MiiCoffee DF54 Single Dose Coffee Grinder (Black)

1 Month Update: I still really love this grinder. Best value purchase for the grind quality you get. After about 1-2 weeks of use, I noticed more static in the grinds, but a simple clean with the included chute brush resolved this and it's back to clean static free output. I've also started to spray my light roast beans, but not necessary for dark to medium roasts. I still love the look and how sturdy yet quiet it is. I also recommend hot starting for grinding to help maintain grind consistency. No clogging issues whatsoever. You can't go wrong with this grinder if you're looking for something for home that provides a quality grind to elevate your espresso journey. Original review: I wasn't one of the early adopters of the DF54, so I had to wait for the next batch shipment to be available so I could get my hands on one. My previous grinder was a Baratza Encore that barely met standards in terms of a good espresso grind (very inconsistent, muddy flavors), which it wasn't really designed for. I've read some of the complaints of the DF54 in terms of the zero point and static issues and I have to say so far I have none of those issues. Maybe they tweaked the manufacturing to address some of the prior issues to improve Quality Control on these latest arrivals. 1. My DF54 right out of the box hasn't had any static issues yet, even when grinding light roasts (which tend to have more static than darker roasts). 2. The Zero Point was spot on. Just turning the dial a hair past "0" was where the gear "chirping" happened, so I'm happy with this calibration. 3. First few grinds had a little bit of retention, but after that and using the bellows, the final grind comes to +/- 0.1g from the initial beans dosed. 4. Some video reviews talked about how the bellows come off too easily from the grinder, but with mine, the bellows are fairly snug that if I try to remove them, the "anti-popcorning" cap slips out with it, so seems everything fits well together. I haven't check the burr alignment on this unit, but so far I don't feel like I need to. For Espresso grinds, I have it set in the vicinity of 20, and my shots so far have produced wonderful clarity for fruity notes, but enough smoothness for flavors like vanilla. Very satisfied with my purchase. I really love the compact design, the quiet operation and pairs well with my Bambino Plus. I'll provide an update in 1 month.

At this price point, this kind of redefines the home coffee game. If you want to try dosing your beans and grinding immediately before brewing, but aren’t ready to commit two-to-ten times the cash to do it, this might be your destination grinder. I’ve watched the online reviews and they seem very picky about very fine variations in espresso shots, or a few seconds of grind time, or very slight differences in the percentage of fines. Ignore that stuff. I was planning to be mildly disappointed. If that’s important to you, this probably isn’t your end of the market. I think for most people, that’s an insane upsell for people moving up from canned coffee. Let’s be realistic: this is a flat burr grinder, with a small footprint, that can grind consistently from fine powder, through espresso, aeropress, filter, and drip, all very consistent and repeatable. You can switch settings easily between batches, going from morning drip to evening espresso without having to clean out the machine. It’s stepless with clear markings so you can switch settings and return to them later easily. It has an anti static feature like a much more expensive grinder so you don’t have to spray your beans every time. The workflow is really quite convenient. The clear dosing cup is a positive feature because you can see the grounds in the portafilter. It makes minimal mess. It’s competitive with grinders like the Niche Zero, and it’s potentially better, especially if you do espresso, for less than half the price. This is an excellent grinder. I have some minor annoyances. The forks for holding the dosing cup or portafilter are like a stiff silicone so are slightly floppy and less positive than I would like. It’s better than something like ABS plastic that you’d find on something from the big box. I got used to it quickly. People complain about the bellows being loose, but this hasn’t been a problem. The lid on mine is looser than the bellows so the lid comes off first unless I specifically pull off the bellows. Tapping the bellows a few times at the end of the batch to expel grounds just becomes habit, so I don’t think about it. There’s a small cutout for the cord on the bottom, so when I pick it up to clean the counter, it never wants to sit flat until I run the cord through the cutout. No big deal. It’s not super fast, but we’re talking something like 20 seconds, versus 10 seconds to grind a typical 18 gram dose? This isn’t meant to be a commercial grinder and I’m usually waiting for my machine to heat up anyway. I just think the complaints are minor for what you get.

