Percentage
In recent years it has become common for premium chocolate products to display a percentage on the packaging. This percentage refers to the portion of the chocolate that is made up of cocoa beans. The higher the percentage, the less sugar is present. The percentage of cacao solids includes cocoa butter, and extra cocoa butter is often added to chocolate either to make it more suitable for processing or as a cost saving measure (cocoa butter can be cheaper than chocolate liquor). Because the percentage of cocoa solids is not further broken down into cocoa butter and chocolate liquor, this figure is only a rough guide to flavor and composition. One 70% bar may taste darker than another.
