Most arabica coffee beans originate from either Latin America, eastern Africa, Arabia, or Asia. Robusta coffee beans are grown in western and central Africa, throughout southeast Asia, and to some extent in Brazil. Beans from different countries or regions usually have distinctive characteristics such as flavor, aroma, body, and acidity. These taste characteristics are dependent not only on the coffee's growing region, but also on genetic subspecies (varietals) and processing. Varietals are generally known by the region in which they are grown, such as Colombian, Java, or Kona.
Once roasted, coffee beans must be stored properly to preserve the fresh taste of the bean. Ideal conditions are air-tight and cool. Air, moisture, heat and light are the environmental factors[53] in order of importance to preserving flavor in coffee beans.
