Eureka Single Dose In Depth 

Dear Thomas, first of all, thank you for the video. We really appreciate your feedback and hints since these may allow us to fine tune our products. With this comment, we are happy to provide you and the community with our point of view on each relevant point mentioned in your review. Before going into details, we would like clarify that Mignon Single Dose has been designed to satisfy a specific type of use and need, that is Single Dosing. Considering this purpose, we believe that the most relevant aspect to be considered is the retention. In this regard, per your direct experience and review, we are pleased to underline that the results in terms of retention are extremely positive and (as you mention in the video) superior than other single dose grinders in the market. In particular, your result (around 0.2 grams) is very much in line with our test reporting an exchange retention below 0.3 grams. In addition, we would like to point out that low retention comes together with further relevant advantages, as follows: 1) Absence of grind static and anti-static dosing cup; 2) Very good taste and extraction in espresso (and also in filter coffee), due to the high grind consistency of 65mm flat burrs; 3) Eureka engine (AC motor) which provides higher performances and durability compared to other type of motor (i.e. DC motor). Here below our feedback point by point: • Concerning the Mignon Single Dose Blow Up Cleaning (bellow), being made of rubber and thus not rigid, it may be a bit hard to be placed on the hopper. Nevetheless, once it is perfectly placed, this is stable enough to be used even with energic blows (according to our field tests). BTW, thanks to your review, in order to simplify the assembly process, we are going to create a short video sowing all the steps and cares of this process. • Referring to the wooden lid, we would like to point out that the second production batch has been improved to create a better matching between the wooden lid and the hopper. Nevertheless, please take into consideration that, being made of refined wood, the lid is more fragile than steel or aluminum element. Just to make a comparison: when you buy something valuable such as a cristal goblet you are aware that this needs to be handled differently compared to a plastic glass (that is just an example 😊). Moreover, due to the “tricky” fit wit the hopper, we recommend to use it mainly with the blow up (rubber bellow). • About the hopper metallic tab, taking care of you feedback, we decided to add an additional cycle of polishing to improve both the aestethic and the usability. Taking into account the ease of opening/closing, please consider that our engineers specifically searched for this bit of resistance to make the tab completely fitting to the opening and thus reduce the vibrations/noise. • Concerning the noise, please allow us to say that the measuring method you have been using in the review is not really reliable. Moreover, it looks a bit unfair to compare the noise made by grinders with different motors specifications and performances. Nevertheless, like we did in the past for several of our grinders (such as Mignon Specialità, Mignon Silenzio, Atom Specialty…), we are going to evaluate the possibility to make a test with an external laboratory to calculate the noise level with the most appropriate tools and procedures. • Regarding the burrs regulation “issue”, it is important to mention that the regulation system of Mignon Single Dose is exactly the same of other Mignon, such as Mignon Specialità. In all our grinders, the spring is set to a certain preload level to provide the most appropriate feeling and usability while the user changes the grind size and it is not really clear to us which was the reason to modify the stroke of the spring. In this regard, we warmly suggest to not tamper with it as this may lead to the loss of the warranty. Generally, in case of supposed technical issue, we suggest to contact your vendor or us (info@eureka.co.it) to receive the proper suppport. • The single dose bean hopper is fitting to all the other Mignon models. Unfortunately, it turned out that the first produced units are a bit too loose compared to the required standard. We want to reassure you that the standard hopper will be perfectly stable. A small advice to increase the stability of the hopper is also tighting the safety screw in the back. To conclude, as mentioned above, Mignon Single Dose should be evaluated as a niche grinder, for a specific need. On one hand, it is not fair to compare it with “regular use” grinder like Mignon Specailità which has a completely different use (despite Mignon Specialità features a very low retention being a regular grinder). On the other hand, as you correctly mentioned, we can affirm that Mignon single Dose refers mainly to quite skilled single dose users, who look for professional performances and the possible lowest retention combine with unique desing and materials. For any clarification or question, please do not hesitate to get back to us. We take the chance to wish you all a fantastic 2022, full of peace and joy. Eureka Team

This channel was a good subscribe. So many other coffee youtubers are trying to be James Hoffman and failing at it. You're doing your own thing: dispensing quality content, respecting your viewers' time, and providing a perspective/voice that is actually unique. Hope you find success in the game - you deserve it.

