TIMEMORE Chestnut C3 Manual Coffee Grinder - Precise 36-Step

In this review the TIMEMORE Chestnut C3 manual coffee grinder is evaluated for home brewers and travelers who want a compact, well-engineered hand grinder. The bottom line: it delivers consistent, uniform grinds thanks to its CNC stainless steel conical burr and double bearing positioning, making it a strong choice for French press and other coarse to medium methods. The grinder feels solid in the hand and offers fine control with about 36 adjustment steps, so precision and build quality are the main reasons to buy.

Key Features

• CNC Stainless Steel Conical Burr: The S2C660 conical burr is CNC machined for uniform particle size and efficient grinding of coffee beans.
• Double Bearing Positioning: Central axis double bearing keeps the burrs aligned for consistent grind distribution and repeatable results.
• 36-Step Adjustment: The adjustment nut offers roughly 36 steps so users can dial grind size from fine to coarse with clear clockwise/fine and anti-clockwise/coarse directions.
• Labor-Saving Handle: A built-in bearing makes the handle spin smoothly and reduces effort so grinding feels lighter even during longer sessions.
• Compact, Portable Design: At about 700g and a 52 mm body width, it balances a feeling of quality with portability for travel or outdoor use.
• Easy to Clean: The grinder disassembles for simple brushing and maintenance so it stays performing well over time.

Who It's For

The Chestnut C3 is aimed at coffee enthusiasts who value mechanical precision and consistent grind quality for methods like French press, pour-over and drip where uniformity matters. Its compact size and moderate weight make it useful for campers and travelers who want a premium hand grinder rather than a cheap plastic model.

Users who need to grind large daily batches or who prefer automated electric grinders should look elsewhere, because capacity is limited (around 20-25 g of beans) and manual operation is slower than electric options. Those who want ultra-fine espresso grind at high throughput may also prefer a dedicated electric grinder.

Pros & Cons

Pros

• Excellent grind consistency from the 38 mm CNC conical burr and double bearing alignment.
• Precise roughly 36-step adjustment allows repeatable settings for different brew methods.
• Smooth handle action with low fatigue thanks to the internal bearing and balanced design.
• Solid, durable construction and easy disassembly for cleaning.

Cons

• Limited capacity for larger servings; reported fill often around 20-22 g rather than a very large hopper.
• Manual grinding is slower than electric grinders, so it is less suitable for high-volume or very quick routines.
