Mahlkönig EK43 S – compact 98mm all-round grinder for espresso and filter
An espresso in the morning, a pour-over in the afternoon, maybe a French press in between – and all from one grinder: The EK43 S grinds from Turkish-fine to coarse, cleanly separated and with a uniformity that translates in the cup as clarity and a long, round finish. It is precisely this versatility that has made the EK family legendary.
The EK43 S brings the large 98mm grinding mechanism of the iconic EK43 into a more compact housing – ideal for smaller coffee bars that prioritize particle consistency. As a Mahlkönig partner, we will align it to your brewing method and assist you with the settings.
What makes the EK43 S special
98 mm cast iron steel
The large, glass-bead blasted grinding discs made of hardened cast iron steel (64–66 HRC) produce exceptionally uniform particle distribution – the basis for high, clean extractions with fewer off-flavors.
True all-rounder
From Turkish-fine to espresso to filter, French Press or Cold Brew: the stepless adjustment covers almost every brewing method.
Stepless with zero point
The grind size adjustment runs steplessly and without a grid; the zero point can be recalibrated – so you can find every setting precisely again.
Vertical discs, low retention
The vertically arranged grinding discs are easily accessible and retain hardly any ground coffee – which is beneficial for single-dosing.
High grinding capacity, compact
With 19–21 g/s, the EK43 S works quickly, but requires significantly less counter space than the classic EK43.
Long service life
The grinding discs are designed for a throughput of around 6000 kg – a grinder for many years of operation.
When brewing, there is no "right" or "wrong": grind size, dose, and ratio are adjustment screws with which you can find your taste. For espresso, 1:2 is a common starting point, i.e., about 18 g of coffee grounds to about 36 g of espresso; in filter, the EK43 S demonstrates its uniformity particularly beautifully.

Roastery Tip
In a filter brew, the EK43 S showcases its clarity. We recommend Nutty Delight as a rounded all-rounder and Very Nutty as a strong, full-bodied filter; Cozy Chocolate remains chocolatey and dense in espresso. Those looking for a fruitier cup will discover a livelier side with Wild Peach or Bright Cassis. All beans can be found in our coffee bean selection. This is our recommendation, one of many.
