The static is a nightmare. I have a white version and the coffee is everywhere. Retention also is a joke. Apart of that, it is a OK grinder. Definatelly will look for something better next time.

Ive drank crap coffee for 30 years and now overnight im looking to spend hundreds / thousands to make better coffee at home lol. So i decided to not go completely insane right away and ordered the opus. Do i even love coffee? I dunno!

Great video! What setting do you suggest for light roast (e.g. gesha) for filter coffee? Tried 6 but too much fine grinds

Just got my Opus. I’m probably THE target group for this grinder as I’m into coffee, but also a mere mortal. Not a barista, not a die hard enthusiast. I lived with a $90 Wilfa WSCG2 for years, but got a cheapo espresso machine for fun. ”all purpose” really is THE selling point, price next. I just can’t excuse a purchase of much more than $200. And I got to say. Damn this grinder is something else. The build quality, the quiet operation, the button feel, the grind quality, the tolerances, magnetic and well designed catch cup. This grinder is awesome. The fact that this is just about 2-2.5x the price of my previous just boggles my mind. Great job fellow!

I bought opus in November 2023 and experience the huge retention, so naturally I always knock the machine to get the ground coffee out. Maybe one time I knocked too hard and suddenly (February 2024) I see the burr is somewhat wobbly and the grind time increased 2-3x times longer. I took it to the shop where I buy the opus and they do not have the 'knowledge' to problem / repair the grinder. I have now make peace with the longer grind times, but found it to be more inconsistent than before. When I pull 2 espresso shots with no breaks, the first one seems normal (19 to 40gr in 25 seconds), but the second one is just flowing too fast (19 to 40gr in 20 seconds). That's a huge different and I don't know why. I couldn't find a long term review when I bought this grinder, so yeah, I wish I didn't buy this grinder (for espresso) haha.

Thanks for your experimentations! I enjoy studying coffee science and am trying to discover new ways of making cold brew in big batches for nitrogen infused coffee. Vacuum extraction was my first idea, with a vacuum environment having a low boiling point the extraction could speed up immensely but a vacuum chamber for a five gallon batch seemed like a lot of vapor the pump would have to work on to keep the vacuum going. Cavitation was next with pressure and quickly releasing the pressure but not much more than studying the process. During these experiments in my head oxidation became a primary concern both for taste and keeping everything fresh for extended periods. The thought that won out and now has lots of equipment is using a nitrogen generator to brew coffee in a 6.5 gallon keg under pressure of nitrogen, purging the oxygen from the air and water and the CO2 from the brewing process the keg is also slowly rotated during the brewing process and filtered afterwards then placed into kegs in a kegerator under pressure of nitrogen. I’ve been considering placing ultrasonic transducers (not sure of the frequency yet) onto the brewing keg but still need to master my keg brewing method first. Of course taste is the primary concern and I’m thinking an oxygen free brewing container is a good idea. Thought you’d like to read about my ideas, I’m kinda deep in the rabbit hole 😀

Just bought one myself. What I’m gonna try and you should too is I’m gonna pre rinse my coffee before I vac it. Just for kicks and giggles. See if it will change the flavour, my take away some bitterness? I figure they do that with green tea in china?

ok but the mushroom mug is Adorable ;___;

Question I use this just for filter coffee it jams daily. It makes great coffee, but it drives me insane that I have to bang it to get the coffee out. Any suggestions of how to fix this?

I came from the Ode 1. Tapping comes 2nd nature to me. Lol

Very interesting! I'm looking for an electric grinder for filter coffee, and I'm on the fence between Fellow Opus vs Fellow Ode Gen 1 vs Baratza Encore (not ESP). Thoughts? Other suggestions in same price range? My old grinder is a blade, so any of these would theoretically be an improvement :)

Do centrifuge at lower rpm or use vacuum filtering, heck use the aero press to filter.

I love my Opus, and largely use it for espresso. That being said, I may not be attempting to dial my grind in as perfectly as many more experienced espresso enthusiasts. The price for me, combined with the ease of cleaning and use makes it well worth the purchase.

Sound is ass, but the editing and content is on point 😂

incredibly insightful review thank you! how does the retention on the opus compare to that of the ode? would you say its any better? was literally about to check out on buying the opus rnrn but this video made me reconsider.

I regret buying the opus. Retention is ridiculous and now mine makes a burning (electrical) smell inside. I’m just waiting for it to die to justifying a better grinder

I drink cacao, not coffee. I've been looking for a mug I can throw into my bag to take on my bike. This one looks pretty good.

Thinking out of the box And I like the care of technical details too

Absolutely agree with you! ⭐️⭐️⭐️⭐️⭐️

I sub’d as soon as I saw the chart 👏

I’ve been using my Opus for espresso for the last four months now, and just recently the retention has turned into caking just below the burr. The caking is so bad that tapping on the top will not knock it loose, I have to remove the outer ring and brush it out for every shot. Any suggestions on what I would need to clean to prevent this?

Why does my grinder grind but not grind.. Like it doesn't produce coffee just spins.... Like I've taken top burr out cleaned and all. Still nothibg. Wtf..

LOL why is this so hard for people to understand? If you're at 2 on the outer ring, then adjust the inner ring coarser, you are just 50 microns coarser than 2. You don't go adjusting the outer ring after that..... YOU are making it too complicated.

Thanks!

For someone who has a microphone on the side your audio levels are very weak, can barely hear anything

my issue with this grinder is that whenever I adjust both inner and outer ring, subsequent grounds are more fine that what I originally set, requiring further adjustments, this is insane! and also the grind time has increased about 10 more seconds, now I have to push the button twice rather than just once for 17.5g. I should have not bought this one tbh.

