The best grind size for pour over is a medium grind — roughly the texture of coarse table salt or fine sea salt, coarser than espresso and finer than French press. That medium setting suits almost every cone dripper and is the sensible place to start whether you brew a Hario V60, a Kalita Wave, or a Chemex. From there you nudge a little finer for a flat-bottom brewer or a big Chemex, and a little coarser if the brew runs slow or the cup turns bitter — because on a pour over the grind is what sets how fast the water drains through the bed.
The short answer: the best grind size for pour over
Start at medium. If you buy pre-ground coffee, a bag labeled "medium" or "drip" is your target; if you grind your own, aim for a texture between coarse table salt and fine sea salt — grainy and sandy between your fingers, not powdery and not gravelly. That single setting makes a clean, balanced cup across most beans and most cone drippers, which is why it is the honest default rather than a compromise.
This page stays focused on one variable: how coarse or fine to grind. The dose, the water temperature, the bloom, and the staged pour all matter just as much, but those belong to the full method rather than this page. For the complete walkthrough of gear, ratio, and technique, see our pour-over coffee guide. Here we keep our eyes on the grind and how to adjust it by dripper and by taste.
Why grind size controls a pour over
A pour over has no pump and no pressure. Gravity alone pulls hot water down through the bed of grounds and out through the filter, which means the grind is doing something very specific: it sets how fast that water drains. Grind fine and you create a dense, tightly packed bed with lots of surface area, so water moves through slowly and dissolves more flavor. Grind coarse and the bed is loose and open, so water rushes through and dissolves less.
That is why grind size is the master dial on a pour over. Go too fine and the flow stalls or clogs — the water lingers far too long against the coffee and over-extracts, giving a cup that tastes harsh, dry, and bitter, sometimes with the brew backing up and pooling on top of the bed. Go too coarse and the opposite happens — the water sprints through before it can dissolve much, leaving a thin, weak, and often sour cup because extraction was cut short. Medium threads the needle: enough resistance to give the water proper contact time, but not so much that it chokes. Every coffee, roast, and dripper behaves a little differently, so treat these as tendencies to nudge against rather than fixed laws.
Pour over grind size by dripper
The dripper shape steers the flow, so the ideal pour over grind size shifts slightly depending on which cone you own. These are starting points to hedge and adjust from, not rules.
- Cone drippers (V60 and similar): medium to medium-fine. A cone like the Hario V60 has a single large hole and drains fast, so a slightly finer grind adds the resistance that slows the water down and builds flavor. If your grind size for V60 runs too coarse, the brew races through and tastes weak and sour. This is the classic pour over grind.
- Flat-bottom drippers (Kalita Wave and similar): medium. A flat bed sitting over small holes drains more slowly and evenly on its own, so it is happy with a straightforward medium grind and tends to be forgiving of small pouring errors.
- Chemex: medium to medium-coarse. The Chemex uses a thick, heavy paper filter that slows the flow considerably, so a slightly coarser grind keeps the water from stalling behind it. A large Chemex brewing several cups leans coarser still. If your Chemex grind size is too fine, the thick filter and the fine bed together can drag the drawdown out and tip the cup bitter.
| Dripper | Grind | Note |
|---|---|---|
| Hario V60 (cone) | Medium to medium-fine | Cone drains fast, so a finer grind adds resistance. A bright, clean starting point. |
| Kalita Wave (flat-bottom) | Medium | Flat bed drains evenly and is forgiving of an uneven pour. |
| Chemex | Medium to medium-coarse | Thick filter slows the flow, so grind a touch coarser; coarser still for a big batch. |
Where pour over sits on the grind scale
It helps to picture the whole grind spectrum as a slider from powder to gravel. The quick mental model is simple: espresso is fine, pour over is medium, French press is coarse. Pour over lives right in the middle — finer than the breadcrumb-coarse grind a French press wants, and much coarser than the powdery grind an espresso machine needs.
If you already dial espresso at home, a pour over grind is several notches coarser than that setting. For where the fine end of the scale lives and why it behaves the way it does, see our guide to espresso grind size. And for a full tour of every setting from the finest Turkish grind through to French-press-coarse, our coffee grind size chart maps the entire spectrum in one place.
Dialing in your pour over grind by taste and drawdown time
The best part of grind size is that the cup — and the clock — tell you exactly which way to move. On a pour over you get two clues: how the coffee tastes, and how long the brew takes to drain, known as the drawdown time. A typical single-cup pour over draws down in roughly 2.5 to 3.5 minutes; much faster or much slower than that is a signal. Both clues usually point at the same fix.
If the coffee tastes bitter, harsh, or dry, or the brew drains slowly and the water pools on top of the bed, you are over-extracting — go a step coarser so the water moves through faster. If the coffee tastes weak, thin, or sour, or the brew rushes through in well under a couple of minutes, you are under-extracting — go a step finer to slow the flow and add contact time. Change one thing at a time and re-taste, because small moves matter more than big ones, and a single notch on the grinder often shifts the cup more than you would expect.
Why a burr grinder matters more than the exact setting
Whatever number you land on, the evenness of the grind matters as much as its coarseness — arguably more on a pour over, where clean, even extraction is the whole appeal. A pile of grounds with lots of fine dust alongside big boulders extracts unevenly: the fines over-extract into bitterness while the boulders stay sour and under-developed, muddying the same cup. Those fines also migrate into the bed and clog the flow, stalling your drawdown in ways that are hard to predict.
This is where a burr grinder earns its place. It crushes beans to a far more uniform particle size than a spinning-blade grinder, which chops unevenly and leaves you guessing between brews. You do not need anything elaborate for pour over — just even particles and a setting you can return to. Our coffee grinder guide covers what to look for. Grinding right before you brew helps too, since coffee stales fastest once it is ground.
The takeaway
The best grind size for pour over is medium — coarse table salt or fine sea salt, sitting neatly between fine espresso and coarse French press. Nudge toward medium-fine for a fast cone like a V60, keep it medium for a flat-bottom Kalita, and go a touch coarser for a Chemex or a big batch. Then let taste and drawdown time do the fine-tuning: coarser if it is bitter or slow, finer if it is weak or fast. Grind evenly, grind fresh, and a pour over rewards you with the clean, expressive cup the method is loved for.
