- A quick unboxing of the new J-Ultra. Plus some comparisons to the original J-Max and some of my thoughts at the end.
1Zpresso have been busy over the last year. Discontinuing a lot of their grinders and also releasing a few new ones.
Right at the end of the year they announced that they were going to discontinue the J-Max espresso grinder and then reissue the grinder as the J-Ultra.
The J-Ultra has a totally different design, similar to the K-Ultra and feels more comfortable in your hand. The J-Ultra includes the new S series grind handle and the newly redesigned travel case.
Its some internal changes like the new magnetic strip instead of the regular small magnets.
It also has 8 microns instead of the 8.8 microns that you got with the regular J-Max, so slightly more grind range for your Espresso.
Good and very informative video and in-depth comparison of the two and the case. Thanks. Unfortunately there seems to an issue with the tone. Sometimes there is no sound at all which I find a little bit a pity. Also the ongoing background noise of incoming mail on the Mac I find a little bit distracting. But apart from that, very good video indeed. Thanks again
Thank you, very detail explain the J Ultra grinder, going to get this grinder.
Still waiting for my J-Ultra to be delivered, thank you very much for the detailed review, was a bit concerned because there aren't many reviews out, but looks like it's a great grinder. Can't wait to use it!
You are very welcome. Hopefully i covered everything in my video.
The J-Ultra is an excellent grinder and one of the best Espresso grinders you can buy.
If you need any more information about the grinder, just drop me a message and i will be happy to answer any questions you have.
you'll be fine. It's basically a VERY slightly tweaked J-max, and the J-max has been overwhelmingly positive in terms of reviews. anything the J-max can do, this one will do just fine.
@@user-yk5ln8lp2v received it last week, it's so much better than my previous Timemore C2, I'm so happy that it doesn't take 10 min to grind for espresso, really good grinder
Great video and comprehensive coverage! Thank you for all the details! ☕
You are very welcome. Thanks for the positive feedback.
Thanks, it seems a bit more comfortable to hold, compared to J-Max. I have medium hands, so I don't really have problems withJ-Max's body, though.
So, I guess if you want comfort and fancy stuff you get J-Ultra, if you don't need that and want to spare some money, you get J-Max.
But it makes me think, why exactly 1zpresso just can't stop themselves from redesigning older grinders? It takes money and time to make them, yet they pop them out like hotcakes.
I totally agree, 1Zpresso can be pretty confusing, i have been selling their grinders for year and i dont understand half the things that they do.
It can be a pretty painful experience trying to get a straight answer out of them also, so i try not to ask them too many questions.
I have a theory about why they have changed the shape of the grind handle and the body shape also. Its got to do with another big grinder company who has a habit of trying to claim copyright and IP infringement on other companies.
I think that the handle at least is a big issue with this situation. I think that they have also realised that they have too many grinders that look the same and do the same thing, so they are trying to fix that.
The J-Max will not be available soon, it is discontinued, so the only option will be the J-Ultra.
Yes the JE and the JE-Plus was discontinued quite a long time ago, when they released the K-Max they discontinued the JE and JE-Plus. Too be honest i dont believe half of what 1Zpresso tell me in regards to when they discontinue their grinders and the availability.
They have stopped me ordering some of these "discontinued" grinders and over a year later they are still selling them directly from their own website.
Yes i was hinting at Comandante, they have been very aggressive with a lot of companies that either try to release new products or have released coffee grinders.
Comandante seems to think that they own the patent for all manual coffee grinders and the shape of the parts, such as the handle. But they dont. They threaten to take a lot of companies to court over this and a lot of companies just dont have the money to fight them with a counter law suite.
Thats news to me that Wacaco are not going to release their IMS basket, i did not hear anything from my Wacaco agent about this. They actually have promotional material out that shows the actual basket, so they at least got that far. I will email Wacaco and ask them about this and update you.
@@mightymightyironheadThey actually re-released the JE PLUS again ... Amazon has it listed with the new S handle and 1zpresso's site has the older fixed handle JE-PLUS up there.... for $189 I grabbed one to compliment my J-max. I've heard those Italmill burrs on the JE were amazing and rivaled the Kinu M47
I really miss the JE and especially the JE-Plus, they are really decent grinders. I still get asked a lot if i can get the JE-Plus, its still a very popular grinder for Pour over.
