TIMEMORE Chestnut C3 ESP Manual Coffee Grinder Black — S2C Stainless Conical Burrs, Compact Travel Hand Grinder

The TIMEMORE Chestnut C3 ESP is a compact, all-metal manual coffee grinder engineered with precision S2C stainless-steel conical burrs for consistent grinds from espresso to French press.

This hand grinder blends durable CNC-machined stainless steel construction with a fine-pitch adjustment system to let you dial in grind size with micro-precision. Designed for home baristas and travelers alike, the C3 ESP emphasizes smooth operation, low effort grinding, and easy cleaning while offering a refined, portable profile that fits small hands comfortably.

How does the C3 ESP deliver consistent espresso-level grinds?

The C3 ESP uses TIMEMORE's patented S2C660 stainless steel conical burrs and a double-bearing central axis to reduce wobble and uneven particle sizes. A fine adjustment pitch gives you very small incremental changes, so you can target espresso fines without overshooting.

• 38 mm CNC-machined conical burrs for efficient, uniform grinding
• Double-bearing central axis for stable burr alignment
• Approx. 36 adjustment levels with 0.0233 mm per click precision

Is this grinder easy to turn and comfortable for travel?

Yes—the C3 ESP is designed to minimize effort while maintaining a premium feel. A built-in bearing lets the handle continue rotating briefly after you release it, reducing wrist strain; the folding handle and compact 52 mm body make it travel-friendly and easy to grip.

• Folding handle for compact storage and transport
• 52 mm body diameter suitable for small hands
• Light grinding resistance thanks to optimized burr geometry and bearings

How precise is the grind adjustment and what ranges does it cover?

The adjustment system is geared toward fine control, especially for espresso, while still covering coarser settings for methods like pour-over and French press. Turn clockwise for finer grounds and counterclockwise for coarser results; the fine pitch ensures reproducible settings shot-to-shot.

• Fine ESP pitch with micro increments tuned for espresso
• Adjustable coarse-to-fine range suitable for espresso, drip, and press
• Secure adjustment nut to keep chosen setting stable

What about maintenance and durability?

The C3 ESP's all-metal one-piece enlarged body and CNC burrs are built to last, and the grinder disassembles easily for routine cleaning. Use a brush to remove grounds from the burr and body; periodic deeper cleaning will keep performance consistent over time.

• All-metal construction resists wear and holds calibration
• Simple disassembly for brushing and inspection
• Folding handle and compact parts minimize damage in transit

Who is this for? The TIMEMORE Chestnut C3 ESP is aimed at espresso lovers who want precise manual control, travelers who need a robust portable grinder, and home baristas who value build quality and repeatable settings. If you grind frequently for fine espresso or want a compact, durable hand grinder that covers the full extraction spectrum, the C3 ESP balances precision, ergonomics, and portability without relying on electricity.
