K Plus 1ZPRESSO

Last updated: October 2, 2026

The 1Zpresso K-Plus is a manual coffee grinder, not an espresso machine. It’s aimed at people who want a capable grinder for espresso and pour-over without adding an electric appliance to the counter. Its main trade-off is simple: it can grind well across brew styles, but you supply the effort—and its price only makes sense if you’ll use that range.

What the K-Plus is

The K-Plus is a hand grinder with a metal body, a folding crank and an external adjustment ring. That external adjustment makes it easier to move between settings than grinders that require disassembly to change the grind. The K series is designed as an all-rounder, covering fine espresso settings as well as coarser brewing methods.

It’s a practical option for someone who owns a manual espresso maker, a prosumer espresso machine, or a pour-over setup and wants one grinder for more than one method. It is not a shortcut to good espresso: the machine, beans, basket and puck preparation still matter. Nor is it a good fit if you want to grind large batches quickly with minimal effort.

Consider the K-Plus if you make one or two drinks at a time, value a compact setup, and regularly switch between espresso and filter coffee. A hand grinder also avoids the motor noise of an electric grinder, which can be welcome in a quiet kitchen or while traveling.

Skip it if you routinely make several drinks back-to-back, share grinding duties with someone who dislikes manual work, or want to fill a hopper and grind on demand. In those cases, an electric grinder is more convenient. If you only brew French press or drip coffee, a less expensive hand grinder may be enough; the K-Plus’s espresso-capable adjustment and broader range are less valuable if you never use them.

K-Plus versus other grinder choices

This is a category comparison, not a claim that every grinder in a row performs the same. Burr design, adjustment range and build quality vary. For a budget hand grinder, compare the adjustment system and whether the manufacturer supports espresso-fine settings before buying. Browse manual espresso grinder options if you want to compare prices and features.

Using it for espresso

Espresso is where a grinder’s small adjustments matter. A shot that runs too fast may need a finer setting; one that chokes the machine may need to be coarser. The K-Plus’s external adjustment is useful for making those changes, particularly if you switch beans or brewing methods. Keep a note of the setting that works for each coffee, since returning to a previous recipe is easier when you have a reference.

Hand grinding espresso takes more work than grinding for a coarser brew. Very light-roasted, dense beans can be especially demanding. If grinding becomes unpleasant, that is a real usability issue, not a failure of technique. For a household making multiple espresso drinks each morning, an electric grinder may be the better purchase even if the hand grinder is capable of producing a suitable grind. Compare electric grinders for espresso if speed and repeated use matter more than portability.

Expect to spend time dialing in a new coffee. A grinder cannot compensate for stale beans, an inconsistent dose or poor puck preparation. If you’re using a pressurized basket or a basic entry-level machine, you may not benefit as much from fine grind adjustments as someone using an unpressurized basket.

Practical drawbacks to know

The biggest drawback is workload. One dose is manageable for many people; grinding for a group can become tedious. The crank also needs room to turn, and the grinder’s capacity means it is better suited to single doses than large batches. If you prefer to prepare a full carafe at once, look at a grinder designed for batch brewing or an electric option instead.

Another possible frustration is switching between brew methods. Although an external adjustment ring helps, moving from espresso to a much coarser setting and back still takes attention. Record settings and purge a small amount after a substantial change if you’re concerned about leftover grounds affecting the next brew. The folding handle and travel-friendly format are useful, but a compact grinder is not automatically the best choice for everyday use if you dislike the physical routine.

When a cheaper grinder is enough

If you make only pour-over, French press or AeroPress, you may not need to pay for an all-rounder built to handle espresso. A simpler hand grinder can be a sensible buy when it offers the grind range you need and you’re comfortable with its adjustment system. Shop budget hand coffee grinders for that use case, but check recent reviews for reports of inconsistent adjustment, loose parts and difficult cleaning.

Choose the K-Plus when you’ll actually use its flexibility. If espresso is your only daily brew and convenience is the priority, put the money toward an electric espresso grinder. If you brew filter coffee occasionally and want a compact manual setup, paying for espresso capability may be unnecessary.

FAQ

Is the 1Zpresso K-Plus an espresso machine?

No. It is a manual grinder. You’ll still need an espresso machine or another brewing device to make coffee.

Can the K-Plus grind for espresso?

Yes, it is designed to cover espresso and coarser brew methods. You’ll still need to dial in each coffee, and manual grinding takes more effort than using an electric grinder.

Is it worth buying if I only make filter coffee?

It can work well, but you may not need its espresso range. A less expensive grinder may be the better value if espresso is not part of your routine.

Should I choose it over an electric grinder?

Choose the K-Plus for compact storage, portability and small batches. Choose electric if you make several drinks often or want to avoid the effort of hand grinding.
