Timemore: Understanding the Differences Between Slim 3, C3, S3, and Chestnut X

The grinder is often the most underestimated element in coffee preparation. Yet, it plays a central role in cup quality, long before the machine or the method.

With Timemore, the approach is clear: to offer precise, compact, and accessible manual grinders, capable of adapting to different uses, from filter to espresso.

Among the Slim, C3, S3, or Chestnut X models, the differences are not only in design, but especially in grind precision, consistency, and ease of use.

Here's what distinguishes them.

Timemore Slim 3: compactness and mobility

The Slim 3 is designed to be taken anywhere. Its slim and lightweight format makes it a grinder particularly suitable for travel or mobile use.

It is equipped with steel burrs capable of producing a consistent grind, especially suitable for gentle methods such as V60, Chemex, or AeroPress.

In practice, this allows for clean and balanced coffees, without seeking extreme precision in settings.

Compared to the C3, the adjustment possibilities remain more limited, making it less suitable for more demanding extractions.

A grinder designed for simplicity and mobility, filter-oriented.

Timemore C3 / G3: a solid entry point

The C3 marks a real step up in precision compared to the Slim.

Its improved steel burrs produce a more homogeneous grind, with less variation between particles. Result: water flows more regularly through the coffee, leading to a more balanced extraction.

In the cup, this translates to less bitterness or imbalance, and more defined flavors.

Adjustment remains simple, but precise enough to cover most methods, from filter to finer grinds for AeroPress or extractions close to espresso.

An excellent balance between accessibility and grind quality.

Timemore S3: more stability and control

Compared to the C3, the S3 improves the stability of the central axle, which keeps the burrs better aligned during grinding.

In practice, the movement is smoother, and the grind is more uniform. There are fewer variations between particles, allowing water to extract the coffee more consistently.

In the cup, this results in a more precise coffee, with better-defined aromas and fewer off-notes.

The ergonomics are also more refined, with a more comfortable grip and reduced effort, especially for finer grinds.

A more precise and more pleasant grinder to use daily.

Timemore Chestnut X: precision and total control

The Chestnut is positioned at the high end of Timemore's range.

It stands out with an external micrometric adjustment system, which allows for very fine grind adjustments, with minimal gaps between each click. This is essential for demanding methods like espresso.

The burrs produce a very homogeneous grind, with fewer "very fine" particles. Water then extracts the coffee more uniformly.

In the cup, this provides more clarity, more definition, and a better interpretation of aromas, especially for complex coffees.

Everyday experience

Beyond the technical aspects, these grinders primarily define different uses.

• The Slim 3 supports simple and mobile use, without seeking to adjust every detail.
• The C3 introduces a logic of progression, with more precise adjustments and better control.
• The S3 makes the action smoother and the results more consistent daily.
• The Chestnut X allows for going further, with very fine adjustments and total control, especially for espresso.

The choice ultimately depends on how you want to prepare your coffee: simplicity, progression, or precision.

Verdict: which grinder to choose?

• For simple and mobile use → Slim 3
• For an excellent quality/precision ratio → C3 / G3
• For more comfort and consistency daily → S3
• For maximum precision, including espresso → Chestnut X
