SMALL-SCALE COFFEE PROCESSING
Grinding Grinding is a means of adding value to a product. However, it is fraught with difficulties. With a whole product it is easy to assess its quality, whereas with a ground product it is very hard. The fear of adulteration and the use of low quality produce is justified. Because of this there is a great deal of market resistance to ground ...
