Coffee is a brewed drink prepared from
roasted coffee beans, the seeds of berries from certain Coffea species.
From the coffee fruit, the seeds are separated to produce a stable, raw
product: unroasted green coffee. The seeds are then roasted, a process
which transforms them into a consumable product: roasted coffee, which is
ground into a powder and typically steeped in hot water before being
filtered out, producing a cup of coffee.
The earliest credible evidence of coffee-drinking as the
modern beverage appears in modern-day Yemen from the middle of the 15th
century in Sufi shrines, where coffee seeds were first roasted and brewed
in a manner similar to how it is now prepared for drinking. The Yemenis
procured the coffee beans from the Ethiopian Highlands via coastal Somali
intermediaries, and began cultivation. By the 16th century, the drink had
reached the rest of the Middle East and North Africa, later spreading to
Europe.
