West Java vs North Sumatra
Indonesia’s two estate regions, both laid out in the colonial period on assamica stock after early experiments with Chinese seed failed. They differ in altitude, in volcanic setting and in what has happened to the estates since.

What is being compared
Point by point
| Aspect | West Java | North Sumatra |
|---|---|---|
| Setting | The Priangan highlands south of Bandung, on the flanks of active volcanoes. | The plateau country around Lake Toba, in Simalungun and neighbouring districts. |
| Elevation | 700 to 1,800 metres. | 700 to 1,500 metres. |
| How planting began | Dutch planters concentrated tea here once assamica proved suited to the uplands. | Planted in the colonial period alongside rubber and tobacco. |
| Estate scale | Large, and still the centre of Indonesian production. | Large and long-established. |
| Product | Black tea mainly, with green tea for the domestic market. | Black tea, largely for export and blending. |
| How it reaches drinkers | Mostly unbranded, into blends. | Mostly unbranded, into blends. |
The short answer
Indonesia is a large producer with almost no consumer-facing identity, and both regions illustrate the same mechanism: colonial estates built to supply a blending market never developed the naming and grading conventions that let a region be bought by name. The tea is not the obstacle.