@@mightymightyironhead I talked to 1zpresso and they said they're bringing it back. But the one difference is that they no longer are using the italmill burrs in it but are are their own in house clones of them. I picked one up on wednesday and it just shipped. I'll give it a whirl as I hear it was one of the better espresso oriented grinders they had
Should I Grab the J ultra to upgrade from my K ultra? I have no problems dialing in espresso with the K ultra, but would the J ultra produce a better tasting espresso?
Too be honest both the K-Ultra and the J-Ultra are physically very similar, i have had some very nice shots of Espresso with both grinders and like most things coffee, its not that easy to tell any difference between the two unless you are testing them side by side.
If you have some money to burn and you want a dedicated Espresso grinder and a dedicated Pour over grinder, you would notice some difference between the two grinders.
I if you are happy with the results that you get from your K-Ultra and dont need that extra fine grind adjustment for dialing in, its a pretty big cost for a little extra flavour.
There are a couple of things that do mean that both grinders will have differences in flavour, not just for Espresso, but also other brew types and the obvious thing would be the micron size.
8 microns for the J-Ultra and 20 microns for the K-Ultra is absolutely going to mean that you will have different flavour profiles using the two grinders for each brew type.
For example, the J-Ultra can produce more fines because of its very fine microns adjustment, so that can be an issue for Pour over. But again from my testing its really not that significant and it can actually help with some types of beans and some roast levels.
Another thing that does slightly change the flavour profile between these two grinders is the coasting on the J-Ultra burrs. I personally do think that coated burrs do have an impact on the flavour in cup and produce "a purer flavor" but again it is not that much or that noticeable, especially between two top end grinders, it would probably be more obvious between one of these grinders and a cheaper grinder.
Lastly, there is a difference between each burrs again. The K-Ultra burrs have small cutting edges all the way up the sides of the blades and the J-Ultra has small cutting edges half way up the sides .
These small cutting edges are there for grinding efficiency, heat management and particle size distribution ect ect
I wrote this to explain about different burr types because i get asked a lot obout this type of thing, it might be super boring, but there are a few thanks that might be interesting and help explain what i am talking about.
Full-Length Cutting Edges (K-Ultra):
Half-Length Cutting Edges (J-Ultra):
Here are some reasons why cutting edges might be present all the way up the blades in some designs and only halfway up in others:
1. Grinding Efficiency
Full-Length Cutting Edges: Burrs with cutting edges all the way up the blades can provide a more aggressive and faster grind. They are often used in grinders designed for high-throughput settings where speed is a priority.
Half-Length Cutting Edges: Burrs with cutting edges only halfway up may be designed to create a more gradual and controlled grinding process. This can lead to a more consistent grind size, which is important for brewing methods that require uniformity, such as espresso.
2. Heat Management:
Full-Length Cutting Edges: These can generate more heat due to the increased friction and contact area. This might not be ideal for delicate coffee beans where maintaining a lower temperature during grinding is important to preserve flavor.
Half-Length Cutting Edges: By reducing the contact area and friction, these burrs can help manage heat better, leading to a cooler grinding process that preserves the coffee’s aromatic compounds.
3. Particle Size Distribution:
Full-Length Cutting Edges: May produce a wider range of particle sizes, which can be desirable for certain brewing methods like French press or cold brew that benefit from a mix of fine and coarse particles.
Half-Length Cutting Edges: Aim to produce a more uniform particle size, which is crucial for brewing methods like espresso and pour-over that require precise control over extraction.
4. Durability and Maintenance:
Full-Length Cutting Edges: Burrs with more extensive cutting surfaces might wear out faster due to increased friction and contact with the coffee beans.
Half-Length Cutting Edges: Can be more durable and require less frequent replacement, as the reduced contact area minimizes wear.
5. Manufacturing and Cost:
Full-Length Cutting Edges: These can be more complex and costly to manufacture due to the additional machining required to create the full-length edges.
Half-Length Cutting Edges: Simpler and potentially more cost-effective to produce, making them a popular choice for many mid-range and entry-level grinders.
The choice between full-length and half-length cutting edges in conical burrs depends on the desired balance between grinding speed, heat management, particle size distribution, durability, and manufacturing cost. Each design has its own advantages, and the best choice depends on the specific needs and preferences of the user and the intended use of the grinder.
I wish they would replace to plastic disc cover with a solid metal one that matches the body. No plastic!
Yes i agree, i understand that they make it so that you can see how many beans you have in the hopper, but a lot of people dont like the plastic one. I used to have an aluminum one for my JX-Pro that i got made for me, it cost me a few quid to make and was perfect.
@@mightymightyironhead Why do you need to see the beans in the hopper? You can feel how many beans are in there by shaking and grinding. No plastic! For me, the BPlus Apollo is still the best hand grinder ever made.
