Does anyone have recommendations for affordable whole bean coffee for the Aiden that can be found at the supermarket?

Hi everyone  the product team wanted to give a heads up about some final validation work we’re doing on Aiden related to an upcoming firmware update.

Starting yesterday, we began a slow rollout of firmware version 1.5.9 to around 300 devices and are closely monitoring their performance and feedback. Some of you have already been helping us beta test this version, thanks for your help so far! If you happen to be part of this initial 300 rollout group, feel free to drop feedback in this thread as you use the machine. 

Here are the main changes included in this release:

• Connectivity improvements: This release includes a number of under the hood connectivity and reliability improvements. 
• Timeskip fix: Previously, the machine could occasionally jump forward by around a minute during brewing. You should now see much more accurate brew countdown behavior with little to no “timeskip” during the brew cycle.
• Brew timing accuracy improvements: In previous firmware versions, the timing of individual infusion stages could sometimes be slightly inaccurate. We’ve improved stage timing accuracy in this release. This may slightly affect how some profiles come out. We wanted to give everyone a heads up in case some profiles need minor dialing in afterward.
• Descale timeout fix: We’ve updated the descale flow so completion is properly recognized after stage 3, and the process should no longer time out as aggressively during descaling.
• Showerhead UX removal: In older firmware, Aiden would show an error if the configured showerhead setting did not match the brew basket size. We are removing the showerhead-specific logic. We do not expect this to meaningfully impact the brewing experience, but wanted to call it out in case users notice the change. Basket size warnings related to brew settings in the UI will continue to function as normal.

Timeline:

The plan is to continue rolling out after this initial validation period of 1-2 weeks. If your Aiden is connected and online, you'll get the update automatically!

Our goal with this release was to address some of the larger UX issues we’ve seen while continuing to improve overall stability and consistency both in brewing performance and WiFi-connected functionality. We’ve got more improvements planned down the road, but getting the platform solid and reliable has to come first. 

As always, we appreciate the feedback and support from everyone using Aiden day to day.

Happy brewing!

A day after I ordered a new Aiden showerhead (white because black is out of stock-too late to cancel says Fellow AI chat, even though it still hasn’t shipped), Fellow announced a new upcoming firmware upgrade, 1.5.9. https://www.reddit.com/r/FellowProducts/comments/1t7crg5/upcoming_aiden_firmware_update_version_159/

"In older firmware, Aiden would show an error if the configured showerhead setting did not match the brew basket size. We are removing the showerhead-specific logic. We do not expect this to meaningfully impact the brewing experience, but wanted to call it out in case users notice the change. Basket size warnings related to brew settings in the UI will continue to function as normal".

The problem is corrosion of a small metal part in the showerhead control switch, which sets the single or batch water dispersion pattern. The tiny part itself (not sold separately) quarter screws into the middle of the showerhead. It is a well known, documented issue, and Fellow has replaced entire units under warranty because of it.

Fellow solved "their" problem (warranty replacements), but users lost a feature (admittedly, not life altering). I just wanted to save one more button press to override the software warning when brewing an "Instant brew”, which I will be able to do once the new firmware drops.

What I'd like opinions on; was this the proper course to take? It reminds me of the old joke: "Doctor, it hurts when I do this!" "Then don't do that!"

Opinions please. Fix the problem, or remove the feature? Engineer opinions welcome. Fellow looks, to me, selfish and greedy, not customer focused. The part, redone and water sealed (or just sold separately for a few dollars, or hey, even given away free), was the proper resolution imo. Doing away with the feature was the cheap, dirty, quick fix.

I'm new to the espresso game and received my ES1 in malted chocolate and maple pre-order back on March 5th, but I haven't opened it yet since I'm waiting to buy the matching Opus 2 grinder. I was told that it would be available to order in May, but I'm getting anxious sitting on this machine for the past couple months.

Does anyone have an expected date when the Opus 2 in malted chocolate and maple will be available to order?

Yeah, it’s plastic.
Yeah, it’s louder than the Opus 1.
Sorry Nick… but first grind? ~0.3g retention.
Did it dial in on my ES1 faster than the Opus 1 and the X64SD? Yep.
That big chunky knob — super easy to adjust.
Did it feel cheap or like it was gonna fall apart? Honestly, no.
I’m not some espresso pro — just a beginner on grinder #3 — but I’m pretty stoked on this thing.
Can you nitpick it? Sure.
But for $200… it just works. And it works well.
Also… it’s $200. Some hand grinders cost more than that.
Perspective: this thing is cheaper than the tax on some “endgame” grinders.
Good job, Fellow.

