The short answer

Choose the Timemore C3 for a compact, light first hand grinder for filter coffee. Choose a 1Zpresso for espresso: the K-Ultra if you switch methods daily, the JX-Pro if you brew espresso first. The 1Zpresso grinders use larger 48 mm burrs, and the JX-Pro the finest steps per click.

1. Choose this for a compact first hand grinder

Timemore Chestnut C3

Manual tier · The budget hand grinder that made stainless conical burrs cheap.

38 mm S2C steel burrs in a light aluminum body.

The Chestnut C3 uses S2C steel burrs in a 38 mm size, taken from Timemore's more expensive Chestnut X, in an aluminum alloy body with a textured grip.

Timemore describes it as suited to everything from espresso to pour-over and French press, with roughly 36 settings at about 23 microns per click.

It is light and compact, which makes it an easy travel grinder.

Its smaller burrs are the trade: at 38 mm against 48 mm, it has less cutting surface than the 1Zpresso grinders here.

Specification

Burrs
38 mm S2C stainless conical, 55-58 HRC
Settings
Roughly 36, about 0.0233 mm per click
Capacity
25 g
Weight
About 530 g
Build
Aluminum body, double-bearing axis, no plastic internals

What it does well

  • Filter-grade grind quality at a genuinely low price
  • Metal internals and double bearings, not a toy
  • Small and light enough to travel with

Where it gives ground

  • 38 mm burrs make an espresso dose slow work
  • Espresso resolution is marginal
  • 25 g capacity limits you to one brew at a time

Skip it if

Skip it if espresso is your main drink. A 48 mm grinder with published fine steps suits espresso dialing better.

2. Choose this for espresso and filter

1Zpresso K-Ultra

Manual tier · A 48 mm hand grinder with external adjustment, built as an all-rounder.

48 mm heptagonal burrs and an external 100-click ring.

The K-Ultra uses a 48 mm heptagonal conical stainless burr with an external ring at 100 clicks per rotation, listed at 20 microns per click. It weighs 685 g.

One full turn moves the burrs about 2,000 microns, so moving between espresso and filter settings is quick.

Its magnetic catch cup holds 35 to 40 g.

Specification

Adjustment
External ring, 100 clicks per rotation
Resolution

Weight

Catch cup
Magnetic, 35-40 g

What it does well

  • External adjustment - you change grind without opening anything
  • Seven cutting edges rather than six speeds the grind up noticeably
  • Genuinely good across espresso, filter and French press

Where it gives ground

  • 20 microns per click is coarser than the JX-Pro espresso resolution
  • Heavier than a travel grinder should be
  • Premium price for a hand grinder

Skip it if

Skip it if you only brew filter and want the lightest grinder to carry. The C3 is smaller.

3. Choose this for espresso steps

1Zpresso JX-Pro

Manual tier · A 48 mm hand grinder with internal adjustment fine enough for espresso.

48 mm burrs at 12.5 microns per click.

The JX-Pro uses a 48 mm steel conical burr with internal adjustment at 40 clicks per rotation, listed at 12.5 microns per click - the finest published step here.

Fine steps are what espresso dialing needs.

Internal adjustment makes switching methods slower than an external ring.

For espresso-only brewers, that is a small price for the resolution.

Specification

Burrs
48 mm steel conical
Adjustment
Internal, 40 clicks per rotation
Resolution
12.5 microns per click

What it does well

  • 12.5 microns per click is finer resolution than most electric grinders
  • 48 mm burrs make short work of an espresso dose
  • No power, no static, nothing to break

Where it gives ground

  • The adjustment dial sits inside the hopper - you lift the lid to change it
  • Grinding espresso by hand every morning gets old for some people
  • No dosing aid: you weigh in, you weigh out

Skip it if

Skip it if you switch methods every day. The K-Ultra's external ring is quicker.

Burr size and what it means

Larger burrs have more cutting surface, which is one reason the 48 mm grinders are favored for espresso. The C3's 38 mm burrs are well suited to filter brewing and keep the grinder small and light.

Microns per click make adjustment easy to reason about - about 23 on the C3, 20 on the K-Ultra and 12.5 on the JX-Pro - see 1Zpresso vs KINGrinder K6 for another 48 mm comparison.

Questions people actually ask

Is 1Zpresso better than Timemore?

What burrs does the Timemore C3 use?

38 mm S2C steel burrs, which Timemore took from its more expensive Chestnut X.

Which 1Zpresso is best for espresso?

The JX-Pro has the finest published step at 12.5 microns per click. The K-Ultra suits people who switch between espresso and filter.

Can the Timemore C3 grind for espresso?

Timemore describes it as covering espresso to French press. A 48 mm grinder with finer steps, like the JX-Pro, is the stronger espresso choice.
