Introduction to the Origin and Varieties of Coffee Beans

Coffee beans, as an indispensable drink in our daily life, come from the ancient coffee tree. The history of coffee can be traced back to Ethiopia in the 9th century AD. According to legend, after shepherds discovered the refreshing effect of coffee tree berries, the plant gradually spread to the Arabian Peninsula and became the main drink in the Islamic world in the 15th century. Today, coffee beans are mainly produced in tropical regions, including South America, Africa and Southeast Asia.

There are many varieties of coffee beans, but they can be divided into two main categories: Arabica and Robusta. Arabica beans are usually grown at higher altitudes and have a more complex flavor and less bitterness, while Robusta beans are grown at lower altitudes and have a stronger flavor and more bitterness. In addition, there are some other niche varieties, such as Liberica and Excelsa, which have their own characteristics and meet the needs of different consumers.
