Fellow Opus Conical Burr Coffee Grinder, 41 Settings, Anti-Static, Black

We got the Opus grinder after we spotted it at a local Crate and Barrel. It went well with the design aesthetic of the coffee maker (Aiden) and the grounds were quite consistent at the store. We knew the performance aspect was going to be key. Since both of us approach coffee with wildly different standards (my professional habit versus his deeply technical standards), we approached the grinder with some well-deserved skepticism (with gadgety things). This thing’s performance is very impressive. For my husband, who’s an engineer, the mechanical details were the focus. It’s the consistency, the anti-static process, and the adjustable variables. Systems that provide control, that’s what matters. The ability to dial in grind parameters so accurately for anything (espresso extraction vs a coarse French press) is fantastic! We have an espresso maker, so the espresso grinds were key. The fact that it generates consistent grinds without clumping speaks to a well-engineered design. The attention to utility, like the removable dosing cup, magnetic centering, and the clean system, is well built. I, on the other hand, am a school teacher. My primary need is reliable function and easy routine. The most helpful feature is how quiet and low-mess the process is. Knowing that I can rely on a consistent grind quality every morning is great! It feels like another thing in the morning that elevates the entire morning experience. We both love that it gives us such great quality coffee across every brew setting, and it does so with an impressive degree of unmessiness. Of course, it’s a bit of a learning curve, and it needs attention (who/what doesn’t?!) but it’s a great grinder. Love the thing!

For some context, I like to brew coffee in multiple ways (espresso, pour-over, french press, etc) and do not want multiple grinders. I also did not want to pay anything more than about $250 for a grinder from a reputable brand. Prior to the Fellow I had a standard Baratza Encore (non-ESP) which was basically impossible to get a good grind for espresso on. Other issues I had with the baratza were its chute where grinds would come out, it would just constantly get clogged and oily which made it quite a high maintenance device. So now we arrive at the Fellow Opus. I had a hard time deciding between this and the Baratza Encore ESP, and now Baratza offers the ESP Pro which is a good competitor. I tried an ESP for a week, but the main thing that made me switch from Baratza was that the ESP uses the same chute design as the non-ESP and I hated how clogged and blocky my espresso came out on both machines. Pros: -The anti-static tech works wonders for me. With my Baratza, I would have to do a lot of WDT puck prep because all the espresso came out in blocks. I have had virtually 0 clumps in my espresso grinds on this machine. (pro-tip, you should still clean the contact points every few weeks to keep the anti-static tech working as intended) -Its pretty quiet for a grinder which I was actually really happy about since the Baratza is like a banshee in the morning by comparison. -The hopper cover is a great large dose cup for my drip coffee grinds, and it doubles as a bellows decently enough. -The grind cup and the espresso grinds insert are great, I never have a mess after grinding except for a few sprinkles. I have yet to come across any grinder at this price range that doesn't make at least a bit of a mess after grinding. -The Beanie App is your best friend for adjusting grind sizes using the inner ring! Micro-adjustments with the inner ring are not that hard, many reviews blast this mechanism WAAAAAY to much for the price of this machine. Yes, its not the most intuitive system, but its a single dose hopper. Once you realize your grind is too coarse/fine, its already empty and is easy to take off to adjust. Using Beanie and the same beans makes this easier because it means less adjusting once you find your grind size. -SOOOOO easy to clean, the baratza by comparison was a huge PITA to clean and it would just gather grinds in every darn corner of the chute. -Looks pretty nice for a grinder at this price point. Yes, its plastic and not metal, its an entry-level grinder.... -I find the grind timer button intuitive and simple. I like to do other coffee prep tasks while my stuff grinds, so having everything on a timer is nice. I never have to manually shut off the grinder. Recommend one press for espresso and two for pour-over/french press Cons: -The bottom plate where the dosing cup does scratch easily. I don't think its a huge deal as it mostly gathers really small scratches and even so, it wouldn't be hard to put some felt down if I cared more. Keep it clean of excess grounds and you'll be fine. -The hopper does sometimes catch a few beans. This happened in my Baratza as well, so no big deal to just run the grinder again for 5s to get the last few bits. -Inner adjustment ring is still not the most intuitive design, its NOT nearly as bad as I see so many reviews say for the reasons I put in my Pros section. (Use the Beanie app, it helps so much) -I have to knock the hopper 2-3 times with my hand to get any sticky grounds out. Not a big deal since I have had to do this with my Baratza even more cause of its chute design. Summary: I really love this grinder and think its a perfect entry-level grinder that can basically grind anything decently. Its a jack of all trades, master of none in particular. Especially when its on sale for around $150, I don't think there's as good a versatile grinder with this fine of an adjustment system on the market, including Baratza for all of its clogging issues.

