1zpresso JX and JX Pro – a Detailed Review of the Two Sibling Manual Grinders

Few things in life beat the pleasure of the first cup of coffee in the morning (or at 3 AM, we don’t judge). But a crucial part of making that happen is to have the right tools. And one of the essential tools to make coffee is the grinder. After all, who doesn’t love the smell and flavor that only comes with freshly ground coffee beans? (That’s right, no one).

Do you want a grinder with a reasonable price and excellent quality? Of course, you do! So for today, we’ll be testing out the JX and its older sibling, the JX Pro.

1zpresso JX and JX Pro – a Revolution in Manual Grinders

Now to be fair, manual grinders are usually slower and require more effort on your part as compared to electrical ones.

The JX series, though, is a revolution in that sense. The 1zpresso JX and JX Pro are much faster compared to most manual grinders. In fact, their speed and efficiency even beat some electrical grinders.

Both models have the same stainless steel burr, but there are a few significant differences.

Long story short, if you need a grinder to brew pour-over coffee for the most part, then the JX would be perfect for you. But if you’re someone who likes their daily cup of espresso, the JX Pro is the way to go.

The JX series offers great consistency and is pretty fast for a manual grinder. It is also cheaper than most of its competitors, making it a pretty good deal in itself.

Who Is 1zpresso?

1zpresso is a relatively new coffee grinder brand based in Taiwan. Their primary focus is on manual coffee grinders. With the JX series, the brand has set the bar high for other manual grinders.

This is especially true when we consider the price-to-quality ratio these models offer compared to their competitors.

Everything You Need to Know About the 1zpresso Jx and Jx Pro – Full Review

For most of the previous manual grinders I’ve tested, the small capacity of the burr is always annoying. It makes the workflow for larger batches much slower since I have to grind, refill, and grind again. Spending that much time just grinding coffee isn’t what I want to do with my life.

The number one thing that attracted me to try out these grinders is that they feature a stainless steel burr of 48mm. This allows for excellent speed and capacity, saving a lot of time and effort.

Now without further ado, let’s get started with a detailed review of the JX and JX Pro:

Design of JX and JX Pro:

Let’s be honest. We all appreciate well-designed products. Something could have excellent functionality, but if it looks bland, nobody wants it in their home.

Fortunately, both JX and JX Pro have a great design in terms of looks and function. They are sleek and well-made. The classic silver-grey color has been an aesthetic addition to my kitchen. The product is made of full aluminum. It was initially glass, but the company changed to aluminum later because of the replacement complaints they received.

Since these grinders’ diameter is extensive, it is vital to have a good grip that makes them easy to handle. For that reason, both JX and JX Pro have big wooden handle knobs comfortable to hold even for extended periods. Being slightly longer than most other models, they provide better leverage and grip to the user.

Overall, both grinders showcase great build and ergonomic designs. They are also highly functional and easy to use. With these features, grinding is almost effortless.

Quality of JX and JX Pro:

In my experience, I did not get any wobbly parts of the grinder even as time passed.

I’ve used it for more than a few months now, and the internal pieces are still doing great without coming loose. Most of my previous grinders struggled with this, so it’s an absolute delight to see the JX series doing so well.

Moreover, both the JX and JX Por come with a one-year warranty which further adds to their reliability.

Size of JX and JX Pro:

Size is one of the few things where the basic JX and JX Pro show a significant variation.

Firstly, the JX Pro is slightly taller than JX. It also weighs more than its standard (and cheaper ) version. Both the standard JX and JX Pro have a capacity of 35 grams.

The dimensions of the standard JX version are 5.12 x 2.24 x 6.22 inches. The product weighs a total of 630 grams. On the other hand, the JX Pro has dimensions of 5.12 x 2.24 x 7.09 inches. It weighs 780 grams.

What’s Inside the JX and JX Pro?

1zpresso is well-known for its superb bearings, and the JX and JX pro didn’t disappoint.

The bearings on the inside of the grinder are incredibly smooth. The two bearings provide an ultra-smooth spinning action. There is a stainless steel burr that makes the product easy to use and handle.

Portability of JX and JX Pro:

When it comes to portability, JX and JX Pro don’t exactly fit the criteria.

I wouldn’t describe them as portable, simply because they aren’t built for that purpose.

With the JX weighing 630 grams and the JX Pro being 740 grams, the products aren’t explicitly travel-sized. That being said, you can bring them along on a long trip if you’re okay with the extra weight.

Adjustment of the JX and JX Pro:

When it comes to adjustment, the standard JX and JX Pro have their fair share of differences. This is probably the only fundamental difference between the two models, but it makes a fine distinction for the users.

Overall, the JX grinder has a pretty good adjustment. It works on a reasonably simple mechanism. It uses little clicks for each rotation. The dial has a total of 12 numbers on it. However, the grinder also offers a half step between each number. Effectively, this gives you a total of 24 clicks per full rotation, which is a pretty good number for its build.

When it comes to the JX Pro, the adjustment has a significant number of variations. For starters, the dial is now on top of the grinder. This puts it right where you pour in the coffee beans, making it quick and straightforward to switch between the coarseness settings.

Secondly, I found that the Pro’s micro-adjustment is far more precise than the standard JX model. It offers a much greater number of increments on the dial. Instead of 24 numbers, as with the JX, the JX Pro gives you 40 increments per rotation. Each click shifts by 12.5 microns, giving you 100% accuracy control over the grind you want. The adjustment dial is also pretty responsive and offers a smooth, luxurious experience. Who doesn’t love that?

