When ordering a cup of Joe at a cafe or placing a coffee bean order online, it is important to know what type of bean the coffee drink consists of. Whether it's vendors such as Damn Fine Coffee or any other, there are two basic types of coffee beans on sale all around the world - Arabica and Robusta. Arabica is, by far, the most popular variety of coffee beans in the world. Coffee lovers love the mild taste of this bean, which has a sweeter flavour and can be consumed straight without diluting it in other ingredients. Ironically though, Arabica beans do not have as much caffeine content as Robusta which is not only less expensive but stronger in flavour. Used in instant coffee mixes and powders, a cup that is infused with Robusta beans can really kick some energy into your body.
