A geographical indication is a sign used on goods that have a specific geographical origin and possess qualities, reputation or characteristics that are essentially attributable to that place of origin. Most commonly, a geographical indication includes the name of the place or origin of the goods. Agricultural products typically have qualities that derive from their place or production and are influenced by specific local factors, such as climate and soil.
Three European Union schemes of geographical indications and traditional specialities known as protected designation of origin (PDO), protected geographical indication (PGI), and traditional speciality guaranteed (TSG) promote and protect names of quality agricultural products and foodstuffs. These laws protect the names of wines, cheeses, hams, sausages, seafood, olives, beers, Balsamic vinegar and even regional breads, fruits, raw meats and vegetables.
