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!

- 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:
- 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.
- Clean any grounds from the grinder inlet and off the top of the machine.
- Unscrew the stock adjustment knob by twisting it counterclockwise until it completely unscrews and can be removed from the machine.
- Twist on the new grind adjustment knob and tighten it until the knob bottoms out and you feel resistance.
- 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.
- On the dial, rotate the gear with the numbers so that '0' is directly under the arrow.
- 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.
- Insert your hopper back into the grinder inlet on the top of the machine.
- 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.
- 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.

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.
I hesitated to get the Eureka Mignon grinder due to its very small and super sensitive grind setting dial. I've put up with a Mazzer-Mini Timer for two decades (!), a fine grinder but impossible to fine tune grinds due to it's sensitive adjustment wand. Did not want to go through that again. When I saw this ARO offering, I ordered it immediately. It came quickly, is well made with quality materials, nicely packaged and fits the ORO XL perfectly. And, by the way, it works perfectly and as advertised. It completes a very fine grinder and I could not recommend it more highly. Well done.
Super Service, Lieferung dauerte allerdings drei Wochen.
Bauteile sehr passgenau und wertig. Ich bin sehr zufrieden.
The standard Eureka Mignon can be very precisely dialed. BUT it doesn't have a good way of letting you know just how far you've adjusted the grind size. Did I turn the knob 1/4 turn to the left? Or was that to the right? Maybe it was 1 and 1/4 turn? Which way was "fine" and which way was "course" again? This knob lets you know clearly where you are at.
This dial upgrade takes out the guess work! And it gives me the confidence to adjust the grinder for much finer adjustments.
Do note that while the knob itself is aluminum (very well made and feels good to the touch), the collar that sits on top of the machine is plastic. However this isn't a negative to the product, as it isn't anything functional or load bearing other than as a display to indicate in clear lettering what setting you are at. It functions just great, and I'm sure if this part was also aluminum, it would make the overall cost $30-50 greater, with no additional benefit.
Installation was fairly easy, and the instructional video made it even easier. I found my zero by using a socket wrench to manually turn the motor counter-clockwise, while slowly setting the grinder finer and finer, until I heard/felt the grind wheels starting to rub against each other. I then set the dial to zero, and put it into place (the hardest part). Then put the hopper back in (be careful that your "bean gate" swinging door is closed while doing it, so you don't accidently break it off!). I'd recommend setting the machine to 20-25 before turning the grinder back on, to avoid the grinder heads inside from rubbing on each other, or making too fine of espresso. Between 20-25 should get you pretty close to where you need to be for a starting point.
If you like to try different coffee beans and different grind settings, this is a must have. It takes the guess work out of blindly setting your grinder, and gives you an easy reference for when you might go back and forth between different types of beans and brewing styles. Shipping by Aro Espresso was also fast and easy.
Finally, I'd recommend buying directly from Aro Espresso, instead of on the Amazon store. It ships a little faster, you can actually get it a little cheaper from time to time. And it puts more money in Aro Espresso's pocket, instead of Amazon getting a cut.
Also beware that there are other similar products on Amazon and elsewhere for just a few dollars cheaper. They do not have an aluminum knob (the part that IS load bearing), and not as clearly marked. I've read some reviews that the dial/plastic isn't the best quality either. And some even are not as compatible with different Eureka grinders as the ARO Espresso product. So save yourself some headache, spend the $3-4 dollars more, and get the superior Aro product instead. I'd highly recommend it to all Eureka grinder owners.
Lovely stylish combo here! The single hopper and the aluminum big knob, so useful and so easy to install! I wish that the aluminum hopper was already available, but the plastic also looks very durable. All in all a great purchase! :)
Well built and makes the grinder much more repeatable and versatile going between beans and brew methods