I agree, i dont really look down into the hopper to see how many beans i have left to grind. However the plastic disc is also to prevent popcorning and stop the beans from jumping out when you are grinding, so i suppose that these discs do serve a function.
The BPlus Apollo grinder is a great grinder, I actually very nearly started to deal with BPlus and sell their grinders. Too be honest i am not a big fan of the "Roman column" shape of the Apollo, but the grinder is very nice to use. It reminds me a bit of the Kino grinders, but without the step less adjustments that the Kino grinders have.
I disagree. It will be scratch or chip easily when putting it on/off endlessly and I would hate that more
You mean the metal disc will scratch easily? I agree that the disc can be scratched if you are not careful when putting the handle on and taking it off.
However the way that the handle is designed and where the disc is attached to the end of the handle means that the disc should not rub against the body or even the top of the burr shaft.
Thanks for the informative review!
Any idea of its compatibility with the manual lever Cafelat Robot?
I just wonder if the grinder magnet would stick to the 58mm robot basket when transferring the coffee from the magnetic catch cup
In an ideal Cafelat robot world, you would be able to grind directly into the robot basket
Thanks!
Hi good morning. The J-Ultra is an excellent Espresso grinder and the 8 micron grind adjustments are more than enough for your Robot.
Regarding the J-Ultra magnetic catch cut sticking to the basket of the Robot.
The robot basket diameter is 58mm and the diameter of the J-Ultra catch cup is also about 58mm, so yes the magnetic catch cup will stick to the Robot basket.
The actual magnetic grip is not that strong, its strong enough to hold the basket securely and you can safely lift the basket with your ground coffee inside, but it does not have a lot of resistance when you pull the catch cut away from the coffee basket.
So i would recommend that if you want to do that, use both hands while you are attaching the catch cup to the basket and while you are tapping the grounds into the basket, but other than that it works very well.
Can you give details regarding the taste for espresso for medium, medium-light roast especially for example with K series generally better with lighter roasts or lean towards acidity over sweetness, as well if taste has improved vs J max? I’m curious how maybe J ultra is similar to kinu or lagom mini espresso for medium roasts that balance decent depth flavor & sweetness versus more fruity acidity. Thank you
I’m not sure which one to choose. I don’t make espresso, only pourover. but I like the characteristics of espresso grinders that enhance sweetness and body.
So
I’m really in doubt: J-ultra, K-ultra or ZP6.
If you only really do Pour over the ZP6 is a "Pour over only" grinder, ok it can also be used for French press, but according to 1Zpresso, its a Pour over only grinder, meaning that you can not use the grinder for other brew types like Turkish, Espresso, Aeropress, Moka pot, drip or, syphon.
1Zpresso claim that the ZP6 has the best flavour profile for Pour over.
I will have a shipment of ZP6 grinders arriving within the next week or so and i will make a video showing the grinder, what it looks like and what it does.
The K-Ultra is a better option if you want to use the grinder for other brew types. The K-Ultra has 20 microns, so its able to be used for proper none pressurised Espresso.
However in my opinion 20 microns is great for Pour over, but is not the best for Espresso, but it will give you something to work with, especially with an Espresso machine that allows you to swap out the coffee basket from pressurised to Slow flow to none pressurised.
None pressurised obviously giving you the least grind range adjustment to work with.
The J-Ultra is really an Espresso grinder first. Its got 8 microns, so its got very fine grind adjustment and a very big grind range for Espresso.
However the downside with this very small micron size is that it will produce slightly more fines at the medium and course grind range, this can sometimes be an issue for Pour over, because more fines can change your draw down speed and that in turn can change your flavour profile.
I would say that the amount of extra fines that the J-Ultra produces is negligible, but it does produce more fines than other grinders with bigger microns.
The flavour profile is slightly different to the other grinders with bigger microns, but in my opinion its not that much different and really not bad, but its worth pointing that out.
@@mightymightyironhead thank you for the amazing explanation! In The perfect word, I’d buy zp6 + j-ultra, but I’m a beginner, so I think the best choice would be k-ultra for now!
The K-Ultra is an excellent grinder for Pour over and its a very good grinder for a beginner. Like i said above the only limitation this grinder has is the 20 micron is not as good for serious Espresso as you would get from an actual Espresso.
But a lot of people do use the 1Zpresso K series grinders for Espresso and are very happy with the results. They often start with a manual Espresso machine like the Flair or the Robot and then upgrade from the stock basket or a slow flow basket to a none pressurised basket later and the K-Ultra is good enough for that if you decide that you want to explore Espresso later.
