| Metric | Sumatra | Ethiopia (Yirgacheffe, washed) |
|---|---|---|
| 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. | A tea-like, floral cup: jasmine, bergamot, and a light body. Choose this if you want coffee that feels closer to a fragrant tea than to a dark roast. |
| Tasting notes | cedar, dark cocoa, fresh pipe tobacco, damp forest, licorice | jasmine, bergamot, lemon tea, peach blossom, honeyed finish |
| Who grows it | Smallholders selling parchment to collectors and mills in Aceh and North Sumatra. | Smallholders delivering cherry to a named washing station or cooperative. |
| 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 Yirgacheffe bag is rarely one farm. Hundreds of garden plots feed a station - Idido, Konga, Kochere, and similar names. The producer story is collective: families pick ripe red cherry, the station sorts and washes, the exporter lots by grade. When a bag lists a station, that is the traceability you actually have. |
| 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. | Gedeo sits in southern Ethiopia’s highlands: iron-rich red soils, shade, and a wet season that favors washed processing because cherry can move to a mill the day it is picked. The landscape is gardens and forest edge, not Brazilian estate rows. That density of wild and semi-wild Arabica is the terroir. |
| Process | Often wet-hulled (giling basah), typical of Sumatra. | Typically washed at a station, 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. | Smallholders pick cherry and deliver it the same day to a washing station. Pulping, fermentation, and a clean water wash strip fruit so landrace florals stay precise instead of jammy. Parchment dries on raised African beds for about two weeks. This is the opposite of a Hambela natural: same country, different process, different cup. |
| 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 Yirgacheffe or washed Ethiopia, jasmine or bergamot, light roast. |
| Cafe order | A Sumatra or Mandheling, the earthy low-acid one - French press or espresso, not a light pour-over. | A washed Yirgacheffe, light roast, black - jasmine or bergamot, no milk. |
| Milk | Black, Dairy, Oat | Black |
| Species | arabica | arabica |
| Altitude (light) | Mid-highland - often 1,100–1,600m | High-grown - often 1,800–2,200m |
| 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. | Gedeo zone lots labeled Yirgacheffe commonly grow between about 1,800 and 2,200 meters. Cool nights stretch ripening; the seed is dense, which is why light roasts still taste sweet instead of thin. |
| Varieties | Tim Tim, Ateng, Onan Ganjang, Gayo selections (when labeled) | Ethiopian landraces / heirloom (Kurume, Dega, Wolisho when named) |
| Harvest | Long, staggered harvests; many regions pick across much of the year, with peaks after rains. | Main harvest roughly October–January, depending on woreda and altitude. |
| 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, 15–16:1, medium-fine, just-off-boil. Skip milk. AeroPress with a paper filter also keeps the florals. |