Welcome! TLDR: it's excellent, but it's got serious issues. Still, I was able to repair it. Happy Christmas!!

Thanks for your review. I took delivery of mine 6 days ago, from Clive, after having had one on back-order from WWL for 2 months... Your experience is a bit different than mine, leading me to believe there is some variance in their build process. My bellows provides a tight fit to the acrylic hopper! It takes more than a little push to remove it. The hopper "open/close tab" is polished on both sides and seems well-finished. Note: this is the US model and highly-polished chrome.

What a brilliantly detailed review. And the best sort of criticism - you recommend and show how to fix the problems!

Superb review! Answered every question I had and more. The discovery about motor stability when tilted was genius.

Fantastic quality content as usual. Very informative and really helps with taking buying decisions. This channel is a hidden gem.💎 I wish you all success. Greetings from Tripoli, Libya 😊

I was waiting for this review and I’m going with Niche Zero. Thank you.

I appreciate your thoroughly elaborated language. It's a pleasure to listen.

Excellent review, far more in-depth than I expected, thanks for the insights!

Great video, so I’ve experienced a Eureka Oro XL that thing was a beast sent it back due to some wobbling the machine wasn’t braced properly, now have a niche that only a week old, was gonna snag on of these to compare which is better, seems like you saved me the trouble, detailed, technical, and honest. Thanks!

So far, I am very happy with my Oro Single dose (2023). Frankly, I have no complain about it and I am not paid by Eureka. It’s better than my Vario and for my use, I prefer it to the Eureka atom (too much retention and much longer grinding time). Retention is about 0.1/0.2 grams and the grinding is homogeneous and exceptional, delivering exceptional espressi with my Sage Dual Boiler.

If it wasn't for this video, I would have returned my Eureka Mignon Single Dose. I had to do the trick with the spring, and plan to check burr alignment in a couple of weeks. Thank you so much for doing this. The machine is now working as I would expect.

Gotta love this chill, slightly sarcastic kind of video.

Great review - am looking to get the single dose and a Flair 58 early next year. To get a flat burr grinder together with my hand grinder. I think I can live well with the few issues - how ever really cool you made so detailed review - could have been a frustrating encounter for sure.

Thanks for the in-depth review, makes me reconsider my oro mignon single dose preorder (especially the noise) but I'm sure there will be 3d mods available once it's in the hands of the majority. Might go back to the specialita if other reviewers reach the same conclusion as you did.

Great review, I just received mine yesterday (first grinder). I mainly use it for espresso and for that it's great. Personally I didn't have a problem with the fit of the lid and the bellows, I will check the sound levels later today. Edit: Sound without beans: 60dB, with beans: 78dB (also recorded with a smartphone) note this is an EU-model.

Well done absolutely wonderful coverage for this unit.. And big thumbs up for the Pfeil chisels 😍👍🏼

“Oh, my, god… it’s like a miracle!” 😂 I’ve been waiting for this review!! 🙏🏻

Thx so much for all your work!

Excellent technical review!

The greatest review thanks

Great video, and great content. I feel this was an honest review, hopefully they take it on board, because i am thinking of buying a new grinder

Good job on the review and teardown. Subbed

Great review!

"Superb" is all I needed to hear!!! I heard noting else that mattered. Mille grazie!! Thats all that counts for me!! I'm going to order right after typing!! Ciao!!

havent watch it yet. im so excited what u have to say. love ur channel❤️

Great review.

Very in-depth, good video!

This is really a great review. It was a real pleasure to see your video and it convinced me to keep my eureka mignon specialita.

REALLY GREAT REVIEW MATE KEEP IT GOING

Great review! I had big problems with a large amount of "mud" showing up when doing my V60 pourover, made me really dissapointed! I did the spring adjustment and will monitor the outcome. Looking at the initial test, it really helped a lot! THANK YOU! :)

Thanks for your indepth review

Impressive video!