Anyway good luck on your coffee journey and feel free to message me if you need any help with your new grinder.
@@mightymightyironhead again, thank you so much! I have no doubt anymore 🤜🏻🤛🏻!
Happy to help.
I have been throwing the idea of a hand grinder for travel now for quite some time…was a pourover only guy…but seeing the short video released recently on Flair go coming soon, I am actually now very much considering a hand grinder. Obvious choices now would be k-ultra, j-ultra and now going initially from first to last is zp6. How do you see finish holding up on dark grey model over months and years of use?….also between j-ultra or k-ultra, will the extra fines produced with j matter for pourover….currently I’m split right down the middle as to which one to go with. the extra time switching from pourover to espresso setting is irrelevant to me. seems weird the j-ultra is cheaper in price.
Both the J-Ultra and the K-Ultra are excellent grinders but there are some important differences between the two grinders.
The coating on the dark grinders is very good quality anodized metal coating. I have a J-Max that i have used every day for the last two years and the colour has not worn off at all, also i have never had anyone contact me and tall me that their colour has worn off, so i would say that its pretty safe and unless the grinder is getting some punishment, the anodized metal coating is pretty solid.
The only criticism i have is the hand grip material, i think that 1Zpresso should change this material, in my opinion, it looks a little cheap and could be better quality.
If this material get excessively wet (wet hands or spraying water while spritzing) or you live in a country with a very high humidity, then the material can develop dull patches after a year or two.
There are kind of three different types of 1Zpresso grinders.
The Espresso grinders (J-Ultra and the discontinued J-Max grinder)
The Pour over grinders (Q, J, K-Ultra and the other discontinued K series grinders)
And the "all round" grinders (X-Ultra and the discontinued JE-Plus, JX-Pro and the X-Pro grinders).
Firstly, the J-Ultra is an Espresso grinder first and foremost. It has the 48mm coated burrs and 8 microns, so you have a very big grind range for Espresso.
However like you pointed out in your comment, the smaller micron size can and will produce slightly more fines at the medium and course grind range, this is not a major issue and you often work around that, but it does impact the flavour in the cup.
I want to stress that its not a huge impact and depending on the beans that you are using and the roast level of the beans, it might even enhance the flavour, but it does produce more fines and that grind range.
1Zpresso are a strange company, i also don't know why they have the price for the J-Ultra pretty low, its actually the same price as the discontinued J-Max, but the Ultra has the much better travel case and the redesigned body is a lot better to hold, sometimes its best to just not ask questions haha
The K-Ultra is very similar to the J-Ultra in looks and design, its pretty much got the same body.
However the K-Ultra had the bigger 20 microns and this makes it arguably a Pour over grinder.
The K-Ultra can also be used for Espresso, but when you start to move more towards the finer grind size for None pressurised espresso, the fine grind adjustment for those 20 microns obviously are not going to give you the same ease of dialing in your espresso as the J-Ultra with 8 microns.
However you do still have a small but decent amount of fine adjustment for Espresso with the K-Ultra.
It works pretty well with manual Espresso machines like the Flair Pro, ROK and Robot ect, with their stock slow flow baskets and also pretty well with the same Espresso machines if you swap out the stock baskets and use a precision basket instead.
Also with the K-Ultra you dont have the extra fines that the J-Ultra produces at the Pour over grind range, so you get a very nice flavour profile.
There is another alternative. The X-Ultra is what i would consider an "all round" grinder. because it has 12.5 microns.
This smaller micron size is perfect for both Pour over and Espresso and its not that often that you find manual coffee grinders with this micron size (most coffee grinder companies want to spilt the micron size between Pour over and Espresso so you need to either but two grinders or two sets of burrs).
With a grinder with 12.5 microns you have a pretty decent grind range for proper none pressurised Espresso, but you also dont have such small microns that you are getting the extra fines. So this is a very good option if you really want a grinder that can be used for both Pour over and Espresso.
The X-Ultra is also a little smaller than the J-Ultra and the K-Ultra, so its pretty good for travelling. The other two grinders are not so heavy or bulky, especially with their hard cases, but they are quite large and to be honest i never take mine out with me or travel with them, but i would consider the X-Ultra over the other two if i had to take one.
Lastly, the ZP6 Special is pretty much the best manual Pour over grinder on the market. However it can only grind for Pour over and French press and it can not be used for any other brew types.
Anyway i hope that answers a few things, if you have anymore questions, please just drop me a message and i will do my best to answer.
