Cadbury Dairy Milk A century of chocolate experience When John Cadbury first made drinking chocolate in Birmingham in 1824 using a simple pestle and mortar, he could never have dreamt that his family business would become one of the world's biggest and best loved chocolate manufacturers. Cadbury Dairy Milk, the UK's favourite chocolate, was first launched in 1905, setting new standards in quality and taste, which remain the hallmarks of Cadbury today.
