Fellow Opus Conical Burr Coffee Grinder – Electric Espresso Grinder for Home Use, 41 Adjustable Settings for Drip, French Press, Cold Brew & More, 40mm Stainless Steel Burrs, Matte Black

The function is so simple there's not a whole lot to say about it, but I like the grinder. I have a new Fellows coffee maker on order, but in the meantime, I'm using it with my current coffee maker. I was using a Krups blade grinder with a momentary "on" button, but this Opus grinder now makes it clear to me that a blade grinder like the Krups will never produce consistent results--at least I never was able to achieve consistent results. I immediately started getting better results with the Opus. Because I really have no control on my current coffee maker over parameters that affect extraction, at least I now can set the grind level to optimize extraction results for that coffee maker. So, I really believe that this grinder will enable you to achieve better results even with simple coffee makers. I would also recommend that you get a digital kitchen scale to measure your beans. I scooped out beans for a batch using my typical method and got a feel for how many grams I use for a batch. That's another parameter that's worth controlling. Small changes in amount can be noticeable especially in small batches. Obviously you want to carefully measure you water as well. Reviews regarding retention are mixed. I don't see a problem in that area, but I do need to tap on the grinder to clear it out. When the grinder is finished grinding but still running, I just tap lightly on the top and sides with my knuckles to knock loose retained grounds, and then stop the grinder and empty the bin. I then start the grinder again and repeat the tapping process. There probably will be some more coffee grounds in the bin. I typically need to iterate a couple of times until no more grounds come out. A bellows product is available, but my experience is that tapping and the bellows produce the same results. I recognize that operating this grinder is a little simpler than piloting a 747, but the manual is a bit weak. When I initially opened the package, the catch bin had the espresso attachment in it. It had me scratching my head for a minute, and the pictorial in the manual of the various parts did not show it. Of course I eventually figured it out, but I don't know why the tech writers would skip that detail in the pictorial. And, as has been documented in reviews, the internal grind level control is not documented. Kinda slack in my opinion. Overall, I expect this Opus grinder to work out great.

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.

I've used the same Baratza Virtuoso grinder for over a decade. Hundreds of pounds of coffee have been ground with very little issues and all were very easy to fix because it's designed to be serviceable. It has its shortcomings, grind consistency being one of them, but you can work around it, especially since it generally will allow some coffee through that's slightly larger then desired. Not a dealbreaker. But when it started getting loud I knew it needed some parts replaced but I decided to "upgrade" my grinder instead. Here's where the Opus comes in. Researching options I kept reading that the more expensive Fellow Ode grinder was very prone to clogging and unclogging things was a lot of work. Many said it happened every couple weeks. Oddly I wasn't seeing as many complaining about the Opus so I opted for this. When first setup it seemed to be a great looking grinder but that was short lived. I measured out 50g of medium roast beans for a partial pot of electric coffee maker coffee, set the grinder to 8 which is in the middle of where they recommend per the inside of the grinder lid (props to them for the neat chart), and told it to grind. . . Grinder turned on but the beans weren't feeding down to the burrs. . . Once I helped them along it started to grind. When I removed the catch bin it was immediately obvious the coffee was ground too fine. I tried brewing it anyways and the basket ran over, leaving grounds in the coffee. Let's try this again. I pulled the lid off the top of the grinder and the bean load bin had chafe all over in it. The top lid creates an air tight(ish) seal when you slide it on so upon removal it pulled the lightweight chafe into the bin. Cleaned it out, poured beans in, adjusted the grind to 9 which is the coarsest they recommend for my coffee method, and put the lid back on. But now the air tight lid forced trapped coffee grounds out the bottom of the grinder, all over the place. . . Right in their description they say "mess-free mornings" and "anti-static technology" yet I'm not seeing either here. Cleaned things up and ground the coffee beans and immediately noticed there barely a difference in the grind, still being much too fine. Tried again with a grind setting of 10, and again at 11. Even at 11 (the coarsest it goes) the grind was too fine for the brew method even though this is the setting for cold brew, what should be a very coarse grind. And I didn't give up here. I proceeded to use the grinder for a week, trying to figure out what's going on, and as time went by I couldn't get a good grind but did notice the grind time was getting longer and longer, and it seemed as though the grind was getting finer. . . It was clogging, just like Ode reviews complained about. It was taking 4 minutes to grind 50g of medium roast beans- I can hand grind faster than that. We're done with this grinder. Before boxing it back up I ran a little test for others to see what I'm dealing with. In the pictures the left dish is a grind setting of 5, the middle is 7.5, and the right is 10. Very little difference, especially considering 5 is the middle grind setting but was so fine that it's espresso fineness, and 10 is the coarse cold brew setting. All that being said, avoid this grinder. Other reviewers give it praise but that's not what we saw. The Encore that replaced this (for less money) worked right out of the box, with the grinder set to the recommended setting and we finally had a good pot of electric brewer coffee.

