Coffea plant belongs to the Rubiaceae family. It is an evergreen with beautiful opposite, glossy, dark green, oval leaves with slightly wavy edges. The flowers are white, grouped in clusters, starry and very fragrant. The fruits, called drupes or cherries, which they resemble in color and size even if they have a more oval shape. As maturation proceeds, the skin changes color, going from green to yellow until it reaches a bright red, dark orange and purplish depending on the origin. The coffee fruits grow continuously along the branches and ripen in a period of between 8 and 12 months.
Maturation is linked to the amount of sugar present in the fruit: the more sugar there is in the fruit more is better.
Some producers believe that a mix of cherries with various degrees of ripeness adds complexity to the coffee, it being understood that the fruits must never be very ripe or unripe, because this would lead to an unpleasant flavour.
