Sumatra Coffee beans introduce Sumatra

Sumatra coffee cultivation began in the 18th century and was first introduced to the northern part of Sumatra, where Lake Toba, Sumatra's largest freshwater lake, is still the main source of Sumatra coffee. Because Sumatra coffee does not differ greatly in taste from region to region, and even coffee from different regions is harvested and processed very similarly, Sumatra is not named as a variety of coffees according to region. In fact, most of the coffee beans grown in Sumatra are sold under the product name Mantenin, which itself has ethnic connotations.

It is said that in World War II, when the Japanese occupied Indonesia, some Japanese soldiers went to a coffee shop run by Mantenin to drink coffee. They thought the coffee served by the owner was very good, so they asked the owner about the name of this coffee. The owner mistakenly thought that they were asking who they were and replied that they were Mantenin. Therefore, the Japanese soldiers thought that this coffee was called Mantenin. Later, one of the Japanese soldiers decided that the coffee they had drunk in Indonesia was of great commercial value and wanted to introduce it to the Japanese market, so he contacted an Indonesian businessman and asked him to buy "Mantenin" coffee. The shrewd businessman did not reject the deal because there was no coffee called Mantenin, but shipped 15 tons of Sumatra coffee to Japan. Before that, the high-quality Indonesian coffee had never been exported to any country, and since then, the name "Mantenin" has spread all over the world.

Mantenin coffee is grown at an altitude of 750 to 1500 meters, belonging to the rare Arabica coffee species in Indonesia.
