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』. Based on the spread timeline of specialty coffee and the flavors of the origins, we can roughly group these regions into three major categories: Old World old-fashioned flavor category, New World improved flavor category, and Oceanic island flavor category. In this issue, Gain Knowledge will first present the Old World coffee introduction~ Countries that already had Arabica varieties before the 17th century are called the "Old World," led by Ethiopia (Ethopia), with Yemen (Yemen) and India (India) as followers. These three ancient coffee countries retain the most diverse Arabica bean gene pool and traditional natural processing method. 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."

The Starbucks secret menu once led baristas to learn how to make over 170,000 customized drinks, but the extremes of personalized orders are sparking controversy.

Coffee roasting is a journey through complex chemical changes. In this process, the Maillard reaction and caramelization play crucial roles. The Maillard reaction, proposed by French chemist L.C. Maillard, is a series of non-enzymatic browning reactions between reducing sugars and proteins or amino acids under thermal catalysis, bringing flavor, mouthfeel, color, and complexity to coffee. Caramelization occurs during first crack, when sugars are heated and dehydrated to produce caramel and volatile aldehydes and ketones, deepening the bean color and creating aromas of fruit, caramel, and roasted nuts. Roasting reduces the density of coffee beans, making them drier and more brittle, increasing permeability, and making the components easier to dissolve. This article provides a detailed analysis of the three stages of roasting and the profound effects of each reaction on coffee, and recommends representative coffee beans such as Front Street Queen's Estate, Front Street Blue Mountain No. 1, and Front Street PWN Golden Mandheling.

Nowadays, the names of coffee processing methods are becoming more and more varied, from anaerobic natural to low-temperature slow anaerobic washed, from black honey and red honey to enzyme washed, making one dazzled. Behind this complexity, there are actually two main threads: the birth of early processing methods was the result of the producing region's environment forcing it—for example, Indonesia's humid and rainy climate gave rise to washed and wet-hulled methods; while the evolution of contemporary processing methods stems from the consumer market's dual pursuit of flavor expression and traceability information.