Consistency of JX and JX Pro:

When we talk about consistency, I could go on for days about how good both models are.

I don’t like to exaggerate, but I mean it when I say both JX and the JX Pro offer pro-level consistency. Both of them give excellent and pleasing results that are an absolute delight for my coffee-loving taste buds.

I didn’t notice any significant difference between the JX and JX Pro, so it’s safe to say you’d get great results with either of them. The internal fixing between the burr and central shaft of both models provides impressive consistency. They give a uniform particle size for most of the grind, which many manual grinders struggle with.

There was a pretty low drawdown time with both of the grinders since no fine particles could clog the filter. The draining time was also significantly reduced, offering a great experience overall.

Speed of JX and JX Pro:

Let’s be clear: I’m not the most patient person in the world. So I greatly appreciate it when machines do their jobs without making me wait for hours (what feels like hours, anyway). For both of the JX models, they’re fortunately both swift. I did, however, find it surprising that the standard JX is faster than its older sibling. In fact, I would say the JX is the fastest manual grinder I have tried so far.

I tested this out by grinding my usual 15 grams of coffee. According to my measurement, it took around 18 seconds to get the process done, which is a modest improvement over most other manual grinders. The JX Pro is slightly slower than the JX version, but it isn’t that noticeable. (Unless you’re picky about speed, a.k.a. Me).

However, there is one thing I noticed in my use of the standard JX. 1zpresso claims that both versions have the same burrs, but the ones on JX seemed a little more energetic than the JX Pro. Although this adds to the fast speed, it also requires a lot of strength to shift the crank.

This shouldn’t be a problem in daily use, but you may find it challenging to deal with once you get to the higher part of the dial. When on the more refined end of the spectrum, the burrs are a lot closer to each other. In return, this means you will need more force to turn the handle.

All in all, I prefer the standard JX version in terms of speed. But if you don’t particularly care about a few extra seconds, I recommend going for the JX Pro because it provides more ease in handling and turning.

Ease to Clean of JX and JX Pro:

The JX series grinders make cleaning a breeze, no lie. It’s incredibly convenient to dismantle the grinder’s pieces since it doesn’t even require any tools. You can simply rinse each piece with water and soap.

1zpresso also provides a cleaning brush inside the package for free, making the process even more straightforward. Putting the pieces back together isn’t a problem either, as it is with most other grinders I’ve used.

The Noise of JX and JX Pro:

Silence is golden. This takes a whole new meaning when you’re the first one awake in your house and want to make coffee. Thankfully, the JX and JX Pro are some of the quietest manual grinders out there. The series offers a smooth and seamless grinding mechanism, making minimal noise in the process.

Espresso vs Pour-Over Coffee?

Now just to be clear, 1zpresso advertises both JX and JX Pro to be used for pour-over and espresso grinders.

However, I didn’t find the JX version as good for espresso as the JX Pro. In my experience, the JX version worked well for manual brewing, but the JX Pro is what worked best for both espresso and pour-over coffee.

The reason is that the JX Pro offers far more precise fine-tuning compared to its cheaper version. Its micro-adjustment allows it to provide outstanding results of espresso grind. The JX has an adjustable grind, so it isn’t a problem to achieve a fine and coarse grind.

However, the JX-pro is equipped with the same burr as the JX grinder. Moreover, with 40 clicks on the adjustment dial, you can easily dial in your grind to that elusive sweet spot for espresso than JX.

If your primary need is to grind the espresso, I would recommend going for the JX Pro.

The Bad Part of JX and JX Pro?

In my experience, I would say the one common problem with both of the grinders is the static it produces. The first few times I used it, a lot of coffee clung to the burr when I unscrewed it.

That creates a whole mess that takes ages to clean up and wash thoroughly. I would prefer to be doing far more productive things with my mornings than cleaning my coffee grinder (like laying in my bed, for example).

Which One Should You Choose? JX vs JX Pro:

As I’ve said earlier in this review, I don’t particularly think that the standard JX is as suitable for espresso as the JX Pro. That alone makes me lean towards the JX Pro more since I would be comfortable knowing I’m getting the finest espresso for my power start in the morning.

On the other hand, the standard JX is cheaper, lighter, and faster. It all comes down to what you prefer and your primary requirements at the end of the day.

Frequently Asked Questions (FAQs)

1. How to Adjust the Grind Size for JX and JX Pro?

You can adjust the grind size by holding the handle in place and turning a wing-nut type of piece on the bottom of the grinder. You should turn clockwise for more refined and counter-clockwise for a coarser grind.

2. Can You Achieve a Consistent Grind for a Cold Brew With JX and JX Pro Grinder?

Yes! I use pour-over and typically start with it dialed about two complete rotations. But the grind setting can be affected by several things. It’s handy to grind 1-2 beans and examine the coarseness, then make a slight adjustment in that coarse or more refined sort of range.

3. How Often Should I Clean the Grinder?

I think you can clean as often as you want. If it’s taking longer or harder to grind, it’s time to clean it.

  1. Hi, thanks for your great information about JX & JX PRO.
    I just thought I would contact you regarding washing the units with soap and water, correct me if I’m in error but water and especially soap will cause corrosion in these grinders.
