1Zpresso J grinder "The repackaged JX Grinder"

[@vitalyplatonov6050]

Thank you for the thorough comparison! It is my first grinder from 1Zpresso and I was really confused why it screwed back on each time at a different setting. Now I see it's by design like this, thank you for the help!

No problem you are very welcome and i am happy that the video helped you. Unfortunately this type of grinder has a fixed adjustment dial and can not be calibrated like other grinders that have a removable adjustment dial. So you are kind of stuck with the number that you have when you close the burrs completely. It is possible to move the 0 number closer to the starting position by taking it off and then moving the metal pegs on the underside around to the next hole, this will also move the number that you have when closing the burrs. There are three pegs and one of them should let you move the 0 number very close to the starting position, so try all three and see how close you can get. Mine gets the 0 about half a number away, but thats good enough for me, its better than landing on 6 or 3.

Thank you this is very helpful. I have the J and was confused until I watched this😊

[@mightymightyironhead]

You are very welcome, happy that the video helped.

I have updated J manual and am hoping you can do a video explaining how you dial in for an espresso? I understand it's better for pour over but if possible I would appreciate it. I can't find one.

@@LKB728 let me ask you a cpouple of questions first, maybe i can answer your questions about how to dial in for an Espresso without making a video, if you are still jot sure i can certainly consider making a quick video. There are really two types of Espresso depending on what machine you are using and what type of porta filter (coffee basket) you are using. In cheaper Espresso machines and manual Espresso makers, there is the pressurised porta filter, this is very easy to dial in the grind size for, because the pressurised porta filter does most of the work for you, so you do not have to be very precice with your grind size. Then there is the none pressurised porta filter, this is harder to use and harder to dial in for, because you have to be more precice with your grind size, so you need a decent grinder with good fine grind adjustments (smaller microns). So can i please ask you, what type of Espresso porta filter are you using, are you using a pressurised or a none pressurised porta filter? Fot the J grinder the settings on the grind reference chart for Espresso are 08 - 11 (08 is 8 numbers from o (closed burrs) to 11 (one number past the first full rotation of the adjustment dial) this give you 3 numbers to play with. However if you are using a pressurised porta filter it is a lot easier to dial in a shot because a pressurised porta filter allows you to use a more course grind size. So you can then use a grind size that you would typically use for something like a Moka pot or Aeropress and that will still work very well with a pressurised porta filter. In that case you have quite a bit more grind adjustment that you can use for Espresso, from 08 - 2 (number 2 is two full rotations and the end of the grind range for Moka pot and Aeropress) Please note that 08 is obviously the finest setting and is more likely to be too fine, while 2 is the most course setting and more likely to be too course, but for a pressurised porta filter you have a very large grind adjustment range to play with. The problem with using a grinder like the J grinder for Espresso using a none pressurised porta filter is the micron size is a little too big (J grinder has 25 microns). So the steps (or clicks) are not so precice for small fine adjustments. To have a good Espresso grinder i recommend a grinder with at least 16 microns, better is 12.5 or best 8 or 0 (stepless adjustment). So for Espresso using a none pressurised porta filter with the J grinder, you have the numbers 08 - 11. Depending on what beans you are using and what roast level. Darker beans are easier to dial and mean that you can go a little more course within the grind settings. Light roasted beans need to be more fine ground, so you would need to go for a more fine grind setting. So if you are using a none pressurised porta filter with light roasted beans, try for around 08 - 09 (you might have to go a little finer, but start there) If you are using darker roasted beans, 08 - 11 or 12 (you have a little more grind adjustment to play with if the beans are darker). Anyway i hope that helps, if there is anything you are not sure about, please just let me know and i will do my best to explain.

@mightymightyironhead WOW! Thank you so much. This is the information I needed. I just got a Breville Bambino machine. It came with both the pressurized and non pressurized baskets. I have been playing around with both and you were exactly right. The nonpressurized basket is much easier to work with when grinding with the J Manual. I just didn't understand why. Your information makes so much sense now. You are awesome and thanks again! Do you have a favorite grinder you use?