Really well done video in my thanks for the information. It is interesting, as I already use a quality hand grinder and would need a very good reason to upgrade to a machine. I do suspect that people will always use a Niche grinder for overall quality and use

Just got mine a week ago and would like to add in my unit as a reference. 1) My unit actually did come with 4-5 rotations from the touch point to the knob "getting loose". I'm not sure if that's enough for filter, but certainly more range than the one in the video. Ill prob give it a shot and see If I have to mod it for filter after my "espresso phase" tones down. 2) My hopper gate did come with some sharp burrs as well. I just filed the edge for a few seconds, fixed it pretty quickly, but definitely should be addressed from the factory.

Another great video and I see your Moka pot videos are getting a decent amount of mentions on The Real Sprometheus channel. Rightfully so too

Great content as always :) Have two ideas what you could do next: opinion piece on temperature management with Cafelat Robot and the effect of placing a paper filter below the metal screen and above the coffee puck -- maybe with some tips on how to improve :D I've been forming my own opinion on these topics, but am not sure if my conclusions are also confirmed by others.

thank u for sharing

Great review. Also, I appreciate the way you pronounce specialita. So often, us English speakers get lazy. We can at least try with proper nouns, haha.

Hello Thomas, I really enjoy your content about coffee. Thorough, insightfull and a pleasure to watch. Thought you are American, but your channel says Ireland? Good voice anyway! Subscribed. Would you consider making a video about mods for the Mignon (Specialata)? Something I suggest experiencing: cotton pour over filters…. Please keep it up!

I think i am going to keep my old "Ascaso I-Steel i-1" till the end, bought 10 years ago (180€ new...), works always great with its 54mm flat burrs !

Your brilliantly detailed and insightful take on this is bound to blow any future reviews by others out of the water, and suffices to keep me from pre-ordering the Oro and saving up, instead, for the Niche as my espresso grinder to be. For the time being, though, I guess I‘ll have to just get a decent hand grinder, since the Oro was already a bit higher than my maximum budget for now. Any suggestions for espresso-only hand grinders? I briefly had the 1Zpresso J-Max and returned it immediately because the zero setting was hopelessly non-zero and I hate complexity and having to mod things right from the start. Just received a Timemore Slim Plus (with the E&B burr set, or whatever it‘s called) in the hopes that it‘ll work well enough for a medium roast in combination with the Picopresso.

This is James Hoffmann level of epic review…..seriously…I LOVE IT so much! Thank you!!! It’s a pity, I was so close to place a pre-order just to try my luck, but after this video, I think I will stick to my Baratza Sette 270wi for a little longer until they have the 2nd generation of this ready and fixing all the issues….really appreciated your review!

I bought this in March and these issues are all addressed. No vibration nor any loud or unusual noise to be honest. The hopper is stable too.

Thank you Thomas for such detailed technical review! this is really helping to see what is under the hood, now I understand how the grinder works and where the issues are, and how possibly to fix them. I have a qiuck question, you compared SD to Specialita. How do you see the actual Single Dosing performance for both Specialita and Single Dose grinders? I expect SD is better as it's designed for this purpose but is it worth to sacrifice the hopper and timer? I know a lot of people use Specialita as SD. What would you advise? Thanks!

Wow... this is the first video of yours I've seen. I found it looking for finally the first proper review. I'm still anxiously awaiting my Single Dose from the preorder. I'm delighted with the way you did it, and I completely identify with the details you're going for. I'm considering cancelling my order now! Lol! I currently have the Specialita however I don’t like it’s retention and I wanted to start with the single dosing. Can you recommend me a single dose grinder with flat burrs under $1000? Thank you !

Cheers for the review! Can I get the unit out in my specialita the same way to adjust the dialing knob spring? I find that when I go to the zero point and back and then again to the zero point it moves, is a bit somewhere else each time🤔. Maybe that spring loosend after two years of usage?

Nice detailed video thanks! I have a question would u recommend to mod Vario ceramic burrs to steel? If so why is there a big difference and do u have experience with ceramic burrs?

