The brown coffee bean is a seed of the Coffea plant and the source for coffee. It is the pip inside the red or purple fruit often referred to as a cherry. Just like ordinary cherries, the coffee fruit is also a so-called 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; cherries or berries, most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two. This is 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 flavor than normal coffee beans. Like Brazil nuts (a seed) and white rice, coffee beans consist mostly of the endosperm.
Coffee, beverage brewed from the roasted and ground seeds of the tropical evergreen coffee plants of African origin. Coffee is one of the three most popular beverages in the world (alongside water and tea) and one of the most profitable international commodities. Though coffee is the basis for an endless array of beverages, its popularity is mainly attributed to its invigorating effect, which is produced by caffeine, an alkaloid present in coffee.
