The World of Coffee


Coffee was first discovered in the country we know today as Ethiopia. Of course, we don’t know exactly who brewed the first cup but there is a popular legend about its discovery. Apparently, a goat herder called Kaldi, noticed that his goats acted unusually friskily after eating berries from a bush. Curious about this phenomenon, Kaldi tried eating the berries himself and found that the berries gave him a renewed energy. The news of this energy laden fruit quickly spread throughout the region. Monks heard about this amazing fruit and dried the berries so that they could be transported to distant monasteries. On arrival, they reconstituted these berries in water, ate the fruit, and drank the liquid to provide stimulation for a more awakened time prayer time. Coffee first arrived on the European continent by means of Venetian trade merchants. Coffee houses spread quickly across Europe becoming centres for intellectual exchange and political activity.

These days there are two main types of coffee grown, Arabica and Robusta coffee. Arabica is generally more highly regarded but Robusta has a role to play too. Robusta can sometimes be bitter and have less flavour but it has better body. Robusta strains also contain about 40–50% more caffeine than Arabica. For these reasons, about three-quarters of coffee cultivated worldwide is Arabica.

Fresh coffee beans are green when removed from the fruit of the tree. It is the roasting process that changes them from green beans to the various shades of brown, depending on your roast preference. During roasting, heat causes acids to be formed and consumed, converted into sugars and other flavor compounds. Getting the roasting part of the process right is vital to making good coffee, so we pay careful attention to it here in Robert Roberts. Roasting affects taste, smell and colour. We vary roasting time, roast profile and outturn temperature to get the balance right between acidity and body while maintaining flavor notes. For example, dark roasts have lower acidity then lighter roasts of the same origin.
