The verdict

The 1Zpresso JX-Pro is a standout manual coffee grinder for enthusiasts who prioritize grind consistency and hand-feel over full-espresso capability. Its dual adjustment system offers remarkable versatility across pour-over, drip, and lighter espresso-adjacent grinds, while the machined aluminum body and smooth crank action justify its higher price tag. It's not the cheapest option on the market, nor the best pure-espresso grinder, but for filter coffee lovers wanting precision and portability, it's an excellent long-term investment.

What owners are saying

Best pour-over grinder I've owned

Switched from a cheaper hand grinder and the difference in consistency is night and day. The external adjustment makes dialing in for different beans quick and repeatable.

Great quality, steep learning curve

Took me a few sessions to understand the click system fully, but once I did, the grind quality for my V60 improved dramatically. Wish it came with a cleaning brush though.

Travel-friendly and precise

I take this on every camping trip. It's compact, grinds fast for a hand grinder, and the burrs produce very little fines. Highly recommend for filter coffee fans.

Excellent but pricey

Performance is fantastic and build quality feels premium, but you do pay for it. Worth it if you're serious about your morning brew ritual.
