Mahlkönig EK43 (Stock 98mm)

The Mahlkönig EK43 story is an accidental revolution. Around 2010, this spice grinder — designed for grinding cocoa, pepper and stones — appeared in a specialty café in London and reshaped the market.

The burrs that changed everything

The EK43's 98mm flat burrs weren't originally designed for coffee. The geometry suited grinding coarse materials with high consistency — something nobody thought would be relevant to brewing. But baristas working with the grinder discovered it produced especially uniform and bright distribution of coffee particles. The cup came out clean, with flavor separation no other commercial grinder of the era was producing.

Matt Perger at the 2012 World Brewers Cup

Perger showcased the EK43 at his first major Brewers Cup and won. That win didn't take long to spark the grinder's viral moment. A year later, EK43-fever spread through the community: every specialty café bought one. Home users began ordering them for their kitchens.

What the cup shows

The EK43's stock burrs show a balanced and bright profile distinct from modern specialty. They give:

- Relatively high clarity compared to other contemporary burrs

- Body that isn't light but isn't full — middle ground

- Clean acidity without sharp edges

- Some sweetness with medium roasts

This isn't the "competition specialty" cup we recognize today, but it was the on-ramp into specialty. It proved you could pull high-quality coffee without a commercial grinder.

The decline and the aftermarket rise

After 5-7 years, the community began to see that the stock burrs, important as they were, weren't the limit. SSP developed 98mm sets with tighter geometry (HU, Brew, MP) — and they swarmed the EK43.

Today, most EK43s in the specialty world run on SSP, not the stock burrs. But the stock burrs are still excellent as a baseline, great for medium-dark espresso, and ship default with new EK43s.

Worth remembering

98mm flat burrs — the size everyone upgrades to, the axis specialty lines like SSP build around — were invented on the EK43. It's the foundation of the entire 98mm catalog you see in this section.
