TIMEMORE S5 Pro Review: A Home Grinder, Not a Travel One

1. The TIMEMORE S5 Pro Verdict, in Two Sentences

The TIMEMORE Chestnut S5 Pro is a heavy, large-burr hand grinder that makes the most sense for someone who brews at home, wants one manual grinder for both pour-over and espresso, and is happy to crank for it. It is not a travel grinder, whatever the folding handle suggests, and if you already own a Chestnut S3 or brew filter only, there are better ways to spend US$179.

That is the decision in short. The rest of this review explains where the money goes, what the S5 Pro actually changes, and which grinder to buy if it is not the right one for you.

2. TIMEMORE Chestnut S5 Pro Specifications at a Glance

Specs and prices checked 22 October 2026 on TIMEMORE’s official US and EU stores. Models and pricing change without notice.

A note on that weight. TIMEMORE’s own spec table and its founding-story page both say about 910 g, while some retailer listings and reviewers quote lighter figures, from 880 g down to roughly 800 g. Either way, this is close to a kilogram of metal, and that shapes everything below.

Singapore readers: as of 22 October 2026 we could not find an official Singapore listing, local price or local warranty terms. Do not treat the US$179 figure as a local price; shipping, GST and any reseller margin will move it.

3. Who the TIMEMORE S5 Pro Is For, and Who It Is Not

This grinder suits you if:

• You brew at home, every day, and the grinder will live on the counter
• You want one hand grinder that covers espresso, moka pot and pour-over
• You dial in espresso by small steps and want a firm, repeatable click
• You prefer a heavy, planted grinder that does not wander while you crank

It is not for you if:

• You want a grinder for flights, hiking or a hotel room. Close to a kilogram is a lot of luggage
• You brew filter only. You would be paying for espresso range you will not use
• You make several espresso doses a day and do not want to crank for close to a minute each time
• You already own a Chestnut S3 and are happy with it. The step size is identical

4. Build and Design

The body is machined aluminium with diagonal engraved ridges for grip, and TIMEMORE says the S5 Pro avoids plastic in favour of metal parts, with a silicone base. The burr is 420 stainless steel, five-axis CNC machined and hardened to 58 HRC, according to the manufacturer.

The headline is the burr itself. TIMEMORE calls the 48 mm TriB-048-I its largest burr ever in a hand grinder, up from the 42 mm burr in the Chestnut S3. The company’s own explanation is that a better pre-breaker made the jump possible: the beans are broken into smaller pieces before they reach the main cutting teeth, so a burr size usually paired with a motor can still be turned by hand.

That pre-breaker is the part to read carefully. TIMEMORE describes a 12-point design that alternates straight-edged and serrated teeth, combining compression, piercing and shearing, and claims it reduces fines and produces fewer coarse particles. Those are manufacturer claims. As of this check, no independent particle distribution measurement for the S5 Pro has been published.

Smaller changes over the S3 are easier to confirm:

• Crank knob: TIMEMORE says it is 63.3% wider with 82.4% more volume than the S3’s, which reviewers credit with less hand fatigue
• Bean inlet: flared, so beans pour in without bouncing off the rim
• Catch cup: slightly larger, with a smooth interior and no inner lip, which CoffeeGeek’s review notes helps grounds fall out cleanly
• Bearings: custom, held to a 5 micron machining tolerance, per TIMEMORE

5. In Use, Day to Day

The adjustment dial sits outside the body, below the crank, so you change grind without taking anything apart. There are 90 clicks per full rotation, and TIMEMORE states each click moves the burrs 15 microns. Read that as the manufacturer’s stated mechanical step, not a promise that each click changes particle size by exactly that amount. Reviewers describe the clicks as firmer than the S3’s, and TIMEMORE says the dial was redesigned to feel like a camera aperture ring so it is hard to knock off your setting.

A detail worth knowing before you panic: at the zero setting, TIMEMORE leaves a gap of about 0.075 mm, so the burrs never touch. The company also says some chirping under uneven hand pressure is normal. Neither is a fault.

TIMEMORE’s suggested starting points on the dial are:

• Espresso: 0 to 2.0
• Moka pot: 1.0 to 3.0
• Pour-over: 5.0 to 8.0
• French press: 8.0 to 9.0

Each whole number on the dial is ten clicks. These are starting points, not answers; roast level and bean density will move you.

Speed is where the hand-grinder bargain shows. In CoffeeGeek’s hands-on review, published 18 September 2026 on a unit supplied by TIMEMORE, a 16 g pour-over dose at setting 60 took about 20 to 30 seconds, while an 18 g espresso dose at setting 9 took 45 seconds to a minute. A minute of steady cranking is fine for one morning shot. For three or four milk drinks back to back, it gets old quickly.

Retention (grounds left inside the grinder after a dose) and static are reported as low by reviewers, but nobody has published a weighed retention figure yet. CoffeeGeek misted the beans with a drop of water before grinding, a common trick that cuts static on any hand grinder.

