DF54 Single Dose Coffee Grinder (Black)

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.

I couldn't be happier with this grinder. It features 54mm flat burrs, which are compact yet effective for delivering a range of grind sizes suitable for espresso to pour-over. The grinder offers a stepless adjustment dial, allowing for precise control over grind size without preset steps. This level of control is beneficial for dialing in espresso shots and achieving finer adjustments than typical stepped grinders.One of the standout features of the DF54 is its built-in de-ionizer (plasma generator), which reduces static build-up, helping to minimize clumping and retention, an important factor for single-dosing grinders. Retention on this model is low, generally around 0.1–0.2 grams, thanks in part to the optional bellows, which also assist in clearing the grinder's chute after each use. Additionally, it includes a 58mm dosing cup that fits standard commercial-style portafilters, making it convenient for direct dosing into espresso machines.The DF54's design is solid with a powder-coated aluminum build, available in black and possibly white, weighing around 10 pounds. Its compact form factor and affordable price (just over $200) make it an attractive choice for home baristas looking to enter the world of precise espresso grinding without breaking the bank.

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.
