Mahlkonig EK43 ST Coffee Grinder

A Mahlkönig EK43 ST with 98 mm burrs grinding at approximately 25 g/s on a single-phase supply, weighing 24.5 kg. Twenty-five grams per second is extraordinary throughput — this is the grinder roasteries use to fill retail bags and cafes use for batch brew, not a machine for dosing single espressos.

Who it suits

For roasteries grinding retail orders, cafes running large batch brew volumes, and any operation where grind uniformity across coarse settings matters. The EK43 has become a reference machine in specialty coffee for exactly that uniformity. It is not an espresso dosing grinder, and using it as one wastes both the machine and counter space.

Common questions

Why is the EK43 so widely used in specialty coffee?
Its grind uniformity across coarse and medium settings is the reference standard for filter and batch brewing, which is what roasteries and competition brewers need.

Is 25 g/s useful for espresso?
Far more than needed for a single dose. The speed matters when filling retail bags or batch brew hoppers.

How does the ST differ from the standard EK43?
ST is a specific variant in the EK43 family. Compare the dosing and adjustment details against your workflow.

How heavy is it?
24.5 kg net, so it needs a permanent bench position.
