Key Features Review

1. 48mm Stainless Steel Conical Burrs

The 1Zpresso JX Pro manual coffee grinder has an excellent quality, large conical burr. The large size gives a good surface area for hand grinding beans to a high standard.

This is a burr quality similar to those in electronic burr grinders which are at least double the price.

2. Stepped Grind Adjustment Dial with 40 Settings

The adjustable grind selector has a high number of settings that allows you to make very precise adjustments. You can dial in the perfect grind for your espresso or pour over very easily using the knob on top of the grinder.

Psst… If you want even more precision, check out our 1Zpresso J Ultra review

3. Very Fast Grinding

Even at the finest setting, it takes only 30 seconds or so to grind enough beans for your espresso or pour over. Even if it is slightly slower than an electric grinder, this is still much faster than most manual grinders.

4. Ergonomic Handle and Silicone Sleeve

The wooden handle feels nice in your hand, making the JX Pro a dream to use. Plus, the silicone sleeve around the grinder’s body makes it easy to hold steady, even if you have smaller hands (although it’s still not the greatest for little hands).

ease of use icon

Is the 1Zpresso JX Pro Easy to Use?

Being a manual grinder, it takes more work than just pushing a button on an electric grinder. However, many coffee aficionados prefer hand grinding as they have maximum control over the process.

And it couldn’t be easier to use the 1Zpresso JX pro manual coffee grinder:

The JX Pro’s adjustable grind selector is located on the top, allowing you to control how fine a grind you are looking for. You simply fill the upper chamber with your coffee beans and turn the handle to your desired grind size.

The 40-step adjustments allow for very fine tinkering with how coarse you want your coffee grounds to be. Plus, it only takes 30 seconds or so to get the grind you are after (the exact timing depends on how fine you want your grounds).

The only ease of use issue is in precisely measuring your coffee grounds:

If you are looking for a very precise amount of grounds, you need to weigh your coffee beans beforehand to avoid wastage and for the best coffee extraction results. Doing so will require a separate scale.

This makes it a touch more inconvenient than some electric coffee grinders which will either grind a certain weight or for a very precise length of time. This process ensures you get the exact amount that you need.

However, this is a very small complaint in an otherwise very simple-to-use hand grinder.

What are the Different 1Zpresso Model Types?

1Zpresso specializes in manual burr grinders. They have quite a few hand grinders in the range, each highlighting the same great grind quality and innovative design.

Thanks to the variety of models available, you can be specific as to what you are looking for. Doing so will ensure you get your perfect coffee grinder.

Just check the letter following 1Zpresso (e.g. JX Pro) to know which series you are looking at:

Q Series: Fits perfectly into the AeroPress plunger for ease of use. This small manual grinder is, in fact, the smallest model making it very compact and portable. (Examples: 1Zpresso Q2, previously Q1)
J Series: The large capacity offers some of the best value in coffee grinding. Model variations for pour over (JX) and espresso (JE, JE-PlusJX-Pro, and J Ultra). So, deciding between 1Zpresso JX Pro vs J Max vs JX comes down to your preferred coffee style – pour over or espresso.
K Series: External grind adjustment dial with 90 clicks to intuitively and quickly set your ideal grind size. The specialized K Burr is heptagonal shaped, ideal for a variety of brewing methods (Examples: K-Pro, K-Plus, and the latest K-Ultra).
Z-Pro Series: Red Dot Design Award Winner (2018) due to the introduction of the external adjustment ring, just like you would expect on an electric grinder.

Whilst the Q series has the smallest grinders, none are overly bulky. So, no matter which 1Zpresso coffee grinder you opt for, you are guaranteed a high-quality travel hand grinder.

Design and Build Quality Review of the 1Zpresso JX Pro

The JX Pro is relatively big and heavy compared to many portable manual grinders. This is partly due to the heavy-duty 48mm conical burr.

This grinder sizes up at 2.2 inch diameter and 7.1 inches tall. And it weighs 1.7lb. So, while it certainly is compact enough to be taken traveling alongside your portable espresso maker, it is hardly small or light.

The design, however, is sleek and well thought out. The JX-Pro looks good without compromising the ease of use:

Gripping is made easy by the silicone sleeve. Plus, the wooden handle feels nice in your hand while you grind your coffee – no one wants callouses from hand grinding coffee of all things.

The extra weight does add to the feeling of the grinder being hardy and long-lasting. Many people, including us, report using their JX Pro for years with no issues whatsoever. Ultimately a manual grinder has a lot less that can go wrong than an electric one.

The only downside with this grinder – and this is true of all manual grinders – is that if you have any kind of wrist/ elbow/ shoulder issues, arthritis, or general muscle weakness, it can be difficult or painful to use. In this case, we would recommend an electric grinder if at all possible. It’s also not the greatest for little hands – my wife is a petite 5″2 and struggles slightly.

How Consistent are the Grounds from the JX Pro?

It’s all well and good being cheap and portable. But if your device doesn’t produce good grind quality with consistently sized coffee grounds, then it’s all for nothing.

