Coffee bugs, in the previous few issues we learned about the origin and spread of coffee, so where does the coffee we drink today come from? Next, follow Little One to explore coffee-producing regions around the world~ Currently there are 53 major coffee-producing regions globally, all distributed within the Coffee Belt 『25°N～30°S』.

Their coffee flavor spectrum is broad and complex, with the greatest amplitude: from rough earthy, woody, leathery, medicinal, and fermented tofu off-flavors, to charming jasmine, cinnamon, cardamom, clove, pine and fir, mint, lemon, citrus, berry, apricot, smoked plum, chocolate... thousands of aromas and flavors, both good and bad, constructing an old-fashioned flavor spectrum that makes people love and hate it at the same time. Ethiopia has the world's most diverse coffee cultivation system and a complex ancient superior gene pool, plus diverse processing methods including natural, washed, and semi-washed, presenting complex and changeable flavors. It can be said that the "flavor spectra" of coffee-producing regions around the world can mostly be tasted here, reflecting Ethiopia's all-embracing "king's flavor."
