Indonesia's territory from west to east, more than 17,000 large and small islands, emerald scattered on the earth's equator line. Indonesian coffee is mainly produced in Sumatra, Java, Sulawesi and Bali, among which Sumatra is the most famous "Mantenin".

MANDHELING Coffee is Indonesia's most representative coffee bean, and anyone who likes coffee knows MANDHELING. The Mantenin are actually a minority group living in the northern highlands of Sumatra Island. The origin of the name of Mantenin Coffee is related to the history of Japanese aggression. During the Japanese occupation of Indonesia in World War II, a Japanese soldier drank excellent coffee in a cafe. He asked the owner the name of the coffee. The owner mistook him for asking where you were from and replied: Mantenin. When Japanese soldiers returned home after the war, they recalled drinking "Mantenin" in Indonesia. So I asked someone to ship 15 tons from Indonesia to Japan, which was very popular. Mantenen's name spread like this.

Mantenin comes mainly from two regions:

One is Aceh, which contains Lake Tawer, and Gayo Mountain.

The other is North Sumatra, a plateau surrounded by Lake Toba and LingTong.

Mantenen's unique wet planing method

Wet Hulling is the traditional Indonesian coffee processing method. In its name alone, wet planing is similar to wet processing (washing), however, the cup flavor of the two treatments is quite different, and the coffee processed by wet planing is usually rich and strong, and the personality is very distinct.

the step of that wet planing proces method are as follows: 1. removing peel and pulp, and reserving parchment and mucous membrane; 2. fermenting in a pool; 3. washing away mucous membrane; 4. drying parchment in the sun for 2-3 days until the moisture content is 20-24%; 5. planing parchment

Dry the beans to a moisture content of 12-13%.

Indonesia's tradition of wet planing begins with the local weather. Indonesia's annual humidity is between 70 and 90%, typhoons are frequent, and in some areas, annual rainfall can reach as much as 2,000 mm. How does Indonesia overcome such harsh weather conditions to produce rich, full-bodied mantnings, given that green beans are most afraid of rain? That is to rely on wet planing method.

In tropical climates, coffee takes an average of two to three weeks to dry. In Indonesia's humid climate, dry coffee is a big problem. Coffee must take a longer time to dry, during which time the coffee still maintains a high humidity, which makes it easier for bacteria to penetrate the green coffee beans.

In the ordinary washing process, the drying process is carried out with parchment paper, so as to protect the raw beans from external damage to a certain extent. However, we can note that wet planing removes parchment for the final drying step, so that sunlight hits the green beans directly on the surface, drying the beans quickly, two to three times faster than washing.
