1Zpresso JX-Pro Coffee Hand Grinder Review

[@davidd.6448]

Got mine couple of weeks ago and I'm really happy with it. I can finally use my Flair Neo's 2-in-1 bottomless portafilter instead of the pressurized one and produce some really great results.

[@needmorebeans]

I think 1zpresso's grind setting convention is A.B.C; where A=full rotations, B=number, C= Clicks between numbers. For example, an espresso grind could be 1.5.2

[@AlternativeBrewing]

Yes, much like the Kinu as well. Much easier way to track and share settings 👍

[@BillyBobpeeps]

I’m equally a fan of your expertise and of this grinder. This is a great overview and it was generous of you to create the vid as I’m sure your encouragement will help this manufacturer to create even better kit. Some additional points are worth noting to demonstrate some of the detail in design. Some beans, for some reason, will gum up the burrs unless one shot of water from an aerosol is pumped on the beans half way during filling. This ‘gumming’ can regularly happen in a smaller way as indicated by the appearance of a few tiny clumps in the grinds bin. For this reason, it might be best to always apply a pump of a water aerosol during hopper filling as a matter of course (one pump equates to less than ½grm water). This will also ensure zero retention and consistent grinding. The outside of the grinds bin is of a perfect diameter for tamping 58mm baskets. The top of the bin is of a good enough fit to transfer the grinds to the basket without spill, clumping and any localised compaction (in the above vid timeline 3.22 - states it’s not a good fit - true, it’s a little loose but it works exceptionally well - if it was larger here, there would be penalties elsewhere.) ‘Dialing-in’ takes a max of three attempts and could be a reflection of this machine’s extraordinary consistency. I’m just an ordinary punter and if I appear a bit draconian on detail, it’s your fault as I’ve studied all your vids. I’ll gladly continue to do so to learn more as you never waste a word. Many thanks.

[@AlternativeBrewing]

Right on! Thanks for the kind words and excellent additions to the details of using the JX-Pro grinder 😀

[@teramonte7077]

Liked the actual testing in out on screen, thank you 🙏🏼

[@ThePinkPanth3r]

Mine is out for delivery today, excited.

[@AlternativeBrewing]

Nice!

[@TheModsen]

I also own and love the JX-Pro for espresso with the Flair Signature and regular black coffee with the Aeropress :)

[@AlternativeBrewing]

Perfect

[@mediaFRIENDS]

I have also JX-Pro and it is one of the best tool for my special coffee. Really is great.

[@AlternativeBrewing]

Totally agree!

[@tristanmccoppin5761]

Dude you grind like an athlete! Very graceful

[@AlternativeBrewing]

I appreciate that!

[@9abe9]

Very nice video! Just one important thing to note: I think you have a new version of the Jx-Pro, becouse the top piece is different, and the inner burr is accessed via unscrewing. The version I've got is built to be disassembled without tools, only by rotating the adjusting know coarser and coarser, until the bottom burr pops, and the manual states that that bottom screw should NOT be unscrewed!

[@AlternativeBrewing]

Hi Gabriel, thanks for your feedback. You'd be right - we went one step too far! So you do NOT require to remove the nut at the end of the burrs - you only need to unscrew everything from the top and the drive shaft will fall out the bottom. Thanks for picking this up 😀

[@holliedekraai4137]

Is the jx-pro good gor just pourover? Or, do you recommend something else?

[@AlternativeBrewing]

For Pourover I'd go the X-Pro over the JX-Pro 👌 JX-Pro is more suited to Espresso

[@AviationEducationChannel]

Getting into this world just now - I am thinking this grinder and a Breville Bambino to keep things affordable. I've been told this would be a solid beginner setup for someone coming from Nespresso pods lol what do you think?

[@AlternativeBrewing]

100% yes 😀

[@timmccutcheon4080]

That is exactly why I'm here. I have a kitchenaid grinder set on espresso and the bambino empties the 18g portafilter in 10-15seconds. My drill powered porlex does better at 20-25 seconds, but it's still unable to grind fine enough.

