JX Pro: The Hand Grinder That Changed How I Brew Espresso

The 1Zpresso JX Pro is one of the best manual coffee grinders you can buy for espresso, and it does a surprisingly good job with pour over and French press too. If you're considering one, the short answer is yes, it's worth the money, especially if you want espresso-capable grinding without spending $300+ on an electric burr grinder.

I've been using a JX Pro for over a year now, and it replaced a Baratza Encore that I'd used for three years before that. The difference in grind quality was immediately obvious, particularly for espresso. In this piece, I'll walk you through what makes the JX Pro stand out, where it falls short, and who should actually buy one versus looking at other options.

Build Quality and First Impressions

The JX Pro feels like a serious tool the moment you pick it up. It weighs about 680 grams (roughly 1.5 pounds) and the body is made from aluminum alloy with a stainless steel burr set. There's no plastic creaking or wobble when you grip it.

The adjustment dial sits on top, under the handle. It uses a numbered system with clicks that correspond to different grind sizes. Each full rotation has 10 numbered positions, and each number has 3 clicks between them, giving you 30 clicks per rotation and roughly 90 total settings from Turkish fine to French press coarse.

What's in the Box

You get the grinder itself, a carrying case (more on that later), a cleaning brush, and a small card that maps click settings to brew methods. The carrying case is actually usable, not just packaging fluff. It's a hard EVA case that fits the grinder with the handle detached. I've taken mine camping twice and it survived both trips without a scratch.

The handle attaches magnetically and locks with a simple twist. It's a small detail, but it makes storage and travel much easier compared to grinders with fixed handles.

Grind Quality and Consistency

This is where the JX Pro earns its reputation. The 48mm stainless steel burrs produce remarkably uniform particles, especially in the espresso range.

I've compared it side-by-side with my friend's Niche Zero (a $700 electric grinder) using a Kruve sifter. The JX Pro wasn't identical, but it was closer than any hand grinder at this price point has a right to be. For pour over at around 24 clicks, the consistency was nearly indistinguishable. For espresso at 12-15 clicks, the Niche still won, but the gap was smaller than I expected.

Espresso Performance

At settings between 10 and 18 clicks (depending on your beans and machine), the JX Pro dials in well for espresso. I typically land around 13-14 clicks for a 1:2 ratio in 25-30 seconds on a Breville Bambino.

One thing worth noting: single-dosing is where this grinder really shines. You put in exactly the dose you want (I use 18 grams), grind it all, and there's almost zero retention. I've measured less than 0.1 grams stuck in the burrs after grinding. That means no wasted coffee and no stale grounds mixing into your next shot.

Filter Coffee Performance

For pour over, the JX Pro works great at 20-27 clicks depending on your method. V60 sits around 22-24 for me, Chemex around 25-27. French press works at 30+ clicks, though honestly, if you're only brewing French press, you don't need this grinder. Something like the standard 1Zpresso JX (non-Pro) or the Timemore C2 would save you money.

The Grinding Experience

Let's talk about the part people worry about most: the actual grinding.

For a 15-gram espresso dose, it takes me about 45-55 seconds of continuous cranking. Pour over at coarser settings is faster, around 30-35 seconds for 20 grams. It's a workout in the sense that you're doing something physical, but it's not difficult. The bearings are smooth and the handle has enough length for good leverage.

The noise level is surprisingly low. My electric grinder used to wake up my wife when I ground coffee at 5:30 AM. The JX Pro makes a quiet crunching sound that doesn't carry through walls. That alone was worth the switch for me.

Adjustment Between Brew Methods

If you switch between espresso and pour over regularly, you'll want to write down your settings. I keep a sticky note on my espresso machine: "Ethiopian natural: 13 clicks. Colombian washed: 14 clicks. Pour over V60: 23 clicks."

Adjusting between settings takes about 10 seconds. You pop the top dial, count clicks, and you're ready. It's not as fast as an electric grinder with a digital display, but it's far from inconvenient.

Who Should Buy the JX Pro (And Who Shouldn't)

The JX Pro makes the most sense for a few specific types of coffee drinkers.

Buy it if: You want espresso-quality grinding without the price tag of a good electric grinder. You're a single-dose brewer. You value quiet morning grinding. You travel and want to bring good coffee with you. Or you're stepping up from a blade grinder or entry-level burr grinder and want something that will last years.

Skip it if: You grind for more than two people daily (the hand grinding adds up). You only brew French press or cold brew (you're overpaying for precision you don't need). Or you simply don't want the manual effort, in which case check out our best coffee grinder roundup for electric alternatives.

The JX Pro sits at around $159, which sounds like a lot for a hand grinder until you compare it to electric grinders with similar grind quality. The Baratza Sette 270 ($400), Eureka Mignon ($300+), and Niche Zero ($700) are all in that conversation. From a pure grind-quality-per-dollar perspective, the JX Pro is hard to beat.

How It Compares to Other Hand Grinders

The JX Pro's main competitors are the Comandante C40 ($250+), the Kinu M47 ($200+), and 1Zpresso's own Q2 and K series grinders.

Against the Comandante, the JX Pro offers more espresso-focused adjustment steps at a lower price. The Comandante has a slight edge in pour over consistency according to most side-by-side tests, but the difference is marginal. I'd pick the JX Pro for espresso-heavy use and the Comandante for filter-only brewing.

The Kinu M47 is built like a tank and has excellent grind quality, but it's heavier and more expensive. If money isn't a concern and you want the premium feel, the Kinu is worth considering.

For a budget-friendly alternative, you might also look at options in our top coffee grinder list. Some manual grinders under $100 perform well for filter brewing, though they fall short at espresso settings.

FAQ

Is the JX Pro good enough for espresso?

Yes, and it's one of the best hand grinders for espresso under $200. The 48mm burrs and fine adjustment steps (30 clicks per rotation) give you the precision needed to dial in shots. I pull espresso with mine daily and get consistent 25-28 second extractions.

How long does the JX Pro last?

The stainless steel burrs are rated for years of daily home use before needing replacement. I've had mine for over a year with daily grinding and see no signs of wear. 1Zpresso also sells replacement burr sets if you ever need them.

Can I use the JX Pro for Turkish coffee?

You can grind fine enough for Turkish coffee at the lowest settings (1-5 clicks), but the process is slow. It takes about 2 minutes to grind 10 grams at Turkish fineness. It works, but if Turkish is your primary brew method, a dedicated Turkish grinder would be more practical.

JX Pro vs JX-S: what's the difference?

The JX-S has a different burr geometry optimized for filter brewing with fewer fine-tuning steps in the espresso range. The JX Pro has more clicks per rotation in the fine range, making it better for espresso. If you never brew espresso, the JX-S saves you about $20 and performs slightly better for pour over.

The Bottom Line

The 1Zpresso JX Pro does one thing exceptionally well: it produces espresso-quality grinds in a quiet, portable, and affordable package. It's not the fastest option, and it requires physical effort every morning. But if you're willing to spend 60 seconds cranking a handle, the coffee it produces punches well above its price point. Write down your click settings for each bean, keep the burrs clean with the included brush, and this grinder will serve you well for years.
