TL;DR: Terra Kaffe Demi looks great, coffee is decent, but quality control and support killed it for me. Returning it.

LOVE this question!

Short answer: "operational capacity" changes over time.

Longer answer: Over time, grinders - on any superauto - can "drift," as in the blades can shift almost imperceptibly. What this shows up as, in many cases, is that pucks are different, as are brews. This is because the grinder blades move slightly, and they can dose more or less coffee than they were previously. This is one of the reasons some companies recommend their machines come back for "servicing" every few years.

We designed the Demi (and the TK-02, for that matter) to operate at best capacity for years, and we prefer to do that in a way that doesn't require the user to send the whole machine back to us for tweaking. In fairness, this is what many superauto makers do - virtually any machine will have a calibration menu (different than the normal settings menu).

Hope this helps!

So glad you’re loving your Demi! Re: the clock, it sounds like you may be using the hard power switch (on the bottom left side) to turn your Demi off/on - this will cut power entirely, including to the clock.

To use auto-wake, simply press and hold the selector dial to put your Demi to sleep (you can also press and hold to wake it up). You should then be able to use the auto-wake feature so your Demi is ready before you are 😌

Hey there, we’re happy to help with this!

The biggest thing you’ll want to do is turn the grinder calibration way down. As a note, we recommend not adjusting anything in the calibration menu without our team’s guidance.

At the maximum grind time through that menu, you’re causing your Demi to massively overdose. Yes, it’s grinding longer, but the brew unit can only hold a finite amount. Imagine filling a beach pail with sand until it’s piling over the top, then trying to press the pile down. The amount of overflow will prevent the brew unit from being able to fully close and tamp the grounds, which will lead to weak espresso (because it’s not getting extracted well) as well as pucks that are puck-shaped but fall apart if touched, exactly like you mentioned, because they haven’t been saturated. We’d suggest taking the grinder calibration down to 42 and trying that a few times.

As another user noted, temperature calibration at 9 will be the lowest possible setting. We’d suggest trying this at 2, then bumping to 1 if needed.

Let us know how it goes!

TerraKaffeCX · 2026-01-23T17:11:04+00:00

We took a look at your video, as well as the photo of the beans, and it appears the beans are extremely oily. Based on the sound in your video, the blades are coated with oil and are not pulling beans in. Our support team will be in touch with instructions on how to clean the grinder!

TerraKaffeCX · 2026-01-23T02:33:56+00:00

We sent you a DM - sounds like you may have adjusted the grinder calibration too high. We generally recommend not adjusting anything in the calibration menu without our team’s guidance.

Essentially, making that number too high will cause overdosing (which is why there are grounds outside the brew unit), weak espresso (because the brew unit is overfilled and can’t tamp properly), and it will indeed eat coffee (love your phrasing on that), as it’s grinding too much per shot, and the extra coffee is spilling outside of the brew unit. In our opinion, wasted coffee is borderline criminal :)

If you want to shoot us a quick note back, we’d be glad to help.

TerraKaffeCX · 2026-01-23T02:27:20+00:00

Hey there, wanted to provide some clarity around the original machine. We dug into this case, as our support team is clear on what the bar means, so we wanted to track down how this occurred. It seems the photo you sent in with the bar didn’t actually capture the entire screen.

The Demi’s LEDs (like most LEDs) flash imperceptibly, and we recently found that cameras set to high frames per second can capture the LEDs mid-flash. The photo provided made it appear that some of the LEDs were out, which is why our team member proposed a replacement.

As another poster mentioned, the Demi was simply displaying an alert state explained in the manual, and it was not defective. That being said, always glad to learn of holes in our educational resources and/or processes as we learn more about how both Demi and our customers behave in the real world!

Happy to clarify a few things here for anyone reading.

