Grinding Performance - Quiet Yet Powerful

The combination of the powerful 300W brushless DC motor and the 64mm diamond-like carbon (DLC) coated flat burrs ensures that the DF64V can handle even the most demanding beans with ease. The motor’s high torque allows for consistent grinding, while the DLC coating on the burrs reduces friction and heat buildup, preserving the coffee’s delicate flavors and aromas.

Variable Speed - Flexibility in Brewing

One of the most notable features of the MiiCoffee DF64V is its variable speed control. The 600 to 1800 RPM range gives you unparalleled flexibility to adjust the grinding speed to your preference. Whether you prefer a slower grind for more uniform particle size or a faster grind for efficiency, the DF64V has you covered. This versatility makes it an ideal choice for home brewers and coffee professionals who often experiment with different beans and brewing methods.

64mm DLC Coated Flat Burrs - Where Quality Meets Durability

The MiiCoffee DF64V is equipped with 64mm diamond-like carbon (DLC) coated flat burrs. These burrs are not only sharp and durable but also boast exceptional heat resistance. The DLC coating minimizes friction, ensuring less heat is generated during grinding, which preserves the delicate flavor compounds of your coffee beans. The result is a cleaner, brighter, and more flavorful cup of coffee.

Magnetic Grounds Chute - A Tidy Addition to Your Coffee Bar

The magnetic grounds chute of the MiiCoffee DF64V is a simple feature that makes a big difference. It securely attaches to the grinder, ensuring your coffee grounds go directly into your portafilter or container. This design eliminates mess and minimizes waste, making your coffee brewing experience more enjoyable and efficient.

Low Retention Design - Every Bean Counts

Coffee enthusiasts know how frustrating coffee ground retention can be. That’s why the MiiCoffee DF64V features a low retention design, ensuring less than 0.1 grams of coffee grounds remain in the grinding chamber. This efficiency means you can maximize the use of your precious coffee beans, especially when using expensive single-origin coffees.

Precise Stepless Grind Size Adjustment - Master Your Grind

With an impressive 270-degree adjustment range, the MiiCoffee DF64V allows for precise stepless grind size adjustment. This means you can fine-tune your grind setting to perfectly match your coffee beans and brewing method. Whether you prefer a superfine grind for espresso or a coarse grind for French press, the DF64V delivers the exact grind size you need with precision.

300W Brushless DC Motor - Powerful Performance, Quiet Operation

The MiiCoffee DF64V is equipped with a powerful 300W brushless DC motor that can effortlessly grind the toughest coffee beans without compromising speed or consistency. Despite its power, the grinder operates remarkably quietly, thanks to its advanced motor technology and sound insulation features.

Bellows Design - Minimizing Waste

The MiiCoffee DF64V takes the concept of low retention a step further with its unique bellows design. After your grind cycle is complete, a simple press of the bellows sends a powerful gust of air through the grinding chamber, clearing out any remaining particles. This ingenious mechanism ensures you get the most out of every precious coffee bean, especially when dealing with expensive single-origin coffees.

58mm Metal Dosing Cup - Convenience and Practicality

The MiiCoffee DF64V comes with a 58mm aluminum dosing cup, perfect for filling your portafilter directly with coffee grounds. The cup is thoughtfully designed to minimize static, ensuring a smooth transfer of coffee grounds without any mess. Even if your portafilter isn’t 58mm, this cup can serve as a temporary holding container, providing convenience between grinding and brewing.

Noise Level - Quiet Operation

Unlike many other grinders, the MiiCoffee DF64V is remarkably quiet during operation. This is due to its brushless DC motor and thoughtful sound insulation. Whether you’re brewing coffee in the early morning or preparing espresso late at night, you won’t disturb your family or roommates.
