The foregoing has described the 'wet' method of preparation to the point where it shares a common path with the 'dry' method, which will now be considered. 2. Dry Processing The 'dry' process is relatively more straightforward and usually more economical. Generally speaking the coffee cherry is left on the tree rather longer, and may be stripped from the branches instead ofbeing individually selected. Leaves and other unwanted material may be removed in the field and the coffee transported to the drying ground, which ideally should be of smoothly finished concrete, although the small farmer will often spread his cherries on strips of matting placed on the bare earth.

Whatever the system used, the drying time and drying temperature have to be carefully controlled to achieve maximum throughput without damage to quality. After this stage the coffee is known as dried parchment or pergamino, and since its quality is re1atively stable it is customary to store the beans in this state until shortly before exportation, when they are passed through the final stages of c1eaning, hulling and grading. The foregoing has described the 'wet' method of preparation to the point where it shares a common path with the 'dry' method, which will now be considered.