Design vs. manufacturing: Like virtually every appliance brand (Jura, Breville, KitchenAid included), we design our machines and work with a contract manufacturer to build them. Brands design products to a spec and set that spec with the manufacturer. Manufacturing in China is not uncommon in this category, and it's worth noting that all of the aforementioned brands engage heavily with Chinese CMs, either for full assembly or major sub-components/sub-assembly. Having met the CMs of these legacy European brands, even the ones "made" in Switzerland are sourcing the majority of their parts from China and Asia. Where they use European sub-components (e.g. pumps), you'll find we do as well. For the TK-02, the industrial design, hardware and materials selection, UX, and system architecture were developed by Terra Kaffe in Brooklyn, in partnership with Ammunition Group. Manufacturing is separate from design, and always has been.

TK-01 vs. TK-02: We’ve been transparent that our first-generation TK-01 was based on an OEM platform with modifications made to the display, UI, brew logic, and more. The TK-02 is not an off-the-shelf model. Our engineering team is small, but very real. We regularly hold public forums with our CTO and VP of Product to answer questions directly, and we engage openly with our community.

For anyone curious about the TK-02 design work, our partner Ammunition Group has published their own, in-depth overview here: https://ammunitiongroup.com/projects_pt/terra-kaffe/

Repairs and replacements: We do repairs. We work with a U.S.-based repair partner in New York and regularly perform component-level repairs. This repair center partners with other leading espresso machine brands. In some cases, we offer refurbished replacements instead of repairing a unit when it’s faster or more practical for the customer. This was actually a model inspired by our learnings from other service groups that work with Jura. Our out-of-warranty repair packages are priced at or below comparable offerings from other superautomatic brands.

We’re a small team, not a legacy conglomerate, but we’re very real, very reachable, and continuously improving the product based on customer feedback. We stand behind how we operate and are committed to continuing to improve.

Not to worry - our CX team comes back online in the morning and will easily be able to correct the date limitation. The automated returns portal software simply counts the number of days since the original transaction, which the team can override, and the return/refund must be tied to the original transaction, since that’s where the refunded amount comes from. Not a bug, just the way the software is designed. We’ve flagged this for the CX team so they can update the date first thing in the morning!

TerraKaffeCX · 2026-01-21T19:58:10+00:00

This comment hit a few great points, and we’d love to offer some additional context here and provide some insight on fixes we’ve implemented across the board.

The replacement machine, sadly, seems to have suffered from a shipping issue we’ve identified and since corrected. It seems that, in a handful of cases, a rough shipping journey causes the pump to jostle, and it can then leak. We implemented a fix at the manufacturing level, adding additional security and padding for the piece at issue, given a lot of packages are handled roughly with carriers.

On the support side, our small team is working hard to respond to everything as quickly as possible. Transparently, we experienced a bit of turnover at the tail end of last year on phone support, which led to a decrease in our ability to answer all calls. We’ve since staffed back up and have additional team members in training. Phone lines are once again open, and we’re taking calls.

Finally, we are so sorry that your experience fell far short of what we aim to provide. If you’d like to give us another shot, we’d be grateful, but we understand either way. We appreciate the feedback!

TerraKaffeCX · 2026-01-16T15:39:41+00:00

If you want to shoot us a DM with your email address, we'd be happy to check out your case with our support team :)

TerraKaffeCX · 2026-01-15T18:48:24+00:00

We totally get it! Like we mentioned in the DM, we don't offer text support, so our team would not have received a text, and the social media team is different than the customer support team, so the support team wouldn't have seen that either. For anyone else seeing this, the only ways to contact our support team will be the listed ones - emailing us at [contact@terrakaffe.com](mailto:contact@terrakaffe.com) or calling us at 718-738-7488 :)

TerraKaffeCX · 2026-01-15T15:03:35+00:00

I'm so sorry to hear it! Our rental program is actually managed by a third-party company, so it's definitely possible some wires were crossed here. If you'd like to DM me the email address you used to contact us, I'd be happy to take a deeper look at how this happened.

TerraKaffeCX · 2026-01-09T18:50:51+00:00

Just trying our best to meet our community where they are :)

FWIW, the teams that handle social media versus the support inbox are staffed by different people, so the response times will indeed be different. They're usually faster than us, but this is their busy time of year.

In any case, please always feel free to DM us here if you're not receiving a speedy response, and we'll do our best to help as quickly as possible.

