Good espresso grinders are expensive, loud and big. A good hand grinder is none of those. For one or two shots a day, it can grind as well as an electric grinder that costs twice as much. The price you pay is half a minute of cranking.
But not every good hand grinder is a good espresso grinder. The spec that decides it isn’t the burr size. It’s how far the burrs move with each click of the dial.
Why Step Size Decides Everything
Espresso is touchy. A small change in grind moves the shot time by several seconds. If one click on your grinder is too big a jump, you’ll find one setting that runs too fast and the next one that chokes the machine, with nothing in between. Filter coffee doesn’t care much. Espresso does.
Look for steps of about 20 microns or smaller. Under 10 is very comfortable. Over 30 makes espresso hard work. For the reasons espresso is this fussy, see our espresso grinder guide.
Built for Espresso
1Zpresso J-Ultra. The current favourite for espresso. 48 mm burrs, 8 microns per click, an external numbered dial and quick grinding for its size. It replaced the J-Max, which you’ll still see around. If you’re moving a recipe across, J-Max clicks times 1.1 gets you close on the J-Ultra.
Kinu M47. A heavy, all-metal grinder with 47 mm burrs, made for espresso first. The Simplicity model is stepless, around 10 microns per mark, so you can set it anywhere. It’s less handy for pour-over.
All-Rounders That Can Do Espresso
Kingrinder K6. The value pick. 48 mm steel burrs, 16 microns per click, an external dial, and a price around half the J-Ultra’s. Espresso is workable, filter is good.
1Zpresso K-Ultra. A superb filter grinder at 20 microns per click. It can make espresso, but if espresso is your main drink, the J-Ultra is the better buy.
Timemore Chestnut C3 ESP Pro. The cheapest grinder here that’s set up for espresso, at about 23 microns per click. The 38 mm burrs are small, so it’s slow. One review timed over a minute for a 17 g dose. Fine if you make one shot a day.
Great Grinders, Not for Espresso
Comandante C40 MK4. The benchmark for filter coffee. For espresso, its steps are big, about 30 microns, and the espresso range is only a handful of clicks. The Red Clix axle halves the step and makes it usable, but you’re paying extra to fix something the J-Ultra does out of the box.
The Timemore C3S has the same burr as the C3 ESP with much bigger steps, around 83 microns. It’s a filter grinder. Don’t buy it for espresso.
Pairing It
A hand grinder makes the most sense next to a manual lever espresso maker, where neither needs a socket, or next to a compact machine like the De’Longhi Dedica. Weigh the beans first on an espresso scale, because hand grinders hold only so much. If you’re making four milk drinks every morning, buy an electric grinder. Your wrist will thank you.
Small clicks. That’s the whole test.
