Globally, the regions where coffee is cultivated are concentrated in a limited area known as the 'coffee belt', between 25˚ south and 25˚ north latitude. This area has the characteristics of a tropical climate, but it is not simply the hot temperatures that allow coffee to grow. Rather, it is the cool environment and shade of high altitudes that produce superior and high-quality coffee varieties, which is why Arabica coffee grown in mountainous regions is highly regarded worldwide.

For example, Yunnan Province in China and the highlands of Ethiopia both belong to the coffee belt and provide a cool climate, abundant sunlight, and suitable humidity. Here, Arabica varieties are primarily cultivated because the coffee trees grow slowly in a consistent temperature and humidity, resulting in more complex flavors and a smoother taste.

Many people think that coffee only grows in warm temperatures, but in reality, coffee trees are cultivated under cool shade using a technique called 'shading'. Coffee trees planted alongside shade-providing species such as rubber trees and inga trees can avoid the intense heat of direct sunlight, allowing them to grow under more stable temperature and humidity conditions. This shaded cultivation method not only improves the quality of coffee but also reduces the impact of coffee trees on the ecosystem and protects the soil and environment. In contrast, coffee grown in direct sunlight is referred to as 'sun coffee', which has somewhat different effects on the growing conditions and the taste and aroma of the coffee.

Brazil holds a dominant position in global coffee production. Its production volume is so immense that the global coffee bean prices can fluctuate significantly based on Brazil's coffee harvest. There was a time when Brazil faced severe crop failure, known as the 'Great Coffee Famine', which caused disruptions in the supply of coffee beans, putting global coffee chains like Starbucks at great risk. Thus, Brazilian coffee acts as a major factor that significantly influences the global coffee market beyond mere bean production.

In this way, global coffee production is greatly affected by the climate, altitude, and cultivation methods of specific regions. In the highlands of the coffee belt, the best Arabica coffee grows through cool temperatures and shaded cultivation, recognized for its excellent taste and aroma worldwide. On the other hand, sun coffee grown under hot sunlight possesses different characteristics, which may lead to varying taste profiles preferred by consumers.

Ultimately, behind the cup of coffee we enjoy in our daily lives lies a complex interplay of numerous environmental factors, sophisticated cultivation methods, and the climatic and geographical characteristics of each country. Most of the coffee consumed in Korea is made from beans imported from these coffee belt regions, particularly Brazil, Ethiopia, and Yunnan Province in China, capturing the unique characteristics of each area.

Considering the diverse stories and scientific, ecological backgrounds contained in a cup of coffee, doesn't it make our coffee time feel even more special and meaningful?
