In 2001, the I Edition of the Truffle Monographic Fair, FITRUF, was held. It is celebrated every year in December in the Teruel town of Sarrión and is organized by the Sarrión City Council, with the collaboration of other public administrations, financial entities and associations of the sector. The organization of this monographic fair on truffles in Sarrión does not respond to an arbitrary fact, but is due to the fact that this town, located in the Sierra de Javalambre, meets, according to the experts, one of the best conditions in Europe for the cultivation of this precious mushroom. Therefore, FITRUF was born, as a professional, sectorial and monographic fair, mainly aimed at professionals in the sector. It should be noted that, in parallel to the Fair, every year a series of conferences is organized, exclusively for professionals in the sector, which edition after edition enjoy great acceptance among attendees, both for the quality of the talks and for the preparation of the speakers. In this report we take a historical tour of the fair analyzing its impact on the town and the region and its future projection.
