Introducing the ARO Espresso™ Aluminum Grinder Setting Dial for Eureka Mignon, the ideal solution for achieving a precise and accurate grind setting on your Eureka Mignon, every time. Gain ultimate control over your espresso brewing process!

This product is designed specifically for the Eureka Mignon series grinders and is durable, reliable, and easy to use. It solves the problem of losing your reference point when switching between grind sizes. Now, you can easily adjust the grind size between espresso, pour-over, and French press grind sizes, and the numbered dial ensures that you can always return to your preferred setting with ease. No more wasting precious coffee to dial in the grind again!

The ARO Espresso™ Grinder Setting Dial and Adjustment Knob is a two-piece tool that is simple to install and will revolutionize the way you grind coffee in your Mignon. The grinder setting dial has 100 increments to ensure that you can dial in your grind size with precision. The grind adjustment knob is more ergonomic and easier to rotate than the stock knob. It uses a 3:1 gear ratio, which means three full rotations of the knob equates to one full rotation through all 100 increments on the dial. This unique feature allows you to make extremely fine adjustments and maximize the performance of your grinder.

Don't forget to pair it with our ARO Espresso™ Aluminum Single Dose Hopper to complete your set-up for the ultimate single dosing combo!

Key Features

• Solid aluminum adjustment knob: Aluminum is far superior to plastic for this particular application. The aluminum threads ensure the knob never strips, your grind setting never drifts, and will last a lifetime.
  
• Stunning laser engraved aluminum faceplates: With a minimalistic design, matte black finish, and precision laser engraved text, you'll forget that the grinder didn't come stock with this beautiful piece!
• Non-marring and non-invasive installation: The faceplates are set into a protective plastic housing containing the gear mechanism. This ensures a scratch-free installation while promising smooth and quiet operation.
• Matching single dose hopper (optional add-on): Elevate your single-dosing experience and add-on a single dose hopper and silicone bellows that integrates flawlessly with the dial for a unified and seamless look. Available in both premium aluminum and economical plastic.

Set-Up and Use

Installation is a breeze – it's a non-invasive tool that won't damage your grinder and you can remove it at any time. To install, just follow these quick steps:

1. Begin by emptying and removing the hopper from your grinder. You may need to loosen the screw on the back of the grinder inlet, but there's no need to fully remove it.
2. Clean any grounds from the grinder inlet and off the top of the machine.
3. Unscrew the stock adjustment knob by twisting it counterclockwise until it completely unscrews and can be removed from the machine.
4. Twist on the new grind adjustment knob and tighten it until the knob bottoms out and you feel resistance.
5. Find the 'zero' point on the grinder (read all additional details below*) with the new knob by turning on your grinder and slowly twisting the knob towards the FINE setting. When the burrs make first contact and begin to "chatter," immediately stop tightening the dial and back it off 1/16th of a turn or until the chatter stops. This is your 'zero' point.
6. On the dial, rotate the gear with the numbers so that '0' is directly under the arrow.
7. Position the dial over the grinder inlet with the arrow pointing towards you and press down until the dial contacts the top of the machine.
8. Insert your hopper back into the grinder inlet on the top of the machine.
9. Secure the hopper by tilting the back of the dial upwards and off the machine so that the hopper installation screw is visible. Use a Phillips head screwdriver to tighten the screw.
10. Press the dial back down onto the top of the machine.

Congratulations! You have successfully installed the ARO Espresso™ Grinder Setting Dial and Adjustment Knob. Enjoy the ability to effortlessly dial in your grind settings and get the perfect grind every time. 

To dial in your grind, we recommend beginning with these ranges and adjust as needed:

• Turkish: 0-5
• Espresso: 5-15
• Moka Pot: 15-30
• Drip/Pour-Over: 20-40
• French Press: 30-70

To be more specific, moving one increment on our dial requires 10.8 degrees of rotation of the knob. This corresponds to 24 microns of adjustment per increment on the dial. Rotating the dial a full rotation (from 1-100) adjusts the burrs by 2400 microns.

Consider factors like grinder model, bean type, and bean age, as they may require adjustments beyond these starting points.

What's in the Box?

• Optional add-on: Plastic single dose hopper with silicone bellows

Care and Maintenance

For daily maintenance, simply brush off any loose grounds and/or wipe clean with a cloth. 

When it's time for a more thorough cleaning, remove the dial and knob. Brush off the dial or use compressed air to blow away dust and coffee grounds. Do not submerge the dial. The knob can be submerged and cleaned with soapy water. Be sure to rinse well and dry immediately. Not dishwasher safe.

If you purchased a single dose hopper, these components can be removed from your grinder and hand washed with lukewarm water and soap. Be sure to rinse well and dry immediately. Not dishwasher safe.

Other Useful Info

A note on grinder cleaning: To remove the top plate of your grinder for cleaning, you'll need to temporarily remove the geared knob due to its larger diameter. Upon reassembling your grinder, simply reinstall the knob and recalibrate to your 'zero' point as outlined above. While this extra step may initially seem cumbersome, it's a recommended practice to perform the dial-in process each time you disassemble your grinder for cleaning. Plus, with the enhancements of this dial, pinpointing your 'zero' setting and dialing-in your grind setting takes under two minutes. The day-to-day convenience of always knowing your precise grind setting significantly outweighs the occasional need to remove the knob for cleaning.

The aluminum single dose hopper can be purchased here on its own. Its adjustable accent sleeve ensures a clean look with or without the dial. If you're interested in only the plastic single dose hopper, please contact us directly. Note that the plastic hopper is designed to work exclusively with the dial, as it lacks an adjustable accent sleeve, leaving a visible gap between the hopper and the grinder without the dial.
