coffee bean

A coffee bean is a fruit from the Coffea plant and the source for coffee. It is the pip inside the red or purple fruit. This fruit is often referred to as a coffee cherry, and like the cherry, it is a stone fruit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans. The fruits most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two, called a "peaberry". The peaberry occurs only between 10% and 15% of the time, and it is a fairly common (yet scientifically unproven) belief that they have more flavour than normal coffee beans. Like Brazil nuts (a seed) and white rice, coffee beans consist mostly of endosperm. The two most economically important varieties of coffee plants are the Arabica and the Robusta; approximately 60% of the coffee produced worldwide is Arabica and ~40% is Robusta. Arabica beans consist of 0.8–1.4% caffeine and Robusta beans consist of 1.7–4.0% caffeine. As coffee is one of the world's most widely consumed beverages, coffee beans are a major cash crop and an important export product, accounting for over 50% of some developing nations' foreign exchange earnings. This has made coffee very important in culture and food around the world. In 2017, 70% of total coffee production was exported, worth US$19.9 billion. History Significant dates According to legend, the coffee plant was discovered in Ethiopia by a goat herder named Kaldi around 850 AD, who observed increased physical activity in his goats after they consumed coffee beans. The coffee plant was first found in the mountains of Yemen. Then by 1500, it was exported to the rest of the world through the port of Mocha, Yemen.