@@mightymightyironhead That is honestly the best information I have received thus far…thanks for taking the time to include so many details. I will now add the x-ultra to my list as it actually seems best fitted for me….travelling with v60, Flair Go and x-ultra appears to be a great combo
@@MadScientist7 No problem you are very welcome.
sorry for the late reply, CZcams is awful at notifying you when you have a message.
The X-Ultra is definitely the most compact and easiest grinder to carry around and with the travel case it’s a nice little package that can be put into a backpack or suitcase and not be a pain.
The X-Ultra is also the easiest and fastest of the 1Zpresso grinders to calibrate (the J-Ultra and the K-Ultra are not too shabby) and can be calibrated in seconds.
It’s definitely worth checking it out and doing a little more research to see if it’s the best fit for what you need. If you need anymore information, please feel free to message me and I will do my best to help.
I've yet to actually find a video that shows me HOW to use the grinder! The videos all seem to be about taking the grinder apart !
To be fair i think that most people that make these type of video's assume that most other people who are interested in manual coffee grinders already have an basic understanding of how to use the grinder.
The basics like what end to put the beans in and what end the ground powder comes out is the same for pretty much all manual grinders.
After that there can be a few things that are a little different, but not entirely different between most manual grinders.
The size and type of burrs can be a little different from grinder to grinder, but fundamentally they all do very similar things, the calibration between grinders can be slightly different, the dismantling and reassembly can be slightly different, but not that difficult to understand, then you have things like the micron size, this can be very important to each grinder and will determine if the grinder is more or less able to adjust for Espresso.
I always try to include as much information as possible without making the video 2 hours long and getting complaints from viewer and also trying not to hold my viewers hands too much and assume that they dont know the very basics.
If there is something that i have missed out of one of my videos i always do my best to answer any questions or comments about the grinders, i am also very open to any suggestions for things that i might have missed or things that people want to see included in future videos.
So if you have any questions or need any help with using any of the grinder, i am happy to help you with that. If you have any suggestions for something that you would like to see in a video, please let me know and i am happy to also include that.
Bedankt
Thank you so much for your kindness and support. Your generosity means a great deal to me and I am deeply grateful.
Great video! Are there plastic parts in this grinder?
Thank you for your positive comments. The only plastic part is the popcorn guard, it’s a hard plastic disc on the end of the grind handle that stops beans from jumping out of the hopper when you grind beans.
Other than that there are no other plastic parts on the grinder at all.
There are no other plastic parts at all
How about the ease of cleaning compared to the J-Max and K-Ultra? Especially on the threads inside of the adjustment ring? I had to sell my J-Max because my hands are too small for a good grip. Particularly on those spots when the adjustment ring is not fully closed, there is buildup of tiny bit of aluminum dust, caused by friction. The user experience was great though.
Hi i would say that the cleaning and maintenance for both grinders is about the same.
The J-Ultra obviously has a different adjustment dial to the J-Max, the Ultra's adjustment dial is very similar to the K-Ultra or the K series grinders.
There is also a space where the threads are just inside the adjustment dial for the J-Ultra.
The threads are slightly different to the ones for the J-Max, the J-Max adjustment dial is kind of flat on the inside where the threads are and when you open and close the adjustment dial, you see either more or less of the threads depending on how much you turn the adjustment dial.
The Ultra is a little different, when you look down into the space inside the adjustment dial, the dial is flat and then it tapers out when it gets to the threads, so the threads seem to be more visible and "open" and i suppose that it would be a little easier to get coffee particles into the threads because they taper out and are more open.
However, this also means that they should be easier to clean, because you can see them better and they are easier to actually get at with the cleaning brush.
@@mightymightyironheadThanks so much! Do you think that the K-Ultra visual dial indication on the top works better than indication with pyramid blocks on the sides of the J-Ultra and J-Max? Or is that premium feature of the K-ultra?
Too be honest i personally dont think that it makes any difference when you are dialing in your grind size. Both grinders have the pyramid squares on the side, obviously these have two functions, one is to tell you visually how many rotations your burrs are open and the other is for calibration.
The J-Ultra has both the numbers and the dots below the numbers (side not top) 1 . 2 . 3 . ect these dots line up with each number and also they line up with halfway between each number, the J-Ultra does not have any dots on the top of the dial because the top of the dial is too thin.
The K-Ultra is slightly different, the K-Ultra has the numbers on the adjustment dial (side) it also has the dots that fall between the numbers on (side) the top of the adjustment dial has the dots that fall on the numbers (but not between the numbers) its pretty much the same and both grinders are really the same but laid out slightly different.
