Grind your Kenyan coffee medium-fine to medium for most single-serve brewing, about the texture of table salt. That single starting point works for pour-over cones, AeroPress, and single-cup drip machines, with small adjustments for each.
If your single-serve brewer is a paper-filter pour-over like a Hario V60 01 or Kalita 155, start at medium-fine. The Coffee Chronicler’s grind chart recommends roughly 550 to 750 microns for single-cup pour-over cones, which Asser Christensen describes as coarser than table salt and similar to granulated sugar. On a Comandante C40 hand grinder, that lands around 18 to 22 clicks; on a Baratza Encore, settings 14 through 16 are the practical equivalents.
The Grind Chart by Single-Serve Method
Your exact brewer matters more than the fact that your coffee is Kenyan. Blue Bottle Coffee’s brewing guidance and Starbucks’ consumer grind charts agree on the same core principle: match the grind to the method, then adjust by taste.
Use the table below to pick your starting grind setting before your first brew.
| Single-Serve Method | Starting Grind | Particle Size (Microns) | Texture Reference | Comandante C40 | Baratza Encore |
|---|---|---|---|---|---|
| Pour-over cone (V60 01, Kalita 155, Origami) | Medium-fine to medium | 550 to 750 | Coarser than table salt | 18 to 22 clicks | Setting 14 to 16 |
| AeroPress (standard 1-cup, 1.5 to 2 min) | Fine to medium-fine | 400 to 600 | Slightly finer than table salt | 13 to 17 clicks | Setting 10 to 13 |
| Reusable K-Cup pod | Medium | 700 to 850 | Coarse sand / kosher salt | 22 to 26 clicks | Setting 18 to 20 |
| Immersion-drip hybrid (Clever Dripper, Hario Switch) | Medium | 650 to 800 | Sea salt / standard sand | 20 to 24 clicks | Setting 16 to 18 |
All micron ranges and click settings above come from The Coffee Chronicler’s grind size chart. Treat them as starting points, not fixed rules.
Why Kenyan Coffee Needs Slightly Different Treatment
Kenyan coffee does not need a special grind just because it is Kenyan. All three sources agree the brewer drives grind choice, but Kenya’s bean structure adds one wrinkle worth knowing.
Sweet Maria’s green coffee library notes that Kenyan lots, mostly SL-28 and SL-34 cultivars grown in volcanic soil around Mount Kenya and the Aberdares at roughly 1,700 to 2,000 meters, have exceptional cellular density and prominent phosphoric acidity. That density changes how the beans break in a grinder.
Barista Hustle’s coffee science education explains that denser beans, typically grown at higher altitudes and roasted lighter, are harder and more brittle. When crushed between burrs, they shatter into a higher volume of fine particles compared to softer, low-grown beans.
Those excess fines migrate toward the filter paper in pour-over brewing. The result is increased flow resistance and a higher risk of stalling and channeling.
This is the practical takeaway: if you already brew other single-origin coffees, start your Kenyan grind one or two clicks coarser than your usual pour-over setting. Dense beans produce more dust, so a slightly coarser starting point keeps the water flowing evenly.
Gear Notes: Burrs Matter for Dense Beans
A blade grinder will pulverize dense Kenyan beans unevenly, so a burr grinder is the right tool here. Conical or flat steel burrs keep the particle spread narrow, which matters more with high-fines coffees than with softer beans.
If you are shopping for a dedicated single-cup hand grinder, the Comandante C40 offers the click-range precision described in the table above.
- Burr type: Stainless steel conical burrs
- Adjustment: Click-based stepped settings
- Capacity: Single-dose friendly, roughly 30 g
For an electric option at home, the Baratza Encore covers the 10-to-20 setting range this article references.
- Burr type: Hardened steel conical burrs
- Adjustment: 40 stepped settings
- Dosing: Front-mounted hopper with grounds bin
Whichever grinder you use, grind immediately before brewing. Freshly ground coffee gives you the most accurate taste feedback when dialing in.
Troubleshooting: Reading Your Cup and Fixing It
Taste is the best adjustment signal, according to brewing guides from The Coffee Compass. Use these patterns to diagnose and correct your grind.
If the cup tastes sour, sharp, or hollow, that can indicate under-extraction. Grind one step finer, or raise your water temperature slightly.
If the cup tastes bitter, astringent, or muddy, that can indicate over-extraction. Grind one to two steps coarser so fewer fines accumulate in the filter bed.
If the filter stalls mid-brew or draindown takes far too long, go slightly coarser. With dense Kenyan beans, a stalled bed usually means fines have clogged the paper.
One mistake to avoid: reaching for a bigger dose when the actual problem is grind size. Many people try to fix a flat, muted cup by adding more coffee, when a finer grind or a tighter ratio would address it directly.
Muted fruit flavors that should jump out of a Kenyan lot often respond to shortening the ratio rather than changing anything else. Tightening from 1:16.5 toward 1:15 increases flavor concentration.
Curious whether your beans themselves are the issue? Our guide on choosing the right Kenyan coffee for single-serve covers what to look for before you ever touch the grinder.
Water and Ratio Context
Grind size does not work alone, so two quick settings complete the picture. Everything else about extraction belongs to its own discussion.
Water temperature also shifts the cup with dense beans. Sweet Maria’s recommends hot water, in the range of roughly 93 to 96 degrees Celsius (200 to 205 degrees Fahrenheit), to extract the complex sugars and balance Kenyan coffees’ natural acidity.
A brew ratio of 1:15 to 1:16.5 works well for a single cup: 15 grams of coffee to roughly 225 to 245 grams of water. A small scale makes this repeatable from brew to brew.
An affordable option like the espresso coffee scale with 0.1 g resolution removes the guesswork entirely.
- Resolution: 0.1 gram increments
- Reading: Both grams and ounces
- Feature: Built-in timer for pour-over timing
Keep agitation moderate, too. Excessive stirring or swirling pushes fines into the paper pores and causes the clogging this article has warned about.
Freshness Affects Your Dial-In Too
Stale beans change how a grind behaves, sometimes dramatically. Older coffee loses internal pressure and resists even extraction.
For the full window on bag care, see our piece on how fresh Kenyan coffee should be for single-serve. Roast level matters as well; our guide on the best roast level for Kenyan single-serve coffee pairs nicely with the density notes above.
The Bottom Line
Start your Kenyan single-serve grind at medium-fine to medium, roughly the texture of table salt, then lean one or two clicks coarser to offset the extra fines that dense high-altitude beans produce.

Your next action: pick your brewer from the chart above, set your grinder, brew one cup, and taste. Then adjust one variable at a time until the blackcurrant brightness comes through clean.
