Coffee beans are the seeds of the Coffea plant in the Rubiaceae family, surrounded by
brightly colored berries. The raw beans, which are mostly bluish-brown, undergo an elaborate roasting process to become the raw
material for coffee drinks. Generally, several species of the rubiaceae family of coffee plants have been bred to produce beans,
but two of them account for nearly all the world's coffee production: Coffea Arabica, commonly known as Arabica, accounts for more than 70 percent of the world's coffee production; The other is Coffea Canephora, also known as Robusta coffee for its best known variety. There is also Coffea Liberica, also known as Liberian coffee, which has twice the size of the fruit and a smaller market
share.