[@rjejames28]

This grinder is so impressive, I love it.

[@AlternativeBrewing]

It really is!

[@gustavokudo]

How's the J-Max? Only good for espressos? (cause of more fines he makes). So JX-Pro would be more a All-around grinder? (pour over, espresso, french press,...). Cheers

[@AlternativeBrewing]

They're pretty close. I'd say yes, JX-Pro is the better all rounder 👌

[@TomsCoffeeCorner]

Hey there! How did you get that cool transparent timer on your video? Been looking for something like that. Nice video for sure! Tom

[@AlternativeBrewing]

Premier Pro - time code effect - adjusted to the FPS and then Crop the 00:00:00 you don't need 👍

[@TomsCoffeeCorner]

@@AlternativeBrewing Awesome, thanks for sharing! I use FCPX, but maybe I can find something similar. Cheers! Tom

[@OIP_1]

this video pushed me over the edge to buy one of these (from you guys), great clear and to the point! definitely prefer the idea of a manual grinder vs electrics in the same price range.

[@AlternativeBrewing]

Good choice! Thanks for watching

[@eglin62]

Hello and thanks for the excellent review/tutorial. One question regarding grind time. I really liked when you showed the grind time for espresso, but did you have a good estimate on grind time for a typical pour over grind for 20g? Thanks much.

[@AlternativeBrewing]

Thanks so much! Yes, absolutely . Quicker 😀 like 20-30% quicker than the Espresso grind. The reason I demonstrate the Espresso Grind time - is ait is the finest setting that is hardest to grind at - so in doing so you can see it, at its hardest setting and take from that any else will be quicker and easier

[@mrxyo]

I have JX and it's awesome, but just I wish I have purchased JX Pro for more adjustment.

[@AlternativeBrewing]

Totally agree

[@manuelpenaruiz3694]

And better grind quality (not by much but still significant) According to 1Zpresso, the center burr of the JX-pro is attached to the shaft for "improved consistency, uniformity and grind quality overall"

[@DanTopPhotography]

How do you go about using a drill on this? Can the top be closed or must it be used open?

[@AlternativeBrewing]

popcorning could occur if you use it open - especially if using a drill that will significantly increase the RPMs. However I'm aware this is quite a common approach with the 1zpresso grinders. I've done it myself - but wouldn't do it as a regular thing - Im happy with hand cranking tbh. To answer your question - you do have to have it with the lid off to use a drill.

[@meltroha]

I have a Timemore Slim Plus with the E & B burrs, love it for all pourover brewing, however I just got an espresso machine and am having a hard time dialing it in. Do you think it would be a big enough improvement to buy this, when I already have a grinder that costs $140 USD?

[@AlternativeBrewing]

Yes yes yes. 100% improvement. I talk about he Timemore grinders being good for espresso - but they do have their limits. If you're chasing a hand grinder for espresso brewing that'll replicate good results - close to those of using an automatic grinder - the the JX-Pro, the J-Max or the K-Plus are our picks for sure

[@nadyaharyanto7182]

I had same situation like you. Because i bought flair classic, my slim plus can't grind fine enough for the flair. I decided to buy jx pro and sell my slim plus. Jx pro is bigger and a lot heavier than slim plus, quite surprised when my jx pro arrived. Grind size uniformity is much better on jx pro. Both for espresso and pour over. If you do both espresso and pour over like me, i think jx pro is the absolute winner. Sorry for bad english

[@TheTylerianmitchell]

Commandante C40 with RedClix Upgrade vs 1Zpresso JX-Pro. I believe the price difference really just comes down to brand/style. Functionally very similar. I chose to save a £100

[@AlternativeBrewing]

Great point!

