FLORES

Flores is a small island about 320km (200miles) east of Bali and is located in one of the Indonesian archipelago. As a latecomer to the coffee industry, it has also developed a good reputation for growing coffee. In the past, it was common to see that a large part of Flores's coffee was sold domestically or mixed with other coffee exports, rarely sold directly in the name of "Flores Coffee". There are active and dormant volcanoes on the island, and the mixture of Bajawa volcanoes has a great positive impact on the main planting areas. In terms of coffee processing, the semi-washing process is the most common treatment in the region, and some coffee beans are still produced by full-water treatment.

BALI

Coffee arrived late in Bali and was originally grown on the Kintamani plateau. Coffee production was deeply affected by the eruption of Gunung Agung in 1963, killing more than 20, 000 people and extensively destroying the eastern part of Bali. In the late 1970s and early 1980s, the government distributed Arabica bean seedlings to boost coffee production, but some thought the effect was limited because about 80% of the island's production today is robusta beans. Although tourism provides the largest income, agriculture employs the most people on the island, while Japan used to be the biggest buyer.

Indonecia Indonesia

Population: 237424000

In Indonesia, coffee beans slowly grew from Java to neighboring islands, first to Sulawesi in 1750, but not to northern Indonesia at that time. Until 1888, when planting began around Lake Lake Toba, it eventually spread to Lake Lake Tawar in the Gayo region in 1924.

SUMATRA

Sumatra has three main growing areas: the northern part of Aceh, the slightly southward area around Lake Lake Toba, and the recent rise of islands near Mangkuraja. It may also be traced back to smaller areas of Takengon, Bener Mariah, Lintong, Sidikalang, Dolok Sanggul, and Seribu Dolok, which surrounds Lake Doba in Aceh. In the past, the coffee beans sold in this area were called "Sumatra Mantenin", but in fact there was no place name called Mantenin, which came from the ethnic names of the local islanders. Manning is usually divided into grades, classified as Grade1 or Grade2. There is no doubt that the grading method is to use the cup to test the quality rather than the raw bean itself. But I still have doubts about recommending Grade1 because the rating seems to be overdone. It is strange to divide different varieties into different batches, so most Sumatran coffee beans are mixed with unknown varieties. Sumatran coffee beans are exported through the port of Medan, but stagnated in the port for too long before export, hot and humid climate factors will not be conducive to the quality of coffee beans.

Altitude: 1100-1300m in Aceh, 1100-1600m in Lake Doba, 1100-1300m in Mangkuraja

Harvest: September-December

Varieties: Typica (including Bergandal, Sidikalang, Djember), Timtim, Ateng, Onan Gajang

JAVA

In Indonesia, this area inherits Dutch colonization and habits, so there are more large coffee estates. The four main coffee fields, covering 4000 hectares, were formerly government estates. At that time, the coffee beans in this region enjoyed a first-class reputation, although I believe that not long ago, a large number of formula beans have been replaced by other coffee beans "Mocha-Java". Java coffee beans have been high for a long time, but there have been significant price reductions in the 20th century. The planting area covers the east side of Java around the Ijan volcano, as well as the west side.

Altitude: 900-1800m

Harvest: September-September

SULAWESI

Even though seven major estates supply about 5% of Sulawesi's production, local production is dominated by the supply of small farmers. Most Arabica beans are grown high around Tana Toraja, while Kalosi in the south becomes a brand, and there are two less well-known areas: Gowa, west of Mamasa and south of Kalosi. A small number of particularly interesting coffee beans are washed with water, which is worth thinking about, and it is highly recommended to try it when you have the opportunity. Semi-washing treatment is a common method in Sulawesi, and the local area also produces a lot of Rob beans.
