Timemore C3s PRO -Black Chestnut Manual Coffee Grinder Upgrade Review UK 2026

Key specifications

Design and Build Quality

With its 147 mm x 52 mm footprint, this coffee grinder is designed to sit steadily on the counter. The stainless steel body features a non-slip pattern for a firmer grip, and the bottom includes a silicone pad to help prevent sliding or dropping. The review notes an upgrade to an all-metal aluminium alloy housing, alongside a double bearing central axle and integrated durable components. A foldable handle supports portability, though it introduces small moving parts that require careful handling.

Burr Type and Grind Quality

Burr type and grind quality on the Timemore is driven by its patented S2C660 "Spike to Cut" burr design, which uses high sharp burrs and precision moulding to aim for a more even grind. In the coffee grinder burr grinder, the spikes cut rather than simply crush, so particle sizes tend to stay closer together. The result is a more uniform powder, intended to support more even extraction across beans. For espresso, pour-over, and French press, this can feel consistent.

Grind Settings and Consistency

The Timemore supports grind setting changes with fine step control, using an adjustable setting up to 0.0833mm per click. This level of incremental adjustment helps keep particle size steadier while dialing in, since small changes can be repeated for similar results. Different brew methods such as espresso, pour-over, or French press can be approached by adjusting settings gradually and then re-checking outcomes with consistent repeatability. The main limitation is that rapid switching between settings is less practical because very small clicks require patience. Overall, the grinder is built for uniformity, with consistency dependent on careful, repeatable adjustments.

Hopper and Bean Capacity

Hopper and bean capacity on the coffee grinder is determined by how much the grinder can hold at one time, rather than by the grind mechanism. The Timemore C3s Pro Black Chestnut C3s Pro Manual Coffee Grinder upgrade UK supports about 20 - 25 g of coffee beans per session, based on its stated capacity. This means beans are typically loaded into the body hopper and ground until the bin is empty before refilling, which suits single-cup and small-batch use. For larger batches, more grind cycles are required.

Noise Level and Speed

Even though the Timemore (Black) is built as a hand grinder, its noise level and grind speed depend mainly on how quickly the user turns the foldable handle and how tightly the grinder is held during grinding. The stainless steel, non-slip, all-metal aluminium alloy housing helps keep vibration down by staying stable on the counter, and the solid handle supports consistent turning. Grind setting changes are available in 0.0833 mm clicks, so finer settings call for slower, steadier cranking. Over time, a careful grip can reduce rattling, but louder grinding is still expected.

Static and Retention

Static and retention are practical issues with any burr hand grinder, as some grounds can cling to the inside walls and burr area after grinding. This can reduce how much coffee reaches the cup or filter. With the coffee grinder - Black Chestnut C3S Pro manual coffee grinder upgrade, the all-metal aluminium alloy housing and solid double bearing axle do not automatically prevent static or retention. Retention is most noticeable when grinding small batches (20-25 g) and when fine settings are used. A simple routine helps: brush out the burr area, tap the body gently, and wipe the walls before reloading.

Learning Curve and Daily Operation

With day-to-day use, the Timemore - Black can feel straightforward, but a short learning period still helps, particularly after retention is managed with brushing and gentle tapping. In the coffee grinder - Black Chestnut C3s Pro manual coffee grinder upgrade, the foldable handle and non-slip grip help it stay steady, allowing repeatable hand movements. Typical setup starts with dialling the grind click-by-click, then weighing 20 - 25 g beans for the session. Grinding follows, then the setting is adjusted up or down to hit targets, from espresso to French press, with each small change noted.

Cleaning and Maintenance

Cleaning and maintenance of this coffee grinder -Black are straightforward, with results depending on how carefully grounds are cleared after each use. Daily care begins by emptying the hopper and brushing any loose grounds from the burr area. The silicone pad on the base helps keep the grinder stable, allowing more thorough cleaning on a flat surface. Brushing after each session helps prevent leftover residue from affecting grind feel, and the body can then be wiped clean. The foldable handle should also be checked for trapped dust.

Who Is This Grinder For?

This hand grinder is for buyers who want a compact, all-metal aluminium alloy design for home use or travel. The C3s Pro centres on a non-slip stainless steel housing with a foldable handle, and it is designed for adjustable coarseness with settings up to 0.0833 mm per click. At 147 mm x 52 mm and 530 g, it is sized for packing outdoors, although it is also described as a heavier single-dosing grinder.
