You might enjoy a cup of coffee at your local coffee shop. But coffee is part of an international industry. Research shows that as many as one-third of the people in the world drink coffee. Some people drink coffee for its rich smell and taste. Others like the awakening effect of caffeine, a chemical in coffee. But not everyone may know the story of coffee and how it is produced.
   One popular story about the discovery of coffee long ago is about Kaldi, a keeper of goats. Kaldi was taking care of his goats in the highlands of Ethiopia where coffee trees have grown for centuries. He noticed that his goats became very excited and active after eating small fruits from a tree. Kaldi reported this discovery to a group of religious workers. When they made a drink out of the fruit, the religious workers realized they could stay awake for long hours of prayer. This knowledge about coffee soon spread all over the world.
   Coffee trees are native to eastern Africa and areas of the Arabian Peninsula. Coffee was first grown and traded in the fifteenth century. Most coffee came from what is now Yemen. Soon, coffee was in high demand all over the Middle East. By the seventeenth century coffee had been introduced to Europe. European traders started bringing coffee plants to other parts of the world. The Dutch brought coffee to the islands of Indonesia. And by the twentieth century, most of the world’s production came from Central and South America. Today, Brazil is the largest producer of coffee in the world.
   Most people know what a coffee bean looks like, but what about the plant? Coffee trees can grow up to nine meters high, but they are cut short for production. These trees have shiny dark green leaves that grow on opposite sides of each other on a stem. The plant produces a fruit that is called a coffee cherry. When the coffee cherries are ripe and ready to pick, they are bright, red and firm. Inside the fruits are the green coffee beans. After these beans are roasted at high temperatures they are ready to be made into a drink.
