For pour-over, grind single-origin coffee medium-fine, about the feel of table salt. Specialty roasters like Blue Bottle and Fellow put pour-over in that same zone for any beans.
The single-origin label does not create its own grind category. The brewer shape, roast level, bean density, processing style, and your own taste set the dial, according to Fellow’s grind chart, which organizes settings by brew method rather than by origin.
Time is your first sanity check. Most pour-overs should finish draining in roughly two and a half to four minutes, with Chemex running a touch longer.
Start With Your Dripper, Not the Bean’s Passport
Your first grind setting comes from the dripper’s geometry. Cone-shaped brewers drain faster, flat-bottom brewers drain slower and steadier, and thick paper slows everything down.
A conical brewer like the Hario V60 pushes water straight down through a deep bed, so it wants the finer end of the medium range. Key specifications:
- Spiral ribs inside the cone guide the pour evenly
- Uses size 01 or 02 paper filters
- Available in plastic, glass, ceramic, or metal
Use the table below to pick your first grind setting for your dripper. Blue Bottle’s grind chart treats pour-over as a range rather than a single setting, so treat these numbers as starting points only.
| Dripper | Geometry and flow | Starting grind (adjust by taste) | Kitchen texture check | Typical drain window |
|---|---|---|---|---|
| Hario V60 / Origami | Conical, fast flow | Medium-fine | Table salt | About 2:30 to 3:15 |
| Kalita Wave / Fellow Stagg [X] | Flat-bottom, restricted flow | Medium | Medium sand | About 2:45 to 3:30 |
| Chemex | Conical, thick paper filter | Medium to medium-coarse | Coarse kosher salt | About 3:30 to 4:30 |
The Chemex’s thick filter holds back the water, so a slightly coarser start keeps the brew from dragging. On a numbers-based grinder, Barista Hustle pegs a typical pour-over target between 500 and 700 microns for conical drippers.
Brewer geometry tells you where to start. Bean traits tell you which way to lean after that.
Single-Origin Is a Sourcing Label, Not a Grind Setting
Single-origin means the beans trace to one farm, co-op, or region instead of a blend. It tells you where the coffee grew, not where your burr setting should sit, and no origin name on the bag changes your grinder directly.
Single origins are prized for distinctive acidity, sweetness, and fruit character, and most premium lots are roasted light to protect those flavors. That delicacy raises the stakes: a grind too coarse can taste sharp and underdeveloped, while a grind too fine can mute the nuance and tip into bitterness.
What the origin actually determines is the physical nature of the beans, and that is what nudges the dial.
Bean Density, Processing, and Roast Shift the Dial
Jonathan Gagné, the physicist behind The Physics of Filter Coffee, finds that dense, high-grown washed coffees, like Ethiopian or Kenyan lots, shatter into more fines during grinding. Fines are dust-like particles far smaller than the rest of the grounds, and they migrate down, lodge in the filter’s pores, and multiply resistance to water, which can drag out the drawdown or stall it.
To compensate for fines-heavy beans, Gagné writes that you can grind slightly coarser or pour with less agitation. Softer, lower-grown beans break into more even pieces and often want a slightly finer grind to keep extraction up.
On solubility, though, guidance genuinely splits into two camps. One common practice starts dense, light-roast singles slightly finer because their flavors release slowly, and a too-coarse cup turns hollow and sour.
The fines-focused view, drawn from Gagné’s work, leans the same beans slightly coarser to avoid clogging. Taste settles the argument: sharp, thin, and fast-draining says go finer, while harsh, muddy, and slow says go coarser.
Processing adds its own tilt. Washed coffees taste clean and crisp and tolerate extraction well at a standard medium-fine, while natural and honey-processed lots carry more fruit sugars and chaff, so many brewers start them a touch coarser to avoid astringency and stalling.
Roast level matters too. Hard, light roasts give up flavor slowly, so grind finer for them; dark roasts turn brittle and extract quickly, so start a touch coarser.
Grind and water temperature also interact, so light roasts pair well with water just off the boil. And fresher, recently rested beans behave differently at the grinder than stale ones, so it helps to know how fresh those beans should be before you blame the setting.
Dial In by Taste, With Drain Time as Backup
Taste is the final judge, every single brew. A sour, sharp, hollow cup that lacks sweetness and drains fast usually points to under-extraction, and the fix is a finer grind.
A bitter, drying, sandpapery astringency suggests the opposite problem, and Barista Hustle ties that sensation directly to grinding too fine. The fix there is a coarser step to open the bed.
Change only one variable at a time, one small step per brew. Stumptown’s brew guides are built the same way, tuning grind, ratio, and pour technique together rather than all at once.
Drain time backs up your palate, since grind size shapes both surface area and how tightly the bed packs. Extraction is the whole game here, and the Specialty Coffee Association frames balanced extraction as pulling roughly 18 to 22 percent of each ground into your cup.
Ratios stay supportive, not central: common starting recipes use about 1 gram of coffee per 15 to 17 grams of water. Keep the ratio fixed while the grind does the talking.
Finding Medium-Fine on Your Own Grinder
No chart can hand you a universal dial number, because every model speaks its own language. Blade grinders cannot reach this zone at all; they smash beans into chunks mixed with dust, which is exactly the particle mess this post is helping you avoid.
A burr grinder like the Baratza Encore ESP makes the whole process repeatable. Key specifications:
- Conical steel burrs for even grounds
- Forty stepped settings across espresso and filter ranges
- Works with a portafilter or the included grounds bin
Burr shape plays a subtle role as well. Conical burrs tend to throw a wider mix of sizes with more fines, while flat burrs tend toward a more uniform distribution, so some pour-over fans prefer flat burrs for clarity.
Calibration is a simple routine: grind a small sample, rub it between your fingers, and check for a table-salt feel. Then brew, time the drain with a scale or timer, taste, and step one setting at a time.
A single drop of water on the beans before grinding, called the Ross Droplet Technique, tames static and keeps grounds from clinging. Repeat the routine whenever you open a new bag, since a natural-processed Ethiopian and a washed Colombian from the same shelf rarely agree on one setting.
The same taste logic carries over to other brewers at their own settings, whether settings for single-origin espresso or grind advice for auto-drip machines. Those methods live at different fineness levels, but the sour-to-finer and bitter-to-coarser rules travel with you.
Your First Brew Starts Today
Grind your single-origin coffee medium-fine for pour-over, near the feel of table salt, roughly the 500 to 700 micron band Barista Hustle describes. Expect a drain around two and a half to four minutes, then judge by taste alone.
Sharp and fast means finer, harsh and slow means coarser, and one small step per brew gets you there. Brew the same coffee twice tomorrow with settings one step apart, and let the cup pick the winner.
