Processing is a short, but by far the most critical step in the journey of coffee which determines the final flavor profile of the berries.
Natural processed coffee seems to be the future since most of us were born into a world where washed coffee was already very popular. When the consumer is accustomed to consuming mostly washed coffee, it is but natural to look for something different and more exciting.
Just like consumption of coffee is explained in waves, processing of coffee at the farm can also be categorized in waves. Obviously, the first wave refers to the process used when humans first started consuming coffee. One need not guess that this process was the natural process. After the industrial revolution, production went up to meet growing demand and we needed a way to make larger volumes of more consistent product.