Thanks for the detailed review, I have a specialita and its a great grinder. Eureka do an amazing job with these grinders, with such a small foot print. Its really good to see reviews that get down to the detail. Thanks! Any chance you could do a similar review on the XL?

Looking for a single dose grinder that would also work for espresso and Hario v60 hand pours. Do I really need two different grinders??

Thanks a lot for that detailed test. How fine could you go? I have problems with my Silenzio not going finde enough, for light roast coffee, before touching burrs.

Have you considered a video comparing pressurized vs. unpressurized portafilters? This is one of those things that is hard for me to gauge if there is actually a huge difference between the two or if that is one of those just sort of "coffee truisms" that is just held like the filter rinsing nonsense. I've really been appreciating your content by the way! Thank you for offering a unique and insightful voice amidst all the noise.

Thanks for the review. I still own an old Eureka Mignon MCI and am looking to upgrade. Either to a Eureka Single Dose, to an Oro XL or to a Niche Zero. Your review doesn’t make the choice easier… as I understand it the Single Dose tastes better, but the Niche has the overall nicer grinding experience. What now!?

Thank yo ufor the thorough reiew that we have all been waiting on! Eureka should hire you as a consultant. You have also confirmed the Niche is a better choice for this particular subscriber.

Just wow. Amazing review. Thank you so much!

if i adjust the grinder too much it sounds really scary if they are touching, how can i find the right spot?... also every turn around makes feel the button harder to turn and then loose again

Thanks a million, great review, great camera work and full on-topic focus. Really curious what Eureka’s response will be on the noise level, 90dB over their 60dB claim, that’s a massive lie…How is that even possible???

Great review! Ever tried the DF64? Would love to get your in depth review on that too!

17:08 The "Gate Valve" is likely tighly fixed / slotted in so that air from using the bellows will leak out less. I imagine that valve will get looser with use, and with that looseness the air produced using the bellows will leak out of that slot more and more

Does the Eureka Facile have similar problems to the Oro Single Dose? How does the Facile compare overall to this grinder?

Thanks for the video. I received my Mignon a few days ago too and I tried adjusting the knobs spring and it doesn't seem to change anything. The grind range is very fine even when the knob is completely loosen. Thoughts?

This grinder has potential. Personally I love the look over any other grinder, and with some changes this grinder could be great. 1) They need to make the hopper not have that notch on the left so air doesnt escape the hopper when using the bellows. It makes the bellows almost useless. Also the set screw on the back which is supposed to hold the hopper in, allows air to escape and blasts the screw out. My screw doesnt even fasten to hold the hopper in, it just floats around. That portion should all be air tight in order to achieve maximum pressure when using bellows. 2) Make the declumper thinner, or different design to prevent clogging after each use. 2) Changethe way the front cover is attached or add a foam gasket seal with rubber washers housing the screw. The current design allows for motor vibration to travel through the housing via the philips screw. Better motor dampening, using rubber where screws meet the motor, or body would ensure a quieter operation. Just my 2 cents, afterall this is their first single dose machine, I expect their second one to be far superior and give the niche a better run for the money on the quality side of things.

Hi there - love your stuff - very nerdy but in a good way. I would like your opinion. I have a Bezzera bb005 conical grinder for home and am thinking of changing out ONLYT the burs - can you recommend any "better" option? Cheers

Great review very helpful. How is it compared it to ceado e5sd or df64?

Based on this informative video, am I right to understand that single dose doesn't make better coffee vs specialita? Taste profiles too similar? The larger burrs don't make enough of a difference? I'm a beginner who doesn't want to deal with modding the single dose mignon but I do want to practice single dosing. If that's the case, can a 3D printed single dose hopper + bellows make the specialita closer to being on par with the single dose mignon? Reason I ask is I cld buy a specialita today vs waiting months for the single dose mignon.

Hi! May I ask how did you manage to remove the screw holding the front plate that sits right below the adjustment knob? They completely overlap, making it impossible to reach it with a regular screwdriver...

you should look into the bellman stovetop steamers. mines pretty fun to use and works well with manual espresso machines. not too steep a price either for what it allows you to make imo.

