1Zpresso K-Plus

What it does well

The grind is even. BrewCoffeeHome calls its consistency "outstanding" and says a medium-coarse setting gives a bright, clean pour-over. Coffee Chronicler found its sifted distribution "almost identical" to the JX-Pro, with cups "more crisp and bright."

The catch cup is the K-Plus's own feature. Coffee Chronicler says the magnetic cup "comes off with a quick pull," and the blind shaker "works splendidly" at breaking up clumps. You can dose straight into a portafilter.

It feels well made. Coffee Chronicler calls it "extremely premium," and says the longer handle helps "crush the beans faster and with less effort." It timed 25 g for pour-over at 35 seconds.

It suits smaller hands. Coffee Chronicler says the body is slimmer than the JX, and BrewCoffeeHome says the narrow body suits people with smaller hands. BrewCoffeeHome timed 20 g for drip at about 25 to 30 seconds.

Where it falls short

Espresso takes patience. Coffee Chronicler calls the 22-micron clicks "a bit more rough" than the JX-Pro or J-Max for electric machines. BrewCoffeeHome says each step will likely shift a shot by 5 to 8 seconds on an unpressurized basket.

Calibration is fiddly. BrewCoffeeHome calls recalibration "quite tricky," needing a few tries to find the zero point. Coffee Chronicler found the instructions "a bit unclear," and warns that tightening the top ring too early can lock the grinder.

There are smaller annoyances. BrewCoffeeHome reports static leaving grounds on the burrs, and a magnetic bin that can come off if held incorrectly. Coffee Chronicler disliked the large logo and the grip band.

Who should buy it, and who shouldn't

Buy a used K-Plus if you brew pour-over, AeroPress or French press most days. The blind shaker is a bonus if you also pull shots on a lever machine. The settings chart on this page covers each method.

Skip it if you dial in espresso daily on an electric machine. Finer clicks will make that easier. Skip it too if you want a warranty, since 1Zpresso no longer sells it new.

How it compares

The 1Zpresso K-Max was its sibling, with the same dial and a slimmer catch cup without the blind shaker. 1Zpresso lists it as discontinued too, so it is also a used-market buy.

For espresso, the 1Zpresso J-Ultra is still sold new. 1Zpresso says its burrs are made for espresso, with 8 microns per click against the K-Plus's 22.

The 1Zpresso JX-Pro has 12.5-micron clicks, which BrewCoffeeHome says make it easier to dial in for espresso. Coffee Chronicler recommends the JX line as the budget option. See JX-Pro vs K-Plus.

The KINGrinder K6 adjusts externally at 16 microns per click, per KINGrinder, for much less money. See K-Plus vs K6. 1Zpresso's K-Ultra, which replaced it, moves 20 microns per click.

Owning it

Clean it dry with a brush and blower, both supplied with the grinder per 1Zpresso. Our guide to cleaning a hand grinder covers the routine.

Re-zero after any strip-down, and do it slowly. Our calibration guide walks through the steps, and helps avoid locking the top ring.

1Zpresso grinders were sold with a one-year limited warranty, which a used unit is unlikely to carry. When buying used, check that the magnets hold the cup firmly and the dial clicks cleanly.
