What is Coffee?

Coffee is arguably the most popular hot beverage in the world. It is made from the berries, or commonly known as coffee cherries, harvested from species of the Coffea plants. There are between 25 and 100 species of Coffea plants, however, the two most important species are Arabica and Robusta.

History of Coffee

coffee history

How and when coffee was discovered is not known, however, legend has it that it was first discovered in Ethiopia centuries ago by a goat herder named Kaldi. He noticed that the behaviour of his goats changed after they ate the fruit from a coffee plant. They were energetic and could not sleep at night.

Kaldi then informed the local monastery of this strange happening and they made a drink from this fruit. They too experienced similar effects to that of the goats, and word of this fruit spread East to the Arabian Peninsula and across the globe.

Coffee Houses

As the popularity of coffee grew in the Arabian Peninsula, it was enjoyed in public spaces called coffee houses. The popularity of these coffee houses grew and quickly became the center of all kinds of social activities. You can compare these coffee houses with the coffee shops we know today. Many gathered there to socialise and to exchange news and important information.

These plants can grow up to 30 feet high and are covered in green leaves with coffee cherries growing along the branches. While they can live up to 100 years, they are most productive after 7 years and before 20 years.

Coffee Arabica


The Coffee Arabica plant species descent from the original coffee plants found in Ethiopia, and it is believed to be the first species to be cultivated.  70% of the world’s coffee is produced from this specific plant, and coffee produced from this plant is known to be mild and aromatic. Apart from being lower in caffeine, Arabica coffee (also known as mountain coffee) can be more expensive seeing as though the plants are more costly to cultivate and require special attention.

Coffee Robusta


30% of the world’s coffee is produced from the Coffee Robusta plant, and it is mostly used in blends and instant coffee. Compared to the Arabica plant, the Robusta plant is cheaper to cultivate as it is more resistant to disease and parasites and therefore requires less attention. This is due to the amount of caffeine found in the plant, which acts as a natural repellent against harmful insects. Robusta coffee is known to have a distinctive taste, and it also has a lot more caffeine than Arabica coffee.

Coffee Cherry

Once these cherries are pink or red in colour, they can be picked. When opening these cherries you will find two beans which will later on be used to make your favourite brew.

Apart from being the key ingredient of coffee, coffee cherries can also be used in butter, chocolate or even sorbet. It is packed with antioxidants and has all the benefits normally associated with coffee.

Fun Fact: There will sometimes only be one bean inside a coffee cherry, and this bean is known as a peaberry. It is considered to be sweeter than a standard bean and more flavourful.
