Coffee cherries are drupes (stone fruit), but unlike more familiar drupes such as peaches and apricots, they are grown for their seeds (coffee beans) rather than for their flesh.
Each cherry usually contains two coffee beans. According to the National Coffee Association, a single coffee tree produces about 10 pounds of coffee cherries a year, which equals about 2 pounds of green coffee beans.
If you are planning on brewing coffee at home, the obvious questions would be, Where do you start?
You start with control. Why control? Because this an experiment, and you want to control all the variables of brewing coffee at home.
