Coffee beans are the core ingredient of coffee drinks. They are actually the seeds of the coffee tree fruit.

The historical evolution and global spread of coffee beans

The history of coffee beans can be traced back to Ethiopia in the 9th century AD. According to legend, a shepherd found that his flock became unusually active after eating the berries of the coffee tree. This discovery gradually attracted the attention of local monasteries, who began to use coffee beans to make drinks to help stay awake and pray.

Coffee was introduced to the Arabian Peninsula in the 15th century and quickly became popular in Muslim society. In the 17th century, coffee was introduced to Europe through trade networks and became a favorite of the upper class in countries such as France and Britain. Coffee houses began to emerge in major cities such as Paris and London, becoming centers of social interaction and discussion.

Coffee’s global spread wasn’t limited to Europe. With colonial expansion, coffee cultivation also began to flourish in the Americas and Asia. European powers established large-scale coffee plantations in these regions, making coffee an important commodity in global trade.

Today, coffee is not only an everyday drink, but also part of global culture, influencing social habits, economies, and international trade. Its historical evolution shows how the coffee bean developed from a local discovery to a global phenomenon.

Main coffee bean types and their unique flavors

Coffee beans are mainly divided into two categories: Arabica beans and Robusta beans. Arabica beans are the most common type of high-quality coffee beans, accounting for the majority of global coffee production. Its cultivation conditions are relatively harsh, and it mainly grows in high-altitude areas. Arabica beans have a delicate flavor, with fruity and floral aromas and high acidity, and are generally considered to be the best coffee.

Robusta beans are very different from Arabica beans. They are drought-tolerant and pest-resistant and are mainly grown at low altitudes. Robusta beans have a high caffeine content and are usually stronger and more bitter, with woody and earthy flavors. This makes Robusta beans often appear in espresso to enhance the weight of the taste.

In addition to these two categories, there are some other varieties in the coffee market, such as Liberica beans and Excelsa beans, which have relatively small production and their own unique flavors. Liberica beans have a unique flavor with significant fruit and floral aromas, but they are more difficult to grow; while Excelsa beans are popular for their rich aroma and heavy taste.

Different types of coffee beans have different flavor characteristics due to their different growing environments and processing methods, providing coffee lovers with a wealth of choices. Understanding the characteristics of these types can help you better choose and enjoy various coffees.
