1Zpresso JX Grinder: The Hand Grinder That Made Me Ditch My Electric

The 1Zpresso JX is a manual hand grinder that costs around $70 to $90 and punches well above its price tag. If you're considering a hand grinder for pour-over, AeroPress, or other filter brewing methods, the JX is one of the most recommended grinders in the specialty coffee community, and that reputation is well-earned. I switched to the JX from an electric grinder and actually preferred it for my morning routine.

I'll cover the grind quality, the build, the daily workflow, and how the JX compares to its siblings (the JX-Pro and J-Max) and other popular hand grinders. If you're wondering which JX model to buy or whether a hand grinder is right for you, this should clear things up.

Grind Quality

The JX uses a 48mm stainless steel conical burr set, which is large for a hand grinder. Most hand grinders in this price range use 38mm burrs. The larger burr size means fewer rotations per gram of coffee and a more uniform particle distribution.

For filter coffee, the JX is outstanding. V60 pour-overs come out clean, sweet, and balanced. AeroPress brews have a clarity that I didn't consistently achieve with my old Baratza Encore. The particle uniformity at medium and medium-coarse settings is genuinely impressive for a $80 grinder. I've done side-by-side V60 brews comparing the JX to a Comandante C40 (which costs 3x more), and the difference in the cup was subtle. The Comandante was slightly sweeter, but not $170 sweeter.

French press grinds are good too. The JX produces a consistent coarse grind with minimal fines, which means less sludge in the bottom of your cup. I do French press twice a week, and the JX handles it without issues.

What About Espresso?

Here's the important distinction: the standard JX is designed for filter coffee. It does not have the adjustment precision for espresso. The click settings are too coarse for fine-tuning espresso extraction. If you want espresso from a 1Zpresso grinder, you need the JX-Pro (which has finer click increments) or the J-Max (which is built specifically for espresso).

I tried grinding espresso-fine on the standard JX, and while the burrs can physically produce a fine enough grind, the adjustment jumps between clicks are too large. One click too coarse means a fast, sour shot. One click too fine means a choked, bitter shot. The JX-Pro solves this with roughly twice as many clicks in the same range.

Build Quality

1Zpresso builds their grinders in Taiwan (not mainland China), and the quality control shows. The JX body is machined aluminum with a matte black finish. The bearing system is smooth, with almost no wobble in the crank handle. The outer burr housing is stainless steel, and everything fits together with tight tolerances.

Holding the JX, it feels like a precision tool. There's no flex, no rattle, and the adjustment clicks are distinct and satisfying. I've dropped mine twice (once on tile floor), and it survived both times without any damage to the burrs or alignment. The included carrying case adds protection for travel.

At about 12 ounces, the JX is light enough to pack in a bag but heavy enough to feel substantial in your hand during grinding.

The Crank Handle

The folding crank handle is one of the JX's best design features. It folds flat against the body for storage, and when extended, it provides good leverage. The bearing at the top is smooth and consistent. I've never felt grinding fatigue with the JX, even when doing 30+ gram doses for a large Chemex brew.

The handle length gives you a comfortable rotation arc. Each full turn of the handle processes about 0.8 to 1.0 grams, so an 18-gram dose takes roughly 20 full rotations. At a comfortable pace, that's about 25 to 30 seconds. Fast and focused, I can do it in 20 seconds.

Daily Workflow

My morning routine with the JX takes under two minutes from start to cup. Here's what it looks like:

  1. Weigh 15 grams of beans (I do single-cup V60).
  2. Drop beans into the JX grinder top.
  3. Set the grind at 24 clicks from zero (my V60 setting).
  4. Grind for about 25 seconds.
  5. Dump grounds into the V60 filter.
  6. Brew.

The manual process is meditative in a way I didn't expect. I've come to enjoy the few seconds of hand grinding as part of the morning ritual. It's quiet (no motor noise to wake anyone up), satisfying, and produces better-tasting coffee than the electric grinder it replaced.

Retention and Cleanup

Retention is essentially zero. Because the burrs are oriented vertically and gravity pulls grounds straight down into the catch container, almost nothing stays behind. I measured retention at 0.0 to 0.1 grams, which is as close to zero as you'll find on any grinder. This makes the JX perfect for people who switch between different beans frequently.

