Coffee is a brewed drink prepared from roasted coffee beans, which are the seeds of berries from the Coffea plant. The plant is native to subtropical Africa and some islands in southern Asia. The plant was exported from Africa to countries around the world and coffee plants are now cultivated in over 70 countries, primarily in the equatorial regions of the Americas, Southeast Asia, India, and Africa.

"Coffee" generally refers to a beverage made by the infusion, decoction or percolation of the roasted, ground seeds of the coffee plant* (genus Coffea, and usually C. arabica or C. canephora / C. robusta). Coffee is prized for its aroma and flavor, and is noted for the fact that it naturally contains varying levels of caffeine. In coffee cupping, traits of coffee like acidity and mouthfeel are also noted.

Aged Coffee, Vintage Coffee. Traditionally, coffee held in warehouses for several years, sometimes deliberately, sometimes inadvertently. Such aging reduces acidity and increases body. Aged coffee has been held longer than either old crop coffee or mature coffee. Recently, some Indonesia coffee has been subject to a sort of accelerated aging involving deliberate exposure to moist air, much like India’s monsooned coffee.
