The manufacturing process for chocolate requires much time and painstaking care. Making an individual-size chocolate bar, for instance, takes at least two-to-four days.
Manufacturing methods will differ in detail from one chocolate plant to another, but there is a general processing pattern which prevails everywhere. For example, all manufacturers carefully catalogue each shipment of cocoa beans according to their particular variety and region of origin. This is very important, because it enables the chocolate-maker to maintain exact control over the flavor-blending of beans in the roasting process. In the science and art of chocolate-making, precise blends are necessary to produce the flavor profile of each desired end product, whether that is a chocolate bar or fine boxed chocolate.
