Who it fits

MiiCoffee DF64 II Key Specs

Burr Size: 64mm

The burrs measure 64 millimeters across. This size offers a balance between grinding speed and consistency. Larger burrs typically grind faster than smaller ones. You get a steady flow of grounds. This size is common in mid-range grinders. It suits both espresso and filter brewing. Check your budget against burr diameter for quality.

Burr Material: Stainless steel

The burrs are made from stainless steel. This material resists rust and corrosion. It maintains sharpness over time. Stainless steel burrs produce consistent particle sizes. This consistency is vital for even extraction. You will notice fewer fines in your grounds. Compare this to ceramic, which can wear differently.

Grind Settings: Stepless

The adjustment dial offers stepless control. You can make micro-adjustments to grind size. This precision helps dial in specific brews. Espresso requires exact settings for optimal flavor. You can tweak the grind without jumping settings. This feature benefits serious home baristas. Look for stepless dials for maximum control.

Dosing Control: Single dose

The grinder is designed for single dosing. You grind only what you need at the time. This method minimizes coffee retention. You avoid stale grounds sitting in the chamber. Freshness is preserved for every brew. This is ideal for varying bean types. Single dosing grinders often have low retention rates.
