Grind for Multiple Methods

The Eureka Atom espresso grinder is well suited to far more than just espresso! Eureka brand grinder's engineers conceive their burr sets to offer grinding abilities suitable for the preparation of both espresso and filter coffee brew methods.

Grind by Weight

Grind-by-Weight technology gives you the option to program to 0.1 gram settings, moving away from the previous grind-by-time grinders. This will give you better dosing accuracy and repeatable results. It will easily measure out the weight of the espresso dose accordingly.

Touchscreen Features

The touch screen on the Mignon Libra espresso grinder features a large screen so that you can adjust your grind setting and insert your programmable doses.

Programmable Shots

You have the ability to customize your coffee by programming the shots to dispense a specific amount of coffee grounds. This allows for consistent results in every grind, whether you're making a single or double shot of espresso.

On Demand Grinding

This Eureka coffee grinder is an on demand grinder and capable of grinding for your portafilter at the touch of a button. 

55mm Flat Burrs

The 55mm burr size strikes a balance between being large enough to deliver consistent and precise grinding, yet not overly bulky. These are made for high productivity and can perform an espersso shot at 1.4-1.8 grams per second.

This makes it ideal for prosumer setups (enthusiast-level home espresso machines) and low-to-medium volume coffee shops. 

Ace System and Anti-Clumping

The burrs large size isn't the only feature reducing retention, improving flavor, and providing incredibly fluffy grind. The ACE System by Eureka is an anti-clump and electrostatic system that prevents the development of clumps and eliminates electrostatic charge that's created while grinding coffee. Eureka grinder's unique anti-clumping system creates a beautifully fluffy grind even with the finest of espresso grinds.

Zero Waste Grinds

Achieving Zero Waste is made possible by: 1. A special Anti-Vibration System that enables uninterrupted shots even when there are disturbances or impacts on the filter holder. 2. The exclusive IGW Technology ensures that the grinding process halts immediately when the filter holder is removed.

Stepless Adjustments

The Atom coffee grinder is not only a beautiful and quiet espresso grinder, but it is also effortless to use. With its simple grinding adjustment, a stepless ring nut gear makes it easy to make minuscule grind adjustments. Something that every barista knows is the key to a great espresso!

Silent Technology

This Eureka machine's Silent Technology offers a unique solution to minimize vibrations and significantly decrease grinding noise levels (approximately 64 dB), ensuring a peaceful and enjoyable grinding experience at all hours.

Dosing Funnel

What adds a little extra to the Eureka line is the thought of a dosing funnel. You will find this metal funnel with your machine for less mess grinding.
