Nestlé is extending its Wonka range of children's countlines with the launch of Wonkalate on August 28. The purple, raspberry flavoured bar with green "snozzberry" flavour nerds spells out the name Wonka. Based on Roald Dahl's Willie Wonka's Chocolate Factory concept, it follows last year's launch of Wonka's Xploder bar. Wonkalate will be supported by a £500,000 media campaign, which includes advertising in magazines aimed at six to 12 year olds.