Coming from a Capresso Infinity and then Breville Smart Grinder Pro, and having spent some time with a gen 1 DF64, I wanted a grinder that would allow me to switch between espresso and pourover, and regular and decaf beans from drink to drink. One grinder for everything. The DF54 is an appealing option as it's affordable, single dose, stepless, and compact. At first I really liked this grinder. It's small! It's quiet! It makes incredible espresso! However, after making a few drinks the grinder clogged on some dark decaf beans. After a thorough cleaning it clogged randomly. Medium roast espresso grinds did best, but I also experience clogs on some medium roast Blue Bottle Beans (at 5am! The worst possible time!). Other users complain about clogs as well - see Youtube user CaffeMartellaSingapore's video on Feb 15, he shows that simply by dosing an extra 7g of beans his DF54 clogs. The reddit r/df54 sub is absolutely chock full of people complaining about clogs, this is not an isolated issue. While the coffee this grinder makes is excellent, and the small size, low price, and quiet operation would make it ideal for home use, the clogging is incredibly frustrating. After agonizing over options I finally ordered a DF64 and while it's larger, much louder, and more expensive, I would strongly recommend it over the DF54. It handles the same beans at the same grind settings with alacrity. Far more confidence inspiring, and lower retention. My unit might just be a dud, as plenty of people don't complain about clogging, and the Turin grinders seem to suffer from quality control issues. If the DF64 didn't exist I would keep this grinder as an espresso grinder and use a different grinder for pourover. However, given that the DF64 does exist, costs the equivalent of a few bags of coffee more, and performs tremendously better, just buy a DF64. Pros: Excellent espresso Compact size Stepless adjustment Low retention Very quiet operation Cons: Small dose size Slow grind speed Static-prone plastic dosing cup Terrible clogging issues make it extremely unreliable to unusable. Two week update: I bought a DF64 and making 8 double shots a day with a variety of dark and light, cheap and expensive beans - zero issues whatsoever. Just some static and it's a bit loud. No clogs, no retention, I haven't had to disassemble anything. Tremendously less finicky than the DF54. Which is too bad, because if the 54 worked reliably I'd keep and recommend it. Six week update: DF64 has never had a single issue. I have also been experimenting with a Kingrinder K6 originally bought for travel, but find that it works incredibly well for espresso. Zero retention, easy grind adjustment. If you're just beginning with espresso I would recommend a good hand grinder. It's far easier to learn with than a cheap electric grinder. I would take a K6 over a DF54 if I were on a tight budget. Four month update: the DF64 has clogged once in four months, where the DF54 clogged at least half a dozen times in two weeks. Same users, same coffees, same workflow.

My previous grinder was conical and not bad to start with. However, it does not go fine enough for good espresso. I decided to buy this one as a replacement and I can't be happier with it. It is built of metal like a tank and I don't doubt that it will last. Even the power cord is wrapped in flexible high quality insulation. I only wish it had a 30 second power cut-off timer so I can leave it be and focus on the coffee machine in the meantime. It is very easy to use and much quieter than my conical grinder. It produces unifomr grounds which make tasty espresso even with my inexpensive De'longhi ECP3420. I upgraded to a bottomless portafilter and that brought my morning espresso an extra notch up. My main gripe with the morning espresso procedure now is to run it while sleepy. I use medium and dark roasts. The medium roast never produced a static field with either of my grinders. The dark roast used to make very bad static with my previous grinder, but a tiny spray of water on the beans removed it entirely. This grinder does not exhibit static with either roast type but I still toss a wet hand on the dark beans just in case. I can imagine how messy static can be given the cup does not close around the exit chute. The motor is plenty powerful and sounds the same regardless of whether idle or grinding. No signs of struggle.

