JX Pro 1Zpresso: A Hand Grinder That Punches Way Above Its Price

I bought the 1Zpresso JX-Pro expecting a decent hand grinder for travel. What I got was a grinder that produces espresso-quality grounds so consistent that I stopped reaching for my electric grinder most mornings. If you're looking at the JX-Pro and wondering whether it lives up to the hype, the short answer is yes, with a few caveats I'll get into below.

The JX-Pro sits in a sweet spot that most hand grinders miss entirely. It handles everything from Turkish fine to French press coarse, and it does so with a stepless adjustment system that gives you more control than grinders costing twice as much. I'll walk you through the build quality, grind performance, how it compares to similar options, and who should (and shouldn't) buy one.

Build Quality and Design

The first thing you notice when you pick up the JX-Pro is the weight. At around 680 grams, it feels like a serious tool, not a toy. The body is stainless steel with a matte finish that resists fingerprints pretty well. The handle is solid, with a wooden knob that stays comfortable even through longer grinding sessions.

Inside, you get 48mm conical steel burrs. That's larger than what you'll find in most hand grinders at this price point. The Comandante C40, for example, also uses 48mm burrs but costs nearly double. Bigger burrs mean faster grinding and more consistent particle size, which translates directly to better-tasting coffee.

The Adjustment System

This is where the JX-Pro really separates itself. It uses a stepless adjustment dial located beneath the burr set. You access it by removing the bottom catch cup and turning the numbered dial. Each full rotation gives you about 40 clicks of adjustment, and the numbers on the dial make it easy to return to your preferred setting.

For espresso, I typically land somewhere around 1.8 to 2.2 rotations from zero. For pour-over, I'm usually at 2.8 to 3.2. The stepless design means you can fine-tune between those clicks, which matters a lot when you're dialing in espresso.

One minor gripe: the adjustment mechanism sits at the bottom of the grinder, so you need to unscrew the catch cup to make changes. It takes about 10 seconds, but it's less convenient than top-adjust grinders like the Comandante.

Grind Performance Across Brew Methods

Espresso

The JX-Pro was specifically designed with espresso in mind, and it shows. The particle distribution at fine settings is tight enough to pull proper shots on machines like the Breville Bambino or Gaggia Classic. I've tested it with a naked portafilter, and the extractions come out even with minimal channeling once you nail the right setting.

Grinding 18 grams for espresso takes roughly 45 to 60 seconds. That's not blazing fast, but your arms won't be sore either.

Pour-Over and Drip

At medium settings, the JX-Pro produces clean, well-defined grounds for V60 and Kalita Wave. The cups I brew with this grinder taste noticeably clearer than what I was getting from my old Hario Skerton. There's more sweetness and less muddiness, which tells me the particle distribution is much more uniform.

French Press

Coarse grinding works fine, though this isn't really the JX-Pro's strength. If you only brew French press, you'd save money with the standard JX model, which is designed for coarser grinds and costs about $30 less.

How It Compares to Other Hand Grinders

The JX-Pro lives in a competitive price range, roughly $159 at the time of writing. Here's how it stacks up against the grinders people usually compare it to.

vs. Comandante C40: The Comandante is the "default" premium hand grinder, and it costs around $280. Honestly, the grind quality between these two is very close. The Comandante has a stepped adjustment that some people prefer for repeatability. The JX-Pro's stepless system gives you finer control. If you're on a budget, the JX-Pro is the smarter buy. If you want the nicer aesthetic and don't mind paying extra, the Comandante is still great.

vs. 1Zpresso K-Plus/K-Max: These are 1Zpresso's own premium models with larger 48mm burrs and external adjustment dials. They grind faster and are more convenient to adjust, but they cost $80 to $100 more. The K-Plus is worth considering if speed matters to you, but the JX-Pro's actual grind quality is comparable.

vs. Timemore C3: The Timemore C3 is much cheaper (around $60 to $70) but uses smaller 38mm burrs and a stepped adjustment. It works okay for pour-over but struggles with espresso fineness. The JX-Pro is a significant step up in every measurable way.

Who Should Buy the JX-Pro

The ideal JX-Pro owner is someone who brews espresso at home and wants consistent results without spending $300 or more on a grinder. It's also perfect for the person who travels and wants to bring their grinder setup on the road. The whole thing fits easily in a backpack.

I'd also recommend it to anyone who's been using a budget hand grinder (Hario, JavaPresse, or similar) and is ready to upgrade. The difference in grind quality and grinding speed is dramatic.

Who Should Skip It

If you grind more than 30 grams at a time regularly, hand grinding gets tedious regardless of how good the grinder is. You'd be better off with an electric option. And if you only brew coarse methods like French press or cold brew, the standard JX or even the Q2 model would save you money without sacrificing the quality you actually need.

Maintenance and Longevity

The JX-Pro is low-maintenance. I blow out the burrs with a rubber air blower after each use and do a deeper cleaning with the included brush every couple of weeks. The burrs are easy to remove for cleaning, and the whole process takes about five minutes.

Steel burrs do eventually wear out, but 1Zpresso sells replacement burr sets. At normal home use (one to two doses per day), the original burrs should last several years before you notice any degradation.

One tip: don't wash the burrs with water. The steel can develop surface rust. A dry brush and occasional rice grinding (just a tablespoon) keeps things clean.

FAQ

Is the 1Zpresso JX-Pro good enough for espresso?

Yes. It's one of the best hand grinders for espresso under $200. The stepless adjustment gives you the fine-tuning control you need, and the 48mm burrs produce a consistent enough grind for proper extraction. I use it with a Breville Bambino Plus and get excellent shots.

What's the difference between the JX-Pro and the regular JX?

The JX-Pro has finer adjustment capability and is designed for espresso-fine grinding. The regular JX is better suited for pour-over and coarser methods. If you never plan to make espresso, save the $30 and get the standard JX.

How long does it take to grind with the JX-Pro?

For a single espresso dose (18g), expect 45 to 60 seconds. For a pour-over dose (25g), it's about 30 to 40 seconds because the coarser setting means less resistance. These times are faster than most hand grinders in the same price range.

Can I use the JX-Pro for Turkish coffee?

You can get the grind fine enough, but it takes a long time and a lot of effort. If Turkish is your primary brew method, look at grinders with smaller burrs designed for ultra-fine work, like the 1Zpresso K-Plus or a dedicated Turkish grinder.

The Bottom Line

The 1Zpresso JX-Pro is the hand grinder I recommend most often to people who want one grinder that does everything well. It's not the cheapest, and it's not the absolute best at any single brew method. But it covers the full range from espresso to French press with grind consistency that used to require spending $250 or more. If you're buying your first serious grinder, or replacing a budget one that's been holding your coffee back, the JX-Pro is the move.
