Ask the Best Coffee Grinder for Pour Over How Much It Holds

Every grinder on this page is sold on precision. Five of the ten publish a step size per click, and the numbers are tiny: 16 to 31 microns, thinner than a human hair. Those are espresso numbers. Espresso is the brew where a single click can change a shot.

Pour-over is the forgiving end of coffee. A filter grind is far coarser than any of these steps, and the difference between two adjacent clicks on any grinder here is a nudge, not a new recipe. So the micron figure, the one most of these listings lead with, is rarely what decides whether a grinder suits a V60 or a Chemex.

What does decide it is a plainer number: how many grams the grinder holds. A single V60 cup is commonly brewed with somewhere around 15 to 20 grams of beans. A Chemex for two or more is usually 30 grams and up. A grinder that cannot take your dose in one load makes you grind twice, every morning.

Six of these ten listings state a capacity. The range runs from 15–20g to 50g, more than double from bottom to top. Four say nothing at all, including the best-reviewed grinder on the page.

The irony is in who says what. The only listing that claims its grinder is “specifically designed for pour-over lovers” is the 1Zpresso Q Air, and it is the one that holds the least: 15–20 grams, one V60 and no more. The largest stated capacity, 50 grams, belongs to an OXO electric whose listing never mentions pour-over at all.

And not one of the ten names a V60 or a Chemex. Five name pour-over or filter coffee somewhere in the title or bullets. The two biggest review samples on the page, the Timemore C3S Pro at 1,727 ratings and the Kingrinder K6 at 1,009, never mention a brew method by name.

Burr size, the spec enthusiasts argue over, is published by only three: 42mm, 45mm and 49mm, and the 49mm is a flat burr on a listing that sells itself on espresso. If you want the wider argument about burrs against blades first, our coffee grinder guide covers it; this page assumes you have already chosen burrs.

So read this roundup in grams first, then in whether the listing names pour-over, and only then in microns.

Ten grinders below. The largest stated capacity belongs to the OXO, which plugs in; the largest stated hand-grinder capacity belongs to the 1Zpresso K-Ultra.

Ratings and specifications are taken from each manufacturer’s Amazon listing as displayed on 5 October 2026 through a United States connection, and may change. Capacity is reproduced exactly as published, and the listings do not all measure the same thing: the OXO, Kingrinder and MAVO describe what the grinder holds (beans or hopper), while the 1Zpresso K-Ultra and AeroPress state the size of the catch cup for grounds. The MAVO’s step is given as 0.0167 mm (16.7 microns) and the Timemore C5 Pro’s as 0.031 mm (31 microns); the other step figures are stated in microns. “Pour-Over Named” records whether the title or bullets mention pour-over or filter coffee; no listing names a V60 or a Chemex. The Kingrinder’s spec-table dimensions (2.63 x 0.85 x 0.81 inches) cannot describe the grinder itself and have not been used, and it publishes no weight. The CafeSing ORCA go is sold by ElephantNum and showed “Only 12 left in stock” at capture. Sales ranks are shown as displayed and can be pooled across a variant family.

How We Chose These Ten

We researched current listings, compared manufacturer specifications and documentation, and examined recurring patterns in customer feedback. We did not carry out hands-on testing, and nothing below is presented as measured performance data.

• Stated capacity, recorded exactly — it is the number that decides whether a grinder handles one V60 or a full Chemex, and four of the ten never give it
• Step size per click where the listing publishes one — five do, from 16 to 31 microns; we report the figure in the unit the listing uses and convert only for comparison
• Whether pour-over is named at all — five listings mention pour-over or filter coffee; none names a V60 or a Chemex, and we did not count “various brewing methods” as a mention
• Burr size and type as stated — three publish a diameter (42, 45 and 49mm); one is a flat burr, the rest conical
• Burrs only, no blades — every grinder here uses a burr set; blade grinders were not considered for a brew method this sensitive to particle spread
• A verified live buy box — all ten confirmed in stock and deliverable in the United States on 5 October 2026, with prices taken from that buy box
• Two deliberate outliers — the OXO electric, for anyone brewing a large Chemex every day, and the flat-burr ORCA go, to show what a different burr geometry costs
• One candidate left out — the Timemore Bricks 01S electric, which had a single unit left in stock and only 24 ratings at capture

