The right grind for medium-roast coffee on a pour-over is medium-fine, close to coarse sand or kosher salt in size. Set your grinder there before adjusting anything else.
Blue Bottle’s grind size guidance places pour-over right in that medium-fine zone, aiming for controlled extraction. The Coffee Compass grind chart agrees, slotting pour-over into the medium-to-medium-fine band for nearly every dripper.
Medium roast is also the forgiving roast level, so this starting point usually lands in the sweet spot. After that, taste and drain time tell you which way to nudge the grind.
What Medium-Fine Grind Looks Like
A medium-fine pour-over grind sits between espresso-fine and auto-drip coarse: grains visibly larger than table salt but smaller than flaky sea salt.
James Hoffmann’s The World Atlas of Coffee (2018) compares the target texture to kosher salt and beach sand. Anchor on that feel instead of a dial number, because identical numbers mean different things on different grinders.
A burr grinder matters more than any dial reading. Blade models smash beans into a mix of dust and chunks, and that uneven mix brews unevenly no matter what texture you aimed for.
A straightforward burr option like the Baratza Encore handles this kind of daily adjustment without fuss. Whatever you brew on, consistency comes first and precision second.
- Key Specifications:
- Steel conical burrs
- 40 stepped grind settings
- 8 oz bean hopper
Your Dripper Sets Your Exact Setting
Cone-shaped drippers want a medium-fine grind, while flat-bottom brewers prefer plain medium: your specific dripper decides the landing spot.
The Hario V60 has one large drain hole, so water escapes fast. A finer grind packs the coffee bed together and builds the resistance that keeps water in contact long enough to extract evenly.
- Key Specifications:
- Cone shape with one large drain hole
- Spiral ribs that lift the filter off the wall
- Available in plastic, glass, and ceramic bodies
The Kalita Wave takes the opposite approach with a flat floor and three small holes. Those holes supply their own flow resistance, so a plain medium grind drains evenly without stalling.
- Key Specifications:
- Flat-bottom brewing bed
- Three small drain holes
- Wave-shaped paper filters that hold grounds off the walls
The Chemex uses thicker bonded paper than most pour-over systems, which holds water back a touch longer. Grinding medium-coarse to medium compensates for that slow-draining filter.
- Key Specifications:
- Glass hourglass carafe
- Bonded square paper filters, thicker than standard circles
- Wood collar with leather tie
Use the table below to choose a starting grind for your specific dripper.
| Dripper | Bottom Shape | Starting Grind | Texture to Aim For |
| Hario V60 | Cone | Medium-fine | Kosher salt |
| Origami | Cone | Medium-fine | Kosher salt |
| Kalita Wave | Flat bottom | Medium | Rough sand |
| Chemex | Cone, thick bonded filter | Medium-coarse to medium | Coarse sand |
Treat each row as a starting point, not a final destination. The flavor of the cup tells you where to go from there.
Troubleshooting the Grind by Taste
Sour, salty, or hollow flavors can indicate an under-extracted brew; bitter, dry, or astringent flavors can indicate over-extraction.
Barista Hustle’s troubleshooting framework pairs those signs with fixes: grind finer for the sour camp, grind coarser for the bitter camp. Drain time usually confirms the same story.
Drawdown, meaning how long water takes to leave the bed after your final pour, should fall somewhere between about 2:30 and 4:00. Water racing through well under that window usually points to a grind that is too coarse, while a crawl toward the high end usually points to one that is too fine.
Change one thing at a time, starting with the grind. Strength lives in your dose and water, while extraction lives in grind size, so a bigger scoop rarely rescues a sour cup.
The Specialty Coffee Association’s Golden Cup standards describe balanced brews as falling into an 18-22% extraction yield window. Your tongue performs the at-home version of that measurement, and grind size is the main control for moving toward it.
Water temperature and ratio work alongside grind, but save those experiments for later. Lock the grind first so every brew gives you readable information.
If you jump between brewers, transfer nothing but technique: espresso routines want a much finer result than this, and a drip machine sits a step coarser. We cover those targets separately in grinding medium roast for espresso and dialing in medium roast for a drip machine.
Why Medium Roast Gives You Extra Room
Roast level changes how easily coffee dissolves, and medium roast sits right where pour-over likes to work.
Light roasts hold their structure tightly and often need a finer grind to give up their sweetness. Darker beans turn brittle and shed fine dust called fines, which over-extract and turn a cup harsh.
Medium roast splits the difference in both directions, which is why it behaves so steadily across brewers. In The World Atlas of Coffee (2018), James Hoffmann writes that medium roasts offer the widest margin for error in pour-over brewing.
One thing grind size cannot rescue is stale coffee. Aromas fade over weeks, so pair this grind guide with knowing how fresh your beans should be for pour-over.
Middle of the road wins: start medium-fine, with grains around kosher-salt size, matched to your dripper’s row in the table above. Brew one cup, taste it, and step the grind one notch finer or coarser to answer what the cup tells you.
