Coffee is one of the most popular drinks in the world, with countless cups being consumed each day. Despite this, not many people know how coffee is actually produced. So how does the humble coffee bean reach our cups
Coffee beans are the seeds of the coffee plant, contained in small berries. When the coffee berry is at peak ripeness it is harvested from the plant and then sorted. The flesh of the berry is then removed and the bean fermented to remove the slimy covering left behind. The bean is then washed and left to dry.
Once the seeds are dry the beans are then roasted. Roasting is particularly important for the taste of the coffee, with different lengths and intensities changing the taste. Until the roasting process the coffee bean is actually green, it is here that they take on their iconic brown colouring. Roasting is generally done at around 200 degrees Celsius.
After roasting the beans are graded according to the degree of roasting: darker roasted beans are bolder and more sugary, while lighter roasted beans are more complex. The coffee is then placed up in air-tight packaging to prevent contamination of the flavour and shipped across the world, ready to be brewed.