The Ten Grinders in Detail

Grams Against the Dose: Who Holds a Chemex

The number that decides a pour-over grinder, reproduced exactly as each listing gives it, read against two rough doses: about 15 to 20 grams for a single V60 cup, and about 30 grams for a Chemex for two. Your recipe may differ; the point is whether one load covers it.

Every grinder that states a capacity covers a single V60. That is the easy part, and it is why capacity barely registers in most grinder comparisons. The divide opens at the Chemex. Four listings state enough for a 30-gram brew in one load; two do not; four will not say.

The spread is wide. The OXO’s 50 grams is 2.5 times the top of the Q Air’s range, and the difference is not academic. A household that brews a large Chemex every morning would be loading the Q Air three times for one pot. A solo V60 drinker would never notice the limit.

Price follows capacity only loosely. The cheapest grinder that clears 30 grams is the OXO, and it does so with a motor. The cheapest hand grinder that does it is the Kingrinder K6. Above that, the MAVO adds a stated 45mm burr, and the K-Ultra adds the largest hand-grinder catch, 35–40g, at the top of the range. The AeroPress grinder, one of the dearest, stops at 25 grams.

Two definitions are hiding in that column. The OXO, Kingrinder, MAVO and Q Air describe what goes in: beans or hopper volume. The K-Ultra and AeroPress describe what comes out: the catch cup for grounds. For grinding in one load the two amount to the same limit, but read the wording: a catch cup figure tells you the most one grind can deliver, a hopper figure the most you can load.

The four silent listings are not small brands. They include the best-reviewed grinder on the page, the Timemore C3S Pro, and its sibling the C5 Pro. If you brew Chemex, the absence of a gram figure is a reason to weigh a load yourself in the first week, on a kitchen scale that reads to the gram, before you build a routine around it.

Five Step Sizes, and All of Them Are Espresso Numbers

Half the listings here lead with how finely they adjust. This is what they publish, converted to microns where needed so the figures sit side by side, with the travel per full turn worked out from the stated clicks.

The five stated steps run from 16 to 31 microns. Even the largest is a small fraction of the particle size a pour-over grind produces. That is why these figures read as espresso specifications: an espresso shot is the brew where moving the burrs by a few hundredths of a millimetre can change the result, and where an adjustment this fine earns its price.

Pour-over is more tolerant. You will find a V60 setting and a Chemex setting, a little coarser, and spend most of your time within a handful of clicks either side. A 31-micron step on the Timemore C5 Pro is, for that purpose, as usable as a 16-micron step on the Kingrinder. Neither is a reason to buy or reject a grinder for filter coffee.

What does matter is where the adjustment lives. The Kingrinder, MAVO, K-Ultra and ORCA go all adjust from the outside of the body, so you can switch between a V60 grind and a Chemex grind without unscrewing anything. Both Timemores use an adjustment nut, and the C3S Pro and C5 Pro listings never describe an external ring. If you brew two methods, that difference will show up every day; the micron figure will not.

The silent five are not necessarily coarser. The Q Air states 30 clicks per rotation and the AeroPress states 60 settings, but neither says how far a click moves. We have not guessed. The OXO’s “15 settings and 29 micro-adjustments” is the only electric option here, and its resolution is unknowable from the listing.

Nobody Says V60, and the Biggest Sellers Say Nothing at All

Which listings actually claim pour-over, which claim espresso, and how many ratings sit behind each group.

No listing on this page names a V60 or a Chemex. Five name pour-over or filter coffee. Six name espresso. Three name no brew method at all, and those three are the Timemore C3S Pro, the Kingrinder K6 and the OXO: the three largest review samples on the page.