[@paolodeang7103]

Is getting a kplus a big jump from a jx pro? We do espresso and pour over alternately at home

[@AlternativeBrewing]

No, not a big jump. JX-pro has a wider grind selection. I wouldn't upgrade to the Kplus if you already have the JX-pro and are grinding okay with this. Remember - the JX-pro has 12µ change , the Kplus 22µ .... but the flavour profiles are unique enough you may be looking to experience what the Kplus has to offer, which is fair enough

[@paolodeang7103]

@@AlternativeBrewing thankyou very much for input. Will take your advice and we will stick to jx pro. :)

[@mediaFRIENDS]

Perfect and beautifully explained.

Glad you liked it

[@gautam.shankar]

How many seconds do you have to work it for pour-over?

[@AlternativeBrewing]

30 seconds max i reckon

[@Scientifiste]

hi!!! would recommand this one or kinu Phoenix to pair with a flair expresso machine? thx

[@AlternativeBrewing]

Both! But I'd go the Kinu Phoenix if the extra expense is not an issue 👍 Just overall higher quality build in the KINU

[@zalmansad1729]

It's also super easy to clean

[@murselduz6520]

Hi Did i missed? Can you tell me adjustments towards to clock direction?

[@auroragoh8323]

Hi, clockwise to reach zero point(near very tight to absolute tight) and then loosen in anti clockwise to change settings to coarser.

[@Wongway99]

I would like to buy my first xpensive hand grinder for pico presso. I need your suggestion. Which is better k-plus or jx pro or it’s enought to use q2 i’am beginer btw. Please helm me : ) some time i used for pour over, mokapot or aeropress

[@AlternativeBrewing]

I'd go the K-plus for sure

[@andresdigi25]

I got this grinder. But i do not understand how works the grind settings. 60 clicks for expresso, but how i know what is the starting point?

[@AlternativeBrewing]

Dial the grind changer back as fine as it will go - this should then be at sero using the dot on the inside of the hopper as your sight. 60 clicks is 1 full rotation and two number coarse. (there are 5 clicks between each number) Hope this helps 😀

[@alexchernikov6276]

Is there a reason why top bearing thumbscrew is upside down in your video? i.e. the ball bits normally go on the bottom

[@AlternativeBrewing]

those ball bits are on the bottom - it just looks lit they're on top 😀 itwon'tt screw on any other way

[@tolga1cool]

Just got mine today. Amazing grinder for the price. I was using my porlex mini for a while and was rather unhappy with the performance in grind uniformity and grinding speed. The JX Pro is so much better that you can't really compare the two

[@AlternativeBrewing]

Great to hear! I agree -there's really no comparison between ceramic burr hand grinders and metal ones 😀

[@rogerpye1865]

Another great review,. How much does it weigh?

[@needmorebeans]

Just weighed mine, 790g including the handle

[@AlternativeBrewing]

780g

[@rogerpye1865]

Thanks, sorry I didn’t wait for the end of the video to ask the previous question. Do you think that it is of a size that would make it suitable to travel with?

[@auroragoh8323]

@@rogerpye1865 depends on what bag are you carrying in your travels,and how do you orientate the grinder within the bag.

[@MegaScheids]

Thx for the video! I just bought one and it looks great. However, the handle only runs smoothly untill 3 full rotations. Above 3 it starts to be draged a little, which comes more when turning up to 5. So at 2 rotations of the grind adjustment, the handle goes around freely when I give it a little push, but around 4 rotations the handle will rotate for 2 "laps" and then stops. Is this normal?

[@mikele7982]

Hi friend, as an owner of JX-Pro myself, I have not seen your situations yet. However, for my personal use, I haven't used any click after 4 rotations and my max would be around 3.6.x to 3.7.x (Rotation.Number.Clicks-after-number) for French press and coldbrew. So I urge you not to worry about those if your grinds are still as consistent as ever with smooth adjustments and easy dis/assembly. Stay well.

[@ElectTheChopStick]

I have never used a hand grinder before, can you explain what clicks are exactly? I am kinda lost

[@AlternativeBrewing]

Clicks is another way for saying settings. There are different settings to change the distance of the burrs in order to attain finer or coarser coffee. Clicks / settings / dial position are all interchangeable terms used to set your grind size.

