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) that are intended, as its name suggests, to be used as after-dinner mints. They were created in 1962 by Rowntree and 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. After Eights are now sold across Europe and North America, where they are kosher certified by the Orthodox Union, and one billion After Eight mints are made annually
In 2010, Nestle announced the closure of the Castleford factory, and the transfer of the production of After Eight to its Essex factory.
In 1967, After Eights were also manufactured at the Rowntree factory in the Wandsbek district of Hamburg.
After Eights were originally made from dairy-free dark chocolate. However, in 2007, Nestlé started adding butterfat to After Eights, making them a dairy product. Nestlé has also made special editions of After Eights, including orange After Eights and milk chocolate After Eights.