I think that this is just a visual feature, outside of a visual reference that you probably wont really use that much, its just looks a little nicer on the K-Ultra (for me anyway).
@@mightymightyironheadThanks a lot Paul! I appreciate your detailed answers and also all the dedication you put in your video's to provide info that is hard to find elsewhere!
Thank you also for your extremely generous donation, that's so kind of you and its genuinely appreciated and thank you for your kind and positive comments.
J max and J-Ultra burr are the same? What about their pour over performance?
Hi, yes the inner burrs for both grinders are the same (48mm 6 core coated burrs) however the J-Ultra does not have the burr cap on the end of the burrs and the J-Max does have the burr cap.
Its the same for the outer burrs, they are the same for both grinders, as far as i can see, 1Zpresso have not changed the inner burrs to the sharper burrs that they have with the X-Ultra and X-Pro.
Regarding Pour over, Both of these grinders are primarily Espresso grinders and you need to take that into account when you are buying these grinders.
The J-Max has 8.8 microns and the J-Ultra has 8 microns, so they both have very fine grinder adjustments.
Because of this smaller micron size, they will produce slightly more fines at the medium and course grind range, so this is something that you need to be aware of for Pour over and French press.
However this is not significant and you still get a very good flavour profile using both these grinders for Pour over.
Hello i have the j ultra and i had the j max before. Fir my j ultra, i don t know if i have a problem because it s work at 0 .9.5 rotation and it s under the 1zpresso advices for expresso how are between 1 and 1.7 rotatation. What do you think please ? I calibrate my grinder to 0 berore to use. I had an issue with the wood handle and 1zpresso send me a new but they are not sure for the futur it makes me afraid a little.
Hi, i dont think that you have anything to worry about.
The grind settings (0 .9.5) that you say that you were using with your J-Ultra might seem like they are quite fine, that setting is right at the start of the Espresso grind range, but this is not unusual for Espresso.
However its not unusual to have to grind finer than you would think for Espresso, sometimes certain beans just need a finer grind size for them to work.
Also it depends on your roast level, light roasted beans typically need a finer grind size than medium or dark roasted beans, so its really not unusual to go that fine.
Also both of these grinder have different microns sizes and this also affects the grind size and the number of clicks you have for each rotation, so the numbers that you use for one grinder wont be the same.
The J-Max grinder has 8.8 microns and the J-Ultra has 8 microns, so the grind settings will be slightly different between both grinders.
Settings are:
The J-Max has 9 numbers per full rotation and 10 clicks between each number, giving you 90 clicks in total.
The J-Max the Espresso grind range starts at 1 full rotation (90 clicks) and ends at (150) clicks.
So for the J-Max any grind setting between 90 clicks and 150 clicks will cover all types of Espresso.
The J-Ultra has 10 numbers per full rotation and 10 clicks between each number, giving you 100 clicks in total and 500 clicks covering the 5 full 5 .
So for the J-Ultra the Espresso grind range starts at 1 full rotation (100 clicks) and ends at (170) clicks.
So for the J-Ultra any grind setting between 100 clicks and 170 clicks will cover all types of Espresso.
However please remember that the Ultra has the 8 microns and the J-Max has the 8.8 microns, so typically the settings will be less than what you might have used for the J-Max.
If the grind works ok when you are using the grinder and there is no obvious issues, if the Espresso is extracting properly and the grind size that you are using is working for your Espresso machine, i dont think that you need to worry about the slight difference in the grind size and numbers between each grinder.
Thank you very much and do you have issue with the wooden ball? Mine comes off every time. 1zpresso sent me a new one but I'm afraid for the future. @@mightymightyironhead
Yes i have seen this happen before with the wooden ball on the end of the handle. There are two reasons that this can happen.
The first one is the small magnet that is in the hole in the wooden ball has fallen out and the handle has become loose and not so tight when its used.
The second and probably the most common reason is the plastic insert in the wooden ball has become misshaped over time and the ball becomes loose when you use the grinder.
There is a small plastic part inside the hole in the wooden ball, over time this plastic part can become loose and the handle comes off easier when you use the grinder.
I think that part of this issue happens when people don't hold the grinder properly when they are using the grinder. Its best to always hold the grinder as straight as possible when you are grinding, if the grinder is not straight, this can put uneven pressure on the handle at certain points and the small plastic insert in the hole can become lop sided and misshaped over time.