I honestly debated buying the Fellow Opus for weeks, but I finally pulled the trigger, and I'm genuinely obsessed. For years, I struggled with trying to make one grinder do everything—it was always a messy compromise between my morning espresso ritual and the big French Press batch I make on weekends. The Opus has completely solved that problem. The 41 grind settings are the absolute hero here. I can now effortlessly jump from a super-fine, consistent grind for my espresso machine (seriously, the consistency is top-notch, leading to perfect pulls) to a perfectly uniform, coarse grind for my French Press or Cold Brew. The clean taste and absence of "fines" in my brews is a night and day difference. I'm finally tasting the nuanced notes in my beans that I was missing before. Beyond its performance as a true workhorse, this thing is a beauty. The Matte Black design is sleek, compact, and looks incredibly sharp sitting on my counter—it instantly elevated the look of my whole coffee bar. It's quiet enough not to wake up the whole house, and the dose cup system makes my morning routine so much cleaner. If you're a home brewer who demands quality across all brew methods, trust me, this is the one. It's the best coffee upgrade I've made all year.

The Fellow Opus is a solid choice for anyone getting into espresso or pour-over brewing. It made a noticeable improvement in my espresso quality right away—much more consistent and flavorful shots compared to my previous grinder. It looks great on the counter, has a quiet grind, and I love the magnetic catch can—it clicks into place easily and keeps things tidy. However, there are a few drawbacks. Grind retention is definitely an issue; it tends to hold onto grounds and can get clogged, especially with finer espresso settings. The build is mostly plastic, which doesn’t feel quite as premium as it looks. That said, for the price and performance, it’s a strong entry-level grinder. Just be prepared to give it a little maintenance and regular cleaning to keep it running smoothly.

The grinder functions well enough given its price point and design. You're getting a decent grind and I don't have huge complaints with the coffee that this grinder makes. My biggest gripe with the grinder is its retention—there's an unacceptable amount of retention, often exceeding 1g. The retention becomes slightly less noticeable (but still unacceptably high—think >0.5g) once you run a couple of rounds of beans into it, but there's a lot of old, stale coffee being held in the grinder that will impact your next cup. Those old grounds get expelled when you grind another batch of beans, and the new batch is what ends up being retained. Not good. A workaround that I've found is knocking the grinder around and tilting it side to side while doing so. That'll usually expel a decent amount of grounds, but you're probably not doing any favors for the longevity of the grinder. Another thing that helps is constant cleaning—about every other day, I'll remove the outer burr and use a brush to knock down the old grounds. Retention tends to be extra bad for the first cycle afterwards that I run the machine, but at least the old coffee gets expelled. You could also try RDT (spraying the beans with a spritz of water before loading them into the machine) to reduce retention and static, but I've yet to try that. The anti-static mechanism doesn't really work in my experience, and there's always a huge amount of grounds stuck around the exit chute. When you remove the catch up, sometimes those grounds will fall down (or there will be retained grounds that fall), which is a pain to clean up. As a starter grinder, it's passable, but you'll probably want to upgrade if you're seeking a product that is less messy and doesn't require almost-daily attention. Especially for people who are "getting into coffee," this probably isn't the right equipment to start with. For the money, you're better off buying a manual grinder at the same price point. For folks who aren't precious about their workflow when making a cup of coffee and don't mind pain points, this is a fine machine and it'll at least make your kitchen counter look a little nicer.

Over the years, I've had over a dozen different grinders and I can say this is the best one I've found. It's the quietest grinder I've had and the grind is very consistent. The best feature is the ionizing static removal. Even in the low humidity of the winter, the coffee grounds are not statically charged at all. The only drawback I've found is that with oily dark roasts, the beans tend to stick to the hopper and not fall into the grinder. You have to push them around a bit to help them drop. A nice feature (not mentioned and maybe unintended) is that the hopper lid fits snugly and can be lifted and dropped a couple of times after the grind finishes to force the remaining grounds through the channel and into the cup. This tends to keep the blades cleaner. I've had good luck with all of the fellow products. The pro water kettle is amazing also.

The Fellow Opus is a class-leading grinder, perfectly blending excellent performance with brilliant, mess-free design. It is the essential upgrade for any serious home brewer. Key Features & What I Love: Magnetic Catch Cup: The best feature. The cup snaps securely into the base, eliminating grounds spillage and saving cleanup time. Magnetic Lid Guide: The single-dose lid is also magnetic, keeping dosing neat and preventing rattle. Initial Consistency: Excellent consistency across 40+ settings for all brew methods, from pour-over to espresso. Minimal Static: Anti-static technology works effectively for a cleaner experience. Sleek Design: Looks high-end and compact on the counter. The Trade-Offs (What to Know Before You Buy): Single-Dose Focus: Best suited for 1-2 person households. Long-Term Consistency Drift: While excellent initially, consistency can drift slightly on finer settings after heavy use. Expect to re-dial occasionally. Overall: The Opus shines thanks to the ingenious magnetic catch cup, which makes the daily ritual neat and satisfying. While the grind consistency may need minor re-dialing over long-term use (a common trade-off in this category), the initial quality is excellent and superior to cheaper mills. An easy recommendation for a huge quality-of-life 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.

I’ve been using this grinder every morning and honestly, I love it. It looks super sleek on my counter and doesn’t take up a lot of space. The grind settings are really easy to adjust, and it works well whether I’m making espresso or French press. The grind is consistent, it’s not super loud, and it feels really solid and well-made. Cleaning it isn’t a hassle either, which I appreciate before coffee kicks in. 😅 If you’re into coffee and want something that looks good and performs well, this is a great pick.

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.
