Coffee is a brewed drink prepared from roasted coffee
beans, the seeds of berries from certain flowering plants in the 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 fine particles
that are typically steeped in hot water before being filtered out,
producing a cup of coffee.
