The coffee beans in your kitchen are the roasted seeds of the Coffea plant species in the genus Rubiaceae. These plants bear fruit, the coffee cherry, which farmers harvest. They then extract seeds from the fruit to yield green coffee beans.
Once harvested and dried, these coffee beans undergo processing, milling and roasting. Once that’s all taken care of, we get roasted coffee beans from which we brew coffee.
Where Do Coffee Beans Come From
If you’re an absolute coffee devotee like I am, it would please you to know that there are over 120 known coffee plant varieties. However, only four species – Coffee arabica, Coffea robusta, Coffea liberica and Coffea excelsor – are well-known.
Coffee shrubs have dark green waxy leaves distributed in pairs along woody-stemmed branches. These evergreen perennial shrubs (coffee trees) can grow up to 20 feet (6 meters) high in the wild. Farmers prune coffee shrubs to approximately 5 feet (1.5 meters) to enable them to harvest coffee cherries and improve productivity.
