- dry process
Dry process is a method to transform coffee from the fruit of the coffee tree to the green coffee bean, ready for export. Dry processing is the original method, and the wet process was devised later (as well as the very recent pulp natural process). It is a simple method, using less machinery and more hand labor, and has been a tradition in some growing origins for centuries. It risks tainting the coffee with defect flavors due to poor handling, drying, or ineffective hand-sorting. In dry processing the fruit is picked from the tree and dried directly in the sun or on raised screens, without peeling the skin, or any water-based sorting or fermenting. The dried coffee turns to a hard, dark brown pod, and the green seed is torn out from the skin and parchment layers in one step, or pounded out by hand. Because there is no chance to skim off floating defects, or removed under-ripes as with the wet process, most defects must be removed visually, by hand. Dry process coffees generally have more body and lower acidity than their wet process counterparts, with more rustic flavors due to the long contact between the drying fruit and the seed. They also can have more defects, taints, and lack of uniformity both in the roast and in cupping. A dry process coffee is sometimes referred to as natural coffee, full natural, or traditional dry process, or abbreviated DP.
