Cofee is grown typically between the Tropic of Cancer and the Tropic of Capricorn where conditions are ideal for the species. There are two main branches of the cofee varietal, Robust and Arabica. Robusta is less favoursome, high yielding with high pest tolerance. Hence, it is great for cheaper, low-quality instant cofees. Arabica makes up the majority of the cofee grown in the world and is what holds the exciting favours and aromas that you think of when you dream of cofee. The cofee tree and its cherries can be a number of colours depending on the varietal. Mainly they are bright red, but sometimes they can be yellow. There a number of layers in the cofee cherry, before you get to the actual cofee bean that we know.
