PRODUCT OVERVIEW

What it is and how it works

The Chestnut C3S Pro is a hand-operated grinder with an aluminum-alloy body, 38 mm S2C660 stainless-steel conical burrs, threaded catch cup, and folding handle. TIMEMORE lists a 20 g capacity for C3S Pro.

TIMEMORE’s current C3-series page describes the broader family’s adjustment and grind range. Keep model names distinct: C3S Pro is not the separately named C3 ESP Pro, which TIMEMORE identifies as having finer espresso adjustment control.

CHECK BEFORE YOU BUY

Compatibility at a glance

This standalone grinder produces loose grounds. A machine can use those grounds only when its manufacturer supports pre-ground coffee; the grinder does not attach to a machine.

Brewers that accept loose grounds

Grind beans for pour-over, French press, drip, or espresso workflows as appropriate to your recipe. For any specific brewer, follow its manual for grind and dose requirements.

Espresso setting expectations

TIMEMORE lists espresso through French press for the C3 series and describes finer dialing control for the ESP and ESP Pro models. Do not assume the C3S Pro has the finer adjustment system of a C3 ESP Pro.

Built-in grinder and capsule machines

The C3S Pro does not connect to a machine. Use its grounds in a bean-to-cup or capsule machine only if the manual for that exact model has a manufacturer-approved ground-coffee bypass or chute.

PRACTICAL GUIDE

Choose the correct model and dose

Weigh a dose that fits within the manufacturer-listed 20 g capacity, then secure the catch cup before grinding.
Use the grind adjustment as a starting point and make small changes based on the brewer and coffee. The C3S Pro is the standard C3S Pro model; the ESP Pro version is a separate model with finer espresso control.
For disassembly and cleaning, follow the C3 grinder instructions in TIMEMORE’s official download center. Keep the grinder separate from powered coffee-machine internals.

BEFORE ORDERING

A quick fit and care checklist

Confirm the product name is Chestnut C3S Pro and not C3S, C3 ESP Pro, or another C-series model.
Plan around a 20 g dose capacity; the C3S Max is a different, larger model.
Check that your machine accepts loose ground coffee if you plan to use it with a capsule or automatic brewer.
