In Switzerland, the appellation d'origine protégée (French pronunciation: [apɛlasjɔ̃ dɔʁiʒin pʁɔteʒe], lit.
AOP [a.o.pe]) is a geographical indication (see also Appellation) protecting the origin and the quality of traditional food products other than wines (wines have another label called appellation d'origine contrôlée, AOC, 'controlled designation of origin').
In the past, the appellation d'origine contrôlée certification was used for both wines and other food products.
The appellation d'origine protégée (AOP, protected designation of origin) certifies that "everything, from the raw material to the processing and the final product, comes from one clearly defined region of origin".