Initially, the grinder performed flawlessly, without any complaints. However, after two months, I began to notice an increasing amount of coffee grind retention in the grinder itself. This necessitated regular cleaning twice a week, eventually requiring manual burr removal to access the unit and clear it out. Despite my daily coffee usage of approximately 36 grams and twice-weekly cleaning, the grind retention frequency escalated over time. As mentioned in other reviews, I found myself needing to perform a full cleaning every two or three days to minimize the retention within the grinder. Unfortunately, the anti-static function was rendered ineffective even after consistent cleaning. This is frustrating, especially since I measure my coffee weight to target 36 grams, and the retention necessitates “guessing” the amount trapped in the grinder. Consequently, I find myself grinding multiple times to achieve the desired weight, making it a guessing game. Given the price point, I would expect better performance. The second issue is inconsistent grind levels that occur sporadically. Despite numerous attempts to recalibrate the unit according to the company’s instructional video, these inconsistencies persist. I have contacted the company, but their response has been slow. When they do respond, their solution involves sending them a video of the buildup in the grinder and a video of the inconsistent grinds. They also refer me to instructional videos on cleaning and recalibration, which I have already performed multiple times. Therefore, I would not recommend the grinder or this company to potential buyers. There are significantly better alternatives available.

We've bought several coffee grinders over the years. All of them sent coffee grounds flying all around the kitchen, it seemed. A constant frustration and mess. I stopped using all of them for this reason alone. For a while we used ground coffee, but I really like beans instead. So I started searching again. I was considering the Baratza Encore grinder, but a few reviewers said it made a mess. Then I stumbled onto Fellow Opus. Wow. This is the grinder I've been longing for! Definitely one of the best things I've ever bought from Amazon. The capacity is enough for 12 cups of coffee, and it seems very durable. Aside from the fact that the grinder itself works extremely well and looks beautiful, it has lots of great features: 1. I like the weight of it, for one thing. Our last grinder was super light, so when I saw that the Opus weighed just under 4 lbs, I was afraid it wouldn't be heavy enough. But it really is! It feels nice and heavy and solid. It stays right in place when grinding. 2. Easily Adjustable Wide Range Settings. From fine espresso grind to pour over and all the way up. All you do is move the little sliding lever or whatever it is, at the top, to your desired setting. Settings are printed on the underside of the lid, also. 3. Lid doubles as a dosing cup. I've used this only once, but definitely will again. It's a handy and thoughtful design. 4. Magnetic Catch Cup. I love this little cup! It has a removable ring or lid with hole in it; I guess it helps keep the coffee grounds from flying around. When you put the cup back in place, the magnet sort of grabs it and puts it in place. 5. I mentioned this earlier, but the grinder itself works like a dream. It has a little button you push to start it. One quick push for 30 seconds, 2 quick pushes for 60 seconds, and so on. Easy peasy. And the noise level is totally acceptable; it runs a lot quieter than our last grinder, or any grinder we've had, really. 6. Absolutely NO COFFEE GROUNDS have flown around or ended up on the counter. Like, none at all. And zero static! I am ecstatic about this grinder. It works flawlessly and I just couldn't be more satisfied with it. I do definitely recommend this awesome product!!

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]".

