After Eights advert from 1980
After Eight Thin Mints (After Eights) are a confectionery product described as “mint enrobed in dark chocolate” (although a milk chocolate version became available in 2006) and are intended, as the name suggests, to be used as after-dinner mints. They were created in 1962 by Rowntree & Company Limited. Since the 1988 acquisition of the United Kingdom-based company, the mints have been produced by Nestlé.
The Thin Mints have been made in the factory in Castleford, West Yorkshire since 1970, whereas the Chocolate Truffles are made in York. After Eights are now sold across Europe and North America, and one billion After Eight mints are made annually.
