Learn about the basic types and origins of coffee beans

Coffee beans are the core ingredient of coffee, and their type and origin directly affect the flavor of coffee. The main types of coffee beans are Arabica and Robusta. Arabica beans are the most popular type of coffee beans, accounting for 60% to 70% of global coffee production.

Arabica beans are mainly produced in Colombia and Brazil in South America, and Guatemala and Costa Rica in Central America. The climatic conditions in these regions are very suitable for the growth of Arabica beans. Robusta beans are mainly distributed in Uganda and Ethiopia in Africa, and Vietnam and Indonesia in Southeast Asia. The lower altitude and high temperature environment in these regions provide ideal growing conditions for Robusta beans.

Understanding these basic coffee bean types and their main production areas will help us better understand the flavor characteristics of coffee and the impact of roasting degree on coffee flavor. Before discussing the roasting degree of coffee beans, mastering these basics can help us more comprehensively evaluate the flavor changes brought about by different roasting stages.

A comprehensive analysis of the degree of coffee bean roasting

There are obvious differences in the degree of roasting of coffee beans, from light roasting to dark roasting, and each degree of roasting has its own unique flavor characteristics. Light roasted coffee beans are usually kept for a shorter time during the roasting process, so more of the original flavor is retained.
