Coffee is grown in over seventy countries, from Indonesia to Brazil. Yet the total production of coffee is relatively small because it is such a fussy plant. Even though we call it a coffee bean, this is a misnomer. The little pod that is roasted, ground and brewed is actually the seed of the fruit that grows on the coffee tree. The coffee tree grows to twenty feet as a rule, but can reach heights of 45 feet. Most of these seeds come in pairs. There is one, called the pea berry, that looks like a cranberry with a sweet pulp and covered with a silvery membrane. Coffee grows in a band of about 25 degrees to the north and to the south, near the equator that encirlces the world. The reason for the concentration in this area is because coffee requires temperatures between 60F (15C) and 70F (21C) and a rainfall of six inches per month or more. In addition, coffee needs a specialized soil that is loamy and well drained. High humidity, found in mountain areas is also ideal. Diffused light and light breezes are also part of ideal conditions. Since oxygen is scarce at these altitudes, the trees mature slowly. All of these conditions cause the output of coffee to be low.
