Geographical indications (GIs) are crucial for protecting the unique characteristics of products originating from specific places. They preserve the reputation and quality of traditional items, promote cultural heritage, and inform consumers about product origins and quality. Obtaining GI seals can be challenging as it requires reconciling traditional production methods with modern standards. However, the seal brings small producers and traditional products to the forefront, benefiting less-favored regions. GIs ensure consumers purchase products with known quality and reputation while allowing producers to differentiate and command premium prices. Moreover, GIs support regional development by adding value, attracting tourists, and boosting the local economy. Recognizing the value of traditional products and production methods, GIs preserve cultural heritage and encourage sustainable development. Thus, the aim of this review is to highlight the importance of GIs in regional development and traditional product appreciation from the example of the five cheeses with the protected GI seal existing in Brazil.
