Overview
The Mahlkönig EK43S is the short-hopper variant of the iconic EK43, designed for environments where vertical clearance is limited. It retains the same legendary 98mm flat burr set and motor as its taller sibling, delivering identical grind quality in a more compact form factor. The shorter hopper encourages single-dosing workflows, which has made the EK43S particularly popular with specialty coffee shops and ambitious home users. Every bit as capable as the full-size EK43, the S variant has become the preferred choice for many who want EK43 performance in a slightly more manageable package. The same revolutionary grind quality that changed the coffee industry, in a more counter-friendly size.
The Mahlkönig EK43S features a 98mm flat burr set, crafted from steel. The burrs spin at 1380 RPM, offering fast grinding for high-volume use. Grind retention is approximately 1.5g, typical for a hopper-fed workflow.
At $2,700, the Mahlkönig EK43S is aimed at uncompromising enthusiasts and professionals who want the absolute best. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.
The Mahlkönig EK43S is weighing 21.0 kg, manufactured in Germany, powered by a 550W motor. Its footprint measures 205 x 390 x 620 mm (W×D×H).

Our Verdict
The Mahlkönig EK43S uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. This is an end-game grinder for dedicated enthusiasts. The price is substantial but reflects the engineering required for top-tier particle uniformity. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions

Yes, the Mahlkönig EK43S is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Is the Mahlkönig EK43S good for single dosing?
Yes, the Mahlkönig EK43S is designed for single dosing. With only 1.5g of retention, virtually all the coffee you put in comes out ground. Weigh your beans before grinding for the most consistent results.
Why choose flat burrs in the Mahlkönig EK43S?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Mahlkönig EK43S?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
Is the Mahlkönig EK43S worth $2,700?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Mahlkönig EK43S will have a bigger impact on your espresso than upgrading any other piece of equipment. If you're serious about espresso, this level of grinder investment is justified.
