Coffee beans are the seeds of a fruit, known as the coffee cherry, which grows on coffee plants. These small, seemingly insignificant beans are the foundation of one of the world’s most beloved beverages, with a rich history, diverse flavors, and a multitude of health benefits. But what exactly is a coffee bean considered, and how does its classification impact the coffee industry? In this article, we will delve into the world of coffee beans, exploring their botanical classification, types, and the factors that influence their quality and flavor.
Botanical Classification of Coffee Beans
From a botanical standpoint, coffee beans are the seeds of the coffee plant, which belongs to the genus Coffea. There are over 100 species within this genus, but only two main species are commercially cultivated: Coffea arabica and Coffea canephora. Coffea arabica, also known as Arabica, accounts for approximately 60-70% of the world’s coffee production and is considered to be of higher quality due to its more delicate and nuanced flavor profile. Coffea canephora, also known as Robusta, is more disease-resistant and easier to grow, but its flavor is often described as harsher and more bitter.
Species and Varieties of Coffee Beans
Within the two main species of coffee plants, there are numerous varieties, each with its unique characteristics, flavor profiles, and growing conditions. Some of the most popular varieties of Arabica coffee include Bourbon, Typica, and Gesha, while Robusta varieties include Conilon and Excelsa.
