BACKGROUND: This Sumatra Longberry microlot is from the Wahana Estate and as the name suggests, is a long and thin shaped bean varietal. It is said to have originated in Ethiopia due to a similarity to a varietal called Longberry Harrar: and it is also originally known to grow only in Aceh. Wahana Estate has been credited with bringing this varietal to the Lake Toba area of Sumatra as one of their experimental varieties.
Unusually for Indonesia, much of Wahana’s coﬀee is fully-washed – using the estate’s new wet milling facility. This was installed in 2009 and can process an impressive 25 metric tonnes of red cherries per hour. The cherries are picked only when fully ripe and are then sorted and graded by hand when they reach the dry mill, before being pulped. The coﬀee is then fully fermented until the mucilage becomes removable, is fully washed and is then dried on the mill’s extensive patios to 11% humidity.
