| Metric | Sumatra | Uganda (Mount Elgon) |
|---|---|---|
| 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. | High volcanic slopes and East African varieties can give a sweet, lively cup. Look for Elgon on the bag, not generic robusta Uganda. |
| Tasting notes | cedar, dark cocoa, fresh pipe tobacco, damp forest, licorice | stone fruit, floral honey, bergamot, brown sugar, black tea |
| Who grows it | Smallholders selling parchment to collectors and mills in Aceh and North Sumatra. | Bugisu smallholders and wet mills on Elgon, including stations near Sipi Falls. |
| 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. | Historically the Bugisu Cooperative Union organized much of the Arabica. Today private mills (for example around Kapchorwa / Sipi) buy cherry from smallholders on the volcano’s farms. The producer picture is East African: family plots, washed mill, raised beds - closer to Kenya than to Brazilian estates. |
| 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. | Elgon’s volcanic slopes, high rainfall, and montane forest. Sipi Falls is the landscape landmark. Soils and altitude overlap Kenya’s, which is why florals and stone fruit appear - process and variety complete the resemblance. |
| Process | Often wet-hulled (giling basah), typical of Sumatra. | Specialty lots are often washed at a wet mill. |
| 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. | Bugisu / Elgon Arabica is typically washed: cherry to a mill such as the stations around Sipi Falls, pulped, fermented, dried on raised beds. That is the same family of process as Kenya, without Kenya’s extra soak and AA screening culture. Naturals exist but washed is the bag to seek if you want floral-fruit clarity. |
| Brew tag | Filter or espresso | Filter |
| Bag cue | Look for Sumatra or Mandheling, earthy, low acid, dark cocoa. Gayo if Aceh is named. | Look for Uganda Mount Elgon, Arabica, high grown - not generic instant robusta. |
| Cafe order | A Sumatra or Mandheling, the earthy low-acid one - French press or espresso, not a light pour-over. | Uganda Mount Elgon, Arabica - not generic robusta. Light roast, black. |
| Milk | Black, Dairy, Oat | Black |
| Species | arabica | arabica |
| Altitude (light) | Mid-highland - often 1,100–1,600m | High (Elgon) - about 1,600–2,200m |
| 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. | Coffee on Elgon’s Ugandan slopes (Kapchorwa, Bududa, Sironko, Mbale) commonly grows 1,600–2,200m on volcanic soils. That is why this origin is listed separately from the robusta that still dominates Uganda’s export volume. |
| Varieties | Tim Tim, Ateng, Onan Ganjang, Gayo selections (when labeled) | SL14, SL28, Nyasaland (when labeled) |
| Harvest | Long, staggered harvests; many regions pick across much of the year, with peaks after rains. | Main harvest roughly October–February on many Elgon farms. |
| 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, light roast. Treat it like a quieter Kenya. Confirm Arabica / Elgon before brewing as espresso. |
