Roasted Coffee beans.
A coffee bean is the seed of the coffee plant (the pit inside the red or purple fruit). Even though they are seeds, they are referred to as 'beans' because of their resemblance. The fruits, coffee cherries or coffee berries, most commonly contain two stones with their flat sides together. In a crop of coffee, a small percentage of cherries contain a single bean, instead of the usual two. This is called a peaberry. Coffee beans consist mostly of endosperm that contains 0.8 - 2.5 % caffeine, which is one of the main reasons the plants are cultivated. As coffee is one of the world's most widely consumed beverages, coffee beans are a major cash crop, and an important export product for some countries. It is considered a regularly consumed beverage in the United States - as popular as soft drinks and even water - and because of the volume consumed, it is here that coffee is highest in demand.
Types
Species of coffee plant include Coffea arabica, Coffea benghalensis, Coffea canephora, Coffea congensis, Coffea excelsa, Coffea gallienii, Coffea bonnieri, Coffea mogeneti, Coffea liberica, and Coffea stenophylla. The seeds of different species produce coffee with slightly different characteristics.
There are two main types of coffee beans: Coffea Arabica (more commonly referred to as "Arabica ") and Coffea Canephora (Robusta). These two types make up over
90% of coffee beans sold worldwide. Arabica typically produce higher quality coffees, while Robusta are more economically favorable for their heartiness.[vague]Because environmental factors deeply affect the flavor of the beans, they are usually identified not by type but by geographic location.