[@DennisKooimanGomes]

Thanks for the great review. I like to buy one to use with my Moccamaster KBG. What grind setting do you recommend?

[@AlternativeBrewing]

Thanks! With a full batch I use a setting of 35 👍

[@chefarj]

How about on what metal, hrc of that burr grinder? Likewise on comandante c40 burr. I'm more interested on how long will the burr last

[@AlternativeBrewing]

Great question! This doesn't seem to be discussed alot across the hand grinder range. One reason for this would be it's very likely the burrs, made very similar to commercial burrs - the big difference being the volume of beans you'll be placing through both of them ... if they were rated to say 700kg - than you'd be getting 35,000 doses from the hand grinder before considering changing burrs. In a commercial environment that's an amount that's viably attainable - but in the home setting its years and years before you'll end up using that amount. However the C40 buurs does correlate to longer use with less decline in the peak range of performance for the burrs... so it goes from say 6 years to 10+years as an example ...but it's a significant amount of time to place on the burrs ... one day I imagine all burrs will be create in a way it won't matter ...as they all have a lifetime of sharpness to them ...

[@manuelpenaruiz3694]

Materials engineer here: JX-pro burrs will last for decades in a home environment. It could take decades actually. Remember we are grinding coffee not rocks!

Nervous laughter to fill the awkward silence

[@Gavin_May]

I’ve had a jx pro for a year and a half and I’m not impressed. I’ve gotten it to work for me but to grind you have to have a full grip across the entire grinder. The rubber grip portion is threaded to another portion of the grinder and when you go to grind it will adjust the grind without touching the dial. If you don’t have large hands to hold the entire bottoms portion then I’d get something else. Also the magnet came out of the handle and I have to use a cut yogurt cup to efficiently dump the beans into the grinder and usually they get stuck in the adjustment dial. Mine you literally can not grip the way this guy did in the video or it will lock up the grinding mechanism because it will adjust to the finest setting.

[@AlternativeBrewing]

Wow! ok ... I;ve honestly never heard of this issue before. What do you use now instead?

[@Gavin_May]

@@AlternativeBrewing I still use the jx pro because since I already spent the money I don’t see a point in upgrading. After commenting I cleaned the grinder and really put some torque on the reverse thread parts of the grinder and it seemed to mitigate my issues but i know one day in the future it will come loose and i will have to readjust it which would suck if I just want some coffee in the morning and not wanting to play with my grinder

[@mikele7982]

@@Gavin_May Hi friend, I think yours is a defective one. You should ask your retailer or email 1Zpresso directly to fix it. For the beans stuck on the dial, I had those at first, but then I use the catch cup to store the bean, then when pour beans in, I inverse the whole cup to the grinding chamber, hold it there, give it 3-4 shakes. Beans will automatically drop out of the dial. Hope this help. Stay well.

[@manuelpenaruiz3694]

When a grinder brings acidity up to the front that much is because it's signature particle distribution is actually narrow and focused. Acidity comes from under extraction, among other factors. You can easily find that a cheapo C2 yields a sweet and enjoyable cup while a top tier like the K brings more acidity (and maybe more brightness. This can be bad or good, up to owners preference) Your go-to grinder should be selected based on your taste buds alone. Let your buds guide you. The most expensive unit would not suit your flavor preference. From a certain (build quality) point and beyond, the thing comes down to buyer preference. Theres no better or worse: just different amigo! (As an example, Comandante is not the most precise grinder, but its signature particle shape and distribution produces a unique, very distinctive flavor. This is why it has been praised for professional and home baristas all over the world) Jx and JX-pro are amazing grinders and when had the chance to make my choice I went for the JX-pro and I'm so happy I did. My pour overs are what I want: sweet and complex, fully bodied, very neutral acidity and very low retention. Build quality is second to none and TBH I see no reason to upgrade to K series (unless my top priority was bells and whistles!)

[@BennyCFD]

Manual grinders take forever to grind. If you're getting into burr grinders go electric.
