinding directly into retail bags. Mahlkönig sells alignment and pulling tools, additional hopper sizes, and stainless steel dosing cups as separate accessories — none of them included with the base unit.

Did You Know

• A World Barista Championship performance put the EK43 on the map for espresso, not just filter. At the 2013 World Barista Championship, Australian barista Matt Perger built his entire routine — espresso shots and filter-style pours alike — around a single EK43, finishing runner-up and popularizing the idea that a large filter/batch grinder could out-perform dedicated espresso grinders on clarity and sweetness.

• "Mahlkönig" literally means "grinding king" in German. The name (often written "Mahlkonig" without the umlaut in English-speaking markets) is a straightforward boast that stuck — and the EK43's cast-steel burrs are still produced at the company's Hamburg facility, now part of the Hemro Group.

• The EK43's burrs are hardened to 64–66 HRC and glass bead-blasted on purpose, not just for finish. That hardness and surface treatment are engineered to resist burr "settling" over time, which is part of how Mahlkönig gets a rated grind life of roughly 6,000 kg per burr set at a median setting.

What burr size does the Mahlkönig EK43 use?

The EK43 uses 98 mm flat cast-steel burrs, hardened to 64–66 HRC with a glass bead-blasted finish, rated for roughly 6,000 kg of grind life at a median setting.

Is the EK43 good for espresso?

Yes — despite being built as an all-purpose grinder, the EK43 became known for espresso specifically after Matt Perger used one for his entire 2013 World Barista Championship routine. Its stepless, calibratable grind adjustment goes fine enough for espresso and coarse enough for filter and French press.

What's the difference between the EK43 and the EK43 S?

The EK43 S uses the identical 98 mm burr set, 1,300 W motor, and grind range as the standard EK43 — the only real difference is a roughly 15 cm / 6 in shorter body designed to fit under lower shelves and tighter counter configurations.

Does the EK43 have grind-by-weight?

No. The EK43 is a stepless, manually-dialed grinder without a built-in scale or grind-by-weight feature. For digital recipe recall on the same grinding platform, see the EK43 OMNIA.

How much does the Mahlkönig EK43 weigh?

Mahlkönig lists the EK43 at 57 lb (26 kg) net, or about 66 lb (30 kg) in its shipping crate.

What colors does the EK43 come in?

Black, White, and Copper.

Does the EK43 come with a bag holder?

Yes — a bag holder for grinding directly into retail bags ships standard. Additional hoppers, dosing cups, and alignment/pulling tools are sold separately.