This grinder looks fantastic at first glance. Very clean, very elegant, and it honestly looks way more expensive than it is. The magnetic dosing cup is genuinely great — I didn’t even know that was a thing until I used it, and it’s probably my favorite part of the whole grinder. Unfortunately, the experience goes downhill pretty quickly once you actually start using it. Retention is the biggest problem The retention on this thing is wild. After using it maybe 5–6 times, I ran it empty, tapped it a bunch, and did a dry run — and almost half a dose came out afterward. That’s not “a little retention,” that’s enough to completely mess with single dosing. You basically need a scale under the dosing cup every time because what comes out is nowhere near what went in. Mess everywhere The grinder has a habit of dumping fine grounds out when you accidentally bump it, which is annoying on its own — but it always seems to happen right when the dosing cup is out, because that’s when you’re putting it back. Those fine grounds end up exactly where the cup sits, so when you put it back in, you’re grinding dust into the surface. Which leads to the next issue… It looks premium but feels cheap The plastic feels like the kind that scratches if you look at it wrong. I only ever wiped it down with clean, super soft microfiber towels, and the only “dirt” on it was coffee dust from the grinder itself — and it still scratched everything from the outside of the grinder to the dosing cup and where it sits. Same story up top. After one grind, the hopper area already has a ton of fine coffee dust. Enough that the really neat gravity-sliding lid won’t go down properly unless you clean it first. And cleaning it just adds more chances to scratch everything. It’ll close if you push it down obviously but that smooth gliding close it has when it’s clean just won’t happen which is a shame because it looks so cool when it does that. Dosing cup: great idea, awkward in practice I love that the dosing cup lip fits a 54mm portafilter perfectly — that part is actually really well thought out. But in practice it creates a huge mound of coffee in the basket. The moment you try to WDT or even touch it with a distributor, grounds spill everywhere. Shaking and tapping the cup upside down doesn’t do anything other than transfer it to the portafilter. Honestly, a dosing funnel would’ve made more sense here, but I appreciate the intent. Grind quality (espresso only) I only used this for espresso. The grind seems reasonably consistent at first, but there are random chunks mixed in, and combined with the retention, shots can be inconsistent. Some slightly under-extracted, some slightly over-extracted — nothing terrible, but nothing impressive either. The coffee isn’t bad, but it mostly just tastes like… coffee. You can barely pull subtle notes out of it. Occasionally it’ll produce a sweeter shot, but it feels random rather than repeatable. Final thoughts There are some genuinely good ideas here — especially the dosing cup and the overall design — but the retention, mess, cheap-feeling materials, and inconsistent workflow completely overshadow them. It works, but it’s frustrating to live with. 2 stars because it nice to look at, but too many real-world issues to recommend for espresso-focused use

We've been using this for almost a couple years now with daily pour-over in our Hario v60 using Cafec filters as we don't have an espresso machine yet. The grind has been quick and consistently sized, doing roughly 25g for our two servings in less than 30 seconds. You can get really granular with the grind size, however we finally landed at a sweet spot for the Hario around 9.5. Since we don't usually bother spraying down the beans which would probably help, there is a lot of static resulting in grounds sticking to several sections. It's never caused any kind of clog though, just a small mess to clean up. The included cup is handy to use for weighing and adding, though at this point we use a Muvna scale with a pour spout instead as it's quicker and more aesthetic, haha. Overall been a great, reliable machine that's easy to use, it processes all the beans added, and you can still hold a conversation while it's running. Hopefully it'll continue to last, but I would absolutely consider Fellow again for a grinder.

I had a basic Krups grinder for several years. It was loud and messy with lots of static in the grounds bin and it would jam frequently with harder beans. So after some research I selected the Fellow Opus Conical Burr grinder. It took some experimenting but I eventually found that a courser setting (10) worked best for my Cuisinart Pure Precision Pour Over Coffee Brewer on the bold setting. I have also discovered that I need less beans (scant 1/2 cup vs 2/3 cup) which will save some money over time. It took some experimenting with settings because my initial tries yielded coffee that was too strong and bitter, but now I am very happy so far. The Fellow Opus grinder is definitely quieter and consistent and there is almost no static in the grounds bin. It is fast and easy to use and compact - looks good on the counter. I would love to buy the Fellow Aiden Precision coffee maker once my current brewer stops working. These products are pricey but so far I am very satisfied with my grinder upgrade.