Great review! Glad you checked the backwards compatible hopper. What about the grind dial knob? Can that be used on a Spec???

you're doing gods work!!! thats why i like comment and subscribe lol

Good day and very nice review, thank you very much. I have two configurations. The one at home: Niche Zero and Rocket Appartamento. The work side: Eureka Mignon MCI (with 50mm burrs) and the equivalent of a Lelit PL41 T Plus PID. I intend to change the grinder at work, so I'll change the Mignon MCI for a Mignon but I'm hesitating between the XL and the Single dosing. The XL would allow me to use the hopper and for the Single Dosing one finds on the net hoppers with bellows made with 3D printer whose users seem satisfied. In short, I hesitate between the two. But before an advice on this choice, another question: will the espressi be really better with 65mm burrs compared to 50mm burrs? Thank you for your help. Happy new year 2022 !

After tinkering around I realised that I could get retention down to about 0.1g by turning the grinder on/off repeatedly after the grinds stop flowing. Seems to work much better than bellows alone. I assume the change in momentum knocks some of the grinds off the burrs.

Thank you for the review! Quick question - the burr chamber & burr holder looks similar to Specialita. Any possibility of using that part to fit a 65mm burr into the Speciallita?

Dear Thomas, thanks for the video. I have a 6-months old Eureka Mignon Zero and suddenly I am not able to get a grind which permits me to get a decent cup of coffee. Moreover, I see that the knob has got harder to turn that it I do not know why and this does not allow me to really adjust the burr position. Why?

Thanks for the detailed review. I was thinking to purchase Eureka Oro Single dose until I saw this video. Now I’m back to research which grinder should I consider for espresso use. Suggestions are welcome! Any inputs on Ceado?

my local distrubutor told me that my pre order moved to batch 2, and only arrive on early Feb=.= this is a great video so that i can decide to just buy a niche zero and cancel the eureka single dose!

Great reviews on grinders so far on your channel, plus a lot of good info overall. Thank you for the hard work and efforts. What would be really great is if you could review the DF64 grinder. I have a Fiorenzato F64 Evo at the moment. It is the older model, but it's a beast, made all out of metal, at about 14Kg. I converted it to single dose, but i haven't solved all the problems yet. I am looking for a single dose grinder from the factory. I don't think i would like the taste from the Niche, as i mostly like the taste from flat burrs vs conical. After this review, i'm not considering the Eureka Single Dose. And yes, i have a Kinu M47 hand grinder. Apart from the manual labor, the experience is flawless and the retention is great, as you recomend in the video.

Awesome review mate. I noticed on my Single Dose that the upper burrs were scraping on the lower burr carrier, which added to the grinder noise (especially when empty). Have you noticed the same?

I have bratza forte that broke on me and I’m planing for an upgrade for my espresso machine Rocket 58. i had reviewed online eureka oro XL seems does well in retention and Clums. but, as per the reviews seems it might be a bit messy. What you think of the Single dose ORO comparing to XL is it less messy and quality? What about (celadon E37J) what you think of this comparing to you single dose oro XL? what is your recordation best for homeI’m looking for something that is… 1. Low retention. 2. Very low in clums. 2. Consistent grinding. 3. Easy access to bur for cleaning without the need to collaboration and alignment. Specially when i replace or upgrade the bur.

I've seen 3d printed tilt stands for mignons around the place. I love my little Mignon Crono. I got the old stock version with espresso burrs, and it's lovely.

How finely can the Eureka Oro Mignon Single Dose grind? I make espresso and some of the roasts I get need to be ground more finely than my Rancilio Rocky (modified with aftermarket burrs to go a little finer than stock) can manage. So, if I am going to spend the $$$, I really need a single does grinder that can go very fine.

Does the burrs regulation issue only happen to this grinder? Or this problem is likely to happen to all eureka grinders? I wanted to buy eureka zenith 65e, but after I watched this video, I'm in doubt to buy the zenith since all eureka grinders have the same grind regulation mechanism.

Great video! Please can you review Option-o Lagom Mini?

