PIRAN SALT (PIRANSKA SOL) with protected designation of origin (PDO) is produced according to an approved traditional procedure, according to an almost 700-year-old tradition and only with traditional tools. The basic process is natural crystallisation on salt-fields, where salt is collected on a bio-sediment base of a few millimetres thickness called PETOLA, composed of minerals and micro-organisms.

The harvest only depends on the forces of nature – of the sun, wind, sea, and the assiduous work of the salt pan workers. The salt from the Sečovlje Salina Nature Park is light, rich in minerals of the sea, and of an exceptional taste that provides dishes with extra culinary exceptionalness. In 2005, the company successfully completed the certification process carried out by Bureau Veritas, the authorised certification house of the Slovenian Ministry of Agriculture, Forestry, and Food, for a top-notch product with a long tradition – PIRAN SALT with the denomination of origin. In 2014, the European Commission entered Piran Salt into the Register of protected designations of origin and protected geographical indications, which is the highest level of protection within the framework of the European scheme of farming produce and food protection. With this, PIRAN SALT (PIRANSKA SOL) with protected designation of origin (PDO)  was set on an equal footing with the world-renowned products, such as champagne, Parma ham, Parmesan cheese and also Istrian olive oil.
