KM Single Dose Hopper for Eureka Mignon Grinders

Haptics & Design:

• The lid: Plastic. It sits securely in your hand, which is important so it doesn't rattle from vibrations during grinding.
• The bellows: Durable silicone. It feels grippy and has just the right resistance to build up proper air pressure.
• The fit: We tested it on our Mignons. It fits perfectly on the entire series (Specialita, Manual, Classico, Silenzio, Design, XL, etc.).

Specifications:

• Material: Plastic (lid & base), silicone (bellows)
• Dimensions: approx. 79mm diameter, 107mm height (fits under almost any kitchen cabinet)
• Compatibility: Eureka Mignon series (Manual, Magnifico, Classico, Specialita, Perfetto, Design, Silenzio, Filter, Crono, Brew Pro, XL)
• Capacity: Ideal for single dosing portions (up to approx. 50-60g beans)

The Workflow:

How does this work in practice? You weigh out your dose – let's say 18 grams for a double espresso – and pour it into the hopper. The grinder runs empty. Normally, coffee grounds would stick in the chute at this point (what we call retention).

Now comes the "blow-up" effect: You press down firmly on the silicone bellows a few times. The air blast actively pushes the remaining coffee grounds out of the grinding chamber.

Our Measurement:

• Standard hopper: Often up to 2.5g retention (depending on roast level and static charge).
• With single dose bellows: We almost always achieve input = output. If we put in 18.0g, we get 17.9g to 18.0g in the portafilter. That's a quantum leap for cup consistency.

Critical View: What You Should Know

Is everything perfect? Not quite. Since there's no heavy bean pressure from above, the beans tend to "pop" more during grinding – they bounce around a bit more wildly in the grinder. This changes the grinding noise and can extend the grinding time by a few seconds. But: the result in your cup is absolutely worth it. You get maximum freshness and can switch bean varieties anytime without waste.

Verdict: Is the Upgrade Worth It?

Who is this for? If you pull 10 identical espressos in a row every day: stick with the standard hopper. But for all home baristas who love to experiment, drink espresso in the morning and filter coffee in the afternoon, or simply don't want to waste 3 grams of coffee every morning (by "purging"), this kit is a clear recommendation.

We've rarely seen an accessory that upgrades a grinder so significantly for such a fair price.