Getting this grinder was exciting with its sleek design and 54mm conical burrs. What stopped me from keeping this grinder was the static electricity it produced with medium roasts. The coffee really stuck around the shoot of the grinder and would make a mess often enough to turn it in. Very good grinding of coffee though. The consistency in the grinds was plausible and the zero retention was very pleasing as well. I couldn't quite get it right for my moka pot though, but maybe that's not a big deal for most people looking to put it on their espresso bar. It would almost get five stars if it wasn't for the anti-static electricity function not working at the roasts I was using. I also did grind some darker roast coffee and the grinder did do well in eliminating the static electricity from it with no coffee sticking to the shoot for it in that case of a darker roast. Overall I would say it just needs to work for canceling out the static electricity for all roasts and it would really stand out!

Excellent, solidly built and easy to use grinder. Bought to replace a Fellow Opus grinder which had problems with grind retention. This grinder blows it out of the water. I use for Espresso only. Much more consistent grinds with very fine adjustment that is stepless and easy to use. The bellows easily clear any remaining grinds out of the chute after a grind finishes. Kit includes a brush to periodically clean the grind shut to prevent buildup. So far in several weeks of use I have seen minimal buildup. Retention - almost nonexistent, we're talking fractions of a gram at most. Consistency - incredible. Shots have been pulling consistently once I dialed in the grind size. Noise - Much quieter than the outgoing Fellow Opus. More of a low hum than a high pitch shriek. Operation - Easy, single dose loading into the bellows, single power button that is either on or off. Bellows are easily removed to access the bur assembly. Grinder can grind into a 58mm portafilter directly, or into the included grinds container, which is also sized to fit perfectly into a 58mm portafilter for grounds transfer. TLDR - Buy this, it simply cannot be beat at this price point.

Really happy with this, but it comes with a learning curve. I started too fine and immediately clogged it up and had to clear it. Every one of these is zeroed differently, so you'll have to take the time to find true zero and a setting that works for your coffee. Took about an hour to get to a working point to start dialing it in, but "dialed in" can be subjective. Retention performance is really good - I'm almost always getting out within 0.1gm what I put in. Also isn't as noisy as I thought it would be and doesn't wake anyone upstairs.

I've used this grinder at least once a day for over a year now. I wouldn't buy this one if I had to make the purchase again. I am grinding beans for drip coffee. Grind is consistent and this machine works pretty quickly when the chute is clean. My issue with this machine is the mess it makes and how easily the chute clogs. Out of the box this will work for a few weeks with no issues. However, if you don't keep up with cleaning the chute, it will clog up and block the chute. I've found that I have to push the bellows down quickly to blow out the chute a couple of times during the end of each grind. This keeps the chute clear enough so I don't have to take the grinder apart to clean it every day. Doing this blows grounds all over the counter. So not only do I have to clean the machine more often than once a week, There's grounds all over the counter that need cleaned too. I was hand grinding my beans every day. I guess this machine is better than doing that but it fell short of the experience I had hoped for.

Absolutely amazing grinder for the money. Too bad my cat ate the rubber portafilter holder while I was away 🥹

