Some grinders do the job. The C5 Pro does it better.
Timemore's Chestnut C series has always punched above its weight — precise, portable, and built to last. With the C5 Pro, they've taken everything that worked and quietly made it exceptional. New burrs. A smarter dial. A body that feels like it means business. The result is a grinder that belongs on any serious home brewer's counter, whether you're pulling shots before work or chasing a slow Saturday pour-over.
The Burrs
At the heart of the C5 Pro is the new S2C-042-III burr set — Timemore's largest conical burrs yet at 42mm, machined from SUS420 hardened stainless steel via 5-axis CNC and hardened to 55–58 HRC. The grinding path runs 16.23% longer than the previous-generation S2C660, which translates to a tighter particle distribution across the board: more fines where espresso needs them, fewer where pour-over doesn't. The outcome in the cup is brighter acidity, better balance, and a clarity that holds up as the coffee cools. A 5% improvement in grind consistency over the C3S Pro means you can push extractions higher without tipping into astringency.
The Dial
The C5 Pro's numbered stepped dial moves 0.031mm per click with 48 clicks per revolution, and every position is clearly numbered, so you're dialing in from a real reference point instead of counting from zero each time. It's a small change that makes a meaningful difference when you're tweaking your espresso recipe at 6am.
Here is our recommended grind settings for the C5 Pro:
- Espresso / Moka: 5–8 clicks
- Pour-over: 10–14 clicks
- French Press: 14–17 clicks
The Build
The C5 Pro is all-metal construction with a unibody aluminum alloy and stainless steel construction that doesn't flex, rattle, or wear in. Custom high-precision bearings keep the burrs aligned on dual axes with tolerances as tight as 0.007mm, so every rotation is smooth and stable. The 53mm body is wrapped in a refined grid engraving that gives you a confident, slip-free grip even with wet hands. A new XL funnel opening makes dosing easier and less messy, while the grippy silicone base keeps things planted and quiet on any surface.
Disassembly is straightforward. The drop-out burr design means cleaning and maintenance won't eat into your morning.

Note: The C5 series excels with traditional espresso roasts. Light-roasted or single-origin beans may be harder to grind by hand due to their higher density. Do not wash the grinder with water — clean with a dry brush after use.
Colors of actual products might show up slightly different than in the product photos. This is due to the various settings of monitors. Every monitor or mobile display has a different capability to display colors, and every individual may see these colors differently. In addition, lighting conditions at the time the photo was taken can also affect an image's color.
Products that have a shimmering coating will also show differently under different lighting setup. Colors might appear different even under a fluorescent light or a warmer shade bulb.
Please do not wash or rinse this grinder, utilize a brush or air hand pump to clean from debris, and storing in a cool dry place.
This grinder was designed with coffee beans in mind, we cannot guarantee the grinder will hold up on wear for other items.
Please keep this grinder out of reach from from children, the burr edges are quite sharp, use caution while operating and do not place fingers near the gears.
We suggest consulting a professional technician for any repairs or replacement needed.
Please do not disassemble or replace any parts of this grinder personally as there is a possibility of damage or issues in operation on reassembly.
UFO Dripper V3
Regular price $50.00

The 2026 World Brewers Cup Champion Nas Jaafar (representing Malaysia) brewer of choice.
The UFO Dripper V3 is a standalone dripper that can be adapted to the "Hario Switch" brewing system.
Geometry That Guides Extraction
At the core of the V3 is an 80° interior angle designed to promote steady drawdown while maintaining even bed saturation. This angle supports efficient flow through the coffee bed, helping reduce channeling and minimizing stall. Rather than relying on aggressive flow restriction or mechanical intervention, the structure itself regulates movement and extraction.
This geometry also improves performance across a wider grind spectrum - extraction remains controlled and predictable, allowing grind size and pour adjustments to translate clearly into the cup.
Profiles remain expressive yet structured.
Negative Channels and Flow Stability
The negative channel design supports balanced airflow during drawdown, preventing vacuum lock and reducing turbulence. By stabilizing the brew bed and minimizing uneven water distribution, the V3 maintains clarity and a controlled flow.
The result is faster, consistent drawdown without sacrificing balance.
Expanded Capacity for Recipe Flexibility
The larger brew chamber increases practical flexibility. It accommodates higher doses and a broader range of brew ratios while offering greater tolerance for controlled agitation. This enables movement between lighter, clarity-focused brews and fuller extractions without destabilizing the bed.
Designed for Hybrid Brewing
The V3 functions as a standalone percolation dripper with stable flow characteristics. It is equally engineered for adaptation. When paired with the Hario Switch base, it becomes a hybrid immersion system.
In this configuration, you can extend contact time, hold water before release, and intentionally increase extraction depth. The same geometry that supports clean percolation also ensures controlled immersion drawdown once the valve is opened.
One brewer with two distinct extraction approaches. The 80 degree UFO Dripper V3 delivers structural clarity, adaptable workflow, and repeatable results without unnecessary complexity.
Material: Food Safe Triton Resin
Weight: 250g approx

Using Sibarist Flat Papers
UFO was designed for use with Sibarist Fast flat and B3 papers, although this template can be used to fold any flat filter. Simply fold once in half, then fold to match the angle below (feel free to take a screenshot and print this diagram).
