A coffee bean is a seed of the coffee plant. This cavity is inside the red or purple fruit, which is often called cherry. Just like normal cherries, coffee fruit is also a so-called stone fruit. After harvesting the coffee fruit, its flesh is removed and thrown away, leaving only the seed. Before roasting, the beans are gray/green in color and are called green coffee. Coffee beans are sold with the same color. Different types of coffee are divided into two main categories: Robusta or Arabica. Sanblah Tehran company has imported robusta (raw) green coffee beans with high quality and reasonable price.
