Central Highlands

What makes it different

The Central Highlands around Buôn Ma Thuột are the engine room of world coffee. This is overwhelmingly robusta, grown at low altitude on deep red basalt soil, and it is the reason instant coffee and supermarket blends cost what they do.

Compared with Cerrado Mineiro

The two giants of world coffee, and both are volume origins — but Brazil grows arabica and Vietnam grows robusta, which is a species-level difference rather than a stylistic one. Cerrado gives you chocolate and nut with soft acidity; Vietnam gives you bitterness, body and caffeine. Between them they set the world price.

How this place shapes the taste

1. Variety: Overwhelmingly robusta (Coffea canephora), with limited arabica at higher elevation

   The decisive factor. Robusta is a different species: harder, hardier, roughly twice the caffeine, far more bitter and far less aromatic. Almost everything about the cup follows from that, not from the place.

2. Altitude: 500–900 m — low, and deliberately so

   Robusta thrives where arabica struggles, and low elevation with high heat suits it. Judging this coffee by the altitude scale on this page is a category error: it is not trying to be bright.

3. Soil: Deep red basalt soils, exceptionally fertile

   Among the best coffee soils anywhere, and a large part of why yields per hectare here are the highest in the world. Fertility here translates into volume rather than complexity.

4. Rain & humidity: A pronounced wet season and heavy dry-season irrigation

   The dry season requires large-scale irrigation, which has drawn down groundwater significantly. This is the origin where the environmental cost of the crop is most visible.

5. Processing: Predominantly natural, sun-dried, at very large scale

   Efficient and inexpensive, and where quality is usually lost — mixed ripeness and rapid drying suit volume rather than flavour. Careful Vietnamese robusta exists and tastes considerably better than its reputation.

The expansion, and the price crash

Following economic reforms in the late 1980s, Vietnam expanded coffee planting in the Central Highlands at extraordinary speed, backed by state support and internal migration into the region. Production multiplied many times over within about fifteen years and Vietnam became the world's second-largest producer. The consequence was global: the resulting oversupply contributed to a collapse in world coffee prices around the turn of the millennium, pushing growers from Central America to East Africa below the cost of production. It is the clearest demonstration in modern coffee that what happens in one origin is felt in all of them.

Brewing it

Made for the Vietnamese phin filter: dark roast, coarse grind, slow drip over condensed milk and ice. In espresso it contributes crema and body, which is why it is in more blends than anyone admits. Do not judge it as a filter coffee — it was never trying to be one.
