MiiCoffee DF64 II

The DF64 platform has been a staple for home baristas seeking uncompromising grind quality and this iteration, the DF64 II, elevates the experience. Its focus on meticulous engineering for consistency and minimal retention targets the demanding coffee enthusiast. This grinder promises café-level precision for serious home brewing.

TECHNICAL BREAKDOWN

• Version 2.5 Improvements: The critical upgrade lies in the revised inner chute design. The plasma generator probes now discreetly wrap around the inner chute, a significant improvement over the older version’s internal probe placement. This design refinement aims to optimize particle flow and static reduction more effectively, minimizing potential snag points.
• 64mm Flat Burrs: Equipped with custom-made 64mm stainless steel flat burrs, this grinder delivers exceptional grind consistency, crucial for even extraction. The flat burr geometry is renowned for producing a uniform particle distribution, ideal for espresso. The option to upgrade to SSP burrs provides a pathway for users to further tailor their coffee’s flavor profile, exploring clarity, body, or sweetness nuances based on burr geometry.
• Single Dosing & Zero Retention: A cornerstone feature, achieving true zero retention, typically less than 0.1 gram. This is paramount for single dosing, ensuring the precise dose in equals the precise dose out. The grinder achieves this impressive retention without relying solely on a bellow, indicating superior internal design. The included blow-out funnel with lid further guarantees complete clearance of residual grinds, vital for maintaining freshness and preventing flavor contamination between doses.
• Plasma Generator (Ionizer): Integrated within the exit chute, the plasma generator actively neutralizes static electricity. This technology is critical for a clean workflow, preventing coffee grounds from clumping or adhering to surfaces, which can lead to mess and dosage inaccuracies. Its placement within the chute, especially with the V2.5 design, aims for maximum efficacy.
• Stepless Adjustment: The redesigned dial, wrapped in chrome with an included metal indicator, offers infinitely variable grind size adjustment. This stepless mechanism allows for minute, precise changes, indispensable for dialing in espresso shots where even fractional adjustments can significantly impact extraction time and flavor. The tactile feedback and visual indicator enhance the user experience for fine-tuning.
• Anti-Popcorn Disc: An integrated anti-popcorn disc is crucial for consistent feeding of beans into the burrs. By preventing beans from jumping, it ensures a steady grind rate and minimizes variations in grind consistency, which can occur when burrs are not continuously fed. This also contributes to faster grinding times by optimizing bean flow.
• 58mm Aluminum Dosing Cup: A high-quality, food-grade aluminum dosing cup is included. Its 58mm diameter is industry standard, allowing direct transfer to many portafilters. While a portafilter can be rested, the cup is recommended, especially for non-58mm portafilters, promoting cleanliness and precise dosing without spillage.
• Voltage: Designed for the US market, it operates at 110V with a standard US plug, ensuring compatibility with most household electrical systems.

THE REAL-WORLD PERFORMANCE

In practical application, the DF64 II consistently delivers exceptional grind quality, immediately evident in the espresso extraction. The uniform particle size from its 64mm flat burrs translates into predictable shot times, exhibiting excellent temperature stability throughout the puck, and resulting in balanced, sweet flavors with notable clarity. Crema production is consistently rich and dense, indicative of a well-extracted shot free from excessive fines or channeling, thanks in part to the effective static reduction and near-zero retention ensuring fresh grounds for every dose.

WHO IS THIS FOR?

This grinder is for the meticulous home espresso enthusiast or serious pour-over brewer demanding precision, consistency, and minimal retention.