Hey everyone! We’re in the midst of pushing out a new firmware update (v2.3.20) and wanted to give everyone some details on what to expect:

• Shorter priming time (less water, faster start)
• Volume and temperature offsets now apply properly, especially coming out of sleep
• Profiles with more than 6+ infusion stages are now stable and will no longer crash or cause lag
• Improved grouphead rinse consistency
• Fixes to cleaning and descale flows for better stability
• Steam temperatures are now adjusted based on milk type in the “make a drink” flow
• Added protections related to grouphead heat when going to sleep

The team is keeping a close eye on reddit and we'll continue to improve Series 1 over time. As always, let us know how it feels after you’ve updated!

I thought a release like the Opus Gen 2 would have at least a single review somewhere online (apart from the few that have popped up here). The reason I want to see something in depth is I just had a df54 get delivered but I also preordered an Opus Gen 2, and one of the variants that doesn’t ship till a month from now. I’m trying to see if I should a. Cancel my preorder or b. Return my df54 in the 30 day window.

Anyway thanks for the people who have ordered and posted mini reviews here! It helps a lot, I’m just hoping for a more in depth review eventually.

I pre-ordered the ES1 through Coffee Merch in the UK, and it was supposed to launch in the summer, since ordering they've provided very few updates, now I'm seeing that the website is saying "Autumn 2026", does anyone have any more information about this?

Fellow Prismo or Aeropress flow control filter cap? - Fellow recently came to Australia so prismo not yet available at this time

Also, which Fellow drinkware do people own and think it's worth it? I might want to buy new glass cups and bottles

Thanks

Got an Aiden for my birthday in March. Regular disconnects from WiFi despite being close to the router. Customer service was escalating. Never heard back. If you let your coffee sit in the carafe for more then 30 minutes expect a lukewarm result at best. This is the worst “luxury brand” product we’ve ever bought and its website won’t allow me to add a review. It looks cool, the coffee is good when it’s hot. You have to reset the clock every time you unplug it to troubleshoot. The WiFi issue for me has essentially kept the reason that I bought it as unreliable at best. Worst customer service I’ve experienced. No response in nearly a month after they were escalating my issue.

Hey everyone, I’m hoping some experienced espresso folks can help me figure out whether this is user error, my grinder, the machine, the beans, or some combination of everything.

I’m new-ish to dialing in espresso, but I’ve now pulled around 40 shots and I’m completely stuck. Almost everything I make is extremely sour, sometimes sour with a bitter/harsh aftertaste. I’m still within my return window for the equipment, so I’m trying to figure out whether I should keep troubleshooting or return/exchange something and go with a different setup.

Equipment

Espresso machine: Fellow Espresso Series 1
Grinder: Fellow Opus Gen 2
Current beans: Bodhi Zen from Bodhi Leaf
Bean notes: chocolate, raspberry jam, honey
Roast: medium, listed as 3/5 darkness
Freshness: beans are fresh from this week

Prep / accessories

I originally started using an IMS Competition Convex 20g basket because I thought it would help, but I’ve since switched back to the stock Fellow basket to simplify troubleshooting. I’ve also been using an IMS Big Bang puck screen, WDT tool, level/firm tamp, 18g dose, and a scale under the cup.

Fellow Series 1 profiles I’ve tried

Medium profile

• 18g dose
• 1:2 ratio
• 92°C
• 5 sec pre-infusion at 3 bar
• 25 sec infusion at 9 bar

Light profile

• 18g dose
• 1:2.5 ratio
• 94°C
• 5 sec pre-infusion at 3 bar
• 20 sec infusion at 9 bar
• 5 sec ramp down

Classic 9 Bar profile

• 18g dose
• 1:2 ratio
• 93°C
• No real pre-infusion
• 28 sec infusion at 9 bar

Volumetric offset changes

The Fellow Series 1 was originally stopping shots way short, often around 19–24g out, even when using an 18g dose.

I contacted Fellow support and they suggested adding 20ml to each volumetric offset:

• 1st Offset: 48ml → 68ml
• 2nd Offset: 44ml → 64ml
• Nth Offset: 44ml → 64ml

After doing this, the machine started producing more normal output amounts, but the shots were still extremely sour.