Le moulin à café Fellow Opus est vraiment impressionnant. Son design moderne et épuré se marie parfaitement avec n'importe quelle cuisine, et il est incroyablement facile à utiliser. Les différents réglages de mouture permettent d'obtenir la granulométrie parfaite, que ce soit pour un espresso serré ou un café filtre léger. Le mécanisme est précis et le broyage est homogène, ce qui améliore vraiment le goût du café. De plus, il est robuste et durable, ce qui en fait un excellent investissement pour tout amateur de café. Je suis ravi de cet achat !

Excelente molino por el precio. Muy bueno para empezar adicional el diseño y la estética es muy bien. Lo único malo hasta ahorita es la retención de café, así que hay que darle unos golpecitos para que salga todo el café. Por ejemplo pones 30g de café y salen aprox 28g-29g, con unos golpecitos basta para sacar el café restante.

nice look and design, but limited functionality. - the machine retains a lot of coffee. need to shake it after each use, otherwise blocked completely after a few weeks. - button function "short press for 30 seconds, 2x short press for 60 seconds... etc) does not work. pressing results in random grinding time of 30s, 60s, or non stop. Useless! - adjustment of grinding coarseness is not ok for espresso. it covers all graduations from fine to very coarse, but the steps are too far apart. we have the very expensive filter coffee grinder and were looking for an espresso "specialist". now we have a super expensive filter coffe grinder and this comparably cheap gringer which also covers mostly filter grade grining, and espresso only very compromised. - for the costs of both machines we should have bought a really professional grinder, and not two chique useless decoration items. very dissatisfied.

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.

Cansado de usar un molinillo manual que, aunque funcional, era inconsistente y tedioso, decidí probar el Fellow Opus, con el que no puedo estar más contento. Es muy fácil de usar: solo tienes que dar con el tamaño de molido idóneo para cada receta de café, y en cuanto lo consigues, obtienes unos cafés dignos de las mejores cafeterías. Cuenta con un ajuste rápido gracias a la corona exterior, con la que se puede llegar a conseguir con bastante precisión el tiempo ideal de extracción de tu cafetera. En mi caso, me resulta algo más complicado porque me gusta utilizar 10 g de café para obtener aproximadamente 30 g de producto y, como uso una canasta pequeña, cualquier variación del molido puede afectar a la cantidad de producto final. Aun así, las aproximaciones con el anillo general de molido son bastante precisas y, cuando se quiere afinar más, el molinillo cuenta con un microajuste interior con el que puedes regular cada paso en 10 micro pasos. El molinillo no es muy rápido, posiblemente tarde más que otros molinillos. Mis 10 g de café los devuelve molidos en 30 segundos, tiempo que aprovecho para ir preparando la taza, el portafiltros, etc. Lo bueno de ese molido a bajas revoluciones es que se consigue un resultado muy homogéneo, con todos los sabores y aromas, y lo más sorprendente, sin estática. Todo el molido cae al vaso de recogida; desde él lo pasas al portafiltros y no se queda nada de polvo en el vaso. Cuando el molinillo no se usa durante un tiempo, entra en modo standby, del que hay que despertarlo con un toque en el botón de molido. Al segundo toque comienza a moler durante 30 segundos, y podemos detenerlo con otro toque. También se pueden dar 2 o 3 toques desde el inicio para que, en vez de moler durante 30 segundos, lo haga durante 60, 90... Yo, en mi caso, siempre le doy un toque; muele durante 30 segundos y, si no noto un cambio importante en el sonido de la molienda, le doy otro toque para que termine, deteniéndolo cuando quiero con otro toquecito. El sonido es bastante contenido en comparación con otros molinillos, y la limpieza es muy sencilla porque genera muy poco polvo y el vaso queda prácticamente limpio al volcar el café en el portafiltros. Estéticamente, queda muy bien en la cocina. El vaso siempre se ajusta en su sitio con imanes, y lo único que hay que tener en cuenta es que, si quitamos el vaso y cae algún granito, puede rallarse la base de plástico al colocarlo nuevamente. Yo tengo bastante cuidado al hacerlo porque he visto reseñas de personas a las que les ha pasado, aunque a mí, de momento, se me mantiene como el primer día.