After a lot of research on which coffee grinder to buy, and after using the Sage Smart Grinder Pro for a few months, I decided to buy the DF54. Since I only use lighter-roasted Specialty coffee for espresso, the Sage Smart Grinder Pro did not work well. It is good for normal medium or dark-roasted coffee purchased from the supermarket, but with light-roasted specialty coffee it often got stuck (choked), sometimes it could not grind the coffee finely enough, and if it succeeded, it was on setting 1-3 out of 60 available (with the internal setting on 3 out of 10 degrees, he couldn't do less than that because otherwise, the conical burr touched one from the other). In addition, it had a huge retention (0.5-1.0g), unacceptable, until I got an excellent bellows by Fused Line (then retention was from 0.1-0.3g without cleaning, but inside the grinder always stays 2-3g of old coffee). However, to get to the point of this review, because of the above, I decided that I don't want to have these various problems anymore and I was thinking about the DF64 or Niche Zero model, which is currently a bit out of my price range. However, in these few months, DF54 appeared and since then I looked at all possible reviews, and concluded that it could be the one I wanted. Even though I came across several negative comments, especially on Amazon, I still ordered it as soon as it was available. Since it is apparently in high demand, I had to wait more than a month for it to be delivered, but that's fine. I've had it for more than a week now and so far everything is flawless. I hope it will stay that way for at least the next couple of years. So far it hasn't had any problems with choking, although I only use various light to medium-roasted single-origin specialty coffee. On average, I grind for espresso on a setting between 12 and 20 of 90 settings, depending on the type of coffee. So it can grind much finer than it grinds now. Retention during the first grinding (new grinder or after cleaning) was approximately. 0.3g, everything after that is practically zero, or sometimes 0.1g, all with a few pressures on the bellows. Without the use of bellows, it is about 0.1g. That's a great result for any grinder, especially after experiencing of using the Sage grinder. With humidity in the apartment between 40-50%, I have no problem with static electricity and the grinder is really clean. It dispenses coffee very consistently, without lumps. It works pretty quietly while grinding, and almost silently without coffee. And when it is without the lid, it does not throw the beans or anything inside out thanks to the anti-popcorn disc. I've seen many people comment in video reviews that the bellows fall off easily, but that's not true. Because the bellows have different sides, up and bottom sides, and the difference is visible from the inside, so if it's positioned as intended, it won't fall off the top of the grinder. In any case, I can't find any flaws so far. I hope it will remain so in the future. In addition to all of the above, I brew coffee on a Gaggia Classic Pro (built-in PID and variable preinfusion, 9 bar springs, and IMS Competition and BigBang baskets), and I can only say that with this grinder, the coffee is incomparably better, creamier, better body than before with other grinders. The conclusion is that this (after ten days of use) is a superb grinder for a very affordable price. And the DF54 grinder's build and look are exceptional. 07/2025 UPDATE after a year of using: After more than a year of using this grinder, I can confirm that everything still works perfectly. A few months ago, I checked for the first time the gap between burrs, and it was pretty balanced. I do a very small correction on one side, but nothing significant. I just need to put 2 small pieces of aluminium foil below the screw of the burr on the upper part of the grinder, that one that had no rotation (you can see it in the picture). But that is normal when using this grinder daily, at least a few times per day. Note: I use only high-quality specialty coffee, light to light/medium roasted, so the coffee beans are slightly harder than regular coffee, but so far without any problems or burr choking. I hope that all remain the same in the future. I highly recommend this grinder.

Oggetto di design ..pesante ben assemblato..ero dubbioso sulla macinatura fine per espresso viste le recensioni ..invece ottima resa con filtro a pressione e tacca 10 adesso proverò il cestello IMS con portafiltto vuoto per esaltare la schiuma..caffe in grani dark della Costarica

Tocó jubilar a mi Baratza Virtuoso+, sin embargo no podría estar más encantado. La calidad de construcción es excelente, es robusto, pesado, pero requiere poco espacio. El unico punto donde podría mejorar es en cable, ya que si se siente de una calidad mas baja (Tomando como referencia el cable del Molino Baratza). Pros: - Practicamente 0g de retención. - Se pueden percibir notas en el café con mayor claridad (Espresso y filtrado). - Es rápido comparado al baratza. - Hace poco ruido. - El Ionizador funciona perfecto, no se hace un desastre. - El "Anti popcorn" funciona muy bien, no se andan saltando los granos. Puntos de mejora: - El cable si se ve medio chafa, la verdad. - No viene un manual donde te diga que rango se recomienda para prensa, filtrados y espresso. - El punto 0, no es en realidad el 0, tienen desfase de fábrica. En el mio el 0 esta en el -5. (No es un problema que haga malo este molino, hay piezas impresas 3D para corregir esto). - Si lo pensabas usar para filtrado, puede que no sea el mejor, ya que su muelas estan mas pensadas para espresso y crea bastantes granos finos. (Hay una técnica llamada "Slow Feeding" que ayuda a la uniformidad). Notas: - Toma en cuenta que podria taradar bastante en llegar, el mio tardo casi un mes.

Bra kvalitetskänsla. Ingen statisk elektricitet när man maler. Exakt dosering, lätt att få ut allt malt kaffe. Maler riktigt fint, med god marginal, har aldrig behövt gå ner på finaste malgraderna. Passar väldigt bra för espresso.
