What are the characteristics of Indonesian coffee and how to grade raw beans

Asia is the largest continent in the world, with complex and diverse topography, mainly mountains, plateaus and hills, with many volcanoes. With an average elevation of about 950 meters, Asia is the highest continent except Antarctica.

In addition, due to the large area, Asia spans the cold, warm and hot zones, and the climate type is complex, while coffee is mainly grown in Southeast Asia and South Asia, which is mainly the humid tropical monsoon region. With a suitable climate and rich water resources, coupled with the fertile soil given by volcanic ash, agriculture in Asia is developed, and there are many coffee-producing countries, such as China, Vietnam, Indonesia and so on.

Among them, Indonesia has become the fourth largest coffee producer in the world, and Indonesia's high production benefits from the country's unique terrain and climate. Indonesia is the world's largest archipelago country, composed of 17508 islands, with the title of "country of ten thousand islands". Therefore, the terrain is diverse, the interior of the islands are rugged mountains and hills, in addition, Indonesia is a multi-volcanic and multi-river country, there are about 400 volcanoes in the country.

In terms of climate, Indonesia is located in the tropics and across the equator, mainly belongs to the tropical rain forest climate, the annual average temperature is between 25-27 ℃, most of the climate is warm and humid, the mountain temperature is low, the annual drought and rain two seasons. With fertile volcanic soil, rich water resources and suitable climate, it is an ideal area for growing coffee.

Coffee is grown in several islands in Indonesia, and coffee producing areas are also divided by islands. Currently, coffee is mainly grown in Sulawesi (Sulawesi), Bali (Bail), Java (Java) and Sumatra (Sumatra).

The most famous of these is Sumatra, which is famous for its caffeine manning, which is not a coffee variety or a place name, but an ethnic group on the island. At first, during World War II, a Japanese officer asked the name of the coffee when he had a good cup of coffee on the island, but because of the language barrier, he was asked where you are from outside the store, so he replied "Mandheling Mandaining". Later, due to pronunciation and translation, it finally became Mantenin and is still in use today.

Sumatra, the largest island in Indonesia, consists mainly of the Barisan Mountains Mountains in the west and the lowland plains in the east. The Barisan Mountains Mountains, which run through the island, are home to more than 90 volcanoes, fertile soil brought by volcanoes, and more lakes. It can be said that the island is very suitable for coffee cultivation. Robusta varieties are mainly grown in the south of the island, while Arabica is grown in the north, concentrated in the Gayo-producing areas of Mount Gayu in the Aceh Special Administrative region and Lintong-producing areas in Lindong, North Sumatra province.

Among them, the Lindong producing area is located in the south of Medan, the capital of the island, and coffee is mainly grown in the volcanic area around Lake Toba Lake in the middle of the producing area. Lake dopa is a plateau lake and the largest volcanic lake in the world, but it is high above sea level. Coffee is grown on a hillside of 1400-1800 meters, and the annual average temperature is 22 ℃.

According to the Indonesian national standard, the grading of raw coffee beans mainly depends on the score of defects, and the defects of raw beans are based on 300g samples. in addition, TP (three hand selections) and DP (twice hand selections) are common in raw bean rules, and the number of TP defects is not more than 5 and the number of DP defects is not more than 9.

Qianjie coffee rations bean series also includes Indonesia, a well-known producing area of Sumatra, Lindong coffee beans, selected in the Ateng variety (Katim Catimor,Ateng for the local name), the use of wet planing, deep baking, brewing herbal, dark chocolate flavor, caramel-like mellow taste, high sweetness. Qianjie Coffee believes that Indonesia is the fourth largest exporter of coffee and the largest exporter in Asia, unlike coffee beans in Africa, which have high acidity, but high alcohol thickness, and are characterized by the aroma of spices and herbs. very able to express the regional flavor of Asia and Indonesia.
