Who This Grinder Is Built For
The DF64 II targets home baristas who already weigh their coffee and want a dedicated single dose grinder rather than a hopper-fed machine. It fits people brewing both espresso and pour over from the same unit, since the 64mm flat burrs handle fine and medium grinds without swapping parts. It also appeals to anyone who likes tinkering, because the DF64 platform has a large aftermarket following, so replacement burrs and modification parts are easy to find later. Beginners who only want to press a button and walk away may find the dial and weighing routine slower than a hopper grinder, but anyone chasing consistent shots from a rotating cast of beans will appreciate the control. Cafe workers looking for a compact backup grinder for pour over service also fit this grinder well, given its focus on low waste single dosing rather than high volume batch grinding.
Burrs, Settings and What Ships in the Box
At the core sit custom made 64mm flat stainless steel burrs designed to produce a fluffy, consistent grind with fewer clumps than many conical designs. The dial offers around 90 marked positions but is fully stepless underneath, so you can land between numbers for fine tuning. The hopper area is small by design, holding about 30 grams of beans without the optional bellow attached, or up to 80 grams with it fitted, since this is a single dose grinder rather than a bulk hopper unit. An ionizer built into the exit chute cuts down static so grounds fall cleanly into the dosing cup instead of clinging to the walls, and an anti popcorn cover on top helps keep beans settled during grinding. A 58mm aluminum dosing cup ships in the box, ready to use under most standard portafilters.
Living With the DF64 II Day to Day
Retention is the headline feature here, with MiiCoffee rating true zero retention at under 0.1 grams even without the bellow fitted, which matters if you rotate between different beans often and do not want old grounds mixing into a new roast. In practice that means you weigh beans into the chute, grind, and tap out a dose that closely matches what you put in, with little cleanup between switches. The static reducing ionizer noticeably cuts down on grounds sticking to the chute walls and dosing cup compared with grinders that lack this feature. Because the body stands about 12 inches tall on a 10 by 5 inch footprint and has real heft to it, you need a fixed spot with clearance under upper cabinets, since it is not a grinder you want to shuffle around a shared counter daily.
Trade-offs and How It Stacks Up Against Rivals
Against the top ranked Turin DF64 in the same best single dose grinders guide, the DF64 II lands just behind on overall score, and the two share a lot of design DNA as members of the same grinder family, so the choice often comes down to price and small finish details rather than a huge performance gap. Compared with MiiCoffee's own smaller DF54, the DF64 II grinds faster thanks to its larger 64mm burrs and has a deeper pool of aftermarket burr upgrades, but it also costs more counter space and requires a firmer surface to sit on. The main day to day trade-off is the stepless dial itself: because there are no hard detents, you need to mark your own settings with tape or a marker to return to a favorite grind reliably, which is an extra step hopper grinders with numbered clicks do not require.
Verdict: Who Should Look Elsewhere
For a home espresso or pour over setup where you already weigh beans and want low retention grinding from 64mm flat burrs, the DF64 II earns its spot near the top of the single dose category, backed by a wide community of parts and upgrades. Shoppers with limited counter depth or a tighter budget may prefer the smaller MiiCoffee DF54, which trades some grind speed for a smaller footprint and lower cost. Anyone who wants a simple numbered dial instead of stepless adjustment, or who grinds straight from a full hopper rather than dosing bean by bean, will likely be happier with a different style of grinder entirely.
