TIMEMORE Chestnut Grinders: C3S, C5, C5 Pro, G1 & S3 ESP

TIMEMORE's Chestnut line is one of the most popular families of manual coffee grinders, and one of the most confusing to shop. Several models look alike, and the differences that matter are in the burrs, the adjustment dial and the design.

This guide skips the spec-sheet overload. Start with how you brew, then match it to a grinder.

Step 1: Start with how you brew

Pour-over, AeroPress, French press: You don't need ultra-fine adjustment. Prioritize consistency, feel and ease of use.
Moka pot: It sits between filter and espresso. Most quality hand grinders can reach it, so you don't need an espresso-specific model unless you also pull shots.
Espresso: You need small, repeatable adjustment steps. This is where the ESP models earn their place.
A bit of everything: Choose a grinder with a numbered dial so you can return to a setting you liked.

The quick comparison

Model	Best for	Standout feature
C3S	Compact everyday filter brewing	38 mm S2C660 burrs, 525 g, 25 g capacity
C5 (previous generation)	Pour-over, AeroPress, French press	Stepped dial focused on flavor clarity
C5 ESP (previous generation)	Filter brewing plus espresso	Finer adjustment thread for micro-adjustments
C5 Pro	Mostly pour-over, occasional espresso	42 mm burrs, 48 clicks per revolution
G1	Filter brewing, with standout looks	Walnut catch cup and 38 mm conical burrs
S3 ESP	Espresso and frequent dialing in	External adjustment ring, 0.015 mm adjustment scale

C3S: compact and no-fuss

The C3S is the most compact grinder in the lineup. Its aluminum alloy body measures about 147 × 52 mm and weighs 525 g, and it holds up to 25 g of beans. It uses 38 mm SUS420 stainless steel S2C660 burrs and comes in black or white.

It's a good fit for daily pour-over and other filter brewing, especially if you want a light grinder that is easy to pack and handle.

C5 vs. C5 ESP: same family, different dial

The C5 and C5 ESP are the previous generation of the C5 line. They remain a solid choice, but the newer C5 Pro below has larger burrs and a finer numeric dial.

The standard C5 is tuned for filter-style brewing such as pour-over, AeroPress and French press. Its point-to-point dial makes it easy to move between coarse and medium-fine.

The C5 ESP is built for people who also want to pull espresso. Its finer adjustment thread gives the small steps espresso dialing requires, and it still works for filter brewing.

If you only brew filter coffee, the standard C5 is enough. If you make espresso regularly, choose the ESP version.

C5 Pro: a pour-over grinder that can do the occasional shot

The C5 Pro is the upgrade in the C-series, with larger 42 mm seven-blade burrs. TIMEMORE says it grinds 5% more consistently than the C3S and has a 16.23% longer grinding path.

For daily use, the practical gains are:

Numeric dial: 48 clicks per revolution at 0.031 mm per click, so you can write down a setting and repeat it.
Grippy, slim body: Engraved grooves and a silicone base keep it steady on the counter.
Capacity: A 30 g bean chamber and a 25 g catch cup, suited to smaller daily brews.
Folding handle: Easier to store and travel with.

Its home territory is pour-over, with room for the occasional espresso. If espresso is your daily drink, look at an ESP model instead.

G1: the one that looks as good as it grinds

The G1 is the design piece of the Chestnut family. A black aluminum body sits on a black walnut base, with a matching walnut knob that attaches magnetically to the metal handle.

Inside, it uses 38 mm conical HRC58 stainless steel burrs and a stepped, point-to-point dial. It holds 25 to 30 g of beans, weighs roughly 560 to 570 g and comes with a cloth carrying bag.

The G1 suits filter brewing like pour-over, French press and AeroPress best. If you want a hand grinder that looks at home on a kitchen counter, this is the one.

S3 ESP: for people who dial in often

The S3 ESP combines fine adjustment with the convenience of an external adjustment ring.

External adjustment ring: TIMEMORE's first, for quick changes without opening the grinder.
0.015 mm adjustment scale: Fine enough for dialing in espresso, with room to reach coarser filter settings.
Foldable handle: Easier to store and travel with.

If you pull espresso regularly, or you simply enjoy fine-tuning a recipe, this is a strong choice.

So which should you choose?

Mostly pour-over, with an occasional espresso? Choose the C5 Pro.
Brewing filter coffee and want something compact? The C3S fits.
Pour-over and AeroPress, with a simple stepped dial? Choose the C5 (previous generation).
Espresso most days? Choose the C5 ESP or the S3 ESP.
Want a grinder that doubles as counter décor? Choose the G1.