Thankfully the 1Zpresso JX Pro does an excellent job of this – even at the finest and coarsest grind settings. So, it makes a wonderful espresso grinder as well as grinding for French press.

Most grinders will lose consistency at the coarser end of the spectrum. And, while this is still true of the JX Pro, the actual effect on your pour over or French press coffee is undistinguishable which is, ultimately, all that matters.

Having 40 stepped adjustments may not be enough for the serious espresso nut. But it should satisfy most people in producing the exact extraction time you are looking for.

There are also very few “fines” left inside the grinder after use, meaning each cup is made from all fresh grounds for the best taste – no poor quality coffee drinking here. 

cleaning icon

Is it Easy to Clean and Maintain the 1Zpresso JX Pro?

The JX Pro is straightforward to disassemble and reassemble. Plus, it comes with a handy brush which makes it quick and easy to clean all the coffee grounds stuck in the mechanism.

The downside here is you probably need to do this weekly. This ensures you’re always getting fresh grounds and, therefore, better quality coffee. Plus, it prevents any build-up in the grinder itself which would shorten its lifespan.

When you put all the parts back together, the 1Zpresso JX Pro doesn’t require calibrating. So, the whole process will only take around 15 minutes.

Cleaning any grinder is a pain. But, this is actually a bit easier than most electric coffee grinders as it’s so simple to take apart and reassemble.

Just remember not to clean your grinder with water as this will damage the internal mechanisms. A brush and a blow of air is all it takes.

Final Thoughts on our 1Zpresso JX Pro Review

So, what’s the bottom line on the 1Zpresso JX Pro review?

Well, this little hand grinder ticks a lot of boxes: It’s great value, has professional level consistency, and enough grind sizes to offer real precision.

The only real downside to the JX-Pro is that it is a manual coffee grinder. But, that’s kinda the point and if that is what you are looking for then you don’t really need to look any further. Especially as it performs on par with many (more expensive) electric grinders.

You can certainly find cheaper hand grinders, like the JavaPresse Manual. But, you won’t get the same longevity or consistency. Plus, it’s still a lot cheaper than many electric grinders that offer comparable grind consistency.

If you’ve been looking for a quality grinder but have been horrified by the prices then this could be the one for you. There are very few cheap hand grinders out there that perform as well as the JX Pro, saving you from drinking poor quality coffee again.

What to Look for When Buying a Coffee Grinder?

Buying a coffee grinder can be confusing:

There are so many different types of coffee grinder out there from manual to electric, burr or blade. So, how do you know what you want?

Here we will lay out the top things to look for when purchasing a new coffee grinder. This will help you to work out if the 1Zpresso JX Pro is the right fit for you.

Burr or Blade Grinder?

The mechanism that actually grinds your coffee beans is either a burr or a blade. And they produce very different results.

A blade grinder works in the same way as your kitchen blender. In other words, it chops the beans to bits via rotating blades. It won’t produce the best grinding results due to inconsistency but they are a cheaper option. As they need a lot of speed, it’s not possible to get a blade hand coffee grinder. 

On the other hand, burr grinders have two plates (burrs) that rotate, crushing the coffee beans. This process gives the best grinding results with a more uniform grind size and, therefore, a better quality cup of coffee.

It is the spacing between the burrs which determines the grind size.

Within burr grinders, you have a further choice: conical or flat burrs. Conical burr grinders direct the coffee through two cone-like ridges whereas flat burr grinders churn the coffee between two flat plates.

The latter creates greater consistency and gives you more control. However, flat burr grinders are more expensive and less forgiving, so really only seen in most commercial coffee grinders.

The 1Zpresso JX Pro is a conical manual burr grinder, with conical burrs being the top choice of most home baristas.

Grinder Capacity

Every grinder can hold a certain amount of coffee – some are very large, others much smaller. Since it is best to grind the coffee beans directly before using them, you really only need the capacity to match how many cups you regularly make:

If it’s just for you, then a small-capacity grinder will work a treat. Or, if you regularly entertain or have a big coffee drinking family, then you will need something bigger so nobody misses out.

On the 1Zpresso JX Pro, the capacity is 35g. Whilst there are other manual grinders that hold more beans, it is still enough for you and a couple of friends.

Speed

If you’re looking at an electric coffee grinder, the speed will be listed as RPM (revolutions per minute). On manual grinders, like the JX Pro, this isn’t a concern – you dictate the speed.

That said, the smoothness of the mechanism will dictate how easy and fast your hand grinding experience will be. And there is no fault there when it comes to the 1Zpresso JX Pro. Depending on how fine a grind you are after, it will take around 30 seconds.

Size

The physical size of a coffee grinder will vary depending on its capacity and component parts. This will make a difference depending on where you want to use it.

Many manual grinders are portable so you can get your coffee hit on the go. This is one of the benefits outlined in this 1Zpresso JX Pro review.

On the other hand, an electric coffee grinder will need access to electricity. You will also need to dedicate some amount of counter space to it. So, it really comes down to how much spare space you have in your kitchen.
