The Icon of Uniformity and Precision
The EK43 has become a global standard for coffee professionals due to its unmatched grind uniformity and clarity of flavor. Featuring massive 98mm flat burrs, a powerful motor, and extremely consistent particle distribution, the EK43 delivers exceptional extraction for espresso, pour-over, batch brew, cupping, and more.
Whether used in specialty cafés, roasteries, or serious home setups, the EK43 provides industry-leading performance with effortless control.

"Absolutely amazing machine. Very sleek, very consistent pulls, great steam power, the right amount of customization/settings control, etc. Build quality is exceptional as well. Would strongly recommend this machine to anyone looking for a high quality dual boiler machine that's simple, consistent, and sleek. 10/10"

It's as close to an absolute truth as you'll find in coffee, grind consistency is one of the most important variables when it comes to quality brews. As far as grind consistency is concerned you'll be hard pressed to find a grinder made to compete with the Mahlkoenig EK43 S other than its predecessor, the original EK43. Its rock solid build, wide range stepless grind adjustment, and huge 98 mm cast steel burrs all work in concert give you grinds a cut above the rest that means fewer fines, improved clarity, and the opportunity for higher extraction yields without unwanted bitterness and astringency.
With its wide range adjustment and the option to recalibrate your zero point, the EK43 S is capable of grinding for any brew method from Turkish coffee and espresso all the way up through batch brew, press pot, or cold brew. Whether you need a single-dose grinder for espresso or a bulk grinder that will handle batch brew and retail bags in mere seconds this machine is built for versatility in the cafe. Due to its shorter stature it could be a struggle to grind 5 lb bags or large batches for cold brew, but even then with some ingenuity you can rely on the EK43 S to deliver pristine grounds for any application. If using the EK43 S for espresso, or if you want to maximize performance potential beyond factory setup, Prima offers shimming and sanding burr alignment services with the purchase of a new grinder for an additional fee.
Mahlkönig is a name that's as synonymous with specialty coffee as most any other. Decades of experience that focuses on quality and innovation shine through in many of their products, from bulk grinders to grind-by-weight espresso offerings. It's safe to say that the premium quality you get in the EK43 S isn't by accident, but is a product of craftspeople who are as dedicated to quality as you are.
