In brief

The C3 ESP is the espresso-oriented version of Timemore's Chestnut C3 hand grinder. Timemore lists 38 mm S2C steel burrs, 30 clicks per circle, and 0.0233 mm per click, in an all-metal aluminum body with dual bearings.

Its sibling, the C3S, has a coarser dial for filter coffee. Brew Coffee at Home puts the C3 ESP at about 23 microns a step against about 83 for the C3S, and says the ESP costs a little more for finer control.

Independent reviews of the ESP itself are limited; the best-known C3 review covers the standard version. Most of what follows is Timemore's page, one review of the ESP and the C3S, and what Home Coffee Expert reports about the standard C3.

What it does well

  • Brew Coffee at Home found espresso with rich texture and an excellent body
  • Timemore lists an all-metal aluminum body with dual bearings and no internal plastic parts
  • Brew Coffee at Home calls build quality excellent for the price and compares it to mid-range grinders
  • Settings are printed on the dial, per Brew Coffee at Home, which removes guesswork

Where it falls short

  • Brew Coffee at Home says 23-micron steps do not give enough control for a perfect shot
  • Brew Coffee at Home reports about 1 minute 12 seconds to grind 17 g of espresso
  • Home Coffee Expert says the standard C3 is poor for espresso, with only one workable setting
  • Home Coffee Expert notes the 25 g capacity is small

What it does well

It makes espresso at a low price. Brew Coffee at Home found the coffee "rich in texture and with an excellent body," and recommends the ESP for espresso and the C3S for filter. Timemore lists the grinder as designed for espresso.

The build is the other selling point. Timemore says the body is aluminum alloy "devoid of any plastic components inside." Brew Coffee at Home calls build quality "excellent" for the price and sturdier and quieter thanks to the metal and silicone base. Note that Home Coffee Expert describes the standard C3 as having plastic stabilization parts, so the all-metal claim applies to the ESP.

Filter works too. Home Coffee Expert's review of the standard C3, with the same 38 mm burr design, praises strong consistency, especially at coarser settings, and rates it 8 out of 10, best suited to drip and French press. That reviewer did not test the ESP, so read it as a guide to the burr, not the dial.

Settings printed on the dial, a cleaning brush in the box and a 25 g capacity make daily use simple, per Brew Coffee at Home and Timemore.

Where it falls short

Espresso control is limited. Brew Coffee at Home says 23-micron steps "doesn't quite offer enough control to perfect a shot" compared with higher-end manual grinders, and the reviewer sometimes adjusted the dose instead. Home Coffee Expert found the standard C3 gave a workable shot at only one setting.

It is slow for espresso. Brew Coffee at Home reports about 1 minute 12 seconds for 17 g, which is a real workout for a morning shot.

The adjustment is less convenient. Brew Coffee at Home says changing the grind through the dial is less convenient than an external dial, and that the materials are less robust than the Chestnut X.

Capacity is small. Timemore lists 25 g, and Home Coffee Expert calls the standard C3's small capacity a con. That is enough for one or two cups, not a batch.

Who should buy it, and who shouldn't

Buy it if you want one inexpensive hand grinder for espresso, AeroPress and pour-over, and you accept that espresso dialing is coarse.

Skip it if you chase precise shots, or want to switch between methods quickly. Skip it too if you grind large doses every morning.

How it compares

The Timemore Chestnut C3 ESP Pro is the same grinder with a foldable crank, which suits travel.

The 1Zpresso J-Ultra has a burr built for espresso with finer steps; Home Coffee Expert says the J-Ultra performs better than the C3 but costs about twice as much. See the J-Ultra guide.

The KINGrinder K6 has an external dial. Brew Coffee at Home says adjusting through the C3 ESP's dial is less convenient than an external dial, so the K6 is the pick if you change settings often.

Owning it

Do not wash it. Timemore says to clean it with the supplied brush and not with water. Our guide to cleaning a hand grinder covers the routine, and the dial-in guide explains how to find your starting point.

Timemore's page does not state warranty terms, so check with the seller. It also showed some colors sold out when this page was checked.