[@mightymightyironhead]

@@LKB728 you are very welcome and i am really happy that the information was useful for you. Yes there can be quite a big difference between the pressurised porta filter and the none pressurised porta filter. Like i said above, the pressurised porta filter is a lot easier to grind for, because the machine is really helping to decice the correct pressure, so you can use courser ground coffee powder. The problem is with the fine grind adjustment of the grinder that you are using, so for proper none pressurised Espresso its very important to get a grinder with smaller microns (16 microns or below is best) There are a few grinders that are good for all brew types, including none pressurised espresso. I deal with 1Zpresso because they make some of the best manual grinders on the market. The 1Zpresso X-Ultra has 12.5 microns, this is an excellent all round grinder and has a decent grind range for none pressurised Espresso, this micron size is also very good for Pour over, because its not so fine that it produces too many fines (very dust like coffee particles) that can effect the draw down speed of your Pour over and effect the flavour too much. They also have the J-Ultra, this is a very good Espresso grinder, it has 8 microns, so it has a huge grind range for Espresso to play with. However like i said with the X-Ultra, although the J-Ultra can be used for all other brew types including Pour over, because it has very fine microns, it can product slightly more fines for Pour over, so take that into account. There is also the Kingrinder grinders. They are pretty decent grinders and most of their K series range have 16 microns, this is the top of the micron size that i would recommend for none pressurised Espresso, but it will give to a small but useful grind range to play with. After that, they really is not a lot of manual coffee grinders that are available for both Espresso (none pressurised) and Pour over, often you get a Pour over grinder, that can be used for basic pressurised Espresso and not None pressurised Espresso. Or you get an Espresso grinder that can be used for Pour over, but has the issue for the extra fines. Then you have the expensive electric prosumer top of the range grinders that often also can not a be used for both things, unless you pay extra for a second set of burrs. So right now there still is not such a great choice for a manual grinder that is truly a grinder for everything, apart from the few i mentioned above. A couple of things that you can try to help you with your Espresso if you can not get the grind size dialled in properly. Dosing. Try dosing up (under extraction) if your extraction is too fast because the grind size is a little too course, even hafl a gram more can help to get the little extra pressure. Likewise dosing down can help if you have too much pressure. Play around with your dose until you get the extraction right. Darker roasted beans are always easier than light roasted beans. Typically darker roasted beans can have a courser grind size than lighter roasted beans, lighter roasted beans are a pain and they typically need a more fine grind size to get a good extraction. You also need to adjust your water temerature more hotter for light roasted beans, so maybe experiment with regular darker roasted beans and keep away from light roasted beans for a while. Try a Slow flow basket instead of a none pressurised basket. Slow flow baskets have slightly sloping walls instead of straight walls that you have with a regular none pressurised basket, so they sit inbetween a pressurised basket and a none pressurised basket. Because of the slightly sloping walls, the pressure is directed slightly to the center of the coffee bed and this can really help if your grinder does not have the fine grind adjustment needed for a regular none pressurised basket, it will make it easier to get a good extraction and give you more grind adjustment to play with for your grinder.

Thanks for the great review. Couldn't find any other videos talking about this specific grinder.

[@mightymightyironhead]

You are very welcome, happy you found the video useful.

[@audunforfaen]

Hi, thank you for your very explanatory videos on the 1Zpresso grinders. I am a bit annoyed with the company’s crappy webpages and manuals following the QR-codes. I have been trying to understand which grind charts to use having bought the “J manual coffee grinder”. Neither of their charts shows anything marked just “J”. Would your assumption be that I should use the chart marked for Jx?

[@mightymightyironhead]

Yes i totally agree with you that 1Zpresso just cannot seem to get their website together and make is user friendly, its really the reason that i started posting these video's. Basically the J Grinder is a reissue of the JX Grinder (with a couple of changes) so the grind reference chart from the JX Grinder is 100% the same as the grind reference chart for J Grinder, so you wont have any issues using the JX chart for the J grinder.

This video could have been 3 mins long

[@mightymightyironhead]

Show me, how about you go and buy the two grinders and make a video to explain the differences between the two grinders in 3 minutes. When you have done that, send me a link to your video and i will critique the video.
