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

What more could you ask for in a grinder? Selecting your grind is extremely easy with the large handle and obvious markings, and it gives you a chance to really dial it in perfectly. Little things like the cup snapping gently into place with a magnet go to show how much care went into designing it to be delightful and simple to use. It's beautiful when you look at it up close, and subtle enough to hide in the background of your kitchen. Just a gorgeous appliance. As an added bonus, this might be the most quiet grinder I've ever used. I'm used to grinders being loud enough to wake everyone in the house, but the Opus somehow manages to minimize that noise, and keeps it to a manageable volume. I've paired mine with the Aiden brewer, and I'm absolutely loving the flexibility of both in combination, and really dialing in my process.

I don't make espresso. Never have, probably never will. My coffee world is pour-overs, French press, and now the Fellow Aiden. So when it came time to upgrade my grinder, I didn't need 41 precision settings or the ability to dial in for a perfect ristretto. I needed something simple, clean, and above all, quiet. The Opus delivers on all three. Simplicity That Actually Works The grind settings cover everything I need for drip and manual brewing methods without overthinking it. No endless micro-adjustments, no analysis paralysis. Just straightforward options that produce consistent results. For someone who isn't chasing espresso perfection, this is exactly the right amount of control. The Mess Factor (Or Lack Thereof) My wife has a particular pet peeve: stray coffee grounds on the counter. With our old grinder, it was inevitable. Little escapees everywhere, every single morning. The Opus somehow eliminates this. I don't know if it's the design of the catch cup or some kind of anti-static magic, but the grounds stay where they're supposed to. This alone has made my mornings more peaceful. Stealth Mode Activated Here's the real game-changer: we have an 8-month-old. The last thing I want to do at 6 AM is fire up a grinder that sounds like a jet engine and wake a sleeping baby. The Opus is shockingly quiet. I can grind my morning coffee while my daughter is still asleep, and she stays that way. It's not silent, but it's quiet enough that it doesn't travel through the house. For new parents, this feature alone is worth the price of admission. Bottom Line If you're deep in the espresso rabbit hole, this might not be your grinder. But if you're like me (drip, pour-over, French press) and you value simplicity, cleanliness, and not waking the baby, the Opus is perfect. Our whole house is happier for it.

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.

The Opus has been great. Easy to use, virtually silent, and the grind has been super consistent. I use it mostly for drip and pour over and it’s been spot on. Haven’t had to constantly mess with it or fight it, which is honestly all I want. Feels solid, looks clean, and the magnetic cup is a nice little detail. Pairs perfectly with the Aiden and makes the whole setup feel dialed. Nothing fancy to complain about. It works, it looks good, and my coffee tastes better. LFG!!

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.

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.

I bought this because I wanted to get something that could grind espresso, since I have an espresso machine now. More on that later, but the short version is that if you're using the same type of machine I am then you probably can't make espresso with real espresso grind. I have been using the Fellow Ode Gen 2 for a while, and it's done a pretty good job for my pour over, French press, Aeropress, and the espresso machine. My boss got the Opus though, and I decided to look into it, and on the Fellow website they say this machine is for making espresso, and that the Ode explicitly DOES NOT make espresso. I used my Kruve sifter to check the size of the grind on my Ode at the lowest setting, and... they're right. I looked around, and the general belief is that espresso should be between 200 and 400 microns. A comically low amount of the grinds were in that range from my Ode. So I decided to get a grinder that can handle the espresso grinds, and figured I was happy with the Ode, so I might as well get another Fellow product. Once I received the thing, I set about making espresso with it at the lowest setting, and it... didn't work. It turns out my espresso machine isn't actually able to make espresso if you have the grounds between 200 and 400 microns, but this review isn't about my espresso machine - it's about the Opus! So let's talk about the Opus. The noise level is lower than many of the other grinders I've used. I can't say I'm thrilled with how the push button system works on this. I've become accustomed to the automatic stop that comes from the Ode, so having the burrs keep spinning LONG after the grinding was done is a bit of a disappointment. Does this machine ACTUALLY grind espresso? Yes, and no. Right out of the box it comes with the inner ring at the middle point, and with it at the factory settings on the lowest setting of the outer ring I took 20 grams of grounds and put it through the Kruve and it looks like 10 grams was in the 200-400 micron range (50%) and 9.5 grams was above 400. The remaining .5 grams was below 200. I am going to say that it's very likely that if I were to adjust the inner ring and make it finer there's no question that this machine would be able to get more of the grounds below the 400 mark. I don't want to sit here forever trying to get the exact right setting though, because it takes a lot of effort to sift things in the Kruve (really... a LOOOOONG time). I put about a pound of beans through trying to dial it in for my espresso machine (and that took about 2 hours) only to find out that my machine can't actually use anything finer than what my Ode was able to produce. If I happen to get fired up and want to REALLY dig in on the particle size, I will update this review; but I don't foresee that happening. Pros: - Grinds espresso fine all the way up to French press (or whatever you use that's coarse). Exactly as advertised. - Lightweight. - Reasonably quiet. - You don't need tools to adjust it. Cons: - The grind consistency is lacking. Can't say I'm terribly surprised. I think every grinder I've encountered has had puffed up claims about grind consistency, and they have all fallen quite short. This one is no different than the rest. - Retention. Oh, my gosh... the retention on this thing is INSANE. Watch the video. I don't remember where, but when I first saw this thing (probably last year...?) and as I was perusing around they were mentioning it had "Zero Retention" which I guess was a misnomer. They advertise "Low Retention" now that I look back at their marketing material. I don't know who on their team defined "Low" but that person needs a dictionary. SWEET MOTHER OF MERCY this thing has a lot of retention. If you want to get the grounds out, you CAN get it to where you get out all that you put in. You just gotta smack, shake, jostle, and otherwise abuse the thing to make it give up the grounds. - The build quality is lacking. The magnet in the bottom of the grounds container is really weak, and doesn't do a great job of centering it. Also: the whole thing is made of really cheap feeling plastic that gets scuffed and scratched amazingly fast. The lid on the hopper is covered in scratches. Yes, I used it like a bellows to try and cope with the absurd levels of retention (it doesn't help, by the way. Don't bother trying. You gotta shake it like it owes you money to get the grounds out). It still got scratched up SUPER fast. Like... within the first 3 times I used it the thing looked like it was taken through a war zone. The whole machine is light as could be, and it really tells the tale of how much they decided to skimp on materials and engineering. If you're going to get a grinder, I honestly can't recommend this one. For the price - It's REALLY not that great. I was torn between getting the Baratza Encore ESP and this, and decided since the Ode was really quiet compared to the Baratza Encore I owned previously that I'd go with the Fellow product again. Yes the Encore was louder, but it felt a much higher quality. I might go looking for a bellows for this thing, and I'll probably keep using it for a bit. More than likely I'll go back to the Ode though. I'm pretty disappointed. Maybe someday I'll get a REAL espresso machine that can handle actual espresso grinds, and I'll be able to dust this thing off and let it go to work.

I finally bought the Fellow Opus Conical Burr Coffee Grinder after weeks of debating and got it for Thanksgiving, and I am so glad I did. It solved my struggle of using one grinder for both espresso and French Press, thanks for the grind settings that make switching between fine and coarse very easy. My espresso shots are more consistent, and I am tasting way more clarity and nuance in every cup. The Matte Black design looks sleek and elevates my whole coffee setup, and despite feeling solid and well-built, it’s compact and surprisingly quiet. The dose cup keeps my routine clean, and the grinder is easy to maintain—even when I’m barely awake. If you love coffee and want something versatile, stylish, and high-performing, this grinder is absolutely worth it.
