About This Coffee

This Robusta is grown on nutrient-rich volcanic slopes in Temanggung, Central Java, by smallholder farmers from the Jawa ethnic community. The region’s favorable growing conditions and generations of farming know-how are reflected in the lot’s large bean size and cup quality. 

Historically, Robusta was introduced to the region in the late 1800s following a leaf rust epidemic. Initially adopted as a survival crop, it gradually reshaped local coffee cultivation, turning Temanggung into one of Indonesia’s key Robusta-growing regions. 

Grown on fertile volcanic soils at elevations of around 800 to 1,100 meters above sea level, the coffee cherries mature more slowly, helping develop sweetness and bean density. As the region’s main cash crop, coffee also receives considerable attention from farmers, who typically handpick ripe cherries to maintain quality. The result is a clean, rounded cup with notes of chocolate, brown sugar and a touch of spice. 

Cultivation

The coffee is grown on small farms ranging from 0.5 to 1 hectare. Farmers in Temanggung use shade-grown agroforestry systems and often intercrop coffee with fruit trees. The primary variety is the Tugusari (Caneophora) clone, alongside several other local Robusta strains.

Harvest & Post-Harvest

Unlike many other coffee-growing regions in Indonesia, where Natural processing is more common, this lot is processed using the Pulped Natural method. Ripe cherries are selectively handpicked to ensure consistent quality. Cherries are carefully hand-sorted to ensure optimal quality. Selected cherries are pulped and sun-dried on patios before being sent to local processors for final milling. This process helps produce a balanced cup with pleasant acidity, prominent sweet fruit notes and a clean finish.

About Tugusari

Tugusari is a Robusta coffee clone associated with East Java, Indonesia and widely cultivated in several coffee-growing regions, including Temanggung in Central Java. It is known locally through several selections, including Tugusari Hijau and Tugusari Kuning. Research has identified promising productivity and cup quality among these selections, with some achieving Fine Robusta scores.

About BP 409

BP 409 is a Robusta clone originating from the BP 42 selection at Dampar Plantation, Indonesia. The variety is characterized by relatively large cherries, strong branches and dark green, glossy leaves. It demonstrates reasonable drought tolerance and some resistance to coffee berry borer and parasitic nematodes.

Coffee in Indonesia

Indonesia has a long coffee producing history, but recently their coffees have been overlooked by the specialty market. Thanks to our innovative and ever-expanding supply chain, we are proud to bring you high-quality coffees from many of Indonesia’s unique regions, accompanied by in-depth traceability information.

Indonesia is perhaps best known for its unique wet hulling process (giling basah). Though its exact origins are unclear, wet hulling most likely originated in Aceh during the late 1970s.

Wet hulling’s popularity can be attributed to producers’ need for prompt payments. It was also adopted specifically by many producers who lacked the drying infrastructure that was needed to shelter drying parchment from the high humidity and inconsistent rainfall typical in Sumatra. At higher elevations with constant humidity and unpredictable rainfall, drying can prove to be slow, risky and difficult.
