Indonesian Coffee Heritage

Indonesia is the world's largest archipelagic nation. Arabica coffee was introduced during the Dutch colonial period in the 18th century, and only in modern times has Indonesia become one of the top five coffee-producing countries globally. The main coffee-growing regions are located on the islands of Sumatra, Java, and Sulawesi.

This specially selected coffee comes from the Gayo region in Aceh Province, located in high-altitude mountainous areas. Indonesia, straddling both sides of the equator, has a humid tropical rainforest climate with abundant rainfall and fertile volcanic soil that provides rich nutrients for coffee. However, due to its remote location and inconvenient transportation, coffee cultivation didn't begin until 1924. Most farming uses traditional shade-grown, pesticide-free organic cultivation methods.

The Legend of Mandheling

Mandheling seems to have become synonymous with Indonesian coffee, but in reality, Mandheling is neither a region name, place name, nor variety name. Instead, it comes from a phonetic error of the Mandailing people from Sumatra. During World War II, when Japan occupied Indonesia, a Japanese soldier tasted an exceptionally mellow coffee and curiously asked the owner what kind of coffee it was. The owner mistakenly thought he was being asked where he was from and replied: "Man-te-ning." After the war, the soldier asked traders to ship this coffee back to Japan. After it became extremely popular, Mandheling coffee was thus created.

Golden Mandheling Excellence

To improve the high defect rate in Mandheling beans, Japanese traders implemented stricter quality control years ago, conducting four rounds of manual bean sorting to remove defective beans, producing uniformly large "Golden Mandheling" beans. Do larger beans necessarily taste better? Experience suggests this is true! Perhaps we can infer that because the beans are large and have good appearance, they receive more careful handling during the green bean processing process, resulting in better quality. Moreover, they heat evenly during roasting, offering better flavor control and consistently producing excellent flavors and mouthfeel!

Coffee Processing Methods

Coffee processing refers to the process of transforming mature red coffee cherries into dried green beans. Each processing method has its advantages and disadvantages, influenced by different natural environments and needs in producing regions. Therefore, each producing region has its suitable processing methods.

This particular batch uses the unique semi-washed processing method (Semi-washed) native to Sumatra, Indonesia, also known as the wet-hulled method. Due to the humid local climate, the parchment coffee undergoes preliminary washing and fermentation, followed by one to two days of sun exposure. Although the moisture content of the green beans is still 30-50%, the parchment hull is removed first before continuing the drying process to shorten the overall drying time. After approximately 2 more days of drying, the moisture content of the coffee green beans can be reduced to 12-13%. Indonesians call this unique semi-washed processing method "Giling Basah" (wet-hulled method).
