One of the best flavor you can find in Speciality Coffee coming from Natural process coffee.
Most harder and longer processing protocol as result provide us reach and fruity test in coffee. Natural process implies drying coffee cherries (yes yes, we call coffee berries - cherries :) without depulping, naturally.
Mostly coffee come to drying beds after skin removal (depulping) or washed in big water tanks (lavado, "washing" process). As result, most tasty mucilage which contains a lot of sugar, flavor and organic chemical constructions drain out with water.
Despite 30-days drying period (for example lavado will take only 3 days for drying) from my prospective natural are most tasty and best processing protocol of coffee.