I can help if you hold the grinder more straight when you are using it (this is also better for your burrs) and also dont turn the handle so aggressive and try to grind so fast, this is not a fix, but it can help to not make this happen, or stop it from happening so quickly
I personally think that this is a bad design and i do hope that 1Zpresso look into changing this, maybe use a harder material for this insert
In terms of burr alignment, can you check the number of clicks it takes from burs start touching to a full lock. You can easily do it without crank being fitted. Thanks
Sorry i am not 100% sure what you are asking?
Are you asking how many clicks it is from the burrs being fully closed (zero point and calibrated) normally and the point where the adjustment dial has been turned too far and the burrs are toughing and have locked up?
When the adjustment dial is turned too far, the burrs will lock up and you will not be able to move the adjustment dial until you use tools to unlock the adjustment dial.
When you are calibrating your grinder and turning the adjustment dial to get the 0 number into the correct position, its important that you feel for the start of the resistance, the adjustment dial should be "finger tight" you can check this two ways.
One is with the grind handle on the grinder and turn the grinder on its side, if the handle falls, the burrs are still open, if the handle stays in position, the burrs are closed.
You can also check without the handle being one the grinder. If you take the catch cup off, you can use your free handle to try and turn the burrs with your fingers.
Again if the burrs turn, the burrs are still open, if they do not turn, the burrs are closed.
I would say that when you have turned the adjustment dial to calibrate the dial and the adjustment dial is in the correct place that it should be, you can also open the adjustment dial a few clicks (until you can turn the burrs) some people like to do that because they worry that the burrs are touching.
At that point (when the burrs are closed and calibrated properly) if you keep turning the adjustment dial, i would say that it would be about 15 - 20 clicks (maybe 2 numbers) before you would have issues with the adjustment dial and burrs locking up.
Setting a zero point on the adjustment dial is entirely arbitrary. You can set it up at 0 on the adjustment dial when burrs start touching or when you reach a point of no movement at all. I'm interested in number of clicks between these two set points: first touch of burrs (then 1 click counterclockwise on the adjustment dial giving you a bit firmer touch of burrs, then more counterclockwise clicks eventually preventing a full spin but allowing for a less and less right/left/right/left movement) until there's no movement at all. This alignment test should give you full range of burr misalignment in the number of clicks. Unless, of course, your grinder is perfectly 100% aligned.
You are 100% correct, setting the 0 number on the adjustment dial is entirely up to you, really its just a visual guide, you can of course just turn the adjustment dial all the way until the burrs are closed and use whatever number you have at that position as though it is the 0 number.
Usually i turn the adjustment dial until i feel resistance and the burrs can not be turned with my hand, or the grind handle stays in place if i turn the grinder on its side, i use this as a way to decide if my burrs are closed enough to be at what 1Zpresso refers as the "zero point/starting point".
1Zpresso say: "We define it to be at the point when you feel resistance while turning the crank handle instead of the tightest of the adjustment dial".
Basically that are saying the same thing as me and this is usually what i follow when i am using my grinder and calibrating my grinder.
When you turn the adjustment dial to close the burrs completely, at the point where you feel that resistance and you would stop (or even turn the adjustment dial back a few clicks until the burrs are slightly open because some people dont like the thought of the burrs touching) and then calibrate the grinder using the thumb nut.
At that point when you feel that resistance and the burrs are closed, if you continued to keep turning the adjustment dial, you would maybe get about 10 - 15 clicks or so, before i would say that the burrs are really touching, but its not recommended to do that, because you can really lock up the burrs and its very difficult to unlock them again.
If you are asking about misalignment of burrs, i honestly dont think that my own personal J-Ultra has any issues, it grinds extremely well, its consistent and does not feel like its pulling to one side, or making any strange noises.
Also i have used my J-Ultra quite a lot (its replaced my J-Max as my Espresso grinder) and i have not had any issues with dialing in the grind, or any movement over time, but this could change over time after using the grinder for longer.
I have not heard of any others talking about misalignment issues with their J-Ultra either, but again its early days. If you think that your grinder has this type of issue, i recommend that you contact either the dealer that you got the grinder from or 1Zpresso direct and they can give you better advice than i can.
I'm glad you've got that. So what is the range in number of clicks between burrs start touching to a no burr movement on your grinder? Hope it's not too much to ask, Thanks.
for me it seems like its 1 click between slight movement and no movement at all. But bare in mind that i dont tighten my adjustment dial really tight and your tightness might be slightly more or less than my tightness.
I can still turn the burr shaft at 1 click away from 0 (burrs fully closed at zero point) but its quite tight and i can feel it rubbing.