Cleaning is simple. I brush the burrs with the included brush every week or two. A deeper clean involves unscrewing the bottom adjustment wheel and removing the inner burr for a thorough brush-out. This takes about 3 minutes and keeps the grinder performing like new.

JX vs. JX-Pro vs. J-Max

1Zpresso's naming gets confusing, so let me clarify the differences:

JX (standard): 48mm burrs, designed for filter coffee. About 20 adjustment clicks per rotation. Price: $70 to $90. Best for: pour-over, AeroPress, French press, drip.

JX-Pro: Same 48mm burrs but with a finer adjustment mechanism (about 40 clicks per rotation). This gives you the precision needed for espresso while still handling filter coffee. Price: $110 to $140. Best for: people who do both espresso and filter.

J-Max: 48mm burrs with the finest adjustment available (about 90 clicks per rotation). Built for serious espresso single-dosing. The grind quality at fine settings is exceptional. Price: $170 to $200. Best for: dedicated espresso users.

If you only do filter coffee, get the standard JX and save the money. If you want one grinder for everything, the JX-Pro is the sweet spot. If espresso is your obsession, the J-Max is worth the premium.

JX vs. Other Hand Grinders

Against the Comandante C40 ($250): The Comandante is the darling of the hand grinder world, and for good reason. Its grind quality at medium settings is slightly better than the JX. But the JX gets you about 90% of the Comandante's quality for about 35% of the price. Unless you're a competitive brewer or have a refined palate, the JX is the better value.

Against the Timemore C2 ($60): The C2 is cheaper and produces decent grinds for its price. The JX is better built, has larger burrs (48mm vs. 38mm), and produces noticeably more uniform grinds. If your budget allows the extra $20 to $30, the JX is the better buy.

Against the Hario Skerton ($40): The Skerton is an entry-level hand grinder with ceramic burrs. The JX's steel burrs produce dramatically better grind quality, and the build is in a different league. The Skerton has its place as a $40 camping grinder, but for daily use, the JX is worth every extra dollar.

Who the JX Is For

The 1Zpresso JX is ideal for:

  • Filter coffee enthusiasts who want outstanding grind quality without spending $200+
  • Travelers who need a compact, portable grinder for hotel rooms and camping
  • Morning brewers who enjoy a quiet, meditative grinding ritual
  • Apartment dwellers who can't run a loud electric grinder at 6 AM
  • Budget-conscious upgraders who want specialty-quality grinds at an entry-level price

The JX is not ideal for espresso users (get the JX-Pro instead) or people who grind large batches (40+ grams). Hand grinding gets tiring past about 30 grams, and electric grinders are more practical for batch brewing.

FAQ

How many clicks for V60 on the 1Zpresso JX?

I use 22 to 26 clicks from fully closed (zero), depending on the bean. Start at 24 and adjust based on brew time. If your 15g dose V60 brews in under 2:30, go finer. Over 3:30, go coarser.

Can I take the 1Zpresso JX on a plane?

Yes. Hand grinders are TSA-approved in carry-on luggage. I've flown with mine several times without any issues. The folding handle and carrying case make it travel-ready.

How often should I replace the burrs?

1Zpresso's steel burrs last a long time. At typical home use (15 to 30 grams per day), expect several years before the burrs show wear. Replacement burr sets are available directly from 1Zpresso for about $25 to $35.

Is hand grinding really faster than electric?

Total time is about the same. An electric grinder does 18 grams in 8 to 12 seconds, but you also have to deal with retention, purging, and cleanup. The JX does the same dose in 25 seconds with zero retention and almost no cleanup. The practical difference is minimal.

My Recommendation

The 1Zpresso JX is the best value in coffee grinding right now, period. For under $100, you get grind quality that rivals $200+ electric grinders and $250 hand grinders. If filter coffee is your focus, buy the JX, set it to your preferred click count, and enjoy the best coffee of your life every morning. It's the grinder I recommend to every friend who asks me how to make better coffee at home. See our top coffee grinder picks for the full lineup of options across all categories and price points.
