Aero is a chocolate product manufactured by NestlÃ©. It was originally introduced to the North of England as the "new chocolate" by Rowntree's in 1935. By the end of the year, it had proved so popular with consumers that sales were extended throughout the UK. By 1936, sales of the chocolate had spread to New York City, and has since spread to many other countries including Canada, Mexico, Australia, South Africa and Japan. Aero has been manufactured by NestlÃ© since 1988 after they absorbed Rowntrees.
Known for its unique "bubbly" texture that collapses as the bar melts, it is available in many different forms including Aero Bars and Aero Biscuits, and originally had a mint flavour.
The process of manufacture was patented in 1935 by Rowntree's in York, England.
In 1935, Rowntree's launched Aero Mint into the UK, followed by the milk chocolate variation in the 1970s. The wrapping was green (brown in the chocolate version) and displayed the "Rowntree's" script logo and the large word "AERO", along with the slogan "Hold on tight or I'll fly away!" below the "AERO" name. The words "Aerated Mint Chocolate" ("Aerated Milk Chocolate" for the chocolate version) were seen multiple times in the word "AERO." In the 1970s, an advertisement was aired in which kids flying a kite thought the kite was an Aero bar.
There are several flavours of Aero. These include the Original Aero (which consists of milk chocolate throughout), Mint Aero (with a green, bubbly, mint-flavoured centre, covered in milk chocolate), Caramel Aero (with a caramel layer on top of the chocolate layer), Dark Chocolate Aero, White Chocolate Aero, Latte flavour Aero and Crispy Aeros (similar to NestlÃ© Crunch bars). Orange Aeros (orange/chocolate layered) were sold for a while as well, and larger 100 g sized bars are currently available in some stores. In the 1970s there were also Strawberry flavour bars. In the UK, and recently Canada, Aero Bubbles are also available. These are small, round chocolates with a bubbly centre, available in Milk Chocolate, Mint and Orange flavours and a mixture of both. In May 2012, Aero Orange and Aero Bubbles Orange were both introduced in Canada and in the UK as a limited edition. In January 2014, customers in Canada reported on two new flavours of Aero Bubble Bars that arrived in shops; a Strawberry flavour and a new variation of a Caramel Aero. While bars were (and still are) produced with chocolate and a liquid caramel, the new Caramel Bubble Bar consists of a Caramel flavoured white chocolate centre with a milk chocolate coating.