If i turn the adjustment dial that 1 click to the 0 number, i can not turn the adjustment dial at all unless i force the adjustment dial to move (at this point obviously the burrs are not touching).
If i go 1 click past the 0 i can not turn the adjustment dial at all (because the burrs are touching at that point).
Hi ! Can you please recommend how many click you use j ultra for picopresso ? Thank you ;)
Hi, the J-Ultra Espresso grind range starts at 10 (1 full rotation) and ends at 17 (1 full rotation and turn to the number 7)
The Picopresso uses a slow flow coffee basket, this basket has a slightly sloping wall and this helps to push pressure to the middle of the coffee basket, its kind of in between a pressurised basket and a none pressurised basket.
These baskets are useful if you do not have a great grinder with good Espresso fine grind adjustments, however your J-Ultra has very good fine grind adjustments.
Depending on the type of beans you are using (lighter roasted beans tend to need a more fine grind size than medium or dark roasted beans)
I would personally start at the more course end of this grind range and work my way finer if needed. So maybe start with 17 and adjust a number at a time until you get a good extraction.
18 gr coffee 1.5.5
And what about Kingrinder K6 ? It’s same or not ?
The Kingrinder K6 is a pretty decent grinder for the price.
The K6 has the 48mm 7 core Heptagonal burrs and these are the same type and size as the J-Ultra, however the J-Ultra burrs are coated and the K6 burrs are not coated.
The J-Ultra has 8 microns and the K6 has 16 microns, so the J-Ultra is much better for dialing in the grind size for Espresso. The K6 can still be used for proper Espresso (none pressurised) but you wont have a very big grind range to play with.
Bare in mind that the 1Zpresso JX-Pro and the X-Pro both have 12.5 microns and these are both not really considered Espresso grinders, they are considered all round grinders, but they both have smaller microns than the K6, so are better for Espresso with more grind range to play with.
The Kingrinder grinders used to be manufactured in the same factory as the 1Zpresso grinders, i am not sure if that is still the case. They are pretty well built and are pretty solid and consistent when you are grinding.
I would say that for the price they are a decent choice over some of the other grinders in that price range, simply because they have the smaller micron size right across their range, even the cheapest Kingrinder grinders the K0 and the K1 (before they introduced the P0 and P1) have 18 microns and that's better than the 1Zpresso Q2 or the Timemore C2 and C3.
Would i but the K6 over the J-Ultra, not really. If i had the money for the J-Ultra i would buy that grinder. If you want an Espresso grinder, the J-Ultra is one of the best Espresso grinders that you can buy period.
The J-Ultra looks and feels better, its got a better build quality over the K6. Its got the coated burrs, so the burrs will last you longer. Its also got the very nice new travel case included.
If you have a tight budget, the K6 is a very decent grinder. its very good for Pour over, and i would say that its a very decent all round grinder.
However with 16 microns its going to have a small but usable grind range for proper none pressurised Espresso.
So if thats what you are looking for the K6 might be perfect for you.
@@mightymightyironhead wow man ,thank you so much ;) your answer it’s amazing !!!
@@mightymightyironhead I need grinder for my picopresso and maybe I will buy j ultra
The J-Ultra is by far the best 1Zpresso grinder for Espresso because its got the 8 micron fine adjustment. Its got a very big grind range for Espresso and if you need to adjust the grind size to get the absolute best shot, the J-Ultra can do that very easily.
If find that you are on a tight budget and the price of the J-Ultra is a little too much for you. Both the JX-Pro and the X-Pro both have 12.5 microns and can also be used for proper none pressurised Espresso, so these two grinders will give you good results with the Picopresso.
The Picopresso uses a slow flow coffee basket, this basket is a little easier to use than a regular precision coffee basket, because the walls of the slow flow basket are not straight walls and they slope slightly into the middle, this forces the pressure into the middle of the coffee bed and can help to build pressure a little more than a regular precision basket.
This is useful for people who dont have the best Espresso grinders with the super fine grind adjustments needed for Espresso, so if your grinder does not have great fine grind adjustments, this type of basket can help with that. But you do still need a decent grinder with at least some decent fine grind adjustment and the smallest micron size you can find, so i do recommend that you do try and get a grinder like the J-Ultra of at least the JX-Pro or the X-Pro.
@@mightymightyironheadthank you so much !! I will buy j ultra
It's perfect for turkish coffee
Yes it does grind very good Turkish fine grind. It can be a good way to build up you arm muscles also haha
