Description of grindness and Flavor of Indonesian Java Coffee introduction to processing methods of high-quality coffee beans

Java produces only a small amount of Arabica beans, most of which were imported from Africa after the rust disaster. This kind of coffee has a strong bitter taste after roasting, but its flavor is extremely light. Although it has low acidity and delicate taste, it is rarely used for direct drinking. It is often used to mix mixed coffee, or to make instant coffee in Asian countries that produce coffee. Indonesia is a very noteworthy one. Indonesia is an island country in the Indian Ocean, the islands are distributed on both sides of the equatorial line, of which three islands: Java, Sumatra and Sulawesi produce the world's important coffee. In the mid-17th century, the Dutch brought coffee trees to Ceylon (Sri Lanka) and Java, Indonesia. In the 18th century, Indonesia became a major producer of coffee, and almost all of its high-quality Arabica coffee was supplied to Europe. But by the 19th century, coffee rust, which appeared in Ceylon in 1869, also affected Indonesia. By 1877, most of the coffee fields on the Indonesian islands had been damaged by rust, and the Dutch had to import other coffee varieties from Africa, namely Romsda coffee. It is more resistant to diseases and insect pests, but its quality is inferior. About 90% of Indonesian coffee is Romda beans, about 6.8 million bags a year, and less than 10% of beans are Arabica coffee. Sumatra is the largest producer of Indonesian coffee. Well-known coffee-growing areas are mainly concentrated in the northern mountains, including Aceh in the northernmost province of Aceh and Sumatera Utara in North Sumatra. Including the well-known Mantenin Mandheling, Lin Dong Lintong, Jiayushan Gayo Mountain.

The name of Mandheling coffee is said to come from the local people, mandailing. The producing areas mostly point to the mountains in the north of Lake dopa, and the specific producing areas need to be verified.

Lintong coffee comes from the foothills around Lake Lake Toba in North Sumatra, Sumatra's largest volcanic lake, and its name comes from the small town called lintong in the southwest of Lake dopa.

Gayo mountain Coffee from Takengon, Takangong, Aceh Province and the mountains around Lake Lake Tawar.

Medan Medan and Padang Padang are important cities involved in coffee. They are the capital of North Sumatra and West Sumatra respectively, and they are also the most densely populated areas in Sumatra. The former is an important distribution center for Sumatra coffee exports, while the latter is also a well-known coffee production around, such as Ankola.

Coffee from Sumatra includes Arabica and Robusta, which is usually grown at high altitudes in the mountains, while robusta is grown in the lowlands. Coffee treatment is famous for the traditional "wet planing", Giling Basah,wet-hulled, and the special treatment is partly due to the local humid climate.
