Green coffee beans are essentially unroasted beans. Generally, in a raw form, all coffee beans are green until they are roasted. These beans are actually the seeds of the coffee berry and in order to get them, the flesh of the coffee berry is taken out, usually with the use of a machine. The berries have to be carefully sorted out according to their color and degree of ripeness and the flesh of the coffee berry removed, leaving the seeds, which in essence are normally referred to as the coffee beans. The coffee beans are then fermented to remove the slimy mucilage left coating the beans. The beans are then soaked and washed in lots of fresh water to further remove the residue left over from the fermentation process.