Add the samples up and the pattern is stark. The five listings that mention pour-over or filter share 660 ratings between them. The three that name no method carry 3,338. Of the 4,201 ratings across all ten grinders, roughly four in five sit on listings that never say what the grinder is for.

That is not a reason to distrust them. A grinder with a good burr and a sensible range will grind for a V60 whether or not the listing says so, and buyers clearly know it. But it does mean a search for “pour over” on a product page is a poor filter. The grinders that use the phrase are mostly newer, smaller-sample listings that also promise espresso; the one that is truly built around pour-over, the Q Air, holds a single cup.

Burr size tells the same story. Only three listings state it, at 42, 45 and 49mm, and the largest is a flat burr sold on espresso. The grinders with the strongest records publish no diameter at all. If burr size is your deciding spec, you are choosing among the C5 Pro, the MAVO and the ORCA go, and all three have fewer than 220 ratings.

Best Alternatives

If none of the ten fits, these are the routes worth considering instead.

What Each Step Up Actually Buys

The budget tier: capacity or reputation, rarely both. The COLETTI Crag states nothing measurable. The 1Zpresso Q Air is the pour-over specialist and holds one V60 dose. The Timemore C3S Pro has the best record on the page and no published capacity. The OXO holds 50 grams and plugs in. Pick the one whose single strength matches your brew.

The mid-range: the published-numbers tier. The Kingrinder K6 states a 25–35g hopper, a 16-micron step and an external ring, on 1,009 ratings. The Timemore C5 Pro states a 42mm burr and a 31-micron step but no capacity. The MAVO Phantox Pro states a 45mm burr, a 30g capacity and a 0.0167mm step. This is where a pour-over buyer gets the most verifiable grinder for the money.

The premium tier: features beyond pour-over. The ORCA go buys a 49mm flat burr pitched at espresso. The AeroPress grinder buys Italian titanium-coated burrs and a body that packs inside an AeroPress. The 1Zpresso K-Ultra buys the largest hand-grinder catch, an espresso-capable range and a travel case. None of these is better at a V60 on paper; each is better at something else.

The jump that matters for pour-over comes earlier: from the Q Air to the K6 buys roughly 15 grams more capacity at the top of the stated range, plus a published step size and an external adjustment.

What to Check Before You Buy

Weigh Your Actual Dose

Before you compare grinders, know what you brew. Put your usual scoop of beans on a scale for a week. A single V60 cup is commonly 15 to 20 grams; a Chemex for two is often 30 grams or more; a full Chemex for a household can be far higher. That number, not the micron figure, tells you which half of this page to read.

Match Capacity to Your Brewer

A grinder that holds 15–20g is a V60 grinder. One that holds 30g or more covers a two-person Chemex in one load. If your brewer changes with the day, buy for the largest dose. Our pour-over coffee maker guide covers the brewers themselves, and their sizes are worth knowing before you choose the grinder.

Treat a Missing Capacity as a Question

Four of these ten state no capacity at all, including both Timemores. That does not mean they are small. It means you cannot plan a Chemex around them from the listing, and you should weigh a full load on arrival while the return window is still open.

Prefer an External Adjustment If You Brew Two Ways

The Kingrinder, MAVO, K-Ultra and ORCA go adjust from the outside. If you switch between a V60 grind and a coarser Chemex grind, that saves a disassembly every time. If you only ever brew one way, it matters much less.

Do Not Pay for Microns You Will Not Use

Every stated step on this page, from 16 to 31 microns, is finer than pour-over needs. The finest steps are an espresso feature. If you will never pull a shot, a grinder that lists 30 clicks per rotation and no micron figure is not at a disadvantage for a V60.

Read the Cleaning Instructions

The MAVO says “DO NOT washable with water”; the COLETTI says every component is dishwasher safe. Most of the rest describe brush cleaning and tool-free disassembly. Pour-over shows stale oil and old fines quickly, so pick a grinder whose cleaning routine you will actually follow.