6. Results in the Cup

TIMEMORE’s own positioning is useful here. Its founding-story page says the S5 Pro is for people who want more body and structure, especially in espresso, while the S3 remains the choice for a clean, sweet cup. In other words, the manufacturer itself does not claim the S5 Pro is a straight upgrade for every brew.

Independent reviews broadly agree with that framing:

• CoffeeGeek rated both pour-over and espresso highly, describing clean, fruity filter cups and espresso with good clarity and a slightly acidic lean
• We Are The Mouth scored it 4.5 out of 5 for filter and 4 out of 5 for espresso, and found the 1Zpresso ZP6 Special gave more clarity on pour-over

What is missing is long-term evidence. We found no published data on how the folding handle, the dial or the calibration hold up after a year of daily use. That is not a mark against the S5 Pro, it is simply too new, but it means you are buying on launch reviews.

7. Where It Falls Short

Skip the S5 Pro if:

• You travel with your grinder. At around 900 g it is heavy to carry, and every review we read flags the weight as a drawback for travel. The folding handle is a storage feature on a counter, not a portability one
• You already own a Chestnut S3. Same 90 clicks, same 15 micron step, and TIMEMORE’s own FAQ calls the dial precision identical. The S3’s handle also folds. What you gain is a larger burr and a bigger knob, not a new level of control
• You brew filter only. A filter-focused grinder delivers more clarity on pour-over for a similar price, as the ZP6 Special comparison above suggests
• You need it now. At the 22 October 2026 check, TIMEMORE’s US and EU stores both listed it as out of stock on presale, with orders expected to ship by the end of January
• You want to see measured particle data. The pre-breaker and fines claims are TIMEMORE’s own, not yet independently tested

The width is also worth a mention. A 56 mm body is comfortable for most hands, but one reviewer notes it can feel large in smaller ones.

8. Alternatives Worth Considering

Prices checked 22 October 2026 on each manufacturer’s official US-dollar store.

• TIMEMORE Chestnut S3, US$159. Same external 15 micron dial, a folding handle and a 42 mm burr, for US$20 less. If you brew mostly light roast filter and like a bright, sweet cup, TIMEMORE itself points you here. Read our TIMEMORE Chestnut S3 review.
• 1Zpresso ZP6 Special, US$209. 1Zpresso says it is designed primarily for pour-over, and it does that job with more clarity in the one head-to-head we found. Lighter too. Do not buy it for espresso.
• 1Zpresso J-Ultra, US$199. The espresso specialist: 48 mm espresso burrs, an external dial at 8 microns per click and a listed 670 g, per 1Zpresso. Choose it if shots matter more than filter. See our 1Zpresso J-Ultra review.
• 1Zpresso K-Ultra, US$259 on sale (US$289 list). An all-rounder with an external dial at 20 microns per click and a folding handle, for readers who want a long track record rather than a launch-season product. See our 1Zpresso K-Ultra review.

9. Verdict: Is the TIMEMORE S5 Pro Worth It?

Buy the TIMEMORE Chestnut S5 Pro at US$179 if you brew at home, want espresso and pour-over from one hand grinder, and value a heavy, firm-clicking build that stays put on the counter. For that reader, it is a well-made grinder at a fair price against a US$259 K-Ultra.

If you mostly brew filter, buy the 1Zpresso ZP6 Special. If you already own an S3, keep it. If you travel, look at something half the weight. And if you pull several espresso shots a day, the honest answer is an electric grinder, not a bigger hand one.

FAQ

Is the TIMEMORE S5 Pro good for espresso?

Yes, it can grind fine enough for espresso, and TIMEMORE suggests dial settings of 0 to 2.0 for it. Expect 45 seconds to a minute of cranking for an 18 g dose, based on CoffeeGeek’s review. It is comfortable for one or two shots a day, not for a household of milk drinkers.

What is the difference between the TIMEMORE S5 Pro and the S3?

The S5 Pro has a 48 mm burr against the S3’s 42 mm, a redesigned 12-point pre-breaker, a larger crank knob and a firmer dial. Both have 90 clicks per rotation at 15 microns per click, and both have folding handles. The S5 Pro is about US$20 more at US$179.

How much does the TIMEMORE S5 Pro weigh?

TIMEMORE lists it at about 910 g. Some retailers and reviewers quote lighter figures, down to roughly 800 g, but either way it is a heavy hand grinder built for the kitchen rather than a backpack.

Is the TIMEMORE S5 Pro good for travel?

Not really. Its weight is the drawback reviewers keep returning to, and the folding handle saves counter or drawer space rather than making it light. A smaller, lighter hand grinder is the better travel choice.

How many grind settings does the TIMEMORE S5 Pro have?

The external dial has 90 clicks per full rotation, with each click moving the burrs 15 microns by TIMEMORE’s figure. The dial is numbered 0 to 9, with ten clicks per number.

Is the TIMEMORE S5 Pro available in Singapore?

We could not find an official Singapore listing, price or warranty as of 22 October 2026. Check TIMEMORE’s official store and authorised local resellers before buying, and do not assume the US$179 US price applies.
