Fellow Opus Conical Burr Coffee Grinder – All Purpose Electric – Espresso Grinder with 41 Settings for Drip, French Press, & Cold Brew – Matte Black

Amazing
I couldn’t be more thrilled with the Fellow Opus Conical Burr Coffee Grinder—it has transformed my coffee routine! As a coffee enthusiast, I’ve gone through a few grinders, but the Fellow Opus truly stands out with its incredible design, precision, and consistency. From the moment I took it out of the box, I was impressed by its sleek, modern look. It feels sturdy and well-built, with every detail thoughtfully designed.
One of my favorite features is the 40+ grind settings, which makes it super versatile for any brewing method. Whether I’m in the mood for a rich espresso, a balanced pour-over, or a bold French press, the Fellow Opus handles it all. The conical burrs ensure a uniform grind, which I can taste in the cup—the flavors are more vibrant, and the aromas more pronounced than with my previous grinders. It’s amazing how this one tool brings out the best in every coffee bean, highlighting notes I didn’t even know were there.
The grinder’s functionality is just as impressive. The dial for adjusting the grind size is easy to use, and switching between settings is seamless. Plus, it’s incredibly quiet, which is a game-changer for early mornings when I don’t want to wake up the whole house! I’ve had other grinders that sounded like power tools, but the Fellow Opus operates with a gentle hum that’s easy on the ears.
Another aspect that I appreciate is the Fellow Opus’s ease of cleaning. Taking it apart to clean is straightforward, and it’s simple to keep it in pristine condition without much effort. This is huge because consistent maintenance keeps the grind quality high over time.
Overall, I’m beyond happy with this grinder it’s worth every penny. It’s obvious that Fellow put a lot of thought into designing something that is not only aesthetically pleasing but also exceptionally functional. The Opus has become an essential part of my kitchen, and it’s completely elevated my coffee experience. I’d recommend it to any coffee lover looking for top-notch quality, precision, and a grinder that makes each cup a joy to brew.

Works well, looks good, but…
I like the Fellow design style. It’s simple, and unobtrusive.
I use the grinder for pour-over, AeroPress, and Moka Pot coffee making. Adjusting the grinder to the suggested appropriate settings works out well. Whether or not the Opus really gives a usable espresso grind is left for others to comment on. That’s the good news.
The receiver cup’s somewhat problematic. Fellow’s Ode grinder uses a strong magnet to hold the cup in place. For some reason, the Opus uses a weaker magnet than can be easily overcome, meaning the discharge from the grinder may or may not all go into the cup. Maybe this is nit-picking, but why Fellow used a magnet that doesn’t firmly hold the cup place escapes me.
While the Ode cup has baffles, to direct pouring the ground coffee, that upset at least one YT reviewer, the Opus cup uses flats in the interior to direct pouring. That works – mostly, A ring is fitted to the top of the cup, although I’m not sure I get why it’s used. Does Fellow expect ground coffee to billow out of the cup? Beats me. Anyway, the ring has to come off to pour out the ground coffee.
Over time, debris from beans builds up both on the actual burrs, and on the sloped floor of the grinder hopper. Someone came up with a silicon bellows that’s supposed to blow the debris through the grinder. Don’t bother, it doesn’t happen. Because the grinder and receiver cup are plastic, “static cling” is the big culprit here. Plan on misting beans with the least bit of water to manage this problem. Keep in mind “more is >not< better". Because of the plastic construction, and the need to take the hopper off for effective cleaning, I'm not sure how this will impact the grinder's service life. The same is true for the adjustment for grind size. There are definite clicks while adjusting the fineness. Again the question of wear and longevity comes to mind. The grinder has only one power control, a push button on the base of the grinder. Push it once, and the motor runs for 30 seconds, which should be more than enough for small batches (i.e., 1-3 cups). Run time can be increased with multiple button presses. The motor can be stopped by pushing the button while the motor's running. At least one YT review objected to the Ode grinder's beeping. It's easy enough to figure out when all the beans in a batch are ground; the motor speeds up noticeably. The same's true for the Opus - and it doesn't beep to announce the obvious. Or does it? For some reason, when the Opus is plugged in, it beeps once. So far, I haven't heard any beeps before, during, or after grinding. But any time I plug the Opus back in, it beeps. Huh? In the main, I'm pleased with the Opus. It's adjustable to different grinds, it works without significant annoyances, and I suspect it'll last for quite a while. It's the niggling details, such as the weak magnet, and the problems with clearing out debris that keep the Opus from a fifth star. A caveat about browsing on the Fellow website. If you look at a particular item on the website. expect to get at least a few IMHO nagging emails about "are you ready to buy [whatever]".

Después de meses de haber visto y leído reseñas de distintos molinillos para café, uno de los mejores (especialmente para espressos) fue éste, y a decir verdad estoy bastante contento con la compra. El aparato es ruidoso pero no molesto y el diseño es muy elegante. Y lo que más me agradó es el anillo interno para afinar los distintos niveles de molienda para algo más exacto y personalizado.

Love the looks and the quality grinding it offers. The only negative thing is the time it needs to grind the x amount of beans. I tried from dark to light roast beans without any problems until now.
