Sulawesi is an important coffee-producing region in eastern Indonesia, made up of four peninsulas, with the highest proportion of mountainous terrain in the country and an average elevation of over 500 meters. The Kalos coffee beans from the island belong to the Sumatra Typica variety, are large and plump, and are processed using the semi-washed method, producing a rich, mellow flavor with low acidity and a hint of herbal notes. The Toraja production area is located in the highland region slightly southwest of the island's center, at an elevation of about 1,200 meters, and is the region's most representative source of coffee. Sulawesi coffee accounts for only 7% of Indonesia's national output, but market demand is strong, and supply often falls short of demand. The Celebes Kalossi coffee that Front Street recommends paying attention to is a typical representative of this production area. [more…]

Indonesian coffee has long been known for its herbal, spicy character and full body with low acidity, but beans from Sulawesi take a completely different path—bright acidity and distinct layers that feel refreshingly new.

Recently, many parts of Asia have been hit by extreme weather, with Indonesia bearing the brunt. Torrential rain, floods, volcanic eruptions, and landslides have struck one after another, dealing a heavy blow to multiple industries in the country, and the coffee industry has been unable to escape unscathed.