Received mine now, the hopper gate thing IS a bit stiff and not so nice to use. The single dose 3d printed hopper from my Specialita I had previously kinda seems to fit but not sure if it's making a perfect seal, i might test that out. The wood base is pretty nice and thick but the lid IS pretty thin and flimsy feeling definitely seems like one drop and it's a goner.

Hm. If you’re just using this for espresso and don’t mind the slightly slow speed, think the specialita might be a better bet? Seems like there’s more annoyances to this and louder than the Spet. Also, wishing you good health.

Hi Thomas, do you have problem removing the right screw on the ORO when opening the front cover for chute cleaning??

First of all, thank you big time for this video. Eureka should be buying this video copyright as their manual and online videos are so bad. they didn't even cover everything in details. Big help needed from you! I just cleaned out (actually not 100% clean still) my Eureka Oro Single Dose for the first time ever today. The manual was terrible because it didn't tell you how to open the top part. Anyway, when i first setup this machine, the manual asked me to tighten the screw to secure the hooper. before cleaning today, I removed the screw completely. the problem now is that I cannot tighten that screw back, its very lose even i tried many things. I suspected that i might dropped a washer or something. any idea? also, i don't see that you tighten that screw in your video. thanks!

You can have the Specialita on an angle with good stability and it’s still as quiet as can be.

Thanks ! Can we use it for V60 and Espresso too ? 😁

So I just got mine and omg I can’t dial it in for the life of me at one point I had it shooting out balls lol but I’m almost there I should of went and got some cheap beans

Would love to see a head to head comparison of this grinder with the Ceado E5SD. Unfortunately there seems to be almost no interest in the E5SD...

Sweet, basically I was looking for a bigger Specialita and if it's got similar taste profile I think this fits the bill. Larger burrs should give it a better grind consistency I'd think. It doesn't seem like issues are really 'that' big of a deal, well besides not being able to adjust very coarse (I think it's supposed to be an espresso only grinder isn't it so they probably did that on purpose?). It's probably best to use the wood lid with the bellows if it's hard to get in and out of the hopper part. Hopefully don't drop it or it's the plastic one as a backup! :O

Very nice review :) One question was unanswered: How much retention does the Specialita have?

Why are there always so many coffee grinds inside Eureka grinders?

What are everyone thoughts on how the hopper connects to the machine. There is a notch to line up at the left (9 o'clock position) viewing from the top with the front facing you. The rubber seal was made to shape around it but no matter how low or hard I push the hopper down on my Oro Single, that small gap will leak air when compressing the bellow. There is actually more air coming out of that gap then the chute itself which is frustrating and defeats the design. When I asked for a return, the local store respond stating "The Eureka grinder is designed this way it does have a hole from which the air will escape in order not to vacuum seal with beans inside" and wants an 18% restocking fee. My personal dislike (knowing prior to purchase) is the dummy switch below the chute and dummy fork insert fitting carried from Eureka other grinders such as Specailità. The noise I can manage, better then my AP30.

So if I’m just using this for espresso do I need to fix anything with the nob lol

What happened to the video about Christ in renaissance art? Can’t find it anymore. 🤔

I have the same issue with retention: I ran about 4kg of different coffee from different roasters (light and medium roasts) through the SD since december 24, but every time it clogs the grinder and the blow of does not help at all. It just can't make enough pressure. I have to remove the hopper every time and use a proper uniersal aliexpress blow rubber - this blows out about 1,1-1,3 grams of stuck fines. I have much better experience with my Niche... Very disappointed in EUREKA..

No wonder it shakes and wants to jump off the counter. The motor assembly isn't isolated properly from the chassis. There's a lot more components that seem to be an afterthought rather than a deliberate design choice. Is this an Italian machine by any chance?

As you cone across as a person with vast amounts of knowledge, I would like to reach out to you as I am not getting much help from Eureka Italy. My eureka Mignon MCI is 11yearsold and suddenly started clogging up. I at first thought it might be the burrs so change them but it's still doing it. I am at a,loss for solutions. I don't want to throw the machine away and furthermore don't know what to buy as a replacement. You speak highly of the Eureka Oro SD....
