Coffee grind size chart for every brewing method
Ask five brewers what "medium-fine" means and you will get five hand gestures. The descriptors only become useful when you attach them to the method that needs them and the guides that publish them. This chart cross-references the grind recommendations in the equipment makers' and roasters' own brew guides — so "coarse" stops being a vibe and becomes a target.
Key takeaways
- Grind size is the main dial for extraction: finer extracts more, coarser extracts less, at the same time and temperature.
- Fast methods (espresso, moka) need fine grinds; slow methods (French press, cold brew) need coarse ones.
- Official guides describe grinds by feel: Blue Bottle calls French press "sea salt", Stumptown "breadcrumbs", Toddy "coarsest possible".
- When a cup tastes sour, grind finer; when it tastes bitter and drying, grind coarser — one step at a time.
The chart, coarse to fine
| Grind | Feels like | Method(s) | Who says so (official) |
|---|---|---|---|
| Extra coarse | Coarse sea salt, peppercorn-ish | Cold brew concentrate | Toddy instruction sheet: "coarsest grind setting possible" |
| Coarse | Sea salt / breadcrumbs | French press, cupping | Blue Bottle ("sea salt"); Stumptown ("breadcrumbs") |
| Medium-coarse | Sand, rough cornmeal | Chemex, some percolators | Chemex distributor guide (medium-coarse) |
| Medium | Regular sand, rolled oats | Auto drip, Blue Bottle pour-over | Blue Bottle pour-over guide ("medium"); Fellow guide ("medium", with per-grinder settings) |
| Medium-fine | Table salt | V60/pour-over, AeroPress, moka (upper end) | Hario V60 recipes; AeroPress how-to; Bialetti "medium-fine, not espresso-fine" |
| Fine | Slightly finer than table sugar | Espresso | illy preparation guide; Stumptown AeroPress (fine variant) |

Why each method wants what it wants
Grind size sets the surface area water can attack, and each method's contact time is fixed by physics or habit. Espresso water blasts through a puck in 25–30 seconds (illy's guide), so the coffee must be fine to give up its solubles fast. French press grounds steep for four full minutes and stay in the cup afterwards, so coarse particles keep the extraction gentle and the silt pourable. Cold brew sits for twelve hours — Toddy's coarsest-grind instruction exists precisely because long, cold water has nothing but time. Auto drip sits in between at four to six minutes of machine cycle, which is why "medium" is the default on bags and in Blue Bottle's coffee-maker guide.
Reading your own grinder
Blade grinders cannot hold a grind size — they smash and heat and produce everything from dust to gravel at once, which is why every guide above quietly assumes a burr grinder. If you use a hand grinder or an electric burr grinder with numbered settings, calibrate to the method, not to the manual: set it where the chart says, brew, taste, and adjust one step. Fellow's pour-over guide is unusually practical here — it names actual dial positions (for example, setting 5 on Ode Gen 2 burrs) rather than adjectives, and their approach of publishing per-grinder starting points is the honest one.
The adjustment rule, in one paragraph
Keep dose, ratio and temperature constant and move only the grind. Sour, thin, or "salty" cups are under-extracted: grind finer. Bitter, drying, ashy cups are over-extracted: grind coarser. Bitter and sour at once usually means the grind is inconsistent (blade grinder, or worn burrs) rather than wrong. The theory behind this lives in our grind size vs extraction explainer, and the ratio side of the equation is covered in adjusting ratio to taste.
Grind and ratio work as a pair
A fine grind at a 1:18 pour-over ratio and a coarse grind at 1:13 can land at similar strength by coincidence — and neither will taste like a proper cup. Fix the ratio first with our ratio calculator, then tune the grind. That order matters because grind is a taste adjustment while ratio is the recipe's skeleton; swap the order and you are rebuilding the skeleton every time your palate has an off day.
Old beans change the target
Coffee loses soluble content as it ages, and many brewers grind finer to compensate. If you chase a recipe written for fresh coffee with three-month-old beans, expect to end up a notch or two finer than the chart — that is a bean problem, not a chart problem.
