Businesses involved in the manufacture of chocolate turn cocoa ingredients, sugar and other components into finished products for sale to retailers, food businesses or directly to consumers. Production can include roasting and processing cocoa beans, mixing and refining ingredients, conching, tempering and moulding chocolate. Some manufacturers make chocolate from cocoa beans, while others use prepared chocolate or couverture as the starting point. Typical products include chocolate bars, blocks, buttons, truffles, filled chocolates, seasonal shapes and chocolate coatings for biscuits, confectionery or desserts. Manufacturers may also produce products with nuts, fruit, caramel, fillings or alternative ingredients, and package goods in bulk or retail formats. Some provide contract manufacturing or make products to a customer's specification.