For my latest attempt, I dialed the volumetric offsets back slightly to:

• 1st Offset: 63ml
• 2nd Offset: 59ml
• Nth Offset: 59ml

Shot results / timeline

Here are some of the notable shots I’ve tried.

IMS basket + puck screen, Medium profile

Grind 1.0
Output: about 25g
Time: about 21 sec
Taste: slightly sour, but this was one of the more promising shots early on

Grind 1.1
Output: about 20.4g
Time: about 18 sec
Taste: very sour
This confused me because going coarser gave less output and a shorter shot.

Grind 0.8
Output: 19.3g
Time: 26 sec total, 5 sec pre-infusion + 21 sec infusion
Taste: extremely sour

Grind 1.0 again
Output: 20.4g
Time: 19 sec total, 5 sec pre-infusion + 14 sec infusion
Taste: extremely sour with very bitter aftertaste

At this point, the machine seemed to be stopping way too early.

Manual stop test

I manually stopped a shot at 36g out to test whether the machine was just ending the shot too early.

Grind 1.0
Output: 36g
Taste: still very sour

So the issue does not seem to be only the machine stopping at 20g.

Light profile tests before offset change

Grind 0.8, Light profile
Output: about 31g
Time: around 22–25 sec
Taste: still way too sour

Then the machine suggested grinding finer.

Grind 0.4, Light profile
Output: about 24g
Time: around 18–19 sec
Taste: still way too sour

This was confusing because grinding finer seemed to make the shot shorter and produce less espresso.

Grind 0.0
Result: basically choked the machine
No water/espresso made it out
Clearly too fine

After Fellow’s volumetric offset changes

After changing the offsets to 68 / 64 / 64:

Grind 0.5
Result: slower flow
Output: about 40g
Machine suggested going coarser
Taste: still very sour

Grind 0.8
Output: about 36g
Time: 44 sec
Taste: still super sour
Machine suggested going coarser

This was also confusing because I expected 0.8 to flow faster than 0.5, but it took 44 seconds and was still sour.

Stock basket tests

To simplify things, I switched back to the stock basket.

Stock basket
18g dose
Grind 1.0
WDT
Tamp
IMS Big Bang puck screen
Medium profile
Output: about 41g
Time: about 26 sec
Taste: extremely and unbearably sour

Then I tried the Light profile because it runs hotter at 94°C.

Stock basket
18g dose
Grind 1.0
WDT
Tamp
IMS Big Bang puck screen
Light profile
Output: almost 44g
Time: about 26 sec
Taste: still very, very sour

For the latest attempt, I dialed back the volumetric offsets to:

• 1st Offset: 63ml
• 2nd Offset: 59ml
• Nth Offset: 59ml

Then I tried:

Stock basket
18g dose
Grind 1.0
Light profile
Output: about 44g
Time: about 26 sec
Taste: still very sour

Where I’m stuck

At this point, I don’t know what the main problem is.

Some things point toward needing a finer grind because the shots are sour and the beans are a fresh medium roast. But other things point away from going finer: 0.0 completely choked the system, 0.4 produced less output and still tasted sour, 0.8 after offset changes took 44 seconds and was still sour, and the machine started suggesting going coarser.

With the stock basket, 1.0 grind, and Light profile, I got about 44g out in around 26 seconds, which seems like it should be at least somewhat drinkable, but it was still extremely sour.

I’m honestly pretty frustrated because I’ve tried around 40 shots and feel like the grind changes are not leading to clear improvements. I’m not expecting perfect café-quality espresso right away, but I’m surprised I can’t get even one balanced, drinkable shot.

I’d really appreciate open feedback on what you would do next. I’m trying to figure out if this sounds like a grinder issue, a machine issue, a coffee/bean issue, a puck prep issue, or if I should return anything while I’m still inside the return window and move to a more beginner-friendly setup.

Can the Fellow app be updated to allow a custom time set for schedule notifiacations. Right now I get notified 12 hours before but I would really like to be reminded at 9 PM instead.

After 3 grinders, countless bags of big island’s best coffee, turning off volumetric dosing all the while doing disaster relief work I finally for a newbie have got consistent shots 36 grams between 25 and 30 seconds. All that to realize straight espresso taste like doodoo lol. I love a flat white and cortado but espresso by itself is no bueno. But I am on a quest, how do I get the old school Italian espresso, I want to know what the people who invented it liked. Recipes, roast levels maybe even bean recommendations.