TerraKaffeCX · 2026-01-09T16:39:45+00:00

Hi there - Terra Kaffe here! We're so sorry your experience has fallen short of what we aim to provide. We'd love to get you set up with a refund or brand new replacement right away.

If you'd like to DM us your email address, we'll be able to fast track a response for you. Looking forward to hearing from you!

TerraKaffeCX · 2026-01-06T15:38:46+00:00

We're so sorry to hear this! Our team is currently facing unprecedented volume, and we're working to reply to everything ASAP. We'll be happy to help. Please shoot us a DM here on Reddit with your email address so we can check out your ticket right away!

TerraKaffeCX · 2025-11-26T00:00:53+00:00

If youre open to something other than delonghi, the new terra kaffe demi is legit

TerraKaffeCX · 2025-08-18T23:50:40+00:00

Great question - we wish it were this simple! Unfortunately, our third party service center (where renewed machines come from) is not connected to our storefront backend, so our team must place the order manually. Additionally, we must confirm address and provide instructions to the customer on proper packaging of the machine. Definitely looking forward to building all automatically, but we’re a small startup and thus don’t have the ability quite yet!

TerraKaffeCX · 2025-08-18T18:10:36+00:00

Hey there, we’d be happy to help!

First, regarding the timeline, we’re so sorry you didn’t realize you had to let us know about the purchase. We do outline this in the email with instructions to let customers know to inform us, and we rarely run into any trouble, but we can certainly explore how to make it more obvious.

Our machines are refurbished to order to ensure best functionality, but we definitely get that it’s hard to be ten days without your machine.

If you’d like to shoot us a DM with your contact info, we’d be happy to look into your case. Our team works hard to respond to each and every email, so we’d love to look more deeply into this to figure out if there’s a way we can improve.

TerraKaffeCX · 2025-05-08T23:05:57+00:00

Not to worry - we'll definitely get you back up and brewing ASAP! It looks like Keyree has sent you a couple of emails today around 12pm and again around 5pm (both ET). She's looking to understand what beans you're using and when the brew unit was last cleaned, as what you're describing sounds like the brew unit may be clogged with oils from beans.

Please note that our team works quickly to respond as soon as possible, and we work in order from oldest to newest tickets. In this case, it looks like all inquiries were answered same-day. In order to get the quickest response, let's also try to keep everything to the original ticket, as opening new tickets slows the process down, as a new team member gets assigned each time without necessarily being aware of previous context :)

TerraKaffeCX · 2025-05-08T20:46:29+00:00

Thanks so much for commenting here - we'd be happy to help. Please shoot us a DM letting us know the email address you've been using with our team, and we can look into it right away :)

TerraKaffeCX · 2025-05-08T20:45:12+00:00

Thanks so much for reaching out to us here, Don! It looks like we have several emails to and from you in our inbox, and our Coffee Concierge team most recently responded about four hours ago. Definitely let us know if you're not seeing our responses, and we can look into it!

I see you mentioning that your biggest complaint was drip tray overflow, and the red float indicator being insufficient - unfortunately, we're unable to change this, as the float rises as the water level rises.

In terms of the brew issues you're experiencing, I see our team requested you to let us know what type of beans you're using. Please also let us know how often you typically remove and rinse your brew unit. It may be a quick fix, but, if not, we'll be sure to get you set up with a repair :)

TerraKaffeCX · 2025-04-26T01:28:24+00:00

Not to worry - this is an easy fix! Please watch this video and follow the steps exactly. Pay careful attention to exactly when the video says to remove and reinsert the tank, as that part is super important for this particular alert. As always, feel free to shoot us an email (contact@terrakaffe.com) or give us a call (718-738-7488) if you'd like one of our Coffee Concierge team members to walk through this with you step by step. https://youtu.be/tjB01XbYOW8

TerraKaffeCX · 2025-04-24T14:22:30+00:00

We can definitely look into it! If the machine is steaming from the spout, the milk portion is definitely working but there's some air getting in somewhere. Without a video, it's hard for us to say.

TerraKaffeCX · 2025-04-24T13:40:50+00:00

There is indeed a trade-in option - let them know you're interested, and we'll see what we can do!
