TEMANGGUNG NATURAL ROBUSTA COFFEE — CENTRAL JAVA, INDONESIA

Temanggung became a Robusta-growing region out of necessity. A leaf rust epidemic in the late 19th century devastated Arabica plantations across Java, prompting farmers to switch to the more disease-resistant Robusta variety. Today, coffee farms on the slopes of Mount Sindoro and Mount Sumbing produce Temanggung Robusta, known for its smoother character compared to lowland Robusta, with nutty and chocolate notes and a bitterness that is never overly harsh.

This lot is Grade 1 Natural Robusta. The coffee cherries are dried whole before the beans are sorted and packed. For cafés in Java looking for an espresso base sourced from their own region, or roasters seeking a sweeter Robusta profile for their blends, Temanggung delivers on both fronts.

TRIPLE PICK QUALITY ASSURANCE

Why Is Our Green Coffee More Honestly Graded?

Most marketplace sellers claim Grade 1 quality based on just one rough machine-sorting pass. At Coffest Roastery, we apply three stages of physical sorting:

1. Suton Machine: Removes foreign materials such as stones, twigs, dust, broken beans, and residual silver skin that make it through the earlier processing stages.

2. Optical Sorting Machine (SORTEX): Modern optical sensor technology that ejects black beans, sour beans, and beans with defects caused by insect damage.

3. Hand Sorting (Manual Pick): The final manual inspection by our expert team to remove fungus-damaged beans and ensure that defects are reduced to nearly 0%.

The drying process uses indirect sunlight through a greenhouse effect to help preserve the coffee's optimal flavor potential.
