Grind your Arabica medium-fine for pour-over, somewhere between table salt and slightly coarser than drip coffee. That single starting point, recommended by specialty roasters like Blue Bottle Coffee and Stumptown Coffee Roasters, works for almost every Arabica you will brew. Then you fine-tune by taste and by how fast the water drains.
Here is the short version: start medium-fine, brew once, taste the cup, and watch the drawdown. If the coffee tastes sour or the water runs through too fast, grind finer. If it tastes bitter or the brew stalls, grind coarser. That loop is the whole skill, and this guide walks you through it step by step.
The Short Answer: Medium-Fine for Most Arabica Pour-Over
Medium-fine is the recommended starting grind for pour-over brewing, according to Blue Bottle Coffee’s brew guides. Stumptown Coffee Roasters and Counter Culture Coffee both support the same starting range for pour-over methods. Think of a texture between granulated table salt and slightly coarser than a standard drip grind.
One important note up front: “Arabica” by itself does not lock in one grind size. Your brewer shape, roast level, and bean freshness all matter as much as the species. A light-roast Arabica usually needs a finer grind than a darker roast to extract properly.
A good single-cup pour-over usually finishes somewhere between 2:30 and 4:00 minutes total, depending on your brewer, dose, and recipe. Use that window as a sanity check, not a strict rule.
Starting Grind by Brewer Type
Not all pour-over drippers behave the same, and cone, flat-bottom, and thick-filter brewers each favor a slightly different grind. The shape of the bed and the thickness of the filter change how water flows through the coffee.
Use the table below to pick your starting grind before your first brew.
| Dripper | Starting Grind | Texture Reference | Typical Brew Time |
| Hario V60 and cone drippers | Medium-fine | Like table salt | 2:30 to 3:30 |
| Chemex (thick filters) | Medium to medium-coarse | Between table salt and kosher salt | 3:00 to 4:30 |
| Kalita Wave and flat-bottom drippers | Medium | Like coarse sand | 3:00 to 4:00 |
For a cone brewer, the Hario V60 is the classic choice and a cheap way to get into precise pour-over brewing. Flat-bottom fans often reach for the Kalita Wave stainless dripper, which forgives uneven pours a little more easily.
How Roast Level Changes Your Grind
Roast level is the biggest Arabica-specific variable for grind size, and it interacts directly with how the beans shatter in your grinder. In The World Atlas of Coffee, James Hoffmann explains that light-roasted, dense Arabica coffees break down differently than dark roasts. They demand a finer setting and hotter water to release their complex, acidic compounds.
Here is the practical pattern:
- Light roast: grind slightly finer and use hotter water, because dense light roasts extract slowly.
- Medium roast: stick with the medium-fine baseline.
- Dark roast: grind a touch coarser and ease off the water temperature, because brittle dark roasts extract fast and can turn bitter and astringent.
If you are still deciding which roast suits pour-over in the first place, our guide to the best roast for Arabica pour-over breaks that down separately. Grind size is only half of that equation.
How to Fix a Bad Cup: The Dial-In Loop
Every source on this topic, from Blue Bottle to Counter Culture, teaches the same troubleshooting logic. Grind size controls two things at once: how much surface area the water touches, and how fast the water can pass through the bed. A finer grind increases extraction and slows the flow, and a coarser grind does the opposite.
Use this diagnostic loop after every brew:
- Brew once at your starting grind and note the total time.
- Taste the cup and watch the drawdown.
- Adjust one step at a time, then brew again.
Sour, sharp, or hollow cup with a fast drawdown can indicate under-extraction. The water moved through too quickly and pulled mostly the bright acids. Fix it by grinding finer.
Bitter, astringent, or dry cup with a stalled brew can indicate over-extraction. The water sat too long and pulled out harsh compounds. Fix it by grinding coarser.
Balanced sweetness, clean acidity, and a clean finish means you are close to the optimum extraction window. The Specialty Coffee Association defines that target as 18 to 22 percent extraction yield in filter brewing. Hold your setting and just repeat the brew.
Why Arabica Itself Is Not the Main Variable
Here is the insight most guides miss: the species on the bag matters far less than what happened after harvest. Arabica covers everything from a dense, high-grown Ethiopian to a soft, lowland commodity bean, and those two beans need different settings on the same grinder.
So instead of searching for “the Arabica grind,” read your specific bag. A washed, light-roasted, high-altitude Arabica behaves one way, and a natural-processed dark roast behaves another. Processing method matters too: natural and honey-processed coffees can generate more fine particles that slow your drawdown, so a slightly coarser setting often keeps the flow steady.
Bean age is the other quiet variable. Fresh beans off-gas carbon dioxide and can cause bloom issues and uneven extraction, so if your grind seems right but the cup is off, check how fresh your Arabica should be for pour-over before you blame the grinder.
Getting the Grind Right at Home
A burr grinder, not a blade grinder, is what makes these settings repeatable. Blade grinders shatter beans into uneven sizes, which means you get under-extracted and over-extracted particles in the same cup, and no amount of dialing-in fixes that. A Baratza Encore is the entry-level burr grinder most home brewers start with, and it has enough adjustment steps for pour-over work.
If you brew by hand and want fewer retained grounds between doses, a single-dose hand grinder like the Comandante C40 offers very fine control between settings. Whatever grinder you own, change only one setting per brew. Two changes at once mean you no longer know which one fixed the cup.
One last note on method boundaries: espresso needs a much finer grind and cold brew a much coarser one, so a pour-over setting will not transfer between them. If you also pull shots, our guide to grinding Arabica for espresso covers that separately.
Wrapping Up
Grind your Arabica medium-fine for pour-over, roughly the texture of table salt, and expect a total brew time between 2:30 and 4:00 minutes. Then let your taste buds do the rest: sour means finer, bitter means coarser, and one small adjustment per brew gets you dialed in within a few cups.
