Wispa

Wispa is a brand of chocolate bar manufactured by Cadbury UK. The bar was launched in 1981 as a trial version in North East England and with its success it was introduced nationally in 1983. It was seen as a competitor to Rowntree's Aero (now owned by Nestlé). In 2003, as part of a relaunch of the Cadbury Dairy Milk brand, the Wispa brand was discontinued and the product relaunched as "Dairy Milk Bubbly". As part of the relaunch, the product was reshaped as a standard moulded bar (similar to other 'Dairy Milk' products) instead of a whole-bar count-line. However, in 2007, helped by an internet campaign, the Wispa bar was relaunched, albeit for a "limited period". In October 2008 Wispa returned again to shops in the UK and Ireland due to the chocolate bar's popularity during the previous limited period release.

Manufacture

The tiny bubbles within the chocolate are formed by aerating the molten chocolate with gas, typically carbon dioxide or nitrogen, while at a high pressure, which causes microscopic gas bubbles to form within the liquid. The liquid is then brought down to atmospheric pressure as it cools, causing the gas pockets to expand and become trapped in the chocolate.
