Specs: Flat vs Conical Burrs
Burr geometry
The MiiCoffee 83mm Flat Burr Single Dose Grinder uses 83mm red titanium flat burrs. Flat burrs typically create a more uniform particle distribution, which many espresso enthusiasts prefer for clarity and sweetness. In contrast, the MiiCoffee 63mm Conical Burr Coffee Grinder features 63mm red titanium coated conical burrs. Conical designs often produce a broader particle range, adding body and richness to the cup. The flat burrs are larger, potentially offering longer life and consistent shear across a wider surface area compared to the smaller conical set.
Adjustment mechanism
The MiiCoffee 63mm Conical Burr Coffee Grinder offers stepless adjustment via a large dial. This allows you to make infinitely small changes, which is critical for dialing in espresso with high precision. The MiiCoffee 83mm Flat Burr Single Dose Grinder does not list a specific adjustment mechanism in its provided data. Without knowing if it uses stepless or stepped settings, you cannot assume it matches the precision of the DC63 model. The DC63 provides a clear advantage in adjustability transparency.
Static reduction
Both grinders address the common issue of static cling using the same technology. Each model includes a plasma generator, also known as an ionizer, located at the exit chute. This feature reduces static to non-existent levels for both the MiiCoffee 83mm Flat Burr Single Dose Grinder and the MiiCoffee 63mm Conical Burr Coffee Grinder. Additionally, both utilize red titanium burrs, which naturally have a low surface friction coefficient. This helps grounds slide off the burrs more easily, further minimizing mess and making cleanup simpler for both machines.
Retention and flow
Both grinders claim true zero retention of less than 0.1 gram. They achieve this through a blow-out funnel design with a lid to completely empty the dead space. The MiiCoffee 83mm Flat Burr Single Dose Grinder relies on this funnel system. The MiiCoffee 63mm Conical Burr Coffee Grinder uses the same funnel approach but adds a silicone press knocker to help clean residual grounds. While the retention numbers are identical, the knocker on the DC63 provides an extra manual step to ensure no coffee remains stuck in the mechanism.
Physical footprint
Size matters for your counter space. The MiiCoffee 83mm Flat Burr Single Dose Grinder measures 6 inches in width, 9 inches in length, and 18 inches in height. It is a taller unit. The MiiCoffee 63mm Conical Burr Coffee Grinder is more compact, measuring 4 inches in width, 6.5 inches in length, and 12.6 inches in height. The DC63 takes up significantly less vertical and horizontal space, making it a better fit for smaller kitchens or tighter setups where counter real estate is limited.
Additional features
The MiiCoffee 63mm Conical Burr Coffee Grinder includes an auto-stop function that stops grinding automatically when all beans are ground. It also comes with a 58mm metal dosing cup. The MiiCoffee 83mm Flat Burr Single Dose Grinder includes an integrated anti-popcorn disc to prevent jumping beans and increase grinding speed. It also provides a 58mm aluminum dosing cup. While both have dosing cups, the DC63 offers the convenience of automatic operation, whereas the DF83 focuses on mechanical efficiency through its anti-popcorn design.
Choose based on your grind needs
Espresso purists wanting maximum clarity
The 83mm flat burrs are designed to create a more uniform particle distribution. This geometry is often preferred by espresso enthusiasts for its ability to highlight coffee clarity and sweetness. The larger burr size supports this specific extraction profile for detailed flavor notes.
Users seeking precise dial-in control
This model features stepless adjustment via a large dial, allowing you to fine-tune settings from fine to coarse with high precision. This mechanism is ideal for dialing in espresso shots, ensuring you can hit the exact grind size required for your specific beans and machine.
Those prioritizing compact footprint and automation
The DC63 is significantly smaller, measuring 4 inches wide and 12.6 inches tall, compared to the larger DF83. It also includes an auto-stop function that halts grinding when beans are finished, and a silicone knocker for cleaning. These features suit users with limited counter space or those who value convenience.

What burr material do both grinders use?
Both models feature red titanium burrs. The 83mm version uses flat burrs, while the 63mm model uses conical burrs. This shared material choice suggests similar durability and heat resistance across both single-dose designs. The geometry differs, but the metal composition remains consistent between the two units.
Are both grinders available in black?
Yes, both models are available in black. The MiiCoffee 83mm Flat Burr Single Dose Grinder comes in black. The MiiCoffee 63mm Conical Burr Coffee Grinder also offers a black color option. You can match either grinder to a dark kitchen aesthetic without choosing a different brand.
Do these models include dosing cups?
