Timemore · Conical burrChestnut C3 Max
A bigger-hopper version of Timemore's budget-darling C3 hand grinder, built around the same 38mm S2C conical burrs but scaled up to a 30g dosing chamber for grinding more than a single cup at a time.
The short version
It is the C3's grind quality with a bigger hopper bolted on, which is exactly what you want if you brew for two but do not want to pay Pro/S prices.
Accept that the handle does not fold and the internal parts are part-plastic, so it is a kitchen-counter grinder more than a travel one.
Why people buy it
- 38mm S2C660 conical burrs give clean, consistent results across brew methods, including usable espresso settings
- 30g hopper handles bigger pour-over batches or back-to-back cups without refilling
Why they don’t
- Non-folding handle and part-plastic internal stabilization parts make it less travel-friendly than the Pro/S variants
The full tally
- 38mm S2C660 conical burrs give clean, consistent results across brew methods, including usable espresso settings
- 30g hopper handles bigger pour-over batches or back-to-back cups without refilling
- Dual-bearing shaft keeps grind particle size consistent and the crank spins smoothly
- Aggressively priced against other hand grinders with metal conical burrs
- Non-folding handle and part-plastic internal stabilization parts make it less travel-friendly than the Pro/S variants
- Espresso range is narrow; only a handful of the roughly 36 click positions are actually fine enough for espresso
- Grinding speed lags behind the newer S2C burr generations used in updated C3S models
What the community knows
Years of owner threads, distilled — well regarded.

Worth knowing before you buy — Most hand-grinder buyers wish they'd understood the espresso wall BEFORE they committed; Chestnut C3 Max is the grinder that teaches that lesson early and saves the false-start money.
Known weak points — Burr loosening reported in some units after extended use; handle stress at high-torque settings on lighter alloys; otherwise no systemic failures documented in community record.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who want espresso precision typically move to the C3 ESP or C3S Pro for finer click resolution, or step up to a premium single-dose electric grinder once daily cup count or dial-in obsession grows.

Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. A balanced burr set: rotate origins freely — it will keep up.

Common questions
Can the Timemore Chestnut C3 Max grind fine enough for espresso
Yes, but only in a narrow band near the fine end of its roughly 36-click range; most of the adjustment range is better suited to pour-over and French press.
How is the C3 Max different from the C3 Max Pro
The C3 Max Pro adds a foldable metal handle for travel; the standard C3 Max uses a fixed, non-folding handle and is intended more for home counter use.
