Indonesia introduced Arabica coffee and began to grow it during the Dutch colonial period in the 18th century, until it became the top coffee producer in the world in modern times, mainly in Sumatra, Java and Sulawesi.

The beans are named after the Batak people who grow coffee beans on the banks of Lake Toba in northern Sumatra and are crowned with Blue because of the blue-green appearance of the raw beans. Lake Toba is the hinterland of the world's largest volcanic lake. Buue Batak is mainly supplied by about 3500 small farmers around the Lindong producing area, producing about 300kg of coffee beans per person per year. This area is about 1550 to 1650 meters above sea level, the terrain is gentle, most of the planting environment is shaded, and the soil is fertile. Coffee production in this area is carried out by hand, from weeding and fertilization, picking ripe coffee cherries to peeling. The wet pods are fermented for 10-12 hours, and then the pectin and floating matter are removed manually before being washed and dried. This unique semi-washing method in Indonesia is called Giling Basah by local people, which is the traditional wet stripping method (wet-hulled) of the local Bhatta Croat.

After semi-washing treatment, farmers will sell them directly in the local market or send them to nearby concentration stations, and the raw beans with shells bought by the purchasers will be exposed again according to the situation, until it is confirmed that the water content is reduced to 12-13%. It is selected by hand according to size and weight and ready for export.
