| Metric | Sumatra | Kenya |
|---|---|---|
| Summary | Heavy, low-acid, and earthy: cedar, cocoa, and forest-floor notes. Pick this only if you want a deep, savory cup rather than fruit. | Punchy and juicy: blackcurrant, grapefruit, and a syrupy sweetness. Not a gentle starter, but vivid if you like bright fruit. |
| Tasting notes | cedar, dark cocoa, fresh pipe tobacco, damp forest, licorice | blackcurrant, grapefruit, tomato leaf, brown sugar, black tea |
| Who grows it | Smallholders selling parchment to collectors and mills in Aceh and North Sumatra. | Smallholder cooperatives delivering to named factories (wet mills). |
| Producers in detail | Lots are often blended at a mill that buys from many gardens. Traceable Gayo or Lintong bags may name a cooperative. The farm-life image is raking drying seed on concrete, not a Kenyan washing channel. Sorting by hand after hulling is still part of the cup quality. | A typical Nyeri or Kirinyaga lot is hundreds of families, each with a small plot, delivering cherry to a factory owned by a Farmer Cooperative Society. Factory names (Gichathaini, Gititu, Karimikui) are the producer credit. Estates exist around Kiambu; central-highland sparkle more often comes from the co-op system. |
| Terroir | Tropical rainforest humidity, volcanic lakes (Toba) and highland basins (Gayo). Shade, clay, and wet harvest weather make slow, fully dry naturals risky - wet-hulling is terroir as method. Cedar and cocoa are the landscape in the cup. | Volcanic slopes of Mount Kenya: red nitisols, high altitude, two rainy seasons. The coffee belt sits under forest reserve. That geology plus the double-wash protocol is why Kenya does not taste like a washed Colombia even when both are “washed Arabica.” |
| Process | Often wet-hulled (giling basah), typical of Sumatra. | Typically double-washed, then soaked, then dried on raised beds. |
| Process in detail | Cherry is pulped, briefly fermented, and dried only until the parchment is still damp. Hulling that wet parchment - giling basah - exposes a swollen seed that finishes drying on patios in humid air. The result is low acidity, heavy body, and cedar-herb notes. It is not a washed Ethiopia that went wrong; it is a different process chosen for a wet climate. | Kenya’s factories pulp cherry, ferment, wash in channels that also grade by density, then soak parchment in clean water for another 12–24 hours. That second soak is the “Kenya wash” - it strips residual pulp and is why the cup is so clean and loud. AA, AB, and PB are screen sizes, not farms. |

| Bag cue | Look for Sumatra or Mandheling, earthy, low acid, dark cocoa. Gayo if Aceh is named. | Look for Kenya, Nyeri or Kirinyaga, blackcurrant, AA if listed. |
| Cafe order | A Sumatra or Mandheling, the earthy low-acid one - French press or espresso, not a light pour-over. | A Kenya, Nyeri or Kirinyaga, light roast, black - the blackcurrant one. |
| Milk | Black, Dairy, Oat | Black |
| Species | arabica | arabica |
| Altitude (light) | Mid-highland - often 1,100–1,600m | High-grown - often 1,600–2,000m |
| Altitude (detail) | Gayo highlands in Aceh and the Lintong / Mandheling areas around Lake Toba commonly sit 1,200–1,600m. That is respectable altitude, but wet-hulling and humidity mute the sparkle you would expect from the same elevation in Kenya. | Nyeri and Kirinyaga lots typically sit 1,600–2,000m on volcanic red clay. Mount Kenya and the Aberdares shape rainfall into two wet seasons and two harvests. Cool nights plus volcanic soil are the structural reason Kenyan acidity reads as currant rather than simple lemon. |
| Varieties | Tim Tim, Ateng, Onan Ganjang, Gayo selections (when labeled) | SL28, SL34; Batian and Ruiru 11 on newer lots |
| Harvest | Long, staggered harvests; many regions pick across much of the year, with peaks after rains. | Main crop roughly October–December; fly crop around April–June. |
| Brew rec | French press or espresso. A paper pour-over can taste too thin. Medium-dark roast is traditional; very light roast can taste vegetal. | Pour-over, plenty of water (1:16 or 1:17) so currant stays juicy instead of sharp. Light roast only. |
