The coffee plant


Coffee is made by mixing dry roasted and ground coffee beans with hot water.

The coffee drink itself is made by extracting caffeine and a number of other substances and oils from the coffee beans in hot water.

Coffee beans are actually berries that grow on 2-meter high coffee bushes.

Coffee has traditionally been harvested by handpicking, and this technique still gives the best result, because only the correctly matured berries are picked. This inhibits the bitter taste from immature and overripe berries. However, automatic harvesting is becoming and more used, because it is a more rational harvest method, from an economical point of view.

After the harvest, the coffee is processed so that the coffee kernel can be removed from the coffee pulp. This can be done in one of two ways:

  1. Dried coffee: The method gives more substance, but also less coffee taste
  2. Washed coffee: This method gives a more pure taste and a better conservation of the aroma


The substances are created in different stages of the coffee producing process. The taste quality is dependent on how the coffee was grown, the soil the plant was grown in, the pre harvest processing of the beans, the coffee roasting and grinding processes and eventually, how the coffee was brewed.


The coffee bushes grow in the tropical belt around the equator. Australia and Brazil are the two most southern countries, and India and Mexico the two most northern countries that produce coffee.


The two main geological factors that determine the quality of the coffee are the height above the water surface and stable temperatures.


The word “coffee” is derived from the Arabic word “Qahwa”.