Budget for the Rest of the Kit

A grinder is one third of a pour-over setup. The other two are a scale and a kettle you can pour slowly and steadily. If you are building from scratch, a temperature-controlled gooseneck from our electric kettle guide will do more for a V60 than the difference between a 16-micron and a 20-micron step.

Common Mistakes

• Buying on microns for a pour-over. The stated steps run 16 to 31 microns, and every one is finer than a V60 needs.
• Ignoring capacity until the first Chemex. The Q Air holds 15–20g; a Chemex for two at 30g means grinding twice.
• Assuming silence means small. Four of ten state no capacity, including the best-rated grinder on the page; weigh a load before you rely on it.
• Filtering by the words “pour over”. Five listings say it, and they share 660 ratings; the three that name no method carry 3,338.
• Looking for “V60” or “Chemex” in a listing. None of the ten mentions either brewer by name.
• Paying for range you will not use. The K-Ultra is far dearer than the K6, and the extra is mostly espresso capability and convenience.
• Comparing a catch cup with a hopper. The K-Ultra’s 35–40g and the AeroPress’s 25g describe grounds out, not beans in.
• Washing the wrong grinder. The MAVO forbids water; only the COLETTI claims its parts are dishwasher safe.

Who Should Buy Which

Buy the KINGrinder K6 if you grind by hand for one V60 or a two-person Chemex. A 25–35g hopper, a 16-micron step on an external ring, and 4.6 across 1,009 ratings: the most published numbers on the largest well-rated sample.

Buy the 1Zpresso Q Air if you brew one V60 a day. It is the only listing built around pour-over, it holds 15–20g, and at 0.8 pounds it travels anywhere, including inside an AeroPress plunger.

Buy the OXO Brew Compact Conical if you brew a Chemex for the household. 50 grams in one load and a motor to grind it, from a listing sold by Amazon.com with 2K+ bought in the past month.

Buy the 1Zpresso K-Ultra if you also pull espresso and want a big catch cup. 35–40g of grounds, 20 microns per click over 100+ clicks per turn, and a travel case.

Buy the MAVO Phantox Pro if you want the burr size and capacity in writing. 45mm burr, 30g capacity, 0.0167mm per click, and pour-over named in the title.

Buy the AeroPress Manual Grinder if you travel with an AeroPress and a dripper. The whole grinder packs inside the brewer, the burrs are Italian-made and titanium-coated, and the catch holds 25g.

Buy the TIMEMORE C5 Pro if you want a stated 42mm burr at the lowest price. It also states a 0.031mm step, but not a capacity, so weigh your dose.

Buy the TIMEMORE C3S Pro if you trust 1,727 ratings more than a spec sheet. 4.8 stars and #2 in Manual Grinders, priced below list; it states no capacity, step or burr size.

Buy the CafeSing ORCA go if you want to try a flat burr by hand. 49mm and 16 microns per click, sold on espresso, with only 44 ratings and 12 units showing at capture.

Buy the COLETTI Crag if you want a burr grinder for the trail and the odd V60. 4.5 across 159 ratings and a 1-year warranty, with no published specifications to compare.

Frequently Asked Questions

Final Verdict

Every grinder on this page sells precision, and for pour-over it is the wrong number to buy on. Five state a step between 16 and 31 microns. All five are fine enough for any filter grind, and the finest of them are built for espresso.

The number that decides a pour-over grinder is grams. Six listings state one, from 15–20g to 50g. Every one covers a V60; only four cover a 30g Chemex in a single load. Four state nothing, including the best-reviewed grinder here.

And the words on the listing will not help you. None of the ten names a V60 or a Chemex. The listing most devoted to pour-over, the Q Air, holds the least; the three biggest review samples name no brew method at all, and carry roughly four in every five ratings on the page.

If you buy one grinder from this page, make it the KINGrinder K6 — a 25–35g hopper that spans a single V60 to a Chemex for two, a published 16-micron step on an external ring, and 4.6 stars across 1,009 ratings. If you only ever brew one V60, the Q Air was built for you; if you brew a Chemex for the house, the OXO holds 50 grams.
