, at an altitude of more than 1,400 meters. The coffee is primarily grown on large estates that were built by the Dutch in the 18th century. The five largest estates are Blawan (also spelled Belawan or Blauan), Jampit (or Djampit), Pancoer (or Pancur), Kayumas and Tugosari, and they cover more than 4,000 hectares

These estates transport ripe cherries quickly to their mills after harvest. The pulp is then fermented and washed off, using the wet process. This results in coffee with good, heavy body and a sweet overall impression. They are sometimes rustic in their flavor profiles, but display a lasting finish. At their best, they are smooth and supple and sometimes have a subtle herbaceous note in the aftertaste.

This coffee is prized as one component in the traditional "Mocha Java" blend, which pairs coffee from Yemen and Java.
Some estates age a portion of their coffee for up to three years. During this time, the coffee is "monsooned", by exposing it to warm, moist air during the rainy season. As they age, the beans turn from green to light brown, and the flavor gains strength while losing acidity. These aged coffees are called Old Government, Old Brown or Old Java.
