The shape of the logo is oval and circular, suggesting the oval form of the truffle. The colors used are only two, white and brown, representing the name and range of color shades of the Istrian white truffle. The font is in the Garamond typeface, suggesting tradition, exclusivity, and high product value. The stylized logo features the Croatian and Italian name of the product (Istarski bijeli tartuf / Tartufo bianco d’Istria) respecting the bilingual nature of the region. The year 1929. represents the first written record of the discovery of a large white truffle in the Istrian Peninsula. Within the circular logo are a stylized oak tree and a dog. The oak, as indicated by the shape of the leaves, represents the most common host plant species that establishes mycorrhiza with the Istrian white truffle. The sparse crown and not fully fallen leaves symbolize the beginning of the Istrian white truffle harvesting season, which is late summer and early autumn. The stylized dog in the form of a hunting dog (with drooping ears) is shown in a searching stance, sniffing among the oak roots, and represents the traditional method of finding truffles. The size ratio of the dog and the oak indicates that the oak is low, representing the predominant cultivation form in forest management on the peninsula, namely coppice and medium forests. The truffle is not shown on the stylized logo because it is hidden beneath the soil surface, which is in accordance with the logo’s tagline – Europe’s Hidden Treasure. The logo does not feature regional, national, or European symbols to suggest that the Istrian white truffle, although protected in a specific area, is a natural treasure of a broader region.