I’m that guy you thought was crazy. You’re not skipping gears or damaging anything. It’s actually why Fellow tells you to do. They have you move to 6, adjust the inner ring and then move back. The 6 is arbitrary. They want to make sure you have room to adjust (don’t go past 0) and they want to make sure you let the adjustment take place (move the outer dial). The key insight (which you get when you watch that step less video) is that the inner ring doesn’t move the burr. It doesn’t adjust the grind. It adjusts the outer ring. Think of it like this. You’ve got a screw thread that when you turn, moves the burr. You’ve got a knob on that that has detents. Say, every quarter turn you have a detent. Now, you have nice steps as you adjust that knob and can return to the same spot. Imagine now that you can rotate the detents by a small amount. Doing so didn’t actually move the screw - just where the detents are on the screw. The detents are rotated say a quarter turn. Rotate the screw now and it’ll land in a different spot as the detent stops it now between previous positions. But, you have to move the screw to make that happen. You’ve adjusted the adjuster not the burr itself. Maybe 1 click will do it but exercising it makes sure it’s settled. The problem is that the overall movement has some flex and lack of precision. Going way out and back and you may not hit that same exact burr location.

You want to use an ultrasonic homogenizer for best results in flavour extraction. kzbin.info?search_query=ultrasonic+homogenizer

I'm interested on the Opus because I want a reasonably quick and quiet single dose grinder for immersion brewing at the office. It sounds like it might still be a good choice for me -- do you have any other recommendations? Thanks!

GOOD VIDEO

Nice idea, a fun idea would be getting an ok coffee and seeing if hint water makes it better.

the inner ring is super confusing, I tried for a while to figure it out for espresso but eventually gave up and just use it for our daily filter coffee. also the need to keep hitting it to deal with retention is loud and frustrating.

8:50 that was clean as hell! Now back to the video lol😝

hi i drink mostly moka,,,i havce a baratxa but his time is ending burr really bad this days,,,wouls like bigger diametter gringer any suggestion df64 little prycy but i think at least will last loner , bartazxa lasted ok like a 1.5 year thanks

100% about the static!

Hey, I've owned a Fellow Opus for around three months now. To make the grinding process cleaner I was considering starting to use RDT, but I was scared it might break the machine. How long have you owned your Opus? You said you used RDT, and I'd just like to know over what period of time you used it

Hi S,Are you selling your slings? I actually don't know why I would need one other than I go to a lot of Doctor appointments. I'm not active because I'm super ill for 20 years. But as I said I do goBut as I said I do go To Doctor appointments a lot. But of course I'd rather be rock climbing like you 😂

I have been using Opus for about three months now and I have to say I agree with almost every point you made in the review. The retention is pretty bad if you don't tap, but the straight-down arrangment of the grinder helps to keep the retention minimal once you do tap. The V60s from Opus have been great, the espressos (using the Flair) are hit or miss, but I'd say it's rather a workflow issue on my part. Out of the box it was grinding way too fine for me, but after readjusting the dial I'm pretty happy with it.

Ooo this looks so good! How much vanilla would you add into the recipe (if you wanted)? Or is that just to taste?

during your quit cuts making the coffee the audio is a lot louder than the other video, try to make the audio levels the same throughout the video.

Nice review. I bought the Opus a while ago. When I took it out of the box the default settings applied, e.g. that number two was actually the espresso range and so forth. Then I made the mistake of doing those microadjustments after which number 3 is now what number 2 used to be., and number 2 and everything between 2 and 3 is just powder that'll choke my espresso machine. There's literally no instruction on how to reset the machine (apart from some tutorial where you first have to tear it to pieces, which I'm not going to do). Fellow's opus intruction videos don't really work or tell anything about how to reset it. And frankly a grinder isn't supposed to work like this. If you can't adjust and readjust without losing your mind and not knowing where you are on the grind scale, it's pretty bad. Yes, it does grind fine enough for espresso. Can I recommend it? Definitely not.

I use a chamber vac to infuse fruit juice into apples (or other porous fruits and cookies). I take frozen blueberries or strawberries, smash them into juice, and then infuse with a chamber vac into other fruit or cookies. Super sweet and no sugar needed, a very different dessert, you pick the fruits.

Who doesn't love the Wegmans water isle

Thank you for the review! As someone with an Opus, it's nice to hear other thoughts on it. I own it in white and haven't noticed any of the wear that seems to plague the black units. The white also hides any fingerprints or smudging (but coffee turns it brown haha so thats something to keep up with). Your comment about some people finding the grinder to be set more coarse or more fine from the factory than intended is very interesting as I always thought I was grinding WAY higher into the numbers than others for filter coffee. So maybe mine is just a bit more fine! Love the filter coffee on this and also was easy to dial in for moka pot! Haven't made it down the espresso rabbit hole yet, so curious to see my thoughts there.

Bro that's the termite don't put your head near it

Just wanted to say thank you for the kind words and thank you for the review. Totally get your feedback! Also, I wanted to just mention quickly that we at Fellow had 4 engineers working tirelessly on this thing (Andrew, Matt, and Pat plus myself), plus all of the people who did marketing / planning / logistics, etc.! I just wanted you to know the names of everyone else who worked to get this out. We're always looking to make things better. :)

I have an opus for about a month. Its my first electric grinder and i say for the bucks it does the job pretty good. Retention is pretty damn but i learned that if u keep 1 bean and grind that single bean after you grind the others then plunge it(using the lid), itll come out good (most of it i guess).

I don't know if it's inherently like that or if it's a flaw. The magnet on the base of my OPUS is loose. It follows the cup every time I take it out, making a gurgling sound. Only used for less than a month, quite annoying. I use another way to avoid scratches on the base, using mouse feet, it looks quite good and is a bit more slippery.

so annoying that none of the timemore scales come with a case, would give way more peace of mind when travelling, I'd even pay more for it :(
