Did you know that it takes around 70 roasted coffee beans to make one cup of coffee? These 70 beans produce around 8 grams of coffee. To make this single cup, around 40 grams of coffee cherries need to be picked on the plantation. Several steps are required before the coffee beans can be roasted.
The two beans inside the coffee cherry, in fact the seeds, form the core (see illustration). During processing the pulp is completely removed, leaving the parchment, which is removed shortly before export. This process is known as hulling. Finally, all that remains is the silverskin around the bean.
During roasting the bean loses moisture, which reduces its wight by around 18% - 22%. By the time processing is complete, the weight has been reduced from the initial 40 g to 8 g.
